Women on Ekofisk

person By Ragna Ervik
Does female identity fit with a male-dominated culture? This question has been explored by Ragne Ervik for a master’s thesis in social anthropology which focused on women working on Ekofisk.

Ekofisk was the first commercial petroleum discovery on the Norwegian continental shelf (NCS). Found in 1969, it came on stream as early as 1971.

This area lies at the southern end of Norway’s North Sea sector, about 280 kilometres south-west of Stavanger, and has been developed with a central complex and several satellite fields.

Working on Ekofisk has always been and remains very unlike a job on land. The most eye-catching difference is the need to fly. A helicopter flight takes 90-120 minutes, depending on weather.

While at work, personnel are completely divorced from life on land and experience a total physical separation from “normal” society.

People on Ekofisk are part of a small but complex community where platform operation is the common denominator. Most workers do fixed tours of duty – usually two weeks on and three-four off.

Offshore jobs were originally held exclusively by men. The first women only arrived in 1978, either as nurses or as catering personnel.

But Ekofisk remains a male-dominated arena, where women are in a clear minority at less than 10 per cent of the workforce. Catering has the largest proportion of females – just under 50 per cent. The share is significantly below 10 per cent in production and operation.

Male and female jobs

Although the bulk of the women now on Ekofisk still have jobs in the service sector, they are represented across all occupational sectors – platform management, drilling, production and operation.

The various types of work differ in their standing and prestige among those employed on the field and in the rest of society.

Social anthropologist Jorun Solheim believes that every kind of work has a gender dimension.[REMOVE]Fotnote: Solheim, Jorun and Ellingsæter, Anne Lise, Den usynlige hånd. Kjønnsmakt og moderne arbeidsliv, 2003, Oslo. By this, she means that society has generalised perceptions of “male” and “female” jobs.

A male job often relates to base or core functions in a workplace, with direct participation in what is being produced, while female work is defined as social and hygienic.

This means that a woman working in base functions on a platform, such as production, holds a “male” position and is perceived in terms of her job rather than her gender.

She is therefore judged differently from women engaged in more typically female work. So women in “male” jobs acquire a different standing both among her colleagues and in society at large from female workers in service trades. A women employed in the core area of a company works alongside men and is accepted by them. Solheim puts it this way:

The central issue is how the work itself is ‘genderised’. Particular work assignments and areas of expertise will be viewed as male or female respectively.[REMOVE]Fotnote: Solheim, Jorun and Ellingsæter, Anne Lise, Den usynlige hånd. Kjønnsmakt og moderne arbeidsliv, Oslo, 2003.

In other words, the job has a gender dimension. The individual worker is defined by the work he or she does – by whether it has a male or female character – and not by their actual gender. A man’s job has more standing and prestige than a woman’s.

So the question is whether the job done by a woman on Ekofisk determines how she is assessed, or whether gender in itself is decisive for how she is regarded and her place in the hierarchy. How are these women viewed by their female and male colleagues?

As mentioned above, most people on Ekofisk work defined tours – two weeks offshore and three-four weeks at home. But differences exist. Working conditions and tour arrangements vary between operator employees and contractor/service company personnel.

Those employed by the operator – in this case ConocoPhillips, formerly Phillips Petroleum Company – have the most stable jobs. Their tours are fixed and they travel offshore with the same people every time.

Service company employees, on the other hand, will complete an assignment on one platform and then move to a different facility. So they will not be on the same installation for a long period.

Their position is also to some extent unstable. The duration of their work depends on a specific contract between operator and contractor. This may run over several years and can either be extended on expiry or transferred to another contractor with new personnel and rules.

Whether they are operator or contractor personnel can influence people’s view of the work and not least the employee’s own perception of their job and the associated social life. The point here is that operator employees are considered to have the most important jobs offshore and can thereby feel themselves to be superior to others.

Education represents another important factor in the way a worker is regarded. Those with the highest qualifications often have the same educational attainment as their own managers, and thereby hold a kind of intermediate position between colleagues offshore and the land organisation.

Women in jobs which call for a high level of education avoid having to “compete” with the men in an arena where females have traditionally done less well because they lack male strength.

People with higher education and offshore experience are also qualified for a range of positions in the company, from production engineer to the partner relations department, for example. In other words, advanced technical qualifications, work in the core areas and permanent employment with the operator confer more standing than an unskilled temporary position or a job with a contractor/service company.

A skilled female technician employed by the operator has a position which awards prestige. She works in her employer’s core area and is a permanently employee.

Offshore nurses have a professional qualification and often additional training in a specialist field. They are highly educated and permanently employed by the operator. And, even though the same job on land is perceived as a female occupation, it has traditionally been a male preserve offshore.

That could partly reflect an inheritance from shipping. The first mate on a ship – a man – is often responsible for dealing with injuries. This means that the nursing function offshore has been redefined from a caring role to an expertise-based position and enjoys high standing. On the other hand, a women employed in drilling does not work for the operator but for a service company. In theory, that should indicate the job is less prestigious.

But drilling falls within the platform’s core area – no wells, no production. These workers make “first contact” with the oil or gas before it is tamed. A drilling job has a mythic quality, since it involves a certain level of risk, a level of expertise and a portion of good luck. This has traditionally been regarded as a job for the tough “lads”, and a woman who succeeds in this environment enjoys great respect. Even if she is employed by a service company, she will have high standing because of its “manly” character.

As contractors, the catering companies cover two occupational groups – the skilled cook and the unskilled cleaner. The latter has a service job traditionally associated with women, which has a female character in itself. Many cleaning personnel begin as temporary replacements before securing permanent employment, and few opportunities are available for career advancement. The work done is taken for granted and is not noticed until it has not been carried out. This provides an example of a job which confers low standing.

Spatial relationships

The platform’s spatial organisation works differently for women and men. Since the offshore environment is male dominated, arenas will exist where just men are present. But women-only places are seldom found.

Females are more or less always in mixed company and in a minority. A women thereby has few or no locations on a platform where she can simply be herself, without playing a part.

Social anthropologist Erving Goffman talks about people’s need for a “backstage” area. He divides social life into this and “frontstage”, or between private and public spheres.REMOVE]Fotnote: Goffman, Erving; Vårt rollespill til daglig: en studie i hverdagslivets dramatikk. Oslo 1992.

When backstage, no demands about behaviour are made and people can relax more. Frontstage is a place where they must think through and prepare their performance.

So men do not have to reflect how they appear to women when only males are present. Using Goffman’s terms, we can say that women have few backstage areas and men have more of them. This means that females must be more conscious of their performance for more of the time they spend offshore than is necessary for males.

Process engineers and nurses are examples of solo players. They will not “make a botch” of the way men in corresponding roles and at other times have done the job.

Authority

Women often lack the natural authority men possess, but can compensate for this by utilising spatial relationships to legitimise their organisational status.

An example of such conscious use of these conditions is the female offshore installation manager (OIM) who deliberately occupies the manager’s chair because those who enter her office are used to connecting it with the OIM. She wants to be associated with this role and uses spatial relationships to emphasise this.

Even though women do not control the physical or social space directly, they nevertheless exert an influence on how space is allocated and utilised.[REMOVE]Fotnote: Ardener, Shirley  Ground Rules and Social Maps for Women: An Introduction.  Women and space : ground rules and social Oxford  1993 

According to both oral and written sources, sales of after-shave in platform shops increased dramatically when women began working offshore.

Women have also exerted some influence on the design and utilisation of tools and other equipment. The Karmøy winch was developed because a female operator maintained that it must be possible to get equipment which made it easier to open valves.

Wall decoration, also part of the spatial dimension, is another area influenced by the women. After they started working offshore, fewer picture of more or less semi-naked models have adorned work spaces and offices.

Social relations

A platform is much more than a workplace. By extension, it is also a small but complex community on an artificial island where people live 24 hours a day.

This society is characterised by the need to perform many different functions and, in order to achieve that, people need to specialise.

Like the wider society on land, the Ekofisk community is complex because a great variety of activities have to be pursued. Some people are specialists on process, others on drilling or mud.

A complex society is also characterised by the fact that only partial identities are expressed through interactions in the various settings.[REMOVE]Fotnote: Solheim, Jorun and Ellingsæter, Anne Lise, Den usynlige hånd. Kjønnsmakt og moderne arbeidsliv, 2003, Oslo.

The expression “partial identities” means that people do not see the whole person in their job, but only that part which is “relevant” to what they are doing there.

Nevertheless, the fact that personnel live on a platform around the clock will allow more aspects of their personality to emerge.

Occupational identity is central, largely fixed – and not negotiable. What can be negotiated or personally determined is whether the time offshore will be positive, whether one is going to be social.

People put each other in social categories and simplify by creating stereotypes. Anthropologist Gregory Bateson sees this need for simplification as a result of information overload which requires us to bring things down to a more manageable level.[REMOVE]Fotnote: Solheim, Jorun and Ellingsæter, Anne Lise, Den usynlige hånd. Kjønnsmakt og moderne arbeidsliv, 2003, Oslo.

Statements such as “women in aspirational jobs … aren’t here long” about university-trained engineers reflect a stereotype of a feature or property of females with such qualifications.

It is easier to avoid leisure contacts with work colleagues on larger platforms. You can expect “somebody else” to be engaging in social interaction, so your absence will not be noticed.

Pressure to be sociable can be stronger on smaller installations, and you will feel under a greater obligation to be present in common parts.

It is particularly difficult for women to evade social relationships on a small platform because there are so few of them that their absence will be immediately noticed.

Job affiliation

Different levels of affiliation to the job appear to affect how a person integrates with the platform community. Those permanently employed offshore and in stable jobs – whether for the operator or a contractor on a long-term contract – are more assimilated.

This group includes personnel in both production and service roles – process operators, nurses, radio operators, administrators and catering employees. They are often well integrated in the platform community and also have friends among those they have met offshore.

The exception is the nurses. Even though they are well assimilated, a number of female medical personnel indicate that they avoid over-close relationships for professional reasons.

Highly educated technical personnel and service company employees are often less integrated because their jobs are not permanent.

The same seems to apply to managers in typical career posts. It appears that the higher up the hierarchy a person is, the more formal their relationships will be.

With the role structure more strictly defined, such people are required to behave more formally. Formal structures create clear divisions of roles and demands for bodily control.[REMOVE]Fotnote: Douglas, Mary; Natural Symbols explorations in cosmology London 1996.

A woman in a management position offshore seldom has female colleagues at the same level. Should the job also absorb most of her time, it is hard to become intimate with other women.

If they are at work the whole time, social interaction becomes part of the job and the boundaries between work and leisure get blurred. That applies primarily to nurses and OIMs, who are always on call.

Everything was better before

Those who have worked offshore for a long time have claimed that everything was nicer before. Typical comments include: “we were all more united then”, “there’s much more division now”, and “we had a much better time”.

The reason why earlier times were finer was that certain jobs had fewer responsibilities than today. And TV sets in cabins with masses of channels must take a share of the blame for people being less sociable.

Leisure activities

Various leisure activities are available offshore. These normalise the time spent there, and help to break up the routine of work, eat and sleep.

They help to make the time more meaningful. When a job is characterised by routine, a hobby which allows people to express their creativity can aid relaxation.

Male-female relations

Everyone believes that having both genders represented on the platforms is beneficial, even though some people were sceptical to begin with.

Where women work in relation to the men has an impact on their bonding. Those who interact closely with male colleagues usually have man-to-man types of association – friendship, collegial ties, a superior-subordinate relationship and so forth.

Most emphasise the importance of not ending up in woman-man ties, such as becoming sweethearts or lovers, because this undermines the respect they have built up at work.

Gender is toned down. The great majority of women are keen to play down their female attributes.

Loose-fitting clothes and no makeup are standard for many of them offshore – regardless of the type of job they have.

But women in catering do not have the same need to play down their femininity. Because they work in “typical” female occupations, others accept if they act as women.

Women in other roles find it advantageous that somebody else serves as the centre of male attention. Job affiliation appears to be crucial in determining which females are possible objects for chatting up. Those working in catering are considered “worth trying it on with”, while a woman who is seen as one of the “lads” is not perceived as female in the same way.

Female morality debated

Romantic relationships have arisen in the North Sea, as in other workplaces. Some have led to lasting partnerships, while other love affairs have been more transitory.

Informants make such observations as “she was a lady of the more generous type and keen on men”, or “there were some who went right off the rails from all the attention”.

Most of the stories about these transitory romances are characterised by the fact that the discussion concentrates on the woman’s behaviour.

This represents a nature-culture dichotomy, where men are regarded as closer to the culture while women are closer to nature, because female morality becomes the point at issue.[REMOVE]Fotnote: Ortner, Sherry; ed.  Rosaldo, Michelle Zimbalist and Lamphere, Louise; Is Female to Male as Nature is to Culture? Woman, culture, and society Stanford University Press, 1974.

The woman is the one who steps outside the accepted norms, and who can undermine the position of other females by giving their whole gender the stamp of immorality.

Women are felt to have only themselves to blame if they are not properly treated offshore. In other words, a woman who is subject to verbal or other harassment has given the wrong signals and brought it on herself.

Catering workers are often regarded as group which represent a social factor by definition. First, most of the females on a platform are found here, and part of their job is to create homelike conditions for the others.

These personnel are metaphorically the “mothers” in the big platform family..[REMOVE]Fotnote: Solheim, J, og  Hanssen-Bauer, J.   Kompleksitet og fellesskap på en Nordsjø-plattform : rapport fra et besøk på Statfjordfeltet Rapport / Arbeidsforskningsinstituttene, Arbeidspsykologisk institutt, Prosjektgruppe Arbeidsmiljø på kontinentalsokkelen ; 108/83 Oslo : Arbeidsforskningsinstituttene, Arbeidspsykologisk institutt.  They are the ones who create the “domestic” environment with good food and clean, tidy rooms. At the same time, they come into contact with many other occupational groups offshore.

Women in this occupation can allow themselves to categorise males by different criteria than those used by females who work closely with men because they see what lies behind the male facade. Catering gets closer to the private sphere of the other personnel.

Must fit in

Virtually all women employed offshore find it positive to be working in an environment with many men. The attitude is that “if you’re straightforward and genuine yourself, you get a lot back” and “you learn what men are like when you work in a male society”.

The woman is the one who must cope with being in a masculine workplace. “It’s good to have more females, but you must fit it,” is a frequent comment. That refers to succeeding not only in working so intensively, but also in being a woman in a relatively marginal position.

Social relations on land

A factor which is not visible offshore but very definitely present is the relationship with family and friends on land. Most of the women in this study have both husband and children.

Many were mothers when they started working offshore, or have since become so, and have had one or two periods of maternity leave.

Combining a platform job with family life on land is not regarded by the informants as particularly problematic. On the contrary, they have organised themselves in such a way that working offshore and having a good time when at home is preferable to a nine-to-five job ashore.

Some of the mothers have been single parents or shared care with the child’s father. Many have a good network of friends and family who help out when they are offshore. In many cases, it is society at large which makes a problem out of a mother being away from their offspring.

Responsibility for organising matters at home appears to rest with the women. Earlier studies of male offshore workers and feedback from such informants indicate that men employed offshore fail to accept the same level of responsibility for their family.

The helicopter flight from/to land is a key part of working offshore. This journey has been called a rite of passage, but many experience their whole time on the platforms as a marginal phase. You travel from something, spend time away from “normal” society, and reintegrate with it when your tour is over.

A number of North Sea workers start their offshore tour well ahead of flying out. The transition from normal life on land to one directed at their platform job occurs before they depart.

That applies primarily to women. Many of them plan the life of their family while they are away. They organise, clear up and put things in order to minimise the drawbacks for those staying at home. Men are more “a soul and a shirt” when they set off.

   Being visible

Everyone positions themselves and has their standpoint, including those who regard women from the outside and communicate their view. Media want to talk about the North Sea pioneers, labour disputes and special episodes.

The various magazines published by companies say something about their corporate identity: “We support women offshore, and give them opportunities, we want to come across as a company where equal opportunities are important”.

While the positive woman is presented in personal in-depth interviews, however, the negative ones get presented as a group. Females are stigmatised as grumblers and malcontents.

The women worth presenting are the distinctive individuals who become the first to hold a particular job, usually a high-status post previously reserved for men.

Different jobs carry varying weight when describing them. Stories about a hard grind in a tough masculine occupation get more attention than ones on drudgery in the physical care sectors.

Being visible can also be interpreted as others seeing what you do. Many offshore workers find that they are regarded as people who make good money and have a lot of free time – who are better off than others.

Å bli sett kan også tolkes som det at andre ser hva man gjør. Mange som jobber i Nordsjøen erfarer at de blir sett på som personer som tjener godt og har mye fri. De blir sett som folk som har det bedre enn andre.

Neighbours and friends have no idea what happens out in the North Sea, and women working offshore find little understanding in their home environment of what their job is like.

Injection water from subsea installation Ekofisk VC (Victor Charlie) began to be pumped down well VC-03 on 28 September 2018. Well number two came on line just under a week later. 
Kjappe fakta:
  • Plan for development and operation (PDO) was approved by the Ministry of Petroleum and Energy on 7 September 2017.
  • Part of Ekofisk South
  • Installed September 2017
  • On stream September 2018
  • Gets electric power and signals from Ekofisk 2/4 M
  • Also called "Victor Charlie"

The aim of this facility – an extension to the Ekofisk South project – was to increase waterflooding on the southern flank of the Ekofisk reservoir in order to maintain oil and gas production. 

An amended plan for development and operation (PDO) of Ekofisk South was approved by the Ministry of Petroleum and Energy on 7 September 2017. 

This involved installing a new seabed template with four water injection wells, and represented a continuation of the well-established Ekofisk production strategy based on waterflooding.[REMOVE]Fotnote: https://www.regjeringen.no/no/aktuelt/okt-utvinning-pa-ekofiskfeltet/id2570011/. 

The template was installed in September 2017, with a technical solution similar to that used on the seabed facilities already installed – Ekofisk 2/4 VA and 2/4 VB.[REMOVE]Fotnote: Pionér, no 2, ConocoPhillips, 2018.

In addition to the structure itself, including wellheads and Xmas trees, the installation comprised control modules with umbilicals connected to the existing waterflooding system. 

The 2/4 VC facility receives injection water from Eldfisk 2/7 E, while power and control signals come from Ekofisk 2/4 M. It is run from the Ekofisk 2/4 K control room. 

When fully developed, overall injection capacity for this subsea installation will be 80 000 barrels per day through the four wells. 

The water pipeline and umbilical to 2/4 VB were extended to 2/4 VC. Well operations on the latter began on 24 May 2018 with a view to starting injection before the end of the year.

This platform rests on a steel jacket built by Dragados at Cadiz in Spain. The module support frame (MSF) and topsides were fabricated by Energomontaz at Gdansk in Poland and completed at Kværner Egersund. 

The topsides were installed in July 2013. Petroleum and energy minister Tord Lien performed the official inauguration of 2/4 Z and the Ekofisk South project on 29 October 2013,13 just four days after the platform came on stream.14 

No control room is provided on 2/4 Z, but it has a local equipment room (LER) which is not permanently manned. The platform is monitored and remotely controlled from the control room on Ekofisk 2/4 J, but can also be run from the operations centre in Tananger.

 So successful had the 2/4 VA facility proved to be that it was copied for 2/4 VB as an eight-well template, also delivered by FMC at Kongsberg.

Similarly, the wells on 2/4 VB were drilled by Maersk Innovator. The well operation department completed installation of the template, manifolds and casing for the eight subsea wells.

Seabed installations carried out by Subsea 7 comprised a five-kilometre pipeline for water from the Eldfisk Complex as well as a diver-installed T piece welded into the existing pipeline from Eldfisk 2/7 E to Ekofisk 2/4 K.

This assignment also covered laying three kilometres of umbilicals combining hydraulic lines and fibreoptic cables from 2/4 VA, so that 2/4 VB could also be remotely operated from land.

What’s in a name

person By Björn Lindberg
Confusion can easily arise over the terms used in connection with Ekofisk, where the Greater Ekofisk Area (GEA) is a collective designation for a cluster of no less than eight fields. The largest of these is Ekofisk itself.

Kjære barn har samme navn, kart
The Greater Ekofisk Area (GEA) and its constituent fields lie primarily lie in PL 018 (red frame). Those with dotted boundaries have ceased production, while those with lilac borders were producing at 29 August 2019. Note that Valhall and Hod in the south-east corner of the map are not part of the GEA.

Primarily located in production licence PL 018, along with Ekofisk, the other seven fields are West Ekofisk, Tor, Eldfisk, Albuskjell, Edda, Cod and Embla. 

Furthermore, six of the eight – with Embla and Cod as the exception – comprise two geological formations. One is known as the Ekofisk formation, with the Tor formation as the other. See the article on sea scurf. 

The graph in figure 2, which presents collective production of oil, gas and condensate over time in million standard cubic metres of oil equivalent (scm oe), shows Ekofisk’s dominant position – both historically and today.

Kjære barn har samme navn, grav
Historical production from the Ekofisk area since the start of output in 1971 until the end of 2018. The base data were acquired from the norskpetroleum.no website on 29 August 2019.

With the exception of four years, overall output from the seven other fields has never achieved the same volume as Ekofisk’s own production. 

The effect of waterflooding on Ekofisk, which got going seriously in 1987, can be clearly seen in the production curve. This rose from less than 10 million scm oe per annum to more than 20 million. 

On 1 July 2019, operator ConocoPhillips submitted a plan for development and operation (PDO) which covered reopening the Tor field (Tor II). 

This will involve the investment of about NOK 6 billion, with a planned production start in late 2020, and is expected to yield an estimated 10 million scm oe. 

Furthermore, the licensees have initiated concept studies for further development of the northern flank of Eldfisk (Eldfisk II). Both subsea solutions and a simple unmanned platform are under consideration.[REMOVE]Fotnote: https://petro.no/nyheter/conocophillips-vurderer-a-bygge-ny-plattform-pa-eldfisk-nord

Sea scurf – the geology of Ekofisk

person By Björn Lindberg
The oil and gas in Ekofisk lies in a chalk reservoir composed of countless tiny shelly fragments derived from coccolithophores – microscopic algae which make calcium carbonate (CaCO3) scales.

Microscope image from of cookoliths from the Ekofisk reservoir.

Known as coccoliths, these plates are so minute than 30 of them laid side by side would be no wider than a strand of hair. But what they lack in size, they make up for in numbers. 

Their colossal accumulation is helped by the fact that coccolithophores reproduce asexually. When one dies, its coccoliths sinks to the seabed at a rate of about 15 centimetres per day. 

If conditions are right, the scales remain lying and are eventually buried in their billions of billions 

Estimates indicate that coccolithophores globally produce more than 1.5 million tonnes of calcium carbonate per annum – equal to the weight of the Gullfaks C platform, which ranks as the heaviest structure ever moved by humans. 

Three things must be in place for an oil and/or gas field to form – a source rock, a reservoir rock and a cap rock which prevents the petroleum from escaping. 

In the case of Ekofisk, we know quite a bit about how these three components originated. 

Source rock – Draupne

havets flass,

The Ekofisk source rock dates from the Jurassic period, 161-145 million years ago, and comprises organically rich black shales known as the Draupne formation. 

In Norse mythology, Draupne was the gold ring worn by the god Odin which formed another seven rings every ninth day – in other words, an endless source of prosperity. 

So the name is appropriate for a formation found over most of the Norwegian continental shelf (NCS), which has put huge volumes of petroleum into most of Norway’s fields – including Ekofisk. 

Cretaceous reservoir rock – Tor formation

The Cretaceous period followed the Jurassic and lasted for 145-66 million years, with the last 10 million of these forming the Campanian and Maastrichtian stages. 

Conditions then were favourable for coccolithophores over much of the southern and central North Sea as well as England, Denmark and France. 

Countless coccoliths were deposited on the seabed. Since the latter was neither flat nor stable, they were moved around by small slips, landslides and/or mud flows which could be activated by earthquakes, before being finally buried by their successors.

Asteroid

The Cretaceous ended in a mass extinction event, when up to 70 per cent of all life on Earth vanished – including the dinosaurs. 

This wipe-out was unleashed by a massive asteroid strike in what is now the Gulf of Mexico, where the Chicxulub crater is about  150 kilometres in diameter and 20 kilometres deep. The asteroid itself may have measured 80 kilometres.

Palaeocene reservoir rock – Ekofisk formation

That impact nevertheless failed to destroy all marine life, and the “sea scurf” continued to rain down in the following Palaeocene period. 

During its first million years, known as the Danian stage, further tens of metres of calcium carbonate were deposited. But changed seabed conditions and a colder climate had an impact. 

The amount of reworking which the material experienced varied and decreased, while the content of silica derived from microscopic diatoms and radiolarians increased. 

Lower sea levels also meant an increased influx of sediments from land (terrigenous material) in the chalky plates heaping up on the seabed. 

Porosity and permeability

These sediments usually have up to 50 per cent porosity (cavities) when deposited. But this will be considerably reduced by burial and diagenesis (the physical, chemical and biological changes which occur during conversion from sediment to stone). 

In some case, that reduction can be down to well below 10 per cent. However, the good conditions around the Greater Ekofisk Area (GEA) meant that much of the porosity in the chalk was retained.  

It has been calculated at 25-40 per cent. By comparison, a good sandstone reservoir – which is the kind usually found on the NCS – has a porosity of 30 per cent. 

Permeability is also needed to get much oil out of a rock, and the “primary permeability” of Ekofisk chalk is low since the connections between its pores is poor/constricted. 

But the field has enjoyed another stroke of luck here. A large number of fractures in the reservoir have improved its permeability and provide good production properties – at least initially. See water injection. 

Cap rock and trap formation

After the deposition of the Ekofisk formation, conditions changed so that the overlying sediments lost all their porosity when buried and became tight (impermeable). 

That allows them to function as a cap rock which seals the reservoir formed by the Tor and Ekofisk formations. 

The fractures mentioned above were created at the same time as the rocks were subject to movement when large quantities of underlying salt shifted. This also produced large domes and thereby created trap structures where oil and gas can accumulate. 

In other words, the oil migrating from the source rocks has gathered in the reservoir formations under the cap rock – and in amounts which can be difficult to imagine.

The Ekofisk reservoir is as thick as the Eiffel tower is tall and covers an area of 40 square kilometres – the same size as 5 500 football pitches. 

Recoverable oil in Ekofisk totals 3.5 billion barrels, which would be sufficient to supply the whole world with crude for 35 days. 

Roughly 1.1 billion standard cubic metres (scm) of oil (about 6.9 million barrels) and 300 billion scm of gas were present in Ekofisk when production began. 

That corresponds to twice Norway’s annual water production. It also represents more than 100 times annual Norwegian energy consumption and just over 100 days of global oil usage.

It is impossible to get all the oil out of a reservoir, and a distinction is therefore drawn between reserves in place and recoverable reserves. 

However it is measured, though, Ekofisk ranks as one of the very largest fields on the NCS. The original estimate for petroleum recovery from the field was 17 per cent. It is now expected to exceed 50 per cent – in part through waterflooding.

Participants in Ekofisk

person by Kristin Øye Gjerde, Norwegian Petroleum Museum
The question of who “owns” Ekofisk is not straightforward. In simple terms, however, the field and the rest of Norway’s continental shelf (NCS) belongs to the Norwegian state. This was determined on 14 June 1963, when the Storting (parliament) passed the Act Relating to Exploration for and Exploitation of Submarine Natural Resources. This permits licences to be awarded on certain terms.

So it is more appropriate to ask which companies hold and have held rights from the state to explore for and exploit the natural resources in Ekofisk.

More specifically, that relates to interests in production licence (PL) 018. This was awarded in the first licensing round on the NCS in 1965.

The Phillips name has always been included among the licensees. But that is the only constant presence in the list of participants.

This article addresses how the licence composition has altered and how far these changes have been affected by developments in the oil industry generally and on the NCS in particular.

First licensing round, 1965

A single company, A P Møller, was given a sole concession in 1962 to explore for and produce oil on the Danish continental shelf for 50 years.

It is unlikely that anything similar could have happened in Norway, even though America’s Phillips Petroleum Company applied to the Norwegian government in 1962 for a similar licence.

In exchange, it offered to carry out seismic surveys worth NOK 1 million on the NCS. However, consideration of this request was put on hold.

The experience gained by the Norwegian authorities from giving hydropower concessions to domestic and foreign companies since the early 20th century meant nobody was going to get a sole licence.

Instead, the government announced a first licensing round on the NCS on 9 April 1965. The outcome on 17 August was that nine of 11 applicant groups were awarded a total of 74 blocks.

Norwegian industrial interests were then kept at arm’s length from the expensive and risky business of oil exploration, with two exceptions.

One was Norsk Hydro, which participated in the French-led Petronord group, and the other was the Norwegian Oil Consortium (Noco) in the Amoco-Noco team.

The Phillips group comprised the US company (51.74 per cent) with Fina Production Licenses AS (30 per cent) and Norsk Agip (18.26 per cent). It applied for and secured PLs 016, 017 and 018.

Exploring for oil was initially a very uncertain and expensive business. In addition to seismic surveys, the Phillips group had to charter a drilling rig.

That was required for a certain number of wells which the partners were committed to drill under the licence terms. They also had to pay the government an annual fee of NOK 50 000.

But the group had little idea that it had hit the jackpot. PL 018 covered blocks 1/5, where nothing has admittedly been found, 2/4 containing Ekofisk, 2/7 with Eldfisk, and 7/11 holding Cod.

A production licence on the NCS gives its holders the exclusive right to conduct exploration drilling for and production of petroleum deposits within a specified area. A production licence on the NCS gives its holders the exclusive right to conduct exploration drilling for and production of petroleum deposits within a specified area. Such licences are awarded by the Ministry of Petroleum and Energy to sets of licensees. These are comprise oil companies, with one designated as the operator to conduct operations on behalf of each group. Each licensee owns its proportionate share of the petroleum produced from the licence area. If a commercial discovery is made in the licence area, it can be developed by the licensees. This must be done on the basis of an approved plan for development and operation (PDO), which has been drawn up in accordance with the provisions of Norway’s Petroleum Act. Oil and gas which have not been produced remain the property of the Norwegian state.

Enter Petronord

The Phillips group pursued talks in 1967 with the Petronord group on a closer collaboration aimed at spreading risk more widely on the NCS.

These negotiation were initiated after other companies had drilled dry wells and spent a lot of money without seeming to have anything to show for it.

The outcome in 1968 was a swap of licence interests – a fairly common practice in the international oil industry. Phillips and Agip transferred 20 per cent of their holdings to Petronord in exchange for a similar proportion of the latter’s licences.

At the same time, agreement was reached that the two groups would share the cost of the Ocean Viking drilling rig and use it turn and turn about.

This brought a number of new licensees to PL 018 – Elf Norge AS (7.1 per cent), Total Norge (5.325 per cent), Aquitaine Norge AS (3.55 per cent) and Norsk Hydro Produksjon AS (2.5 per cent).

In addition, the minor French companies Eurafrep Norge AS, Coparex Norge AS and Cofranord AS each held a tiny fraction.

Fina retained 30 per cent, while Phillips reduced its share from 51.74 per cent to 36.96 per cent and Norsk Agip was cut from 18.26 to 13.04 per cent.

Rumours of a big discovery began to circulate in the autumn of 1969, with 25 October taken as the date when the geologists were sure a major find had been made in block 2/4. But Phillips did not officially report it to the government until 23 December.

This success was a good start for everyone who now held a stake in the licence, including Hydro. However, the interests Petronord passed to the Phillips group never yielded anything – which nobody could have predicted when the swap was made.

A press release on the Ekofisk discovery was finally issued on 2 June 1970. Meanwhile, the Norwegian government was seeking to secure a stronger involvement in NCS operations.

In deepest secrecy, the government bought up shares in Hydro on 9-15 December 1970 which ensured a majority state holding in the company.

This acquisition was officially approved by the Council of State on 22 January 1971, and gave the state a small stake in Ekofisk.[REMOVE]Fotnote: Hanisch, Tore Jørgen and Nerheim, Gunnar, Fra vantro til overmot?, Norsk oljehistorie, volume 1, Oslo, 1992: 165-166.

The Petronord deal had given Hydro an option to acquire 12 or 24 per cent of the group’s interest in a discovery.[REMOVE]Fotnote: Ibid. Holdings in PL 018 were therefore redivided again on 1 January 1971.

While the Phillips group retained its previous shares, Norsk Hydro Produksjon AS purchased interests from its Petronord partners which left it with 6.7 per cent of PL 018.[REMOVE]Fotnote: Elf Norge AS went down to 5.396 per cent, Total Norge to 4.047 per cent, Aquitaine Norge AS to 2.698 per cent, Eurafrep Norge AS to 0.456 per cent, Coparex Norge AS to 0.399 per cent and Cofranord AS to 0.304 per cent.

The next change in licensee composition occurred on 1 July 1977, when Elf and Aquitaine merged to form Elf Aquitaine Norge AS and thereby had an 8.094 per cent holding.

Statoil in and out

After the creation of Statoil in 1972, Norway’s state oil company built up a dominant position on the NCS with the right to a 50 per cent interest in new licences.

But many years were to pass before it secured a foothold in PL 018. That did not occur until 1988, when both international politics and major economic interests were involved.

The Troll gas sales agreement with a European consortium was the spark. Swapping licence interests between Statoil and France’s Elf and Total could provide the basis for this deal.

Estimated to contain 60 per cent of Norway’s gas reserves, Troll was proven in 1981 and declared commercial two years later. Nailbiting sales talks with continental gas buyers in 1985 were essential for developing the field.

These negotiations made slow progress, with the French particularly lukewarm. Something had to be done to persuade them to take a more positive view.

Elf and Total wanted licence interests in Troll and the Sleipner gas field. Could that be achieved, it might make the authorities in France more receptive to an agreement.

Statoil was therefore ready to enter into a swap which gave the French companies holdings in the two gas fields in exchange for a one per cent stake in Ekofisk.

Since it was difficult to estimate the value of this exchange, a net profit deal was also agreed – if revenues from one field exceeded a set value, the other party would be compensated.

The NOK 800 billion Troll gas sales agreement was entered into in May 1986, with the swap of licence interests coming into force on 1 April 1988.

This deal was considered important for securing French government approval of the sales agreement with Gaz de France, which was needed for a Troll go-ahead.[REMOVE]Fotnote: Reported by Ole-Johan Lydersen, a participant in negotiating the agreement, on 20 August 2019.

The advantage for Statoil of securing an interest in Ekofisk was the right this conferred to attend management committee meetings, providing it better insight into licence developments.

It gave the company control over the whole transport chain for gas exports, something which had concerned it ever since the Norpipe link from Ekofisk to Emden was installed in the 1970s.

During the 1980s, the Ekofisk Complex represented an important hub for Norwegian gas exports. The Ekofisk 2/4 S riser platform, operational from 1985, tied the Statoil-operated Statpipe transport system into Norpipe.

This installation was owned by Statoil but operated by Phillips. In 1998, the Statpipe-Norpipe line was relaid to bypass the Ekofisk Complex.

Another but less important reason why the state oil company wanted to know what was going on in PL 018 was the relationship between Tommeliten and Edda.

The former was a condensate field operated by Statoil which produced to the Phillips-operated Edda oil and gas field 12 kilometres away.

Following the oil price slump in 1985-86, Phillips – which had a 25 per cent interest in Tommeliten – became sceptical about developing it and withdrew from the project.

Statoil nevertheless secured acceptance in 1986 for a cheaper development solution based on subsea templates – which gave it useful experience with underwater technology.

Although Phillips had pulled out, it still wanted the Tommeliten wellstream to flow to Edda – not least because this field had proved half the size originally estimated.

That provided spare gas processing capacity. Moreover, the Tommeliten gas could be injected into the Edda reservoir to increase oil production.

The tie-in to Edda was implemented. According to Statoil, however, negotiating tariff terms between the Tommeliten and Ekofisk licences proved difficult.[REMOVE]Fotnote: Reported by Håkon Lavik, 15 August 2019.

Statoil’s interest in PL 018 changed again on 1 January 1999, when the government secured a five per cent stake for the state’s direct financial interest (SDFI) on the NCS.

Part of the Ekofisk II agreement with the Phillips group, this gave Statoil 5.95 per cent[REMOVE]Fotnote: Norwegian Petroleum Directorate, Facts, 2000. and resulted in a corresponding reduction in the holdings of the other licensees.

For the first time since 1968, Phillips saw its share of the licence reduced – but only from 36.96 per cent to 35.112 per cent.

Several reforms related to Norwegian state ownership in the petroleum sector were under way at this time. Plans for part-privatising Statoil to achieve greater flexibility internationally were initiated in 1999 and approved in 2001.

Another change was that administration of the SDFI, which had lain with the state company since 1985, was transferred in 2001 to a separate company called Petoro.

The latter took over various Statoil holdings in fields. Where the Greater Ekofisk Area was concerned, it acquired five per cent in PL 018 on 10 May 2001. That left Statoil with 0.95 per cent.

Total becomes biggest licensee

Crude prices slumped to a record low at the end of the 1990s, leaving the oil companies with acute profitability problems. They responded with mass redundancies and restructurings.

Larger entities provided greater strength in the market, improved cost control and better positioning in relation to the competition for reserves.

The turmoil which followed in the wake of these restructurings also affected the purchase and sale of interests in the Ekofisk licence.

Saga Petroleum, which acquired Norminol’s holding on 1 January 1995, disappeared on 11 January 2001. Its stake was taken over by Norsk Hydro Produksjon, which thereby rose to 6.654 per cent.

The French interests were gradually consolidated, with Eurafrep, Coparex and Cofranord being acquired in 1990 by Elf Rep, Elf Rex and Norminol respectively.

Elf Rep and Elf Rex then merged in the summer of 1992, and this company was incorporated in 1997 in Elf Petroleum – which thereby acquired 8.449 per cent of PL 018. Elf was merged into TotalFinaElf in the summer of 2000.

Just before Christmas that year, Total and Fina’s licence interests were merged with Total Norge’s holdings and thereby amounted to 31.87 per cent.

When these shares were then incorporated with TotalFinaElf’s, the result was a combined holding of 39.896 per cent. From 6 May 2003, TotalFinaElf was renamed Total E&P Norge AS.

This company then ranked as the largest licensee in PL 018, with the operator – now ConocoPhillips Skandinavia AS following the 2002 merger – in second place with 35.112 per cent.

Since Conoco had no stake in Ekofisk from before, its union with Phillips Petroleum did not contribute to increasing the company’s combined holding.

In addition, Italy’s Eni Norge AS took over Agip’s interests in the Greater Ekofisk Area on 15 December 2003.

Statoil merges with Hydro

After Petoro had acquired the bulk of Statoil’s interest in PL 018, a new change occurred in 2007 when the state company merged with Hydro’s petroleum and energy division.

From 1 October that year, StatoilHydro ASA held 0.95 per cent of the licence while StatoilHydro Petroleum had a 6.654 per cent interest.

These holdings were combined from 1 January 2009 into a 7.604 per cent stake held by StatoilHydro Petroleum AS. The company was renamed Statoil Petroleum AS on 2 November 2009.

The final change of name for this licensee occurred on 16 May 2018, when Statoil became Equinor. This was intended to signal that it embraced not only fossil fuels but also renewable energy sources such as solar and wind power.

A similar concept underlies the new company formed on 10 December 2018 by Eni Norge and Point Resources under the name Vår Energi AS.

“Vår” has a double meaning in Norwegian, denoting not only “Our Energy” but also springtime as a season of youth, freshness and greening.

Licence interest in 2019

On the 50th anniversary of the Ekofisk discovery in 2019, ConocoPhillips Skandinavia is operator for the field with a 35.11 per cent holding.

The other licensees at this time are Total E&P Norge AS (39.90 per cent), Vår Energi AS (12.39 per cent), Equinor Energy AS (7.60 per cent) and Petoro AS (five per cent).[REMOVE]Fotnote: Norwegian Petroleum Directorate fact pages, 13 August 2019.

Knut Åm – oil and gas veteran

person by Kristin Øye Gjerde, Norwegian Petroleum Museum
The special contribution made by Knut Åm to Phillips Petroleum Company was one reason for his appointment in 2014 as a Knight First Class of the Royal Norwegian Order of St Olav.

Åm was born at Årdal in the Sogn district of western Norway in 1944, and grew up in Oppdal and Volda/Ørsta where he proved an able pupil at school. 

He opted to study mining engineering at the Norwegian Institute of Technology (NTH) in Trondheim, graduating with honours in 1967. 

Åm’s first job was with the Norwegian Geological Survey (NGU), again in Trondheim, where he worked and conducted research for six years. One of his jobs was to interpret aeromagnetic measurements of sub-surface rocks made from the air, which provide valuable information on geology and prospects for finding petroleum. In a series of publications, he described the big sedimentary basins identified in the Skagerrak between Norway and Denmark and in the Norwegian and Barents Seas. 

He joined the Norwegian Petroleum Directorate (NPD) in 1974, serving as a section head in the resource department and a principal engineer in the safety department. 

That was followed by three years with Statoil, where he became the state oil company’s first vice president for research and development. His appointments at the time included chairing a research programme on offshore safety, which led to legislation enacted by the Storting (parliament) and a bigger research effort. 

Joining Phillips

Åm secured a job with Phillips in 1982 and was soon sent to the head office at Bartlesville in Oklahoma to get better acquainted with the company and its corporate culture. 

After a year in the USA, he returned to the company’s Tananger office outside Stavanger and became the first Norwegian to serve as offshore manager for the Greater Ekofisk Area (GEA). 

That put him in charge of 23 platforms, with responsibility for the waterflooding programme as well as the project to jack up a number of the installations. These major developments extended the producing life of the GEA and sharply increased estimates for recoverable reserves from its fields. 

Åm led this work during difficult times, with low oil prices and the need to implement cost savings and overcome substantial financial challenges. As if that were not enough, he also taught at the University of Bergen from 1985 to 1990 as an adjunct (part-time) professor of applied geophysics.

After heading operations in the Permian and San Juan Basins at Odessa, Texas, from 1988-91, Åm became the first Norwegian president and managing director for Phillips Petroleum Norway. 

That put him in charge of 3 000 employees in the GEA as well as in Tananger, Oslo, Teesside and Emden. This was when a redevelopment of Ekofisk was planned, along with the future cessation and removal of old platforms.[REMOVE]Fotnote: https://www.fylkesmannen.no/globalassets/fm-rogaland/dokument-fmro/felles-og-leiing/brev-og-artiklar/fm-tale-til-knut-am.pdf 

By 1996, Åm was back in Bartlesville – now as vice president and head of all exploration and production in Phillips. He stayed in that job until retiring in the USA during 1999.

Offices and committees

But his working life did not end there. Appointments from 1999 to 2007 include membership of the Statoil board – and many similar posts can be mentioned. 

Åm has been president of the Norwegian Geological Council and the Norwegian Petroleum Society, and chair of the Norwegian Oil Industry Association (now the Norwegian Oil and Gas Association). 

He led the exhibition committee of the 1996 ONS oil show in Stavanger, and has chaired Bergen’s Christian Michelsen Research institute as well as the industrial council of the Norwegian Academy of Science and Letters.  

In addition to chairing Hitec ASA, he has been a director of several technology companies. 

Mention must also be made of the improved recovery committee appointed by the Ministry of Petroleum and Energy with Åm as chair. This produced a report in September 2010 which presented 44 specific measures for improving the recovery factor on the Norwegian continental shelf (NCS). 

Through his work and many appointments, Åm has been acclaimed for a combination of expertise, creativity and determination.  He also demonstrated the ability to tackle the requirements of Norway as a nation as well as the industry and its employees – not least with regard to the working environment and safety in a demanding and risky offshore industry. 

Optimist

In retirement, Åm is an optimist – with regard to the climate as well. “I’m very concerned with nature, but believe we should extract the resources its given us,” he told Otium in 2016. 

“Norway could have a long and good future in the oil and gas industry if people give it more support. Exploring for new deposits is important, but we should also seek to achieve a far better recovery factor from both new and existing fields.” 

“You can naturally concentrate on life’s negative aspects. Then everything’s simply awful. I think you’ll be a far happier person if you prefer to see the positive side of life. I call that self-motivation. We need more of that in the energy sector.”[REMOVE]Fotnote: https://api.optimum.no/sites/default/files/PDF/optimum-magasinet-2016.pdf

Getting the timing right

person by Trude Meland, Norwegian Petroleum Museum
The issue of work schedules for offshore personnel has been subject to constant discussion between government, employers and unions – leading to radical changes over 50 years.

Different systems for rotating personnel between work and leisure functioned in parallel on the drilling rigs during the early years of oil exploration in the Norwegian North Sea. The most common practice was nevertheless one week on and one off. To get a holiday, people carried on working offshore until they were entitled to three weeks free in one go.

However, this arrangement proved impractical – particularly for workers who going offshore or returning home on a Saturday or Sunday. They never got a full weekend off. To stagger such change-overs, the schedule was extended to eight days offshore with eight days free. One work period in five was also dropped, so every fifth free spell was 24 days long.[REMOVE]Fotnote: This gave a working time which averaged 38 hours per week and 1 824 hours per year after holidays. That corresponded to shift work on land.

When Norway’s Working Environment Act (WEA) came into force in 1977, the permitted length of a continuous shift on land was cut. But there was no assurance that this would be applied offshore. In its original form, the Act did not permit the 12-hour working day normal on all offshore installations. So amendments were needed to adapt the legal provisions to fixed platforms.[REMOVE]Fotnote: The Act specified that working time was 36 hours over seven days for work carried out around the clock throughout the week. That represented 1 877 hours a year on average. Adjusting this for four weeks of holiday gave a net working time of 1 733 hours.

The Norwegian Petroleum Directorate argued that reducing working time offshore was impractical, with the “special character” of the oil industry requiring exemptions.[REMOVE]Fotnote: Ryggvik, H, 1999, “Fra forbilde til sikkerhetssystem i forvitring: Fremveksten av et norsk sikkerhetsregime i lys av utviklingen på britisk sokkel”, Working Paper, Volume 114, Centre for Technology and Culture, University of Oslo, printed edition. Oslo: Centre for Technology, Innovation and Culture (TIK), University of Oslo: 16. As early as 1975, however, Ekofisk operator Phillips Petroleum had agreed to working hours for its own personnel which accorded with the provisions proposed for the new Act. A royal decree of 9 July 1976 extended the existing Worker Protection Act, with certain exceptions, to the fixed installations offshore on a temporary basis.

The WEA was then applied to these facility in 1977.[REMOVE]Fotnote: Ryggvik, H, 1999, “Fra forbilde til sikkerhetssystem i forvitring: Fremveksten av et norsk sikkerhetsregime i lys av utviklingen på britisk sokkel”, Working Paper, Volume 114, Centre for Technology and Culture, University of Oslo, printed edition. Oslo: Centre for Technology, Innovation and Culture (TIK), University of Oslo: 18. This meant that offshore workers had their working time regulated and acquired legal safeguards against unfair dismissal. After long discussions, the North Sea schedule was by and large established as two weeks working offshore and three weeks free on land.

But the WEA was not applied to floating units such as rigs, and working time in that part of the oil industry continued to be regulated by Norway’s Ship Labour Act.

 An extra day

Norway’s legislation on paid holidays was amended in 1981 to give everyone a legal right to four weeks and one day off. The latter was nicknamed the “Gro Day” after Gro Harlem Brundtland, the Labour premier of the day. This meant the two weeks on/three weeks off schedule now imposed too many working hours. It was decided that the extra would be compensated as 25 hours of overtime per year.[REMOVE]Fotnote: Working time was reduced from 1 752 to 1 727 hours.

Agreement was reached in the 1986 collective pay negotiations on a 7.5-hour normal working day and a 37.5-hour week. Personnel both on land and offshore working a continuous shift also had their weekly hours cut 33.6.[REMOVE]Fotnote: Net working hours after deducting holidays were reduced from 1 752 to 1 727. To comply with these new terms, the offshore schedule was altered to two weeks at work, three weeks ashore, two weeks at work and four weeks on land.

When the Gro Day was introduced in 1981, the Labour government originally proposed introducing a full week’s extra holiday in stages over three years. But that failed to materialise. In 2000, the Norwegian Confederation of Trade Unions (LO) proposed a fifth holiday week for all employees, which would thereby reduce the number of hours in a work-year.[REMOVE]Fotnote: That involved an additional four free days of 7.5 hours offshore (32 hours). The hours to be worked were then reduced from 1 612 to 1 580. That demand was accepted, and most workers could thereby enjoy five weeks off. This naturally had consequences offshore, but implementing it there was not a straightforward matter.

A schedule of two weeks at work and three/four weeks at home had been 19 hours short of a normal work-year. That was overcome by deducting this time from pay or leaving the first 11 hours of overtime unpaid.[REMOVE]Fotnote: Sande, Leif, “Arbeidstiden på sokkelen”, Sysla – meninger, 11 March 2015.

The new holiday deal meant that an offshore worker would be doing 12 extra hours per year. This was initially paid as overtime, which the unions found unsatisfactory. They demanded the full holiday entitlement awarded to everyone else through the introduction of a schedule of two weeks on and four off. In 2002, the Norwegian Oil Industry Association (OLF – today the Norwegian Oil and Gas Association) allowed local deals under the offshore agreements to adopt this two-four scheme. All the companies subject to these agreements introduced the new schedule. ConocoPhillips was among the operators to do this, in its case covering the Greater Ekofisk Area.

However, the two-four system meant workers were falling short of a work-year by 122 hours.[REMOVE]Fotnote: Working 12 hours a day for 14 days, followed by four weeks off, means that an employee works 168 hours every six-week period. That adds up to 1 460 hours per year. Annual pay was thereby cut by 7.71 per cent to take account of the reduced time worked.[REMOVE]Fotnote: Norwegian Official Reports (NOU) 2016:1, Arbeidstidsutvalget — Regulering av arbeidstid – vern og fleksibilitet. https://www.regjeringen.no/no/dokumenter/nou-2016-1/id2467468/sec16. Other conditions were also set on Ekofisk. The whole offshore organisation was to be reviewed to find efficiency gains, and the agreement specified that the change would not lead to an increase in the workforce.[REMOVE]Fotnote: Pioner, “2-4-ordningen innføres”, March 2003.
