Ekofisk 2/4 VC

person Norwegian Petroleum Museum
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.
