The Ithaca Energy-led joint venture sanctioned the well in order to increase reservoir pressure and maximize recovery from the field. Later this year a new subsea pipeline will be installed linking the well to the FPSO Anasuria.
Cook P1, the field’s existing production well, has delivered more than 50 MMbbl of oil since start-up in 2000.
During drilling of the latest well, reservoir pressure at the injection location was in line with predictions and the well will now be completed to provide pressure support to Cook P1.
The oil-water contact is deeper than originally anticipated. Although the implications of this may be positive, further analysis is needed before the group can assess the field’s remaining reserves, Hibiscus said.
Cook is one of four producing fields in the Anasuria Cluster originally developed by Shell.
Ping Petroleum UK is the other partner in the current joint venture.
