SOUTHERN NORTH SEA
CONOCOPHILLIPS (U.K.) LIMITED
The Victor Gas Field is located in the Southern North Sea and has estimated remaining reserves of less than 1 billion cubic feet net to CalEnergy. An unmanned platform is installed at the field which produces from five production wells and a sixth subsea well, which is tied back to the platform. The gas is transported through a 16-inch pipeline to the Viking Field and then onto the Theddlethorpe shore terminal. The field has been in production since September 1984. CalEnergy markets its own share of gas production from the Victor Gas Field.
The Victor field ceased production in early 2016. The decommissioning programme is currently being undertaken.

DANA PETROLEUM (E&P) LTD
In 2005, CalEnergy successfully applied for Block 48/1a in the United Kingdom North Sea’s Southern Gas Basin. Adjacent Blocks 48/1c and 47/5b have been subsequently secured.
CalEnergy entered into an arrangement with Dana Petroleum plc, under which Dana assumed the operatorship of Block 48/1a, and CalEnergy’s interest in Block 48/1a was reduced to 15 percent. The 48/1a-5 Platypus discovery well, spudded on March 3, 2010, was drilled to a total measured depth of 11,048 feet encountering some 218 vertical feet of porous gas bearing sands. The well was suspended for potential re-entry and future use as a gas production well on May 4, 2010. It was reported by Dana Petroleum plc that preliminary analyses indicate that the reserves discovered were in line with predrill estimates of approximately 130 Bcf of gas and it was a significant gas discovery for the United Kingdom’s Southern North Sea.
Appraisal well 48/1a-6 was spudded on April 11, 2012, with the Ensco 80 jack up drilling rig. The well reached a total measured depth of 14,175 feet on June 19, 2012, having successfully drilled a 3,100 foot horizontal section within the reservoir. The well, which recorded a test flow rate of 27 MMscf per day on a 96/64” choke, was successfully suspended for use as a future production well on August 7, 2012.
The Joint Venture are now analyzing the development options.
