PROJECT DESCRIPTION

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.

SOUTHERN NORTH SEA

OPERATOR:

DANA PETROLEUM (E&P) LTD


PROJECT DESCRIPTION

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 were 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.

Currently the Joint Venture are planning on a Final Investment Decision for the development of the Platypus Field, later in 2019.

SKERRYVORE “LICENSE P. 2400 (Blocks 30/12c, 30/13c, 30/17h & 30/18c) & License P. 2402 (Block 30/19c)”

PARKMEAD (E&P) LTD


PROJECT DESCRIPTION

Blocks 30/12c, 13c, 17h and 18c are situated in the prolific Central Graben of North Sea. Four play fairways are developed on this acreage providing six prospects. Significant prospectivity has been mapped at Palaeocene Mey Sandstone and Cretaceous Chalk level, with additional prospectivity recognised within the deeper Jurassic Fulmar play. The Palaeocene Mey and Chalk are proven productive reservoirs in the area by fields and discoveries such as Joanne, Judy, Orion and Flyndre.

 The Skerryvore Mey prospect overlies two stacked Chalk prospects (Skerryvore Ekofisk and Skerryvore Tor) which are associated with a Zechstein salt diapir called Skerryvore. The Chalk in these prospects is thought to have been re-worked, which significantly improves permeability over conventional Chalk reservoirs. These three stacked prospects have the potential to contain 157 million barrels of recoverable oil equivalent on a P50 basis. An additional Paleocene Mey prospect (Skerryvore West) and one Chalk prospect (Skerryvore North) are also identified on the blocks. The proposed work programme includes purchasing  and reprocessing 3D seismic, carrying out rock physics work and a contingent well. 

Block 30/19c lies immediately to the east of the Skerryvore blocks near the UK-Norway median line and contains Ruvaal, a Palaeocene Mey combination structural and stratigraphic trap. The work programme includes a drill or drop well.

These licenses were awarded in 2018 as a part of 30th offshore licensing round in UK.
