Total announced a new significant discovery in the North Sea offshore U.K., on the Glengorm prospect located in the Central Graben.
The well was drilled to a final depth of 5,056 meters and encountered 37 meters net gas and condensate pay in a high quality Upper Jurassic reservoir with excellent properties. Recoverable resources are estimated close to 250 million barrels of oil equivalent. Further drilling and testing will be carried out to appraise resources and the productivity of the reservoir, Total, which holds a 25 per cent interest in the discovery, said. CNOOC Petroleum Europe, a subsidiary of CNOOC Limited hold 50 per cent interest and operatorship, while Euroil, a unit of Edison E&P owns 25 per cent.
“Following the recent Glendronach discovery, West of Shetland in the U.K., Glengorm is another great success for Total in the North Sea, with results at the top end of expectations and a high condensate yield in addition to the gas,” said Kevin McLachlan, senior vice president exploration at Total.
“Our strong position in the region will enable us to leverage existing infrastructures nearby and optimise the development of this discovery. Glengorm is an achievement that demonstrates our capacity to create value in a mature environment thanks to our in-depth understanding of the basin.”
The discovery is located on the P2215 license, which was previously part of the Maersk Oil portfolio, in water depth of about 80 meters, close to existing infrastructures operated by Total and offering tie-back possibilities, such as the Elgin-Franklin platform and the Culzean project, scheduled to start production this year. It also presents some upside potential with several other prospects already identified on the same block.

“At 250 million barrels of oil equivalent (boe), CNOOC Ltd’s Glengorm is the largest gas discovery in the UK since Culzean in 2008,” Kevin Swann, a senior analyst with Wood Mackenzie’s North Sea upstream team, said after CNOOC and its partner Total announced the discovery.
Mr Swann added: “There is a lot of hype around frontier areas like West of Shetland, where Total discovered the Glendronach field last year. But Glengorm is in in the Central North Sea and this find shows there is still life in some of the more mature UK waters.”
