Maersk Oil has discovered gas in appraisal well 22 / 25a-10z in the high pressure high temperature (HPHT) Culzean discovery in the North Sea.

The well was drilled in the UK sector of the Central North Sea, about 145km east of Aberdeen, to verify the extension of the original Culzean well, which was discovered in 2008.

The well encountered gas and condensate at an average depth of 4.5km in the target Triassic and Jurassic-age reservoirs.

During tests in two intervals, well 22 / 25a-10z delivered 40 million cubic feet of gas and 900 barrels of condensate per day in each interval.

Maersk Oil UK managing director Martin Rune Pedersen said the production test shows that the Culzean discovery has the potential to be one of the most promising HPHT discoveries in the UK sector in recent years.

“Culzean will be a key project in Maersk Oil’s long-term growth plan for its UK activities,” said Pedersen.

Maersk Oil holds a 49% interest in Culzean as its operator and is partnered by JX Nippon UK with 17%, Eni UK with 16.95% and BP with 16%.
