Maersk Oil has confirmed significant volumes of gas and condensate with an appraisal well drilled on its Culzean high-pressure/high-temperature (HPHT) discovery in the UK North Sea, verifying an earlier Upstream report.

The 22/25a-10z probe was drilled in the central North Sea to verify an extension of the original Culzean discovery well in 2008 and confirmed the presence of a significant hydrocarbon accumulation, the Danish operator said.

Gas and condensate was confirmed at an average depth of about 4.5 kilometres in Triassic and Jurassic reservoirs.

The well was tested in two intervals and delivered a rig constrained rate of nearly 40 million cubic feet of gas and 900 barrels per day of condensate in each interval.

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

Maersk and its partners are now planning a further appraisal programme that includes a sidetrack well down flank to the east of the appraisal well to assess the full extent of the field. The results of this sidetrack well are expected this summer , after which a further appraisal well will be drilled.

Maersk is the operator with a 49.99% interest in Culzean, with partners JX Nippon UK (17.06%) Eni UK (16.95%) and BP (16%).
