LONDON, Nov. 18 -- Sterling Resources Ltd. will suspend well 210/29a-4 in the UK northern North Sea to evaluate the size and development options of an oil discovery on the Bowstring East prospect.

The Cladhan well encountered an oil column of more than 110 ft, with no observed oil-water contact, in an Upper Jurassic sequence below 9,450 ft. It contained 25 ft of sandstones with log porosity exceeding 20% and showed high oil saturations.

The well, drilled on Block 210/29a, is in license P1064. Transocean's 704 semisubmersible rig targeted a seismic amplitude-driven Upper Jurassic anomaly down-dip and eastward of the East Shetland platform. The well was in 535 ft of water and reached a total measured depth of 9,735 ft.

"Although the well will not be flow-tested, an extensive pressure test measurement program and the collection of oil samples through a modular formation tester logging tool, suggest good reservoir mobility and therefore promising productive potential," Sterling said.

David Findlater, Sterling's vice-president for exploration, said, "This wildcat well has met all expectations and confirmed the presence of a hydrocarbon bearing stratigraphic trap. Our immediate plan is to integrate the well results with the seismic data and to determine the size of the oil accumulation before submitting our appraisal strategy."

Sterling secured the acreage in 2003 under the Promote Licensing Round in the 21st UK Offshore Round.

Sterling, which has a 39.9% interest, has partners in the license: Revus Energy (UK North Sea) Ltd. 33.5%, Encore Petroleum Ltd. 16.6%, and Dyas (UK) Ltd. 10%.
