ABERDEEN, UK --Oilexco has discovered oil with a well on the Kildare prospect in UK central North Sea block 15/26b. Well 15/26b-9 was drilled to a total depth of 4,367 m (14,330 ft), and penetrated 27.74 m (91 ft) of net pay from a 40.23 m (132 ft) gross section within Upper Jurassic sand.

Well logs and wireline pressure measurements suggested that the entire Upper Jurassic reservoir sand was oil-bearing. A drill-stem test of a 38 m (125 ft) interval flowed 4,216b/d of oil and 944,880 cm/d (3.1 MMcf/d) of gas through a 64/64-in. choke, with a flowing tubing pressure of 460 psia.

Oilexco and its partner Nexen Petroleum aim to return to Kildare for further appraisal wells to determine the extent of the oil accumulation. Recovered oil samples suggest a link with the oil-bearing sand discovered by a previous operator in the block in 1988, at a location 2 km (1.24 mi) north of 15/26b-9.
