HOUSTON, July 1 -- Although not quantified, the Moth exploration well in UK Central North Sea Block 32/21 is a large discovery, said the UK subsidiary of Oilexco Inc., Calgary.

The 23/21-6z Moth discovery well went to TD 14,616 ft and cut 605 ft of hydrocarbon-bearing sands in Middle Jurassic Pentland and 219 ft in Upper Jurassic Fulmar, Oilexco said. The company earned a 50% working interest at Moth, where its partners are BG Group, Hess Corp., and BP PLC.

A packer failure prevented flow measurement on a drillstem test of Pentland perforations at 13,276-730 ft in 439 ft of oil and gas bearing reservoir sands. Further tests are likely in a future appraisal well.

The primary target Fulmar sands at 12,982 ft are to be perforated later in July at 12,980-13,030 ft for tests in 118 ft of gas-condensate bearing reservoir sands.

Appraisal wells will likely use higher-capacity test equipment, Oilexco said. Moth is just south of Lomond gas field.
