HOUSTON, Feb. 16 - Appraisal wells on Ledjmet Block 405b in the Berkine basin discovered a new pay zone of Middle Triassic age and indicated extension of several pools in Menzel Ledjmet East gas-condensate field, said First Calgary Petroleums Ltd., Calgary.
The LES-2 appraisal well gauged 12.2 MMcfd of gas and 2,494 b/d of condensate from Lower Siegenian (Devonian) F6-2A, 9.9 MMcfd and 1,601 b/d from Middle Siegenian F6-2A, 7.1 MMcfd and 2,090 b/d from Lower Triassic TAGI, and 5.7 MMcfd and 1,377 b/d from Upper Triassic TAGI.
The new zone, Triassic TAGM, flowed 7.2 MMcfd and 1,754 b/d and "is now recognized by FCP as a new play fairway extending across much of the southwestern portion of Block 405b," the company said.
Normalized to 2,000 psi flowing wellhead pressure, the well's five zones are capable of 91.8 MMcfd and 18,357 b/d, the company said. The reservoirs are at 3,180-4,500 m.
Logs at the MLE-6, at 7.4 km southwest of the discovery well the field's most westerly and downdip well, indicated 46 m of net hydrocarbon pay in multiple geological intervals.
FCP has been appraising Sonatrach's MLE discovery since early 2003. Production is to start in 2007.
