HOUSTON, July 6
– Perenco, Paris, encountered a petroleum system and multiple viable reservoirs but subcommercial quantities of natural gas at the N’gata-1 exploratory well on the Kombe-N’sepe block in the Douala basin onshore Cameroon.

Kosmos Energy Co., which has a 35% interest in the block, said the results of drilling, wireline logs, and reservoir fluid samples show the well penetrated 144 ft of reservoir with 33 ft of net gas-bearing pay. An additional deeper thick sand interval with gas shows was encountered, but complete wireline logs could not be obtained over this target due to operational difficulties. The well has been plugged and abandoned.

Kosmos has now completed its initial drilling program commitment on the block. Future technical evaluation will focus on identifying the positive play elements in areas of the block where liquid content and trap effectiveness may improve. Perenco operates the block with 40% interest, and Cameroon’s Soc. Nationale des Hydrocarbures has 25%.
