Cameroon

HOUSTON, Jan. 21 -- BowLeven PLC, Edinburgh, plans further appraisal drilling on the Isongo-E and F structures on the MLHP-7 block of the 2,314 sq km Etinde permit off northern Cameroon.

The Isongo-F-1r exploration well averaged 3,371 b/d of oil on a ½-in. choke and peaked at more than 4,000 b/d with a GOR of 1,200 scf/bbl from the uppermost Miocene Isongo formation below 5,750 ft MD in 2008. Analysis indicated 137 million bbl of oil in place.

The structure continues south, and the mean initial estimate for its untested southern compartment is 142 million bbl in place.

BowLeven said the discovery "transformed the traditional perception and understanding of Cameroon's petroleum systems, which ascribed oil potential only to the northern part of the Rio del Rey basin with all acreage south of this historically considered to be gas and gas-condensate prone."
