Operational update - IE-2 well test results


Further to the announcement of 19 February 2007, BowLeven is pleased to announce
that the IE-2 appraisal well, drilled in the E Field, Block MLHP 7 of the Etinde
Permit in Cameroon, has successfully tested gas and condensate from the Isongo
formation. The well flowed at a stabilised rate of 30 mmscfd and 3800 bpd
through a 60/64 inch choke with a flowing well head pressure of 2126 psi. The
rate of flow was constrained due to the capacity of the test equipment.

The well will now be suspended as a possible future producer. The Adriatic VI
drilling rig will then be moved a short distance to Block 5 of the Etinde Permit
to drill a higher risk exploration prospect in the sparsely explored Douala
Basin.

Following this second well it is likely that the rig will return to Block 7 and
drill an exploration prospect which is located up dip from the adjacent E Field.

Further information on the drilling programme will be issued in due course.

Commenting on the test result Kevin Hart, BowLeven's CEO, said

'Whilst further evaluation is required to determine the extent of the IE Field
and associated reserves, the result of the IE-2 well has been very encouraging,
especially as flow rates were constrained by the test equipment.

The high liquids ratio and excellent deliverability combined with the Field's
close proximity to both the Bioko Island LNG facility and the Limbe Power
Station, should materially enhance the chance of a commercially viable
development'

John Morrow, Chief Operating Officer of BowLeven plc, a member of the Society of
Petroleum Engineers who holds a C.Eng, is the qualified person that has reviewed
and approved the technical information contained in this announcement.

Notes to the Editor:

BowLeven is an African oil and gas group, based in Edinburgh and traded on AIM
since December 2004.

BowLeven holds, through its wholly-owned subsidiary EurOil Limited, a 100%
equity interest in the Etinde Permit area being three shallow water blocks in
offshore Cameroon, West Africa; namely Blocks MHLP 5, MHLP 6 and MHLP 7. In
total BowLeven has approximately 2,300 km2 of exploration acreage located across
the Rio del Rey and Douala basins in the Etinde Permit. Bowleven has operated in
Cameroon since 1999.

The IE-2 well is located approximately 27 km from the power plant at Limbe in
Cameroon. The Cameroon Government has recently announced a cooperation agreement
with the Government of Equatorial Guinea to investigate a project to export gas
from Cameroon to the gas liquefaction plant on Bioko Island on Equatorial
Guinea. It is proposed that Limbe would be the gathering hub for any such
scheme.

The IE-2 well is an appraisal well to the IE-1 discovery made by Total in 1981.

BowLeven has also recently acquired First Africa Oil, which has a 100% equity
interest in both the EOV offshore block in Gabon, which contains an existing oil
discovery that it is seeking to develop, and the Epaemeno Block which is 1,340
km2 of exploration acreage in onshore Gabon which lies to the North of Shell's
recent discoveries in the Awoun Block.

BowLeven will announce its interim results on 22nd March.
