Testing Update - Bomono Permit, Cameroon

Bowleven, the Africa focused oil and gas exploration group traded on AIM, is pleased to announce the following update on the extended well test programme underway at Bomono.

To date, the Moambe well has achieved a maximum stabilised flow rate of 7.3 mmscfd through a 48/64 choke with a flowing well head pressure of 664 psig with no signs of depletion during the initial test period. As a result of this success, the well has now moved into the planned extended test period. This is intended to confirm sustainable deliverability to a proposed gas-to-power development scheme. Initial indications are that under such a development scenario the Moambe well would be capable of delivering around 4 to 5 mmscfd.

Meanwhile, as testing continues at Moambe, we continue to progress plans to commence extended well testing at the Zingana well.

Further update announcements will be made in due course, as appropriate.

Kevin Hart, Chief Executive, said:

"We are pleased with the positive initial flow test results on Moambe which give us increased confidence in the commercial viability of future development plans at Bomono. We look forward to the Zingana test augmenting the results at Moambe and to progressing gas sales negotiations."

(2) Bowleven has a 100% interest in the Bomono Permit.

(3) Under a gas-to-power development scheme, a production rate of 5 mmscfd would be expected to generate approximately 25MW of power.

(4) As planned, the ongoing testing programme is targeting the shallower gas-prone sands which it is proposed will be used for the initial feedstock for power generation. Meanwhile, the evaluation of the potential of the deeper sands that were targeted and encountered with both wells is also continuing.
