Yaounde, Cameroon Africa(Cameroon News) – Bowleven has announced a latest update on Sapele-2 Well, that is located offshore Cameroon.
Bowleven, the oil and gas explorer, trading on AIM, who has projects in West Africa, has revealed that the Sapele-2 well drilling in the Douala Basin, offshore Cameroon has come across a total of approximately 35 metres of independently log assessed net hydrocarbon-bearing pay in the Omicron objectives after evaluating the results of drilling and traditional wireline logs. A testing programme is being proposed, depending on securing various approvals, on finishing the logging programme.

Highlights
• Approximately 35 metres of independently log evaluated net hydrocarbon pay determined in the Omicron objectives at Sapele-2.
• Getting ready for testing programme at Sapele-2.
• Sapele-1ST testing programme happening.
Sapele-2 drilling update
The major objective of the Sapele-2 well was to review the Omicron discoveries come across in the Sapele-1 exploration well. The well was drilled to a total depth (TD) of 3,749 metres as proposed in water depths of 25 metres, going into both the Lower and Deep Omicron reservoir objectives at a location around five kilometres South West of the Sapele-1 location.
Bowleven, as operator, offers updates for the reservoir intervals that had been located at Sapele-2 below:
Lower Omicron
On the basis of traditional wireline logs, provisional net pay is independently approximated to be 19 metres, with an average porosity of 17%.
Deep Omicron
Based on conventional wireline logs, provisional net pay is independently estimated to be approximately 16 metres, based on conventional wireline logs, with an average porosity of 17%.
In both intervals the GC tracer has revealed the probable presence of oil however due to borehole issues it was not considered appropriate to take out reservoir fluid samples at this stage. It is however been planned that both hydrocarbon type and formation pressure will be confirmed during the future test programme.
Forward plan
Further detailed review, including test data, is now needed to determine the implications of both the Sapele-2 and Sapele-1ST wells on current resource estimates. A testing programme is currently being done on Sapele-1ST and the results are anticipated to be announced in the coming two to three weeks. An update on Sapele-2 testing is anticipated in the next three to four weeks.
Due to the stratigraphic nature of the Omicron fields more drilling will be needed to find out with greater confidence the potential size of these prevalent discoveries.
