Bowleven announced that the Sapele-1 exploration well drilling in the Douala Basin, offshore Cameroon has encountered further log evaluated pay in the Miocene reservoir objective. This pay is in addition to that encountered at the Lower and Deep Omicron discoveries announced on November 9, 2010.
The targets of the Sapele-1 exploration well, on block MLHP-5 in the Etinde Permit, are a series of vertically stacked reservoir objectives, from the proven Miocene fairway down to the deeper Cretaceous fairway proven to be prolific elsewhere in West Africa.
Since the announcement on November 9, 2010, the well, which is drilling in water depths of around 20 meters, has been deepened by a further 123 meters to a current total depth of 3,483 meters in order to find a suitable point to set casing before drilling ahead into the cross-cut event.
The initial results from this section indicate that the well has intersected additional net hydrocarbon pay of 6 to 8 meters in high quality reservoir sands with an average porosity of 21%.
Forward exploration and appraisal program
It is now planned to drill, using jackup GSF Adriatic VI, to a target depth (TD) of approximately 4,450 meters to test further prospective horizons, including the deeper Cretaceous, a play untested within this part of the Douala Basin.
Drilling activity is expected to take a further 20 to 30 days (excluding testing). In the meantime planning for testing and appraisal drilling/sidetracking activities on the Omicron discoveries is underway. The forward plan will be reviewed by the joint venture on reaching TD.
Kevin Hart, Chief Executive of Bowleven, commented, "While we recognize that further evaluation and appraisal are required, the additional pay encountered in the Miocene section provides further support to our view that the Omicron discoveries are potentially transformational. We look forward with anticipation to recommencing drilling and intersecting the deeper cross-cut event and Cretaceous Epsilon targets."
