Bowleven (LON:BLVN) has made a hydrocarbon discovery offshore Cameroon with its Sapele-1ST well on Block MLHP-5 in the Etinde Permit of the Douala Basin.
The sidetrack well encountered a total of 23 meters of net hydrocarbon-bearing pay in the Omicron objectives based on the results of drilling, conventional wireline logs, samples of reservoir fluid and pressure data. A testing program is expected to commence shortly.
The Sapele-1ST well was drilled to a TVD of 3,634 meters (4,483 metres measured depth) in water depths of around 25 meters approximately 2 kilometers South East from the Deep Omicron oil discovery in the original vertical well.
Further detailed analysis, including test data, is now required to assess the implications of the Sapele-1ST well on current resource estimates. The impending Sapele-2 appraisal well results will also be integral to this process. The Company is now preparing to conduct a drill stem testing program at Sapele-1ST.
Following testing the intention is to release the Noble Tommy Craighead rig for a mandatory recertification process.
Due to the stratigraphic nature of the Omicron discoveries further appraisal will be required and is already under way and planned. The Sapele-2 well, intended to appraise both the Lower and Deep Omicron discoveries, is currently drilling with the Vantage Sapphire Driller rig and is expected to take a further 15 to 20 days (excluding testing).
The rig is available for up to three well slots after Sapele-2 with the location selection process factoring in both ongoing technical evaluation and well results.
