Bowleven says that the IM-5 well drilling offshore Cameroon has now reached the Middle Isongo primary objective of the well and has encountered liquids-rich hydrocarbon-bearing pay in both this and the Intra Isongo reservoir objectives based on the results of drilling, core analysis, wireline logs, fluid samples and pressure data.

The well, which was designed to appraise the reservoir and fluid properties of the Middle Isongo and to explore the additional potential of the Intra Isongo, has reached TD of 3,430 meters MD. The forward program is to set liner and conduct testing operations.

The primary objective of the IM-5 appraisal/development well was to appraise the reservoir and fluid properties of the Middle Isongo sands. The secondary objective of the well was to investigate the additional potential of the Intra Isongo exploration prospect, a potentially extensive amplitude supported channel system potentially comprising both structural and stratigraphic trapping elements. The well was also designed to intersect the Upper Isongo sands and confirm that these were present at this location and water-bearing as prognosed.
