EDINBURGH, UK – New Age Cameroon Offshore Petroleum’s latest appraisal well on the Etinde field offshore Cameroon has been completed, according to partner Bowleven.
The IM-6 appraisal well was drilled to a TD of 3,550 m (11,647 ft). New Age achieved its main goal of delineating the wet gas/water contact location within the intra-Isongo 410 sand reservoir.
Etinde has in-place wet gas of around 0.9-1.1 tcf. IM-6 was targeting an incremental 0.7 tcf of wet gas in place from the 410 horizon.
However, despite gas shows and indications of condensate/light oil during drilling, the 410 sand package is largely water saturated at the IM-6 location.
The same applies to the shallower 510 sandstone formation, also penetrated by the well.
More positively, gas logging data collected in the 310 intra-Isongo formation revealed gas shows during drilling. And well log data and reservoir fluid samples from this interval suggest the Middle Isongo sections are of interest, as the two horizons both show condensate-rich reservoir fluid samples.
The well will now be P&A’d, and the rig will be relocated to the backup location, IE-4 to the east of IM-6 and northwest of the previously drilled IE-3 well.
The IE-4 well will target a previously undrilled sand package “Drillbit” of Intra-Isongo origin, thought to be analogous to the 410 sand package at the IM-5 location.
