Private player NewAge has hit disappointing results at its latest appraisal well on the Etinde block off Cameroon, where it plans a final investment decision on a development next year.
The company drilled the IM-6 probe with the Vantage Drilling-owned jack-up Topaz Driller to 3550 metres, deeper than the initial target as it hit higher-than-expected pressure due to gas shows at 3370.
This meant the partners plugged the well with cement and performed a sidetrack, block partner Bowleven said on Wednesday.
Although the primary objective of delineating the wet gas/water contact location within the intra-Isongo 410 sand reservoir was achieved, this sand package was found to be water saturated.

The shallower 510 sand package was water bearing, while the deeper 310 sand packages had gas shows.
“Following preliminary analysis of the well data, the decision has been made not to test the sand packages drilled at the IM-6 location. The well is currently being made ready to be plugged and abandoned,” Bowleven said.
NewAge and its partners have already discovered between around 900 billion and 1.1 trillion cubic feet of wet gas at the Etinde block, and were targeting an incremental 700 Bcf from the 410 horizon.
Bowleven chief executive Eli Chahin said: "Whilst it is disappointing that the IM-6 well did not make an additional commercial discovery, the data collected is vital in further defining the existing 410 intra-Isongo discovery.
“Specifically, after further analysis and reservoir engineering and modelling, we expect to be able to accurately delineate the location of the gas/water contact within the 410-wet gas reservoir and firm-up the reservoir volume.”
The rig will now move on to drill the IE-4 well east of IM-6, targeting a previously undrilled sand package.
Bowleven said any discovery at this well could prove up or de-risk a further 200 Bcf to 600 Bcf of resources.
