Apr 19, 2013 - Cobalt International recently completed a drill stem test (DST) on the Cameia-2 appraisal well in Block 21 offshore Angola. The test, which was conducted on the lowest drilled interval, did not produce any measurable hydrocarbons but did confirm the existence of an unexplored lower interval potentially capable of high flow rates across the Kwanza Basin. Hydrocarbons were confirmed in the same mound reservoir that was encountered in Cameia-1. The appraisal well was drilled by the Ocean Confidence (UDW semisub) and will now be plugged and abandoned for use in the Cameia Mound Development Project which is expected to be sanctioned in 2014.

Apr 19, 2013 - Bowleven released the final updated on the IM-5 appraisal/development well offshore Cameroon. A drill stem test (DST) has been performed on the Intra Isongo reservoir which marks the end of the successful drilling and testing program. The Intra Isongo test achieved a flow rate of 37 MMscfd and 4,4664 bcpd through a 64/64-inch choke from a 95-foot perforated interval. Intra Isongo results combined with Middle Isongo delivered a maximum flow rate of 60 MMcfd and 7,819 bcpd. The IM-5 well will now be suspended as a future producer.
