BG Group announced that its second Tanzanian exploration well, Chewa-1, has also discovered gas. The well, located in Block 4 approximately 80 kilometers offshore southern Tanzania in a water depth of around 1 300 meters, is some eight kilometres north-west of BG Group’s Pweza-1 gas discovery announced in last October.


Chewa-1, operated by Ophir Energy plc (40%), is the second of a three-well initial work program planned for Blocks 1, 3 and 4 offshore southern Tanzania. The initial work program also includes the acquisition of 4 000 square kilometers of 3D seismic data. BG Group (60%) has the option to assume operatorship of all three Blocks upon completion of the initial work program.

“This is an encouraging start to our campaign in Tanzania. We have a large acreage position to explore and an extensive exploration program will be needed to assess the full potential of this new play,” said BG Group Chief Executive Frank Chapman.
