HOUSTON, Sept. 28
– Two companies launched a second seismic survey on acreage in the Seychelles in the Indian Ocean off East Africa.

East African Exploration Ltd., a unit of Black Marlin Energy Ltd., Dubai, and Avana Petroleum began shooting 1,100 line-km of 2D seismic to better image potential reservoirs in numerous tilted fault blocks and better delineate leads mapped earlier.

A 3,650 line-km 2D survey in 2007 identified an extensive and deep sedimentary section between and around the granitic islands. The granitic features are linked to those that underpin giant Bombay High field and flank the Cambay basin on India’s west coast.

The survey area includes large structures in shallow and deep water and is near wells drilled by Amoco in 1980-81. The wells had oil shows that correlate well with the tar balls occasionally found on Seychelles beaches, suggesting an active hydrocarbon system.
