Aminex, one of the first companies to promote East Africa’s hydrocarbons potential, has declared its Ntorya well in Tanzania’s onshore Ruvuma Basin to be a gas discovery (AE 225/14). Aminex failed to find hydrocarbons at the depth it originally anticipated, but drilled ahead to an additional target and found a sand interval of 25 metres between 2,660 metres and 2,685 metres, with a three-metre gas-bearing pay zone in sandstones with 20% porosity at the top, and a 16.5-metre-thick lower sandstone interval with further possible gas pay.
