Aminex PLC provides the results from deepening the Ntorya-1 exploration well in the Ruvuma Basin onshore in Tanzania.

On February 27th 2012, Aminex reported that a gas discovery had been made in a 25 metre gross sand interval between 2,660 metres and 2,685 metres with a 3 metre net gas bearing pay zone in sandstones having 20% porosity at the top and a 16.5 metre thick lower sandstone interval with further possible gas pay.

After running a 7-inch liner to 2,750 metres, the well was deepened to a final total depth of 3,150 metres and wireline logging was carried out. Although encouraging gas readings were recorded over a 300 metre interval from 2,850 metres to TD, a deeper target horizon identified on seismic at approximately 3,000 metres was found not to have reservoir potential.
