East Africa and US-focused independent oil firm Aminex announced Wednesday that its Ntorya-1 exploration well in the Ruvuma Basin (*), onshore Tanzania, has encountered strong gas shows in good-quality reservoir sand after having drilled to a depth of 9,020 feet (2,750 meters).
The reservoir sand was encountered at a depth of 8,725 feet (2,660 meters).
A logging program will begin shortly to evaluate the new section drilled below 8,200 feet (2,500 meters) and a further update will be provided after the logging program has been completed.
The Ntorya-1 well is designed to test the high-quality Basal Tertiary and Upper Cretaceous sands previously encountered in the Likonde-1 well, 9 miles (14 kilometers) to the north.
Participants in the deepening of the well below 8,200 feet include operator Ndovu Resources (Aminex), with 75 percent, and Solo Oil (25 percent). (in RIGZONE)

- Ruvuma is one of the last under-explored major river basins in Africa, with onshore and offshore prospects present in both Tanzania to the north and Mozambique to the south.
- Aminex and partners hold the rights to virtually all the onshore Tanzanian acreage in the basin.
- Exxon-Mobil, BG, Statoil and Ophir hold contiguous, adjoining offshore acreage. On the Mozambique side, Anadarko and partners drilled the Windjammer deep water gas discovery in early 2010 and have an ongoing drilling programme.
- Likonde-1 was drilled by Aminex and partners in early 2010 and TD’d at 3,647 metres.
- Likonde-1 intersected two sandstone intervals of over 250 metres (820 feet) combined thickness with high gas readings and physical evidence of residual oil. Drilling had to be terminated in the deepest objectives due to high gas influx.
- Seismic reprocessing has been undertaken to aid evaluation of nearby leads.
- Drilling of Ntorya-1 well to the south of the Likonde location planned for Q4 2011
