Statoil makes another high-impact gas discovery offshore Tanzania

June 19, 2014

The discovery in the Piri prospect is Statoil and co-venturer ExxonMobil’s sixth discovery and the fifth high-impact discovery in Block 2 offshore Tanzania.

The discovery of an additional two to three trillion cubic feet (tcf*) of natural gas in place in the Piri-1 well brings the total of in-place volumes up to approximately 20 tcf in Block 2.

"Since 2012 we have had a 100% success rate in Tanzania and the area has become a core exploration area in a very short period of time. We quickly went from drilling one well to a multi-well programme, and with Piri-1 we are continuing the success," says Nick Maden, senior vice president for Statoil's exploration activities in the Western Hemisphere.

The new gas discovery was made in the same Lower Cretaceous sandstones as the gas discovery in the Zafarani-1 well drilled in 2012.

The Piri-1 discovery is the venture's sixth discovery in Block 2. It was preceded by the high-impact gas discoveries Zafarani-1, Lavani-1, Tangawizi-1 and Mronge-1, and a discovery in Lavani-2.

Piri-1 was drilled by the drillship Discoverer Americas. The well location is two kilometres southwest of the Lavani-1 well at 2,360-metre water depth. The Discoverer Americas has now moved location and is currently drilling the Binzari prospect in Block 2.
