Statoil has made its seventh discovery in block 2, offshore Tanzania, with the Giligiliani-1 exploration well finding one trillion cubic feet (tcf) of natural gas in place.
The latest discovery, which brings the total of in-place volumes up to about 21tcf of natural gas in block 2, was made in Upper Cretaceous sandstones along the western side of the block in 2,500m of water.
Statoil Western Hemisphere exploration activities senior vice-president Nick Maden said: "This discovery has proven the gas play extends into the western part of block 2, which opens additional prospects.
"Our success rate in Tanzania has been high and opening up a new area will be key to continuing our successful multi-well programme."
Statoil has a 65% working interest and operates the block 2 licence on behalf of Tanzania Petroleum Development Corporation (TPDC); ExxonMobil Exploration & Production Tanzania holds the remaining stake.
Earlier discoveries in the block include the Zafarani-1, Lavani-1, Tangawizi-1, Mronge-1, Piri-1, and Lavani-2 gas discoveries.
The Giligiliani-1 well was drilled using the Discoverer Americas rig, which will now move to the Kungamanga prospect, situated in the central region of block 2.
