Statoil has been in Tanzania since 2007 and has an office in Dar es Salaam.
In 2007 Statoil signed a production sharing agreement (PSA) for Block 2 with Tanzania Petroleum Cooperation (TPDC).
Statoil Tanzania AS is the operator with 65% working interest with ExxonMobil Exploration and Production Limited as a partner with 35% interest.
In 2012 and 2013 Statoil and its partner ExxonMobil made the significant Zafarani, Lavani and Tangawizi discoveries in Block 2, which covers an area of approximately 5,500 square kilometres and lies in water depths between 1,500 to 3,000 metres. The discoveries have proved 10-13 Tcf of recoverable gas resources and mark an important step towards a possible natural gas development in Tanzania.
Statoil acquired a 12 % interest in the Petrobras operated Block 6 in May 2013. The block covers 5,549 square kilometres in the Mafia basin, with a water depth of 1,800 metres. The transaction is subject to approval by Tanzanian authorities.
