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 Corporation (TPDC).
Statoil Tanzania AS is the operator with 65% working interest with ExxonMobil Exploration and Production Limited as a partner with 35% interest. The block covers an area of approximately 5,500 square kilometres and lies in water depths between 1,500 to 3,000 metres.
In 2012 and 2013 Statoil and its partner ExxonMobil made the significant Zafarani, Lavani, Tangawizi and Mronge discoveries. In 2014 the Piri and Giligiliani discoveries were made. In 2015 Statoil made the Mdalasini discovery. The discoveries combined have proved around 22 Tcf of in-place volumes 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.
