Statoil’s Mdalasini-1 exploration well has resulted in a new natural gas discovery offshore Tanzania. The discovery of an additional 1.0-1.8 trillion cubic feet (tcf) of natural gas in place in the Mdalasini-1 well brings the total of in-place volumes up to 22 tcf in Block 2.
The Mdalasini-1 discovery is located at a 2,296-meter water depth at the southernmost edge of the block. The new gas discovery has been made in Tertiary and Cretaceous sandstones.
Statoil has drilled the Mdalasini-1 well with a 100% working interest. Previously, Statoil and co-venturer ExxonMobil have made seven discoveries in Block 2, including the gas discoveries Zafarani-1, Lavani-1, Tangawizi-1, Mronge-1, and Piri-1, as well as the discoveries in Lavani-2 and Gilligiliani-1.
Statoil operates the license on Block 2 on behalf of Tanzania Petroleum Development Corp. (TPDC) and has a 65% working interest. ExxonMobil Exploration and Production Tanzania Ltd. holds the remaining 35%. TPDC has the right to a 10% working interest in case of a development phase. Statoil has been in Tanzania since 2007, when it was awarded the operatorship for Block 2.
