Norway’s Statoil said Monday that it discovered a new natural gas pay zone at its Mdalasini-1 exploration well in offshore Tanzania.
The Mdalasini-1 discovery is located at a water depth of 7,532 feet at the southernmost edge of Block 2.
The discovery was made in Tertiary and Cretaceous sandstones, Statoil said.
The find will add an estimated 1.0 to 1.8 trillion cubic feet of natural gas in place to the block’s total reserves, bringing total in-place volumes at the Block 2 to about 22 trillion cubic feet.
“The Mdalasini-1 discovery marks the completion of the first phase of an efficient and successful multi-well exploration programme offshore Tanzania,” senior vice president for Statoil’s exploration activities in the Western Hemisphere Nick Maden said.
Since the start of its drilling program in February 2012 Statoil has drilled 13 wells and made eight discoveries at the block including five high-impact gas discoveries Zafarani-1, Lavani-1, Tangawizi-1, Mronge-1 and Piri-1.
“We still see prospectivity in the area, but after appraising the Tangawizi-1 high-impact discovery, which was made in March 2013, there will be a pause in the drilling to evaluate the next steps and to mature new prospects,” Maden added.
Statoil holds a 100 percent working interest in the Mdalasini-1 well and also operates Block 2 on behalf of the Tanzania Petroleum Development Corporation (TPDC) with a 65 percent working interest.
ExxonMobil Exploration and Production Tanzania Limited holds a 35 percent working interest in the block.
TPDC has the right to a 10 percent working interest in case of a development phase.
