Statoil confirms deepwater gas find offshore Tanzania

Offshore staff

STAVANGER, Norway – Statoil says its deepwater Zafarani discovery in block 2 off Tanzania is a large gas field. Logging results suggest at least 5 tcf of gas in place.

The well has so far encountered 120 m (393 ft) of good quality reservoir with high porosity and high permeability. No gas/water contact has yet been established, and drilling continues.

“This discovery could potentially be a catalyst for large scale natural gas developments in Tanzania,” says Yona Killaghane, managing director of Tanzania Petroleum Development Corp. (TPDC).

Earlier this week, Statoil and its partner ExxonMobil signed an addendum to the production sharing agreement for block 2, which clarifies the commercial terms for a gas field development in the block with the Tanzanian authorities.

Statoil was awarded the block license in 2007, which covers an area of 5,500 sq km (2,123 sq mi). Water depth at the Zafarani location is 2,582 m (8,471 ft). The well’s planned TD is 5,100 m (16,732 ft).

TPDC has the right to a 10% working interest in the development phase.   

After completing operations, the drillship, Ocean Rig Poseidon, will drill a second well in the block on the Lavani prospect.
