Statoil and co-venturer ExxonMobil have carried out a successful first drill stem test on their Tanzania Block 2 offshore discovery Zafarani-2.

The data acquired will help reduce technical uncertainties in a possible future Tanzania offshore and LNG development, said Statoil.

The Zafarani-2 operation tested two separate intervals and flowed at a maximum of 66MMcf/d, constrained by equipment, and confirmed good reservoir quality and connectivity.

The drill stem test operation was performed through a re-entry in the Zafarani-2 well, in 2400m water depth and about 80m off the coast of southern Tanzania.

The ongoing appraisal program is crucial to firm up the design and development basis for bringing gas to shore and a first phase onshore LNG project in Tanzania,” says Øystein Michelsen, Statoil’s Tanzania country manager.

“We are now working constructively with our co-venturer ExxonMobil, Blocks 1, 3 and 4 and the Tanzanian authorities to progress the plans for a joint LNG plant development.”

The Zafarani-2 operation will be followed by the appraisal well Zafarani-3, which concludes the planned appraisal in the Zafarani reservoir, the cornerstone for a field development in Tanzania Block 2, Statoil says.

The Zafarani-2 well test announcement follows the Mronge-1 discovery made in December 2013, which was the fifth discovery in Block 2 and brought the natural gas in place volumes up to 17-20Tcf.

The Mronge-1 was preceded by three successful high-impact gas discoveries during the first drilling phase with Tangawizi-1, Zafarani-1, and Lavani-1, and a deeper discovery in a separate reservoir in Lavani-2. 

Statoil operates the license on Block 2 on behalf of Tanzania Petroleum Development Corporation (TPDC) and has a 65% working interest, with ExxonMobil Exploration and Production Tanzania Limited holding the remaining 35%.

Statoil has been in Tanzania since 2007, when it was awarded the operatorship for Block 2.
