The discovery of an additional 2 trillion to 3 trillion cubic feet (tcf) of natural gas in the Piri-1 well brings the total of in-place volumes up to about 20 tcf in Block 2. “Since 2012 we have had a 100 per cent success rate in Tanzania and the area has become a core exploration area in a very short period of time,” said Mr Nick Maden, senior vice president for Statoil’s exploration activities in the Western Hemisphere, in a statement yesterday.
“We quickly went from drilling one well to a multi-well programme and with Piri-1 we are continuing the success.”
The new gas discovery was made in the same Lower Cretaceous sandstones as the gas discovery in the Zafarani-1 well drilled in 2012.
The discovery is Statoil and co-venturer The discovery is Statoil and co-venturer ExxonMobil’s sixth and the fifth high impact discovery in Block 2 offshore Tanzania. It was preceded by the four successful high-impact gas discoveries, Zafarani-1, Lavani-1, Tangawizi-1 and Mronge-1, and a sixth discovery in the Lavani-2 well beneath the Lavani-1 discovery. “Additional prospectivity has been mapped and will be tested throughout 2014 and 2015. We expect to drill several additional exploration and appraisal wells and hope that the results from these wells will continue to add gas volumes for a future large-scale gas infrastructure development,” said Maden.
Statoil operates the licence on Block 2 on behalf of Tanzania Petroleum Development Corporation and has a 65 per cent working interest. ExxonMobil Exploration and Production Tanzania Limited hold the remaining 35 per cent. Tanzania is a growing market with ongoing exciting discoveries, including 19 exploration blocks and $10-20 billion investment projected for exploration and production in the coming decade. Over the past two years, exploration in Tanzania’s deep offshore waters have led to the discovery of about 45 tcf of gas.
