Statoil and partner ExxonMobil report a large gas discovery (Lavani) in the Statoil-operated Block 2 licence offshore Tanzania. This is the second large offshore Tanzania discovery (Zafarani) reported by the partners. (Earlier post.)
The logging results from the Lavani well confirm a new high-impact discovery for Statoil, with a preliminary resource estimate of 3 trillion cubic feet (Tcf) of gas in place. The Lavani well has encountered 95 meters of excellent quality reservoir sandstone with high porosity and high permeability.
The result from Lavani, which is only 16 kilometres south of our recent Zafarani discovery, confirms the high potential in Block 2. We are also pleased to announce that the recently drilled Zafarani sidetrack added another 1 Tcf of gas in place. This is in addition to the up to 5 Tcf announced in February. The results so far mark an important step towards a possible natural gas development in Tanzania.—Tim Dodson, executive vice president for Exploration in Statoil

The Lavani well, drilled in 2,400-meter (7,874 feet) water depth, is the second exploration well in Block 2, which covers an area of approximately 5,500 square kilometers. The well is drilled by Ocean Rig Poseidon with operations still ongoing.
The Lavani discovery is the seventh high-impact discovery made by Statoil over the last 14 months. The other high-impact discoveries are Zafarani in Tanzania, Skrugard and Havis in the Barents Sea, Johan Sverdrup (formerly Aldous/Avaldsnes) in the North Sea, and Peregrino South and Pão de Açúcar (non-operated) in Brazil.
Statoil operates the licence on Block 2 on behalf of Tanzania Petroleum Development Corporation (TPDC) and has a 65% working interest, with ExxonMobil Exploration and Production Tanzania Ltd. holding the remaining 35%. Statoil has been in Tanzania since 2007, when it was awarded the licence for Block 2.
Statoil defines a high-impact well as one that can deliver a total of more than 250 million barrels of oil equivalent (boe), or 100 million boe net to Statoil.
