Statoil’s Lavani-2 exploration and appraisal well has resulted in a new natural gas discovery offshore Tanzania. The Lavani-2 well was drilled to a total depth of 5,270 meters (17,290 ft) in water depths of 2,580 meters (8,465 ft). Tanzania currently has limited upstream gas activity, but the government has issued a number of exploration and production licences and is looking to become a new gas hub.
The Statoil-operated Lavani-2 well successfully appraised the Lavani-1 discovery reservoir in the Palaeogene. When deepening the well to the second target, a separate and significant gas bearing reservoir in the Cretaceous was encountered.
The well was drilled by Ocean Rig Poseidon. The Lavani-2 well is located about 5 kilometers southeast of the Lavani-1 discovery well and 20 kilometers south of the Zafarani-1 well.
Statoil and its co-venturer ExxonMobil Exploration and Production Tanzania Limited will announce updated total volumes in Block 2 next year. An increase in the upside potential of the Block is expected following further evaluations of the well. The Lavani-2 discovery is the venture’s third discovery in 2012.
The Lavani-2 well also provides information that will be incorporated into models to help determine the optimal development concept for a possible natural gas development in Tanzania.
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 Limited holding the remaining 35%. Statoil has been in Tanzania since 2007, when it was awarded the licence for Block 2.
