Statoil-ExxonMobil Venture Announce New Gas Discovery in Tanzania

Statoil and co-venturer ExxonMobil announced a fifth discovery in Block 2 offshore Tanzania of an additional 2-3 trillion cubic feet (Tcf)* of natural gas in place in the Mronge-1 well.

This brings the total of in-place volumes up to 17-20 Tcf in Block 2.

According to Nick Maden, Senior Vice-President for Statoil’s exploration activities in the Western hemisphere ” The Mronge-1 well discoveries further the potential for a natural gas development in Tanzania. The discoveries also demonstrate how Statoil’s strategy of focusing on high-impact opportunities is paying off and supports the company’s ambition for international growth”.

The Statoil-operated partnership started its new drilling campaign in Block 2 in September 2013.

In addition to Mronge-1, the campaign includes drilling of several new prospects and appraisal of previous discoveries. Following Mronge-1, the partnership is scheduled to appraise the 2012 Zafarani discovery.

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 operatorship for Block 2.
