Wentworth, the Oslo Stock Exchange and AIM listed independent, East Africa-focused oil & gas company, is pleased to announce the completion of drilling operations at the MB-4 development well in the Mnazi Bay Concession, southern Tanzania.

The MB-4 development well, drilled to a total depth of 2,788 meters (True Vertical Depth Sub Sea) and is located approximately 800 meters from the MB-2 and MB-3 wells in the Mnazi Bay gas field, has crossed Miocene gas reservoirs with net pay of 24 meters (Upper Mnazi Bay) and 43 meters (Lower Mnazi Bay) respectively, both ranked among the best of the five wells drilled in this field to date. Pressure measurements have confirmed the lateral and the vertical connectivity of each reservoir.

Within this well two reservoirs have been selectively tested at different two-hour stabilised flows with the Upper Mnazi Bay achieving a constrained flow-rate of up to 18.8 mmscf/day and the Lower Mnazi Bay of up to 22.2 mmscf/day.

The well will be connected to the production facilities which are currently being installed in the field, for start-up in Q3 2015. These results confirm the Mnazi Bay gas field's ability to produce output over and above the initial 80 mmscf/day, possibly up to 130 mmscf/day. MB-4 well was deepened to the Oligocene where it encountered high-pressure intervals of unknown origin. Wentworth has a 31.94% net interest in this well, which was operated by Maurel et Prom.

Geoff Bury, Managing Director, commented:

"We are extremely pleased with the outcome of the MB-4 well as the result confirms our reservoir model for the Mnazi Bay gas field. The success of the well not only provides further confirmation of the value of our discovered reserves in Mnazi Bay, but also provides additional flexibility for meeting gas delivery obligations agreed in our Gas Sales Agreement. We look forward to the start of production in the third quarter as a transformational step for the Company."
