Wentworth Resources Discovers Gas at MB-4 Well in Tanzania

Wentworth Resources announced Wednesday that it has discovered gas at the MB-4 development well in the Mnazi Bay Concession, located in southern Tanzania.

The well was drilled to a total depth of 9,146 feet and encountered a total of 219 feet of net pay across two targeted reservoirs, the Lower Mnazi Bay and the Upper Mnazi Bay. A flow rate of 22.2 million cubic feet per day was recorded at the Lower Mnazi Bay reservoir, with 18.8 MMcf recorded at the Upper Mnazi reservoir.

The MB-4 well will be connected to production facilities currently being installed in the field, for start-up in 3Q 2015. Wentworth believes the Mnazi Bay gas field has the potential to produce output up to 130 MMcf per day.

Wentworth Resources Managing Director Geoff Bury commented in a company statement:

"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."

Wentworth has a 31.94 percent net interest in the MB-4 well, which was operated by Maurel et Prom.
