Wentworth Resources, the independent, East Africa-focused oil & gas company, said it has completed the drilling operations at the MB-4 development well in the Mnazi Bay Concession, southern Tanzania.
The MB-4 development well was drilled to a total depth of 2,788 meters, and is located approximately 800 meters from the MB-2 and MB-3 wells in the Mnazi Bay gas field.
The well has crossed Miocene gas reservoirs with net pay of 24 meters and 43 meters respectively, both ranked among the best of the five wells drilled in this field to date, the company informed in a statement.
Pressure measurements have confirmed the lateral and the vertical connectivity of each reservoir.
Within this well two reservoirs have been 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, according to the statement.
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.
