About the Mnazi Bay Concession

The Mnazi Bay Concession Area is located in coastal, south-eastern Tanzania in the Rovuma (Ruvuma) Basin. The area lies between Aminex and Tullow Oil's Ruvuma Concession Area and Ophir Energy and BG Group's offshore Block 1. Ophir and BG Group's Chaza-1 gas discovery lies just northeast of Mnazi Bay's marine border. The 756 km² concession area contains two discovered Tertiary aged gas fields (Mnazi Bay and Msimbati) and holds additional Tertiary, Cretaceous and Jurassic hydrocarbon potential. Four wells have been drilled to date:  MB-1, MB-2, MB-3 and MS-1X, and all four wells encountered hydrocarbons. MB-1 is currently producing gas at a rate of 1.7-2.0mmscf/d and this gas is transported via an 8", 27 kilometre pipeline to the Mtwara Power Plant where it generates electricity for numerous local communities.
