Mnazi Bay

Mnazi Bay Gas Project

Mnazi Bay is a 756 km² gas field located onshore in the Mtwara region of Southern Tanzania, approximately 410km south of Dar es Salaam.

The asset is operated by Maurel & Prom (holding a 48.06% stake) with the Tanzania Petroleum Development Corporation (TPDC) (holding 20%) and Wentworth Resources (holding 31.94%) as joint venture partners under the Mnazi Bay Production Sharing Agreement.

Mnazi Bay Gas Production

Mnazi Bay produces 50% of Tanzania’s natural gas to power over 30% of the country’s electricity generation.

The gas from Mnazi Bay feeds into the National Natural Gas Infrastructure Pipeline (NNGI), the largest pipeline in East Africa, running from Mnazi Bay to Tanzania’s commercial capital, Dar es Salaam.

In 2021 Mnazi Bay gas production averaged 81.6 million standard cubic feet (MMscf) per day, an increase of 25% in production compared to 65.5 MMscf per day in 2020.

During H1 2022, Mnazi Bay recorded an average production of 92.3 MMscf of gas per day.

This is the highest average H1 production performance to date, above the 2022 FY guidance of 75-85 MMscf of gas per day.

The 2022 production guidance for Mnazi Bay is 75-85 MMscf per day based on reservoir performance, historic production data from Mnazi Bay and various assumptions on economic growth, industrial capacity, new energy initiatives, and the activities of other suppliers.
