Tanzania Eyes Gas Reserves Boost After Mnazi Bay Offshore Discovery

French oil company Maurel & Prom (M&P) has confirmed a natural gas discovery in Tanzania's Mnazi Bay license, with preliminary estimates indicating approximately 200 billion cubic feet (bcf) of gas in a reservoir reached by drilling from onshore to a target 4.5 kilometers offshore.

The Kasa-1X exploration well, drilled in collaboration with Tanzania Petroleum Development Corporation (TPDC), encountered a gas reservoir with encouraging characteristics, according to M&P's activity report for the first nine months of 2026.

Drilling began in June, with the well reaching a target beneath 400 meters of water. The initial discovery was followed by a sidetrack that intersected 588 meters of reservoir.

Gas volumes associated with the discovery are currently estimated at approximately 200 bcf gross, equivalent to 120 bcf on M&P's 60% working interest basis.
