Tanzania has inked a memorandum of agreement (MoU) to potentially develop and assess the country’s largest gas reserve, Mnazi bay gas field. The agreement was signed between Tanzania’s Petroleum Development Corporation (TDPC) representing Nigeria. On the other hand, Nigeria was represented by FIRST Exploration & Petroleum Development Company (FIRST E&P). Signed in Dodoma, the MoU marks a strategic step towards unlocking Tanzania’s natural gas potential Furthermore, it holds the promise of expanding energy access across the region. Under the agreement, FIRST E&P will fully fund the technical assessment phase.

This signals confidence in the block’s potential and the company’s long-term interest in Tanzania’s upstream sector. TPDC Managing Director, Mussa Makame, noted that the MoU allows both parties to review existing data. Furthermore, it allows them to conduct new studies and explore potential gas development and production opportunities. “The MoU is valid for nine months but could conclude earlier or be extended depending on the findings. The full cost implications will become clearer after the assessment phase,” he said. Mr Makame emphasized the significance of developing domestic gas resources. Tanzania is making significant advancements in its energy project other than Mnazi Bay gas field as its gas-to-liquid plant takes shape.

The plant is expected to be one of the nation’s most transformative industrial projects that will produce various products. These include diesel, jet fuel, naptha, hydrogen, and fertilizer. Moreover, it is expected to rival Nigeria-based Dangote refinery owned by Africa’s richest man, Aiko Dangote. The project advanced to a major milestone after completion of a feasibility study confirming the project’s economic and technical viability. The study was conducted by Canadian-based clean-fuel technology company, Rocky Mountain GTL. The planned $420 million investment could position Tanzania as Africa’s first exporter of synthetic jet fuel and diesel. Moreover, it would effectively capitalize on its 57.54 trillion cubic feet of natural gas. Representatives of Rocky Mountain GTL noted detailed commercial collaboration is already underway.
