Tanzania gas discovery, its first in 10 years: output may start in November

What happened. Tanzania's energy minister Juma Homera said about 223 billion cubic feet of gas was found in the Mnazi Bay area in the south. Reuters says the Kasa-1X ST2 well made the find. It was drilled by state-owned Tanzania Petroleum Development Corporation (TPDC) and France's Maurel & Prom. BBC reports the minister called it a "major milestone".

How big. 223 billion cubic feet is about 6.3 billion cubic metres. Before this, Tanzania's discovered reserves stood at about 57.5 trillion cubic feet, according to the energy regulator. So the find is small for the country, but it sits next to working infrastructure. On 22 October Maurel & Prom put the find at about 200 billion cubic feet, with 120 billion net to its 60% stake.

When the gas comes. Maurel & Prom says output could start as early as November 2026, with potential of about 50 million cubic feet a day. With two new wells, MB-5 and MS-2, Mnazi Bay's potential rises to nearly 200 million cubic feet a day, up from about 130 million now.

What it is for. BBC says the gas will go to the home market: power generation, industry and vehicles. Homera also said TPDC is in talks with four investors planning small-scale liquefied natural gas (LNG) projects.

A bit of history. Tanzania first found gas on Songo Songo Island in 1974, found Mnazi Bay in 1982, and started commercial output in 2004. Its largest single find, 2.7 trillion cubic feet, came in 2016.

Our take. This will not move world gas prices: the volume is small. But it is real news for Tanzania's energy supply and for Maurel & Prom shares. This is not advice to buy or sell anything.

Confirmed facts

• On 27 October Tanzania's energy minister Juma Homera announced an estimated 223 billion cubic feet of gas at Mnazi Bay.^[1][2]
• The gas was found by the Kasa-1X ST2 well, explored jointly by TPDC and Maurel & Prom. It is the country's first gas discovery in more than 10 years.^[1]
• 223 billion cubic feet is about 6.3 billion cubic metres. Tanzania's discovered reserves were about 57.5 trillion cubic feet before this.^[1][2]
• Maurel & Prom estimates the find at about 200 billion cubic feet on a 100% basis, 120 billion net to its 60% stake, with well potential of about 50 million cubic feet a day.^[3]
• Maurel & Prom says production could start as early as November 2026.^[1][3]
• TPDC is in talks with four investors planning small-scale LNG projects.^[1]
• The gas is meant for the home market: power generation, industry and vehicles.^[2]

Implications

• ConfirmedMnazi Bay output should rise: Maurel & Prom puts the field's potential at nearly 200 million cubic feet a day.
• Our readingMore local gas could cut Tanzania's need for costly imported fuel for power plants.
• Our readingWorld gas prices will barely notice the find because the volume is small.

Still unknown

• Whether output starts in November and at what real flow rate.
• Why the estimates differ: 223 billion from the ministry, about 200 billion from Maurel & Prom.
• Whether and when small LNG deals get signed.
