Tanzania has announced the discovery of an estimated 223 billion cubic feet of natural gas in its southern Mnazi Bay area, marking the country’s first new gas discovery in more than a decade and opening the possibility of additional domestic energy production.
The discovery was announced on Tuesday, October 27, 2026, by Tanzania’s Energy Minister, Juma Homera, who confirmed that the gas was found at the Kasa-1X ST2 well. The exploration was undertaken jointly by the state-owned Tanzania Petroleum Development Corporation (TPDC) and French energy company Maurel & Prom.
According to Reuters, the Tanzania Natural Gas Discovery comes as the government seeks to strengthen domestic gas supply and attract investment into smaller liquefied natural gas developments.
The new find adds to Tanzania’s established gas resource base, which stood at approximately 57.5 trillion standard cubic feet before the latest announcement, according to the country’s energy regulator.
The development also places renewed attention on the Mnazi Bay Gas Project, where exploration activity is creating opportunities for additional production and investment.
Tanzania Natural Gas Discovery Confirms 223 Billion Cubic Feet at Kasa-1X ST2
Energy Minister Juma Homera announced that the estimated 223 billion cubic feet of natural gas had been discovered at the Kasa-1X ST2 well in the Mnazi Bay area of southern Tanzania.
The Tanzania Natural Gas Discovery represents the country’s first reported gas find in more than ten years.
The well was explored through a partnership between TPDC and Maurel & Prom, bringing together Tanzania’s state petroleum company and an established international energy operator.
The announcement provides a new development for Tanzania’s natural gas sector, which has previously identified substantial gas resources.
The 223 billion cubic feet figure represents an estimated volume associated with the discovery. It should not be interpreted as a confirmed amount of gas already produced or available for immediate commercial sale.
Further technical and commercial work may be required before the full production potential of the discovery can be established.
The Reuters report does not specify the recoverable portion of the estimated volume, the expected operating lifespan of the well or the financial value of the discovery.
Those details will be important in determining the project’s eventual commercial contribution.
For now, the confirmed development is that Tanzania has identified an additional gas resource at Kasa-1X ST2, with the government expecting the wider drilling programme to support domestic supply.
Mnazi Bay Gas Project Involves TPDC and Maurel & Prom
The latest discovery follows exploration activity undertaken jointly by Tanzania Petroleum Development Corporation and French oil and gas company Maurel & Prom.
The partnership is central to the Mnazi Bay Gas Project because it combines the participation of Tanzania’s national petroleum company with the technical and operational involvement of an international energy firm.
According to Homera, the two companies have drilled three wells identified as MB-5, MS-2 and Kasa-1X ST2.
The minister said the wells would contribute to increasing Tanzania’s gas supply.
The Kasa-1X ST2 well is the location of the newly announced discovery, while the other two wells form part of the drilling activity described by the minister.
The Reuters report does not provide separate gas volumes for MB-5 and MS-2 or establish that all three wells contain newly discovered reserves.
It also does not disclose the total cost of the drilling programme or the financial contributions of the participating companies.
Nevertheless, the development represents a continuation of exploration and production activity in southern Tanzania.
The participation of TPDC is significant because the corporation is directly involved in the country’s petroleum sector and the development of domestic gas resources.
Maurel & Prom’s involvement provides an international commercial dimension to the project.
Together, the companies are pursuing gas development activities that the government expects to contribute to the country’s energy supply.

Tanzania Natural Gas Discovery Marks First New Find in More Than a Decade
The latest announcement is significant because Tanzania has not reported a new natural gas discovery of this kind for more than ten years.
The Tanzania Natural Gas Discovery therefore marks an important development in the country’s exploration activity.
The discovery comes after Tanzania had already established a substantial natural gas resource base.
According to the country’s energy regulator, previously discovered reserves stood at approximately 57.5 trillion standard cubic feet before the new find was announced.
The latest estimated volume of 223 billion cubic feet is equivalent to 0.223 trillion cubic feet.
On a simple arithmetic basis, adding the newly announced estimate to the previously reported figure would produce approximately 57.723 trillion cubic feet.
However, that calculation should not be presented as a newly certified national reserve total.
The figures may reflect different technical classifications, and the Reuters report does not state that the energy regulator has formally revised Tanzania’s reserve estimate.
The important distinction is between the announcement of a discovery and the formal assessment of reserves available for commercial extraction.
The latest find provides evidence of additional gas resources, but its contribution to national production will depend on subsequent development.
The announcement also highlights the continuing role of exploration in identifying new resources even in countries with established petroleum discoveries.
Mnazi Bay Gas Project Could Begin Additional Production in November 2026
Maurel & Prom has indicated that first gas production could begin as early as November 2026.
The statement introduces a potential near-term production milestone for the Mnazi Bay Gas Project.
However, the company has described November as the earliest possible starting period, not a confirmed production commencement date.
The Reuters report does not specify which of the three wells would begin production first or provide a daily production target.
It also does not establish that commercial production from the newly discovered Kasa-1X ST2 resource has already started.
These distinctions are important because the discovery of gas and the delivery of gas into the market are separate stages of energy development.
Before gas can contribute to supply, the relevant wells and supporting infrastructure must be ready for production and transportation.
The company’s production outlook suggests that the development programme may soon begin contributing additional volumes.
The scale and timing of those contributions will depend on operational progress and further announcements.
For Tanzania, the possibility of production beginning in November offers an opportunity to translate exploration activity into practical energy supply.
Tanzania Natural Gas Discovery Supports Plans to Expand Domestic Gas Supply
The government expects the drilling programme involving MB-5, MS-2 and Kasa-1X ST2 to strengthen Tanzania’s natural gas supply.
Energy Minister Juma Homera identified the three wells as developments that could contribute to the country’s gas availability.
The Tanzania Natural Gas Discovery adds another potential source of supply to the country’s established petroleum resource base.
Natural gas is relevant to economic activity because it can be used for electricity generation and industrial energy requirements, depending on available infrastructure and commercial arrangements.
Additional domestic production could create opportunities for gas consumers if the resource is successfully developed and connected to the relevant supply systems.
However, the Reuters report does not specify how much of the new gas would be allocated to electricity generation, industrial users or other domestic consumers.
It also does not announce a reduction in electricity tariffs or natural gas prices.
The government has therefore identified a potential supply benefit, but the specific economic effects remain to be determined.
The eventual contribution will depend on the amount of gas produced, the reliability of operations and the arrangements governing its distribution.
For the wider energy sector, the development represents another opportunity to expand the use of Tanzania’s domestic resources.
Mnazi Bay Gas Project Draws Interest in Small-Scale LNG Investment
Alongside the discovery, Tanzania is pursuing discussions with investors interested in small-scale liquefied natural gas developments.
Energy Minister Juma Homera said TPDC was already holding talks with four investors planning small-scale LNG projects.
The discussions add an investment dimension to the Mnazi Bay Gas Project and Tanzania’s wider natural gas development plans.
Liquefied natural gas is natural gas that has been cooled into liquid form, allowing it to be stored and transported more efficiently under appropriate conditions.
Small-scale LNG developments can serve markets where conventional pipeline distribution may be limited or where smaller volumes of gas are required.
However, the Reuters report does not identify the four investors or disclose the proposed locations, capacities or costs of their projects.
It also does not confirm that final investment agreements have been signed.
The discussions should therefore be described as ongoing investor engagement rather than completed project commitments.
The minister’s announcement indicates that Tanzania is seeking additional commercial opportunities connected to its gas resources.
Whether those discussions lead to operational LNG facilities will depend on further negotiations, investment decisions and project development.
The latest discovery may contribute to interest in the sector, but the report does not establish that all four proposed projects will use gas from Kasa-1X ST2.
Tanzania Natural Gas Discovery Highlights the Role of State and International Partnerships
The exploration programme demonstrates the role of partnerships in Tanzania’s petroleum sector.
TPDC and Maurel & Prom jointly explored the Kasa-1X ST2 well where the new gas resource was identified.
The Tanzania Natural Gas Discovery is therefore linked to cooperation between a national petroleum corporation and an international energy company.
Such arrangements can bring together local institutional participation and technical capabilities required for exploration and development.
However, the commercial structure of each partnership depends on its specific contractual terms.
The Reuters report does not disclose the ownership percentages, revenue-sharing arrangements or other financial conditions governing the latest discovery.
It would therefore be premature to calculate the revenue Tanzania may receive from the new resource.
The confirmed information is that TPDC and Maurel & Prom undertook the exploration jointly and have drilled three wells intended to increase supply.
The development also comes as the state-owned corporation engages potential investors in small-scale LNG projects.
Together, these activities indicate that Tanzania is pursuing additional gas development through both exploration partnerships and investor discussions.
Mnazi Bay Gas Project Adds to Tanzania’s Established Energy Resources
Tanzania already has substantial discovered natural gas resources, with the country’s energy regulator reporting approximately 57.5 trillion standard cubic feet before the latest announcement.
The new discovery adds an estimated 223 billion cubic feet to the resource picture.
The Mnazi Bay Gas Project is significant because it represents activity within a country that already has an established natural gas sector.
The development may strengthen the available resource base, although the full commercial contribution of the new find has not been established.
The distinction between discovered resources and actual production remains important.
A country may possess substantial gas resources without producing the entire volume immediately.
Commercial extraction depends on development decisions, infrastructure and the economic viability of individual projects.
In Tanzania’s case, the potential November production timeline suggests that the companies involved are pursuing near-term supply opportunities.
However, the Reuters report does not provide a detailed production schedule extending beyond the possible initial start date.
Further announcements will be needed to determine how the three wells contribute to national gas output.
The ongoing LNG investor discussions also suggest that Tanzania is exploring additional ways to develop and commercialise its gas resources.
What This Means For Africa
Tanzania’s latest gas discovery is relevant to Africa’s energy outlook because it demonstrates continued exploration activity and investment interest in the continent’s natural gas sector.
The Tanzania Natural Gas Discovery of an estimated 223 billion cubic feet marks the country’s first reported new find in more than a decade.
For East Africa, the development adds attention to Tanzania’s potential role in supplying natural gas for domestic economic activity.
Additional gas production could create opportunities for electricity generation and industrial energy use, depending on the infrastructure and commercial arrangements developed.
However, the discovery does not automatically establish that new gas supplies will be available across neighbouring countries.
Any regional trade opportunities would require appropriate transportation systems, agreements and market demand.
The Mnazi Bay Gas Project also illustrates the role of cooperation between African state-owned petroleum companies and international energy firms.
TPDC’s partnership with Maurel & Prom has produced a new discovery, while the corporation’s discussions with four potential LNG investors indicate further interest in gas development.
These developments are relevant to African governments assessing how domestic resources can support energy supply and economic activity.
The project also demonstrates the importance of distinguishing resource discoveries from commercial production.
Although Maurel & Prom has indicated that first gas could begin flowing as early as November 2026, the timing and scale of production remain subject to confirmation.
For Tanzania, the next stage will involve translating exploration results into reliable supply and determining the commercial potential of the newly identified resource.
The country’s previously reported 57.5 trillion standard cubic feet of discovered reserves provides context for the additional 223 billion cubic feet announced by the government.
The latest development is modest relative to that existing resource base, but its importance also lies in the resumption of reported discoveries after more than ten years.
Across Africa, new gas discoveries can create investment opportunities while raising practical questions about infrastructure, financing and the eventual use of energy resources.
Tanzania’s announcement provides a concrete example of those opportunities through its ongoing exploration programme and investor discussions.
For now, the confirmed milestone is the discovery of an estimated 223 billion cubic feet at Kasa-1X ST2, with the government expecting the three-well drilling programme to contribute to domestic gas supply.
The Tanzania Natural Gas Discovery will be followed closely as Maurel & Prom approaches its possible November production timeline and TPDC continues discussions on small-scale LNG developments.
