Maurel & Prom has confirmed a gas discovery at the Mnazi Bay licence in Tanzania, with its Kasa-1X exploration well encountering a gas-bearing reservoir on first penetration. The well was drilled directionally from the coast to a subsea target approximately 4.5 kilometres offshore under 400 metres of water. The immediate success on first penetration is a positive technical signal for the licence's prospectivity.
Following the initial discovery, M&P sidetracked the well with a horizontal section to further appraise and characterise the reservoir. The decision to sidtrack immediately after discovery suggests the operator has confidence in the find and is already moving to define its commercial dimensions. Mnazi Bay is an established gas-producing area in southern Tanzania, and this new well adds to the evidence base for additional resource potential within the licence perimeter.
For Tanzania, the Kasa-1X result arrives at a time when the country is working to develop its considerable natural gas resources, both for domestic power generation and as a potential feedstock for export infrastructure. The Mnazi Bay area has historically supplied gas to onshore Tanzanian consumers, and any meaningful addition to reserves could support both local supply commitments and longer-term LNG or regional pipeline ambitions. M&P's willingness to commit exploration capital to the licence underlines continued industry confidence in Tanzania's gas fairway, even as the broader East African LNG development landscape remains complex.
The well's directional geometry — drilled from shore to a point under 400 metres of water — is technically notable. This approach allows operators to access offshore targets while managing some of the logistical and regulatory complexity associated with fully offshore operations. The horizontal sidetrack in particular reflects modern well-design practice aimed at maximising reservoir contact and early flow-rate potential. Further results from the well, including any flow-test data or reserve estimates, have not been disclosed in available reporting at this stage.
