Success of the MB-5 gas well in Tanzania

The drilling campaign launched last February on the Mnazi Bay permit in Tanzania has achieved a first major success. The MB-5 well—the first drilled on the license since 2014—has been on production since March 29, 2026, with a capacity of 40 mmcfd.

This new well increases the field’s production potential to over 130 mmcfd, enabling, for the first time, testing of the facilities at their design capacity (130 mmcfd) and beyond. It also strengthens the country’s gas supply security and power generation stability.

This achievement is the result of nearly two years of preparation, overcoming significant technical, operational, and administrative challenges. Operations were completed with zero LTI and within optimized timelines, with drilling achieved in 41 days versus 47 days initially planned.

A collective success reflecting the commitment, rigor, and professionalism of all teams involved, both in the subsidiary and at headquarters.

The campaign now continues with the MS-2 development well, to be followed by the Kasa-1X exploration well.
