The facts
Energy Minister Juma Zuberi Homera announced the 223 billion cubic feet estimate for the Kasa-1X ST2 well in Mtwara, The Citizen reported. [2]
Maurel & Prom put the discovery at approximately 200 billion cubic feet gross, or 120 billion net to its 60% interest, describing these as early estimates. [1]
The operator envisaged first production as early as November 2026, with potential gross output of 50 million cubic feet a day. These were forecasts, not confirmation of production. [1]
The Chanzo reported the difference between the government and operator figures and said neither announcement classified the volume as certified recoverable reserves. [3]
Still unconfirmed
- The reason for the different estimates, the certified recoverable quantity and eventual production date remain unconfirmed.
