Ophir Energy and BG Group have recorded more success offshore Tanzania with the drilling of an appraisal well on Block 1. The appraisal well of the Mzia discovery, the Mzia-3, was drilled about six km north of the original Mzia-1 discovery well.
The well targeted the main Lower sands that comprise the majority of the resource in the field and upside in the Middle sand package that was encountered in the Mzia-1 well. The well encountered 56 meters of net pay combined in the Lower and Middle sands and has confirmed reservoir quality in-line with that seen in the two previous Mzia wells.
In addition, the gas down to level proven in Mzia-3 is 107 meters deeper than that seen in the previous wells, leading to an increase in discovered resource estimates. Provisional interpretation of the Mzia-3 result has increased the overall mean contingent recoverable resource for the Mzia discovery by around 0.7 Tcf, bringing mean contingent recoverable resources for the Mzia to around 5.2 Tcf. Well completion operations are currently ongoing.
Nick Cooper, Ophir CEO, commented: “The Mzia-3 result is another positive appraisal well on our discoveries in Blocks 1, 3 and 4 and confirms Mzia as an anchor asset in the planned LNG development. Total discovered resources are now comfortably in excess of that needed for two trains of LNG and demonstrate the potential for further long-term growth of the project.”
