Ophir Energy plc (Ophir or the Company) reported Wednesday further successful appraisal of the Mzia discovery in Block 1, off Tanzania. Ophir holds 40 percent of Blocks 1, 3 and 4. BG Group operates with 60 percent.

The Mzia-3 appraisal well was drilled approximately 3.7 miles (6 kilometers) north of the original Mzia-1 discovery well and 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 183 feet (56 meters) of net pay combined in the Lower and Middle sands and has confirmed reservoir quality in-line with that seen in the Mzia-1 and Mzia-2 wells.

In addition, the gas down to level proven in Mzia-3 is 351 feet (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 c. 0.7 trillion cubic feet (Tcf) to c. 5.2 Tcf. Well completion operations are currently ongoing.

Nick Cooper, 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 (liquefied natural gas) 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.”
