Ophir Energy provides the successful results of its three-well appraisal programme on the Jodari field, Block 1 Tanzania. Ophir holds 40% of Blocks 1, 3 and 4; the BG Group operates with 60%.

The Ophir-BG Joint Venture has successfully completed appraisal drilling on the Jodari asset, Block 1 offshore Tanzania. Three wells were drilled into the discovery: Jodari South-1, Jodari South ST-1 (a deviated side-track) and Jodari North-1.

The appraisal programme achieved its objectives:

• Demonstrated consistent, high-quality reservoir quality across the Jodari field • Reconfirmed the 3.4 TCF mean recoverable resource estimate • Confirmed the feasibility of high-angle (sub-horizontal) drilling thereby reducing development costs

Jodari South-1 was drilled 3.5km southwest of the Jodari-1 discovery well in 1,040m of water to a total depth of 3,441m TVDSS and was designed to evaluate the southern end of the Jodari field. The well was side-tracked to drill Jodari South ST-1 and drilled to 3,282m TVDSS as a high angle (sub-horizontal) well into the reservoir. Jodari North-1 was then drilled 6km north of the original Jodari-1 discovery well in 1,288m of water to 3,389m TVDSS to evaluate the northern accumulation.
