UK-based Ophir Energy has revealed results from its Taachui-1 and subsequent Taachui-1 ST1 well in Block 1, Tanzania, resulting in a new gas discovery with a net pay of 155m.

The company said the Taachui-1 well was drilled by the Deepsea Metro I drillship close to the western boundary of Block 1.

The Taachui-1 well was drilled down to 4,215m and gas was found in a 289m single column.

"Drill-stem testing of Taachui-1 will now be carried out and the results are anticipated before the end of June 2014."

Ophir Energy said the well is estimated to contain one trillion cubic feet of recoverable gas and the discovery may extend into a second compartment to the west that could be of a similar size; an appraisal well would be required to confirm the theory.

Drill-stem testing of Taachui-1 will now be carried out and the results are anticipated before the end of June 2014.

Ophir Energy holds 20% of blocks 1, 3 and 4 at the Taachui wellm, and BG Group operates with 60%.

Ophir Energy CEO Nick Cooper said: "The Taachui-1 discovery continues the 100% drilling success rate on Blocks 1, 3 and 4 and adds further resource to support the LNG development in Tanzania.

"The result is important to Ophir for two reasons: firstly, it extends the proven hydrocarbon system to the eastern limit of, and partly de-risks, Ophir’s East Pande permit, on which the Tende-1 well will be drilled later in 2014.

"Secondly, the aggregate recoverable volumes of c.16.7 TCF are now approaching the threshold needed to underpin a potential third LNG Train from Blocks 1, 3 and 4."

Ophir Energy has oil and gas projects in eight different African countries.
