Tethys Oil announces new well flow rates from Block 4 onshore

STOCKHOLM -- The appraisal program on the recently discovered structure in Block 4 onshore the Sultanate of Oman (B4EW4) continues with another very successful well. The sixth well (B4EW4-6) on the structure, flows in excess of 3,000 bopd on a 34/64 inch choke from the Lower Buah reservoir section of the Nafun carbonate group.

This is the third appraisal well into this reservoir section on the structure, and it was drilled 1,100 m northeast from the discovery well (B4EW4-1). Apart from yielding excellent flows, this well also confirmed the reservoir extension in the north eastern direction, opening up for continued appraisal drilling further away from the discovery well. The new well is being hooked up to the testing equipment for a long term production test.

The rig has moved to drill an exploration well on the nearby structure (B4EW6), with similar characteristics to the B4EW4 structure.

“We are very happy with the results from this appraisal well. The new well shows excellent flow rates and we have not yet seen where the extension of this reservoir ends. The structure has turned into a major Block 4 production area. We will shortly continue appraisal drilling, but first we hope to expand the current success with a new exploration well,” comments Tethys Oil’s managing director Magnus Nordin.

Tethys Oil, through its wholly owned subsidiary Tethys Oil Block 3 and 4 Ltd, has a 30 % interest in Blocks 3 and 4. Partners are Mitsui E&P Middle East with 20 % and the operator CC Energy Development (Oman branch) holding the remaining 50.
