The sixth well (B4EW4-6) of an appraisal program in Block 4 onshore Oman (B4EW4) has yielded flow rates in excess of 3,000 b/d on a 34/64-in choke from the Lower Buah reservoir section of the Nafun carbonate group, Tethys Oil said in a news release.
This is the third appraisal well into this reservoir section on the structure, and it was drilled approximately 1,100 m (3,609 ft) northeast from the discovery well (B4EW4-1). This well also confirmed the reservoir extension in the northeastern direction, opening up for continued appraisal drilling further away from the discovery well, the release said. 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.
Tethys Oil AB, 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 B.V. with 20% and the operator CC Energy Development S.A.L. (Oman branch) holding the remaining 50%.
