Exploration well B4EW6, drilled on a previously undrilled structure, has tested flows of more than 2,200 b/d on a 32/64-in. choke from the Lower Buah formation.
Tethys said the well constitutes the best flows encountered so far from the Lower Buah outside the B4EW4 area. The well is connected to the production system to undergo a long-term production test.
“B4EW6 looks similar to B4EW4. As data comes in, we will learn more, but we are hopeful it could prove as prolific as B4EW4,” said Magnus Nordin, Tethys Oil managing director.
Tethys, through wholly owned subsidiary Tethys Oil Block 3 & 4 Ltd., holds 30% interest in Blocks 3 and 4. Partners are Mitsui E&P Middle East BV with 20% and operator CC Energy Development SAL (Oman branch) with the remaining 50%.
Tethys is one of the largest onshore oil and gas concession holders in Oman.
