The well, located about 20km west of the Saiwan East Oilfield, targets five potential reservoir formations, in which four are proved as hydrocarbon-bearing reservoirs in other locations in Oman.

It is planned to be drilled to a total depth of 3,300m and focuses the Lower al Bashir, Miqrat, Amin, Buah and Masirah Bay formations.

The Lower al Bashir sandstone formation is in production on Block 3, the company said.

Other three formations, including the Miqrat and Amin sandstone formations and the Buah carbonate formation have proved as hydrocarbon bearing, which are in production on other locations in Oman.

The Masirah Bay sandstone formation, however, has never been proven.

Tethys Oil , through its wholly-owned subsidiary Tethys Oil Block 3 and 4, own a 30% interest in the Blocks 3 and 4, while the operator CC Energy Development Oman branch owns 50% and Mitsui E&P Middle East with 20% hold the remaining interests in the project respectively.

Tethys Oil mainly focuses on identification and development for production of oil and natural gas assets.

In Sultanate of Oman, the company is the second largest onshore oil and gas concession-holder with licence interests in three onshore blocks.
