Tethys Oil has discovered another oil-bearing fault block after drilling the Farha South-17 (FS-17) well, onshore block 3 in the Sultanate of Oman.
The FS-17 was drilled as a vertical exploration/appraisal well to target the Barik formation on the Farha trend.

The well is located 1.1km east of FS-16 in a previously undrilled fault block, and was drilled to a total depth of 1,246m and encountered more than 32m of net pay in Barik.
The net pay is said to be the thickest section encountered to date along the trend, and FS-17 has been hooked up to the early production system.
In addition, four new production wells were drilled and completed in previously drilled and known oil-bearing fault blocks on the Farha South oilfield.
These include the FS-21, FS-22, FS-23 and FS-24 wells, which encountered oil and were successfully completed in the Barik section.

By GlobalDataThe four wells have been connected to the early production system.
The company said that long-term production tests are being carried out on wells from the Saiwan East oilfield on block 4 and the Farha South oilfield on block 3.
Production rates from the early production system will vary, depending on the test programme design and the transport and facility capacity.
The company said that exploration well Maha-1 was also spudded.
The well is being drilled 1.5km south-east of the Farha South-11 producing fault block, and the primary drilling target is the Barik sandstone formation at a depth of around 1,500m.
Drilling and testing operations are expected to last three to five weeks.
Tethys has a 30% stake in blocks 3 and 4, while partners Mitsui E&P Middle East holds 20% and operator CC Energy Development SAL (Oman branch) holds the remaining 50%.
