Farha South well completed in Oman

Exploration & Production

The Farha South-4 well (FS-4) in Block 3 onshore the Sultanate of Oman has been completed, Tethys Oil has announced. The pilot hole was drilled to a depth of 2,039 m. Both the Barik and the Lower Al Bashir formations were penetrated with oil shows. A horizontal section of 820 m was drilled in the Barik formation and a pump was installed and production testing was conducted on the horizontal section.

The maximum rate achieved with pump during the tests was 3,079 bpd of 43 API gravity oil through a 80/64ths (31.75 mm.) choke size. FS-4 will now be connected to the Farha South Early Production System for a long term production test.
The FS-4 well spudded in mid-August and was drilled 740 m to the south southeast of the Farha South-3 well. Both the Barik and the Lower Al Bashir formations were penetrated with oil shows. Electrical logs were run over these sections, but no testing was conducted in the vertical pilot hole. Two cores from the Barik formation and one core from the Lower Al Bashir formation were extracted. The Barik formation was found at 1,272 m below ground level. The exploration objective in the Miqrat was drilled without any significant oil shows. A 820 m horizontal section was drilled in the Barik formation which was logged during drilling.
The rig has been moved to drill the Farha South-5 (FS-5) well, which is being drilled as a stepout exploration well. The FS-5 well is located 6.8 km northeast of FS-3. Tethys has a 30 per cent interest in Blocks 3 and 4. Partners are Mitsui E&P Middle East B.V. with 20 per cent and the operator CC Energy Development S.A.L. (Oman branch) holding the remaining 50 per cent.
