Tethys: Farha South-4 Well Completed in Oman
The Farha South-4 well (FS-4) in Block 3 onshore the Sultanate of Oman has been completed. The pilot hole was drilled to a depth of 2,039 meters. Both the Barik and the Lower Al Bashir formations were penetrated with oil shows. A horizontal section of 820 meters was drilled in the Barik formation. 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 barrels per day 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 meters 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 meters below ground level. The exploration objective in the Miqrat was drilled without any significant oil shows. A 820 meter 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 kilometers northeast of FS-3.
Tethys has a 30 percent interest in Blocks 3 and 4. Partners are Mitsui E&P Middle East B.V. with 20 percent and the operator CC Energy Development S.A.L. (Oman branch) holding the remaining 50 percent.
