HOUSTON, Aug. 6 -- Calvalley Petroleum Inc., operator of Block 9 in Yemen, reported that the Al Roidhat 4 appraisal well spudded July 22 encountered oil in the Upper Qishn sand formation reservoir. Initial wireline log evaluation indicates a 6.5-8.5 m oil pay in a 22 m gross oil column.
The well has been cased with 9 5/8-in. production casing, and drilling has resumed to investigate the hydrocarbon potential in the Saar, Shuqra, Kohlan, and basement formations.
After this well is completed, the rig will move to drill an initial exploration well in the recently identified South Roidhat prospect 5 km southwest of the Al Roidhat 1 discovery well (OGJ Online, July 28, 2004).
Calvalley also reported that a production test of the Auqban 1 well in the Shuqra formation reservoir by third party engineering firm Chapman Engineering Ltd indicated that, in a 59 hr test using a downhole submersible pump, the well flowed a maximum 283 b/d of oil and 41.3 Mcfd of gas from a 9.1 m net oil pay. The reservoir had an average pressure of 1,360 psi.
