HOUSTON, July 15 -- Tulsa-based Vintage Petroleum Inc. reported its An Nagyah No. 8 appraisal well in Yemen tested light, 43° gravity oil from the subsalt Upper Lam formation. The well, which defined the eastern limit of the An Nagyah structure, is the fourth successful well drilled in An Nagyah field this year (OGJ Online, June 4, 2004). Operator Vintage has a 75% working interest.
Vintage drilled An Nagyah 8 to 3,966 ft TD. Electric log analysis indicates a gross oil bearing interval of 43 ft. A 34 ft interval in the Upper Lam formation was perforated at 3,345-79 ft and tested at a stabilized flow rate of 607 bbl of water-free oil with a flowing tubing pressure of 63 psi.
With the addition of An Nagyah 8 and 7, which delineated the structures extension to the west, combined gross oil production capacity from the five wells exceeds 3,800 gross b/d. Initial production is targeted for later this month, as is the spudding of infill well An Nagyah No. 9.
The company also recently completed the Harmel No. 2 appraisal well near the discovery well Harmel No. 1, drilled in 2000. Harmel 2 was drilled to 2,808 ft, and cores have been obtained to aid in the assessment of the potential for development of the suprasalt heavy oil reservoirs. Completion and testing is targeted for the late third or early fourth quarter.
This year Vintage will design and construct, for $17 million, a pipeline and 10,000 b/d processing facility at An Nagyah, to be completed in second quarter 2005.
