Vegas Oil & Gas SA and TransGlobe Energy Corp. have a Cretaceous oil and Jurassic gas-condensate discovery on the 50-50-held, 102,000-acre East Ghazalot block in the Abu Gharadig basin in Egypt’s Western Desert.
The North Dabaa-1X exploratory well was drilled to a total depth of 14,740 ft and cased. Based on open hole well logs and samples, the well encountered 8 ft of net oil pay in the Cretaceous Abu Roash formation and 23 ft of net gas-condensate pay in the Jurassic Khatatba formation.
A 72.5-hr flow test of Khatatba at 9,882-9,906 ft recovered 48.9 MMcf of gas and 4,893 bbl of 56.9° gravity condensate on 18/64-in. to 64/64-in. chokes with corresponding wellhead drawdowns of 2% to 44%. This represents average rates during the entire flow test of 16.2 MMcfd and 1,620 b/d.
An extended flow period of 26 hr on a 64/64-in. choke resulted in rates of 26 MMcfd and 2,571 b/d. Shut-in periods were interspersed, but no detailed well test analysis has been performed. The test results are not necessarily indicative of long-term performance, TransGlobe said.
The Jurassic new pool discovery will require more drilling to determine the extent and commerciality, and the Abu Roash oil zone will be completed and production-tested at a future date.
The well was drilled, cased, completed, and tested for an estimated $6.6 million.
The North Dabaa-1X discovery is 1.4 km east of the TransGlobe’s newly awarded 100% working interest South Ghazalat concession which is awaiting government ratification.
