Exploration & Development — Quick Takes
Gulfsands to develop Khurbet East Butmah oil
Syrian General Petroleum Co. has granted Gulfsands Petroleum PLC permission for commercial development of the Khurbet East Triassic Butmah formation in Syria 12 miles southwest of Souedieh oil field.
The timing of development and production will depend on withdrawal of relevant European Union sanctions, Gulfsands noted.
Oil and gas volumes can be recovered within a newly designated development license area over 25 years, with a 10-year extension option. The designated area covers the same land area as that previously granted in 2008 for the development of the Khurbet East Cretaceous Massive and Triassic Kurrachine dolomite formations (OGJ Online, June 7, 2007).
Gross recoverable volumes from the Butmah are estimated at a median of 8.8 million bbl of 34° gravity oil and 62 bcf of casinghead gas at 2,850 m.
Gulfsands is operator with 50% working interest, and Emerald Energy PLC, a subsidiary of Sinochem Resources UK Ltd., has 50%.
Nutrient injection eyed in Wyoming CBM well field
The US Bureau of Land Management is seeking public comments on Patriot Energy Resources LLC's proposed Rough Draw Project 13 miles north of Gillette, Wyo., the agency's Buffalo, Wyo., field office announced on Dec. 7.
It said that BLM is preparing an environmental assessment for injection of nutrients and produced water into federal coal seams to stimulate methane gas generation in the Powder River basin.
The project would use 283 existing wells within an 18,000-acre area that already has several coalbed methane wells, BLM said. The area also includes fee and state surface ownership, with federal, fee, and state mixed mineral ownership, it indicated.
Patriot is a Gillette-based subsidiary of Luca Technologies Inc., Golden, Colo., which wants to determine the effects of its biogenic gas generation process on the coal resource in a mature CBM field producing from multiple publicly owned coals, according to the proposed project's development plan.
Comments will be accepted on the field office's scoping notice and Patriot's application and supporting documentation until Jan. 3, 2012, BLM said.
Vanco group finds oil offshore eastern Ivory Coast
A group led by Vanco Cote d'Ivoire Ltd. has a deepwater light oil discovery on Block CI-401 off eastern Ivory Coast.
Independance-1X, the group's second exploratory well on the block, went to 4,132 m in 1,689 m of water 58 miles south-southeast of Abidjan. It penetrated the targeted objective and found a series of good-quality sandstones containing light oil.
Full analysis of well results, including wireline logs, reservoir pressures, and fluid samples, confirms that the well penetrated 26 ft of hydrocarbon pay in a good-quality Turonian-aged sand package. Hydrocarbon samples indicate 40° gravity. The well will be temporarily abandoned.
Independance-1X is the group's second exploratory well on the 152,948-acre block that lies in water 950-2,100 m deep. The well is one of the deepest-water exploratory wells drilled to date in the eastern offshore Ivoirian basin.
Drilling is in progress on one more deepwater exploratory well on the block, Albacore-1X, 21 miles east of Independance-1X on a similar large Turonian deepwater slope channel stratigraphic trap.
Vanco is block operator with 28.34% participating interest. Lukoil Overseas Cote d'Ivoire Ltd. has 56.66%, and Ivory Coast's state Petroci has a 5% participating interest and 10% carried interest.
