Lukoil opens six deposits in 2011
MOSCOW. May 29 (Interfax) - Russian oil major Lukoil opened six deposits last year: Vostochno-Lambeishorskoye in the Republic of Komi, Nikulinskoye in Perm Territory, Yuzhno-Eityanskoye in Western Siberia, Yuzhno-Stanovoye and Yurevskoye in Volgograd Region, Independence in Cote d'Ivoire, and twenty new oil layers at deposits under development, the company's annual report says.
Two wells drilled at Vostochno-Lambeishorskoye confirmed the presence of industrial oil strata. Open-shaft testing produced a flow of pure light oil of up to 6,300 barrels per day. The deposit contains recoverable C1+C2 reserves of 21.9 million tonnes and 3P reserves of 53 million barrels. Yurevskoye deposit C1+C2 reserves amount to 1 million tonnes and Yuzhno-Stanovoye reserves to 632,000 tonnes.
The building of two wells in Caspian Sea waters was completed last year and both are productive. Exploratory-prospecting drilling was 100% successful. The building of 1650-meter-deep well #8 Rakshechnaya produced industrial oil flow during testing of the Neocomian layer of a maximum of 2,969 barrels per day. And the Aptian layer was tested for the intensification of flow with the first maritime hydrofracking. Top flow there was 28 barrels per day prior to hydrofracking and 282 barrels afterwords. In additional the drilling of well #2 was completed at the Sarmatian layer (3330 meters). Drilling confirmed the strata's productivity and revealed an expansion of the gas-containing contour, and testing was down at the production tower at three productive Tithonian horizons. Combined testing of stratas II and III produced a gas flow of 400,000 cubic meters per day and condensate flow of 618 daily barrels. Testing of strata I produced gas flow of 1.094 million cubic meters per day and condensate flow of 209 barrels per day. C1 natural gas reserves at the Sarmatian deposit increased 55.6 billion cubic meters (bcm).
In the context of the development of the Permian-Carbonian layer at the Usinskoye deposit in Republic of Komi this year and experiment is planned to test out perpendicular thermogravitational drainage of the strata. It was put into production in 1977. As of the first of this year, proven reserves in this strata were 430 million barrels per SEC standards (3P reserves - 680 million barrels). The layer features a highly non-uniform carbonate collector layer containing very viscous oil and requiring thermal development methods.
