Development of technologies of horizontal and multilateral wells completion in LUKOIL-West Siberia LLC

UDK: УДК 622.245.723
Key words: multilateral wells, well completion
Authors: M.M. Fattakhov, D.L. Bakirov, V.A. Burdyga, E.V. Babushkin, A.Yu. Sentsov, I.S. Sokolov, O.A. Yarmolenko (KogalymNIPIneft Branch of LUKOIL-Engineering LLC in Tyumen, RF, Tyumen), V.N. Kovalev (LUKOIL-West Siberia LLC, RF, Kogalym)

The history of formation and modern advances in the area of technology of completion of multilateral horizontal and horizontal wells in the fields of LUKOIL-Western Siberia OOO is presented. By mid-2016 more than 40 horizontal wells were drilled with use of depression equipment, more than 70 wells - on the lightweight drilling fluids with density of 920-1040 kg/m3, more than 150 multilateral wells are put into operation. The experience of the construction of horizontal wells with carrying out 10-15-stage fracturing is considered. Such multilateral wells completion methods are described as the inclusion of an oil-swellable packers, separating lateral outlets, to the tail filter packaging arrangement; application of active circulation valves and swellable packers combined with the bypass system for downhole pumping equipment in packaging arrangement; carrying out multistage fracturing. Currently these variants of multilateral wells completion are introduced on a small scale, but their use is planned to expand in prospect. It was noted that the development of multilateral wells completion technologies is a significant focus area in the area of increase of efficiency of LUKOIL-Western Siberia OOO fields digging. For large-scale realization of the presented solutions it is necessary to test and implement of national technical means in order to increase the investment attractiveness of projects on production of hard-to-recover hydrocarbon reserves.
