Field experience of chemical IOR/EOR at Permian-Carboniferous deposit of Usinsk oilfield
This article presents the field experience of using chemical methods to improved/enhanced oil recovery (IOR/EOR) for the extraction of high-viscosity oil from a fractured reservoir, including in conjunction with thermal methods, i.e. steam injection. The results of pilot tests for 2016–2018 on Permian-Carboniferous deposits of high-viscosity oil at Usinsk oilfield of LLC LUKOIL-Komi are discussed. The tests were carried out by Institute of Petroleum Chemistry of the Siberian Branch of the Russian Academy of Sciences, together with PermNIPIneft, branch of LLC LUKOIL-Engineering, and OSK Company. Several types of work were carried out at various wells, including blocking the water inflow for hot producing wells, various types of treatment for hot injection wells, including horizontal ones. The use of chemical compositions together with cyclic steam stimulation (CSS) is discussed. The results of treatment of cold wells not covered by thermal effects are also presented. Technologies using thermotropic gel-forming and oil-displacing compositions have shown their effectiveness in field conditions and have been recommended for industrial implementation.This article presents the field experience of using chemical methods to improved/enhanced oil recovery (IOR/EOR) for the extraction of high-viscosity oil from a fractured reservoir, including in conjunction with thermal methods, i.e. steam injection.
