Some specific features of Ach6 site development of imilorskoye deposit using the technologies of a multi-stage hydraulic fracturing of a formation (MSHFF). Problems and technology solutions
Based on the successful experience of carrying out a two-stage hydraulic fracturing of formations (HFF) at various fields of LLC "LUKOIL-Western Siberia" and the theory of fracture reorientation during the repeated HFF, the idea of increasing the number of stages per an exposure interval has been proposed. The principle of the proposed technology to be implemented at Аch6 site lies in alternately carrying out of two- and three-stage hydraulic fracturing of a formation for each interval of impact of the wellbore horizontal part, thus allowing to get a network of cracks in aggregate and thereby multiply increase the coverage and the area of drainage. The results of the first well operation showed that this method of impact on the formation has a significantly greater potential relative to standard fracturing approaches.
