Study of geological and technological factors on the efficiency of hydraulic fracturing

Abstract

Using correlation analysis, the authors assess the impact of geological and physical, geological and technological properties on the technological effect in the development of fields using hydraulic fracturing. The dependence of technological effect of hydraulic fracturing from the quality of casing string annulus fixing is also considered. The analysis of technological efficiency of regular technology of hydraulic fracturing in conditions of JSC TATNEFT showed its insufficient level due to the lack of methods which take into account the impact of geological and physical, geological and technological factors. The study of correlation relationship between field results of hydraulic fracturing and reservoir properties established quantitative geological field criteria for its effective use, which allowed to make a more informed choice of objects of impact.
