MINIMIZATION OF RISKS OF FAILURE TO ACHIEVE THE PLANNED PRODUCTION RATE AFTER HYDRAULIC FRACTURING

 

Annotation. The article analyzes the reasons of unsuccessful geological and technical measures (GTM), in particular hydraulic reservoir fracturing (hydrofrac), on the example of oil fields of the Udmurt Republic. The ratio of the number of wells with effective hydraulic fracturing to the total number of wells, which is ≥80%, is noted. Also the reasons of failure to achieve oil flow rate after hydraulic fracturing at the studied fields have been determined, among which there are: geological, organizational, technological. It was revealed that the greatest share falls on geological reasons - 65%, a significant share of which are non-confirmation of saturation by well log survey and lithological heterogeneity. In order to solve these problems and increase the share of successful hydraulic fracturing, it is proposed to conduct additional research and develop effective criteria for selecting geological and technical measures of hydraulic fracturing. It is also recommended to carry out effective selection of wells in the dome parts of the uplifts rather than in the periphery.

Keywords: field, geological and technical measures (GTM), hydraulic fracturing, selection criteria, efficiency.
