Annotation:
Hydraulic fracturing is one the main enhanced oil recovery methods applicable for reservoirs with hard-to-recover reserves and low porosity and permeability values. However, conventional hydraulic fracturing on the objects with complex geological structure possibly won’t achieve planned process performances of well operation. Thus, there occurs the necessity of looking for optimal solutions for hydraulic fracturing technology modernization which will meet the requirements of economic and process efficiency.
One of the criteria limiting hydraulic fracturing application is close proximity of water-saturated and gas-saturated formations which are separated by thin clayish barriers. However, application of lightweight and ultra-lightweight proppants can significantly expand the possibilities of hydraulic fracturing. The purpose of this technology includes control over the altitude of fracture vertical propagation, decrease of water-flooding risk, exclusion of associated fluid volumes, effective embedment of proppant in reservoir productive zone and increase of oil recovery efficiency due to involvement of remote and non-draining reserves. Unique feature of this technology lies in the usage of low-viscous liquid during fracturing.
The authors of the article present the results of analytical calculations made for determining impact of various types of process fluid and proppants on hydraulic fracturing efficiency. It was revealed that various types of hydraulic fracturing liquids differently influence the conductivity of a proppant pack or fracture.
The basic principles of the objects determination appropriate for the technology of fracture altitude control during hydraulic fracturing are considered as well. The results of hydraulic fracturing process simulation using high-viscous fluids with conventional proppant and low-viscous fluids with lightweight proppant in RN-GRID simulator medium which takes into account the application of high-viscosity fluids with conventional proppant and low-viscosity fluids with lightweight proppant are also given.
The parameters obtained at the mini-hydraulic fracturing stage were statistically analyzed in order to determine hydraulic fracturing application criteria using lightweight proppants. Based on these results, boundary conditions for conducting hydraulic fracturing using lightweight and ultra-lightweight proppants were established which allows avoiding complications at the stage of this technology practical application.
