Abstract

The development of the Pokurskaya suite of the Russkoye field is complicated by a number of factors: poorly cemented reservoir, high-viscosity oil, high lateral and vertical heterogeneity of reservoir properties, the presence of a gas cap and an underlying aquifer.

To improve the efficiency of developing the reserves of this object, hydraulic fracturing in horizontal wells is being considered.

The main goal of hydraulic fracturing operations in the Pokurskaya suite is to increase the volume of oil reserves drained by the well due to the union of additional productive intervals by the hydraulic fracture, separated by clay interlayers. Hydraulic fracturing also has the potential to improve the efficiency of low-productivity wells with a high fraction of non-reservoir along the wellbore.

Based on the results of evaluating the hydraulic fracturing technology effectiveness, the geological conditions for the applicability of hydraulic fracturing were substantiated, well completion layouts were recommended, an optimal scheme for the implementation of pilot operations was developed, candidate wells were selected, and designs of hydraulic fracturing operations were calculated.

Key words:

Hydraulic fracturing, multistage hydraulic fracturing, well completion, highly permeable reservoir, unconsolidated reservoir, pilot work
