The paper presents the numerical reservoir model constructed to study the influence of hydraulic fracturing on the effective oil recovery. The work of neighboring development wells is also addressed. The paper seeks to examine the way hydraulic fracturing in a development well affects the degree of recovery from the whole pool of the field. To solve this problem, the oil pool model developed by waterflooding is being considered. The paper examines the efficiency of hydraulic fracturing employed in wells at different locations. The study found that well stimulation technique affects the performance of near wells where there is an increase in the water cut of the production and a decrease in the oil rate.
