The article discusses the results of local acid treatment of key wells situated in the selected area of the deposit. This technique allows not only to recover well injection capacity, but also to increase the area sweep efficiency both according to the formation thickness and its strike, which helps to increase oil recovery.The method for effectiveness evaluation of the deposit stimulation technique has been proposed. It is based on calculation of formation system hydrodynamic characteristics with the account of well interference. Based on the geophysical well logging data (GWL), the area sweep efficiency is determined in accordance with the formation area and thickness.The proposed method has been implemented on the basis of the data of the Zhetybai (Kazakhstan) deposit.
