Problems and methods of hydraulic fracturing in multilayered oil reservoirs with the continuous perforation

One of the most common problems during hydraulic fracturing (HF) in the oil fields of Kazakhstan is a continuous perforation of all productive layers in the section of pay zone, which subsequently causes many risks of a different nature during fracking operations and difficulties in the development of oil reserves. Despite the historical reality, which is an actual problem, there are currently attempts to do fracturing in such difficult conditions. The main complicating factor is the formation of not one long fracture, but the development of several short fractures parallel to each other. This necessitates further development of technology in order to improve the efficiency of hydraulic fracturing.
