Re-opening the formation is one of the most important operations affecting the further efficient operation of oil and gas wells. A significant part of the work on the secondary opening of oil and gas reservoirs is currently carried out using cumulative perforation. Depending on the task at hand, as well as the well conditions and characteristics of the reservoir, cumulative, drilling or hydromechanical perforation can be used.
