Formation Stimulation by Combining Implosion Effect During Acid Injection for Optimization of Oil and Gas Filtration


Algorithm 1: preparation of surface equipment and gas-lift tree with valves connected with annulus and tubing providing leak tightness (main shut-off equipment for prevention of hydrocarbon leakage and fire hazard).

Algorithm 2: checking equipment for completeness and checking documentation of pressure test of valves to one and a half times the working pressure and to double the working pressure in case of emergency and hydrocarbons ignition.
