Abstract: A method includes simultaneously injecting a chemical agent, through an injector, into a perforated wellbore section of a well in a hydrocarbon reservoir, and generating an acoustic wave with an acoustic tool in the wellbore section. The injector and acoustic tool are moved to and fro in synchronization. The acoustic tool includes at least one of a sonotrode and a shock wave tool. A down-hole tool assembly comprises the injector, the acoustic tool, and a movable cable hose connected to the injector and the acoustic tool for moving the injector and acoustic tool to and fro in synchronization. The cable hose comprises a wire for supplying power to the acoustic tool and having a conduit for supplying the chemical agent to the injector.
