Abstract Unified Versa Fracking Device For Enhanced Recovery From Conventional Reservoirs, Hydrates, And Shales A system (100) for generating shock waves in a well bore (102) includes a versa fracking gun (110) and a coupler (112) for detachably coupling the versa fracking gun (110) to a wire line (106) from an external unit (104). The coupler (112) isolates the wire line (106) from the versa fracking gun (110). The versa fracking gun (110) includes a cartridge (200), a gas filled cylinder (202) having an internal pressure maintained below the pressure present inside the well bore (102). Further, the versa fracking gun (110) includes explosive pods provided with explosive charges to rupture the high stress concentrated regions present on the surface of the cartridge (200) and the gas filled cylinder (202) to generate shock waves. The generated shock waves are followed by negative blast waves that results in elongation of existing perforations, creation of primary and secondary fractures, and also opening of clogged pores.
