  • Publication number: 20160003015
    Abstract: A jetting gun placed in a wellbore in a formation for penetrating the formation to create perforation tunnels comprising a pressure vessel, the pressure vessel comprising a propellant chamber and a nozzle, the pressure vessel configured to withstand a pressure of the wellbore, the nozzle embedded in the pressure vessel in a predetermined orientation, such that the propellant chamber is in fluid communication with the wellbore. The propellant chamber fully enclosed within the pressure vessel configured to hold a jetting fluid and an energetic material, wherein the energetic material is operable to generate pressure within the propellant chamber when activated such that the pressure projects the jetting fluid through the nozzle to create an impact fluid to penetrate the formation to create the perforation tunnels. The jetting gun also includes a detonating mechanism configured to activate the energetic material to generate the pressure within the propellant chamber.
