Abstract:
A method for avoiding a frac hit during a formation stimulation operation. The method includes providing a child wellbore within a hydrocarbon-producing field. The method also includes identifying a parent wellbore within the hydrocarbon-producing field. The method also includes conveying a hydraulic jetting assembly into the child wellbore on a working string. The method additionally includes setting a whipstock in the wellbore at a first casing exit location. The method then includes injecting hydraulic jetting fluid through a jetting hose and connected jetting nozzle while advancing the nozzle through against a face of the whipstock, and through a first window. The nozzle advances into the surrounding rock matrix, thereby forming a lateral borehole that extends away from the wellbore. The method also includes controlling (i) a distance of the lateral borehole from the child wellbore, (ii) a direction of the lateral borehole from the child wellbore, or (iii) both prior to hydraulic fracturing.
