Abstract
A method of avoiding a frac hit in a hydrocarbon producing field. The method comprises locating a parent wellbore in the hydrocarbon producing field, and then locating a child wellbore in the hydrocarbon producing field. The method also includes running a perforating gun assembly into the child wellbore, wherein the perforating gun assembly comprises a first perforating gun and a second perforating gun, with each defining a gun barrel housing having a first end and an opposing second end. The assembly also includes a tandem sub, with the tandem sub having first and second opposing ends defining a threaded connector, and each end having a side port configured to receive an alignment screw. The method also comprises linearly aligning charges of each of the first and second perforating guns, wherein all charges are aligned in a single direction by rotating one or both of the respective perforating guns relative to the tandem sub. The charges are aligned to fire shots into the formation at a horizontal angle and in a direction away from the parent wellbore.
