Abstract
In one aspect, the method comprises providing a perforating gun assembly having a first group of shaped charges on first longitudinal portion of the assembly and a second group of shaped charges on a second longitudinal portion of the assembly. The orientations of the first and second groups are rotationally offset from one another around a longitudinal axis of the perforating gun assembly. The method comprises locating the perforating gun assembly in a wellbore with the first group of shaped charges adjacent a wall of the wellbore at a perforation location, and detonating the shaped charges to form a first perforation channel in the wellbore with a defined first fracture initiation point. The perforating gun assembly is translated in the wellbore to locate the second group of shaped charges oriented towards a defined second fracture initiation point, at a desired axial position with respect to the first fracture initiation point.
