A system and method for stimulating hydrocarbon production from a wellbore that perforates the formation around the wellbore in strategic locations so that fractures can be formed in the formation having specific orientations. The system includes deep penetration perforators that extend past a portion of the formation adjacent the wellbore having locally high internal stresses (a stress cage); and big hole perforators that form perforations with a larger entrance diameter. The perforators form perforations in the formation that are axially consolidated along the wellbore. After perforating, the wellbore is hydraulically fractured with high pressure fluid, which creates fractures in a formation surrounding the wellbore that extend radially outward from the perforations. Creating perforations that are axially consolidated reduces the chances of forming competing fractures in the formation during fracturing.
