A method for performing a downhole perforating and fracturing operation from a wellbore () positioned within a subterranean formation (). The method includes locating a perforating gun string () within the wellbore (), detonating a first perforating gun () to create a first discrete fracture initiation site () in the formation (), repositioning the perforating gun string () within the wellbore () and detonating a second perforating gun () to create a second discrete fracture initiation site () in the formation (). Thereafter, the method also includes pumping a fracture fluid into the wellbore () and propagating a single dominant planar fracture () from each of the discrete fracture initiation sites ().
