Abstract
A method for performing a downhole perforating and fracturing operation from a wellbore (12) positioned within a subterranean formation (18). The method includes locating a perforating gun string (24) within the wellbore (12), detonating a first perforating gun (28) to create a first discrete fracture initiation site (42) in the formation (18), repositioning the perforating gun string (24) within the wellbore (12) and detonating a second perforating gun (30) to create a second discrete fracture initiation site (44) in the formation (18). Thereafter, the method also includes pumping a fracture fluid into the wellbore (12) and propagating a single dominant planar fracture (56, 58) from each of the discrete fracture initiation sites (42, 44).
