ABSTRACT:
A process and assembly for completing and providing sand control in a subterranean well and/or fracturing and preventing proppant flowback in a subterranean formation in a single trip. One or more perforating gun assemblies are juxtaposed and secured to one or more screen assemblies. Once positioned in a well adjacent a subterranean formation of interest, the explosive charges in each perforating gun assembly are detonated so as to penetrate the well and formation thereby initiating fracturing. The penetrations and the annulus defined between the well and screen assembly are then packed with gravel. Well fluid may be pressurized to in excess of the formation pressure prior to detonation of the explosive charges so as to enhance formation fracturing.
