ABSTRACT:
Voids in a gravel pack, particularly in deviated wellbores, are substantially eliminated via a process which utilizes a high energy impulse device. Said device is lowered into the vicinity of the voids and detonated thereby causing turbulence through the screen or slotted liner which causes a re-adjustment of the pack. Energy from said device can be tailored to allow considerable agitation to the gravel pack and screen without destroying said screen.
