ABSTRACT:
This specification discloses a method of completing a cased well that penetrates a subterranean formation to control the production of sand from the formation. The well is provided with perforation tunnels that extend through the casing and communicate with the formation. Removable plugs are formed in the perforation tunnels and thereafter a gravel pack is formed and consolidated in the well within the casing adjacent the perforation tunnels. Thereafter the removable plugs are removed from the perforation tunnels to provide unobstructed tunnels for the flow of fluids from the formation into the well. The formation adjacent the perforation tunnels may also be consolidated to mitigate the movement of sand from the formation into the perforation tunnels.
