ABSTRACT:
A method of completing a sandy production zone located downhole in a borehole by spotting a polymeric agent adjacent to the production zone, perforating the casing adjacent to the zone, and simultaneously increasing the pressure on the agent to a value which exceeds the formation pressure so that the polymeric agent is forced back up into the perforations as they are formed by the hot jets issuing from the gun.
The polymeric agent is allowed to "set up" into a porous self-supporting mass, the pressure on the agent is reduced, and the well produced with flow of the production occurring through the porous mass.
