Abstract
A method of controlling the migration of fines in a subterranean formation comprising contacting the formation with a dilute resin solution; displacing the resin solution into the formation, preferably with an overflush oil, so as to leave behind a thin film of resin solution; extracting the diluent present in the resin, and then curing the resin to an infusible state. The preferred resin is a one-step phenolic type resin which cures at formation temperatures and which should comprise from about 5 to about 30 weight percent of the resin solution and preferably about 10 to 20 weight percent.
