ABSTRACT:
A method of preventing the failure of a sand consolidation treatment due to contamination of the resinous material with aqueous rathole fluids during injection is described. The method involves displacing the aqueous rathole fluids with a dense, nonaqueous liquid prior to introducing the resinous material into the formation.
