Patent
·
OSTI ID:5315573
A sand consolidation method for controlling loose sands and the like is provided wherein the sands are formed into a hard permeable mass having improved compressive strengths and other desired properties. An acid curable resin composition is introduced into a formation containing loose sands and the like and thereafter an overflush solution is pumped into the formation, containing an acyl halide hardening agent. Contact of the resin composition with the acyl halide hardening agent causes the resin to cure or harden into an insoluble highly resistant solid material. (26 claims)
