Patent ID: 6851474

Claim:
In a method of forming a through-tubing vent-screen tool completion in a well bore which includes the steps of placing the tool in the well bore adjacent to a producing zone therein and then placing gravel in the well bore to form a gravel pack between the producing zone and the tool without compressive forces being exerted on the gravel pack, the improvement which prevents the loss of gravel from the gravel pack with fluids produced from the producing zone which comprises: (a) prior to placing said gravel in said well bore, coating said gravel with a hardenable resin composition comprised of a hardenable resin, a hardening agent for causing the hardenable resin to harden, a silane coupling agent, a surfactant for facilitating the coating of said hardenable resin composition on said gravel and for causing said hardenable resin composition to flow to the contact points between adjacent resin coated gravel particles, and an organic carrier liquid having a flash point above about 125° F.; (b) combining said hardenable resin composition coated gravel produced in step (a) with an aqueous carrier liquid; (c) pumping said aqueous carrier liquid containing said hardenable resin composition coated gravel into said well bore between said producing zone therein and said tool to place said hardenable resin composition coated gravel therein; and (d) allowing said hardenable resin composition on said coated gravel to harden and consolidate said gravel into a high strength permeable gravel pack which prevents the loss of gravel with produced fluids.
