Abstract
A method of use of single component resins to strengthen structural features in subterranean formations includes providing particulates, a carrier fluid, a curable resin and a latent curing agent. The curable resin is not cured by the latent curing agent at room temperature, standard pressure or neutral pH. The particulates are coated with the curable resin and the latent curing agent to create resin-coated particulates. A slurry of resin-coated particulates is created in the carrier fluid, and placed into a portion of a subterranean formation and allowing the latent curing agent to cure the curable resin to form cured, resin-coated particulates.
Claims27
A method comprising:
- providing particulates, a carrier fluid, a curable resin and a latent curing agent, wherein the curable resin is not cured by the latent curing agent at room temperature, standard pressure or neutral pH;
- coating the particulates with the curable resin and the latent curing agent to create resin and agent coated particulates;
- creating a slurry of resin and agent coated particulates in the carrier fluid;
- and
- placing the slurry into a portion of a subterranean formation and allowing the latent curing agent to cure the curable resin to form cured, resin-coated particulates.
A method comprising:
- placing a flush fluid comprising a carrier fluid, a curable resin and a latent curing agent, wherein the curable resin is not cured by the latent curing agent at room temperature, standard pressure or neutral pH, into a portion of a subterranean formation comprising particulates and allowing the curable resin and latent curing agent to coat at least a portion of the particulates;
- and
- allowing the latent curing agent to cure the curable resin on the particulate surfaces within the subterranean formation to form cured, resin-coated particulates.
A method comprising:
- introducing a fracturing fluid containing proppant into a subterranean formation at a pressure sufficient to create or enhance at least one fracture therein;
- providing a treatment fluid comprising a carrier fluid, a curable resin and a latent curing agent, wherein the curable resin is not cured by the latent curing agent at room temperature, standard pressure or neutral pH;
- introducing the treatment fluid into the at least one fracture of the subterranean formation;
- and
- allowing the latent curing agent to cure the curable resin, thereby forming a resinous proppant pack therein.
