Abstract
A system for consolidating particles in a subterranean formation includes a treatment fluid (e.g., a consolidation fluid) having a viscosity lower than 5 cP. The treatment fluid includes a resin system, a surfactant, and a curing agent. A method for consolidating particles in a subterranean formation includes preparing the treatment fluid, introducing the treatment fluid into the subterranean formation, and allowing the treatment fluid to cure to consolidate the particles in the subterranean formation.
Claims20
A system for consolidating particles in a subterranean formation, the system comprising:
- a treatment fluid having a viscosity less than 5 cP, wherein the treatment fluid, after curing via a curing agent at a temperature above 100° F., has a compressive strength greater than 1,000 lbf/in2 and up to 2,850 lbf/in2 and a retained permeability of over 75%, the treatment fluid comprising:
- a resin system;
- a surfactant having a cloud point or lower critical solution temperature (LCST) ranging from about 100° F. to about 300° F.;
- and
- the curing agent.
