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 method for consolidating particles in a subterranean formation, comprising:
- preparing a treatment fluid comprising:
- a resin system;
- a surfactant;
- and
- a curing agent;
- introducing the treatment fluid into the subterranean formation;
- and
- allowing the treatment fluid to cure the consolidating particles in the subterranean formation, wherein the treatment fluid, after curing via the curing agent at a temperature above about 100° F., has a compressive strength greater than about 1,000 lbf/in2 and a retained permeability of over about 75%.
