A method of treating a subterranean formation, comprising:
- placing a composition into a subterranean formation, the composition comprising a plurality of capsules each independently comprising an outer wall and an inner compartment, the inner compartment independently comprising at least one of a first hardenable resin, a first hardener or activator, or a solvent;
- and
- forming a self-healing hardened resin in the subterranean formation from the composition.
A method of treating a subterranean formation, the method comprising:
- placing a composition into a subterranean formation, the composition comprising:
- a plurality of capsules having a diameter of about 0.1 micron to about 10 mm and each independently comprising an outer wall and an inner compartment, the inner compartment independently comprising at least one of a first hardenable resin, a first hardener or activator, or a solvent;
- and
- a material outside the outer wall of the plurality of capsules comprising at least one of a second hardenable resin, a second hardener, or a second activator, wherein at least one of:
- the composition comprises the second hardenable resin and the inner compartment comprises the first hardener, the first activator, or a combination thereof,
- the composition comprises the second hardenable resin and the inner compartment comprises the first hardener, the first activator, or a combination thereof, or
- the composition comprises the second hardenable resin and the inner compartment comprises the first solvent;
- and
- forming a self-healing hardened resin in the subterranean formation from the composition.
A self-healing hardened resin for treatment of a subterranean formation, comprising:
- a hardened resin;
- and
- a plurality of capsules each independently comprising an outer wall and an inner compartment, the inner compartment independently comprising at least one of a first hardenable resin, a first hardener or activator, or a solvent.
