RESIN COMPOSITION, INJECTION MATERIAL AND PACKING METHOD
First Claim
1. A resin composition used for forming surface layers coating at least a part of outer surfaces of particles, the particles adapted to be packed in fractures formed in a subterranean formation, comprising:
- an acid curing agent having an acidic group;
an acid curable resin to be cured in the presence of an acid; and
a polyester,wherein the acid curing agent exists in a state that the acidic group thereof is blocked by a compound having reactivity with the acidic group.

Abstract
A resin composition of the present invention is used for forming surface layers coating at least a part of outer surfaces of particles, the particles adapted to be packed in fractures formed in a subterranean formation. The resin composition contains an acid curing agent having an acidic group, an acid curable resin to be cured in the presence of an acid, and a polyester. The acid curing agent exists in a state that the acidic group thereof is blocked by a compound having reactivity with the acidic group. This makes it possible to provide a resin composition which can reliably cure an acid curable resin at a required place, an injection material containing such a resin composition and particles, and a packing method for packing such particles in the fractures formed in the subterranean formation.
