Document Type and Number:
WIPO Patent Application WO/2015/012320
Kind Code:
A1
Abstract:
This resin composition is used in order to form surface layers which coat at least portions of outer surfaces of particles used to fill fractures formed in a subterranean layer, and includes: an acid curing agent provided with acidic groups; an acid curable resin which cures in the presence of an acid; and polyester. The acid curing agent is present in a state in which the acidic groups therein are blocked by a compound exhibiting reactivity with the acidic groups. As a result, a resin composition with which an acid curable resin can be reliably cured in a desired place, an injection agent including said resin composition and particles, and a filling method using said particles to fill fractures formed underground can be provided.
