ADDITIVE TO FLEXIBILIZE EPOXY-BASED RESINS FOR USE IN OIL FIELD APPLICATIONS

摘要

The present invention provides an oil and gas well treatment comprising (a) preparing a composition by mixing an epoxy-based resin, an alkylphenol-blocked isocyanate, and a polyamine, (b) introducing the composition into a wellbore, (c) reacting the composition to produce a solid product, wherein the solid product reduces or prevents ingress of formation water into the oil and gas well. The inventive methods may find use in a variety of applications where increased flexibility, resilience, and adhesion are desired or required.
