Resin-in-Cement: A Hybrid Epoxy-Cement System for Enhanced Flexibility, Durability, and Long-Term Zonal Isolation in Challenging Wells
The Resin-in-Cement (RIC) system is a hybrid technology that merges thermosetting epoxy resin emulsions with traditional Portland cement systems, creating a stable emulsion for superior wellbore sealing and bond-adhesion in oil and gas wells. It solves key integrity issues like micro-annuli , and debonding in harsh downhole conditions. Conventional resin-cement mixes often fail due to density-driven separation, causing incompatibility and a non-homogeneous slurry.
