Gelled-acid systems based on the gelation of hydrochloric acid (HCl) are used extensively in both matrix and fracture acidizing to prevent acidizing-fluid leakoff. However, these systems can lead to formation damage. To mitigate this risk, the authors have developed a self-breaking, formation-damage-free, novel nanoparticle-based gelled-acid system to replace polymer-based gelled-acid systems.
Nanoparticle-Based Gelled-Acid System
The complete paper showcases a method for gelling up an acid formulation for stimulating a carbonate reservoir. The technique is based on surface-modified nanoparticles.
