Mud Acid Effect on Fines Migration Problem Using a Newly Developed Al/Zr-Based Clay Stabilizer (A): Mitigation Can Happen
Abstract: Sandstone reservoirs exhibit severe fines migration problems subsequent to conventional mud acid (HCl: HF) treatments. The acid treatment proved to be effective for a relatively short period of time, with a sudden production decline owing to either that mud acid spent rapidly in close proximity to the wellbore, causing clays to migrate into the acidized area and re-plug the formation; or that the mud acid system actually weakens the structure …
