摘要：
The present invention proposes a combined treatment of scale removal and inhibition in reservoir rock (inhibition squeeze), by using inhibitors derived from organophosphonic acid, in acidic medium, aiming at minimizing the intervention time in well scale mitigation operations, in addition to reducing costs per treatment and the risks associated with the process.
