Several wells in the Prudhoe Bay field have been damaged by the deposition of calcium carbonate scale in the perforation tunnels and the near-well-bore formation sandstone. Inhibitor squeeze treatments have successfully prevented this scale damage and the capacity loss resulting from it. Wells, which had monthly decline rates greater than 10% prior to treatment, have maintained their maximum capacity for over a year. In some wells, treatment lives greater than 2 yr have been obtained. This work summarizes the laboratory design and field implementation of inhibitor squeeze treatments at the Prudhoe Bay field. The history, mechanisms, and extent of the formation damage problem are reviewed; the laboratory and field tests used to screen inhibitors and to design the squeeze treatments are detailed; and the history and success of the treatments in the field are discussed.
