scale-inhibitor squeeze — Oil & Gas Glossary

A type of inhibition treatment used to control or prevent scale deposition. In a scale-inhibitorsqueeze, the inhibitor is pumped into a water-producing zone. The inhibitor is attached to the formationmatrix by chemical adsorption or by temperature-activated precipitation and returns with the produced fluid at sufficiently high concentrations to avoid scale precipitation. Some chemicals used in scale-inhibitor squeezes are phosphonated carboxylic
