New generation of calcium sulfate scale dissolver

Halliburton HalKleen G scale removal service is a fast-acting treatment for the removal of anhydrite, gypsum, and other forms of calcium sulfate (CaSO₄) from tubing, perforations, and downhole equipment in the wellbore. The scale dissolver is a liquid solution that facilitates the rapid dissolution and removal of CaSO₄ scale or deposits with a single fluid, eliminating long soak times and extended shut-in periods required by other dissolution treatments.
