An environmentally friendly scale inhibitor
- BJ Services Co., Houston, TX (United States)
This paper describes a method of inhibiting the formation of scales such as barium and strontium sulfate in low pH aqueous systems, and calcium carbonate in systems containing high concentrations of dissolved iron. The solution, chemically, involves treating the aqueous system with an inhibitor designed to replace organic-phosphonates. Typical low pH aqueous systems where the inhibitor is particularly useful are oilfield produced-water, resin bed water softeners that form scale during low pH, acid regeneration operations. Downhole applications are recommended where high concentrations of dissolved iron are present in the produced water. This new approach to inhibition replaces typical organic phosphonates and polymers with a non-toxic, biodegradable scale inhibitor that performs in harsh environments.
