Arcasolve powdered HT starch breaker enzyme is a dry enzyme product that readily dissolves in fresh water, seawater or completion brine with other breaker chemicals to produce ORCA for WBM combined acidizing and polymer breaker fluids. These formulations are used to remove drilling mud damage in oil and gas producing and injection wells. They are particularly helpful to clean open hole horizontal/directional wells including slotted liner, screen or gravel pack completions. It is starch breaker enzyme typically used in wells with a BHT in the range 20˚C - 130˚C. It is also compatible with other polymer breaker enzymes to treat mud cake damage where more than one type of polymer is present.
