Scale Dissolvers

Scale Dissolvers


M-I SWACO Production Technologies supplies a range of specialty chemicals designed to combat the many problems associated with mineral scale in oil and gas production. Our scale dissolvers are effective in dissolving sulfate and carbonate scales of barium, strontium and calcium, as well as iron scales, both downhole and in surface equipment.

Name Description
BaSOL Rapid removal of virtually insoluble barium sulphate scale (solubility 2.3 mg/L at 25°C) is assured through the deployment of BaSOL.
BaSOL2000 Rapid removal of virtually insoluble barium sulphate scale (solubility 2.3 mg/L at 25°C) is assured through the deployment of BASOL 2000.
Cal-Acid CAL-ACID has been developed to provide a viable, fast acting, non-corrosive, alternative to conventional mineral acid treatments of carbonate scales.
Cal-Acid HT CAL-ACID HT already provides a viable, fast-acting, non-corrosive, alternative to conventional mineral acid treatments of carbonate scales at temperatures of up to 100°C.
GYPSOL GYPSOL is a scale dissolver designed to remove calcium sulphate scale that usually co-precipitates with some degree of barium and/or strontium sulphate.
PYRISOL Iron sulphide scale readily forms as a corrosion product from the reaction between hydrogen sulphide and iron in steel.
R-SOL Iron and its corrosion products can present particular problems in production assemblies and process equipment.
SD-4051 SD-4051 is an EDTA (ethylenediaminetetraacetic acid) based general purpose scale dissolver designed for the removal of most mixed carbonate and sulphate scales rapidly and efficiently.
SD-4052 SD-4052 is an amine carboxylic acid based general purpose scale dissolver designed for the removal of most mixed carbonate and sulphate scales rapidly and efficiently.
