Scale Inhibitors

Scale occurs because the minerals in produced water exceed their saturation limit as temperatures and pressures change. Scale can vary in appearance from hard crystalline material to soft, friable material and the deposits can contain other minerals and impurities such as paraffin, salt and iron. Scale inhibitors are used to prevent these deposits from forming.

Phosphate Esters

Alpha 2003 and Alpha 2004 – are concentrated 95- to 100-percent active alkyl-nonylphenol-phosphate-ester-acid anionic surfactants with multifunctional abilities. They can be formulated to perform as an emulsifier, wetting agent, antifoulant, cleaner, or detergent. These products can be used in foam and air-mist drilling systems without offsetting drilling fluid properties.

Alpha 2401 – is a 40- to 45-percent active bishexamethylenetriamine pentamethylene phosphonic acid
sodium salt concentrate used to formulate scale preventives for treatment of calcium carbonate, calcium, barium, and strontium sulfate.

Alpha 2240 – is a 70- to 80-percent active hydroxyamino phosphate ester concentrate used to formulate scale preventives for squeeze or continuous treatment of calcium carbonate, calcium, barium, and strontium sulfate.

Alpha 2240-70 – is a 57- to 61-percent active hydroxyamino phosphate ester concentrate used to formulate scale preventives for squeeze or continuous treatment of calcium carbonate, calcium, barium, and strontium sulfate.

Alpha 2247 is a 63- to 67-percent active hydroxyamino phosphate ester sodium salt concentrate used to formulate scale preventives for treatment of calcium carbonate, calcium, barium, and strontium sulfate.

Alpha 2290 – is a 90- to 100-percent active alkyl phosphate ester acid corrosion preventive used in water-based drilling systems.

Phosphonates and Phosphonic Acids

Alpha 2408 - is a 35- to 45-percent active sodium salt of a modified diamine phosphonate concentrate used to formulate scale preventives.

Alpha 2801 - is a 48- to 52-percent active bishexamethylenetriamine pentamethylene phosphonic acid used as a concentrate for treating calcium and magnesium carbonate, calcium, barium, and strontium sulfate.

Alpha 2803 – is a 48- to 52-percent active diethylenetriamine pentamethylene phosphonic acid to formulate scale preventives for treatment of calcium and magnesium carbonate, calcium sulfate, and barium scales.

Alpha 2807 - is a 48- to 52-percent active concentrate of phosphonate and ether diamines, triamines, and tetramines used to formulate scale preventives for treating calcium and magnesium carbonate, calcium, barium, strontium sulfate, and iron scales.

Alpha 2867 - is a 38- to 42-percent active ammonium salt of ether diamine, triamine, and tetramine phosphonate, used to formulate scale preventives for treatment of calcium and magnesium carbonate, calcium, barium, strontium sulfate, and iron scales.

Polymers

Alpha 2771 - 50 to 55% active sodium salt of complex polyacrylate designed as a scale inhibitor for calcium and magnesium carbonate, calcium, barium and strontium sulfate, and iron scales in water systems. Also functions as a dispersant and sludge conditioner in boilers. Can be diluted with water or water and antifreeze agents before use for ease of handling.

J-Poly 101A - 50% active polyacrylate scale inhibitor. Effective against calcium carbonate, calcium sulfate, and certain iron scales. Stable at high temperatures and is slightly acidic (pH 3-4).

Scale Clear®

ScaleClear® A100 - is a liquid blend containing both organic and mineral acids, corrosion inhibitors, and amphoteric surfactants used to dissolve carbonate, iron-sulfide, and iron-oxide scales.

ScaleClear® CSP - is a solid controlled-release scale preventive containing three formulations of fused
sodium-calcium phosphate glass, each with a guaranteed minimum phosphorus pentoxide content of 68 percent, designed for treatment of calcium carbonate, calcium, barium, and strontium sulfate.

NaCl Inhibitors

Na-Minus® 55 - Liquid formulation of imido polyalkyl amides used to inhibit precipitation of sodium chloride salt from high chloride brines. Allows treatment fluids to carry very high salt saturations up to 40%. Generally, 5% by volume of fresh water is recommended for batch treatments. For continuous treatment, 250 to 1000 ppm (parts per million) neat chemical should be added to the brine.

Na-Minus® - Liquid formulation of amino acid amides that controls salt deposition over the wide temperature and pressure ranges encountered from the bottom of the hole to the surface in producing wells. Dosage requirements will vary with brine, temperature changes, solids concentration, pH and equilibrium time. For continuous treatment, 250 to 1000 ppm (parts per million) neat chemical should be added to the brine.
