PRODUCT INFORMATION

Acetic Acid
A mild organic acid, acetic acid (C2H4O2) is used to lower the pH level in clear brine completion fluids. Acetic acid is less corrosive than strong mineral acids.

Buff-10
An alkaline material, Buff-10 is used to establish alkalinity and resist pH changes up to a pH level of 10 in fresh water or brine systems.

Buff-6
An organic carboxylic acid, Buff-6 is used to buffer pH to a moderately acidic level.

Caustic Potash
A strong mineral base, caustic potash (potassium hydroxide, KOH) is used to increase pH levels in potassium based clear brine fluids.

Caustic Soda
A strong alkaline (base) compound, caustic soda (sodium hydroxide, NaOH) is used to control the alkalinity in sodium based clear brine fluids.

Citric Acid
A mild organic acid with strong metal complexing capabilities, citric acid (C6H8O7) is used predominately in sodium and potassium based clear brine fluids to increase the pH level. Citric acid is less corrosive than strong mineral acids.

Hydrochloric Acid
A strong mineral acid, hydrochloric acid (HCl), is used to decrease the pH level in halide based clear brine fluids and to degrade calcium carbonates.

Lime
A mild mineral base, lime (Ca(OH)2) is used to increase the pH level in calcium based clear brine fluids.

Magnesium Oxide
A strong alkaline earth base, magnesium oxide (MgO), is capable of increasing the pH level up to 10.0 in sodium/potassium based halide and formate clear brine fluids as well as calcium based halide clear brine fluids.

Soda Ash
A high, purity base, soda ash (sodium carbonate, Na2CO3) is used as a chemical precipitant for calcium in sodium based brine fluids. Soda ash reacts with available calcium to form calcium carbonate, which is then removed through filtration. Large amounts of soda ash can increase pH levels.
