Sodium Bisulfate is an effective alternative to sulphamic acid or citric acid for lowering the pH of drilling fluids. Sodium Bisulfate comes in the form of dry (anhydrous) water-soluble, odorless granules that are white to off-white in colour.

Caustic Soda Beads (Sodium Hydroxide (NaOH)) are a strong alkali used to increase the pH and alkalinity of the liquid phase.  To obtain a given pH, the amount needed may be affected by a variety of drilling fluid products and related activities. The following chart is an approximation only. Note: Additions made to water with a …

Sulphamic Acid is a dry, non-volatile, non-hygroscopic, stable solid. It is soluble in water and forms a strongly acidic aqueous solution that is comparable in acidity to the common strong mineral acids, but it can be safely handled and stored in the dry form. Sulphamic Acid is used to reduce the pH of fluids requiring adjustment …

Sodium Bicarbonate (NaHC03) is commonly known as Bi-Carb, Baking Soda or Bicarbonate of Soda. Sodium Bicarbonate is most commonly used for treating cement contamination by precipitating the calcium as calcium carbonate and reducing the pH. The available H+ ion can reduce the pH in any drilling fluid with a pH above 8.5. As a pre-treatment …

Citric Acid is often incorporated into acid formulations. Its function is to prevent the precipitation of gelatinous ferric hydroxide as the acid spends. As a sequestering agent, citric acid can hold as much as 3000 mg/L of ferric iron in spent acid solutions for more than 4 hours at temperatures above 80°C. Citric Acid is one of the most …

Hydrated Lime or calcium hydroxide is a source of Ca and OH and is used to raise the pH. In clear water drilling, Hydrated Lime is added to the sump water to increase the pH and to provide calcium ions. In a Gyp-based mud system, Hydrated Lime is added at a concentration of 1.0 kg/m³, and then used …

Magnesium Oxide can be used as a substitute for lime as a coagulant in clear water drilling and for alkalinity control in polymer systems where a high pH (above 11.0) is undesirable. Any undissolved excess Magnesium Oxide will continue to dissolve at a slow rate to maintain a constant pH level of 10.7.
