    Caustic Soda Beads

    Caustic Soda Beads (Sodium Hydroxide (NaOH)) are a strong alkali used to increase the pH and alkalinity of the liquid phase. The amount needed to obtain a given pH 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 […]

    Citric Acid

    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

    Hydrated lime (calcium hydroxide) is a dry powder used to raise pH in various industrial applications, including clear water drilling. Hydrated lime, otherwise known as slack lime, builders lime, or pickling lime, is made from a mixture of quicklime and water. In clear water drilling, hydrated lime is added to the sump water to increase […]

    Magnesium Oxide

    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. Magnesium Oxide […]

    Sodium Bicarbonate

    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 […]

    Sodium Bisulfate

    Sodium Bisulfate is an effective alternative to sulfamic acid or citric acid for lowering the pH of…

    Sulfamic Acid

    Sulfamic Acid, otherwise known as amidosulfonic acid or amidosulfuric acid, is a dry, non-volatile, non-hygroscopic, stable solid. It is soluble in water and forms a strongly acidic aqueous solution comparable in acidity to the common strong mineral acids, but it can be safely handled and stored in its dry form. Sulfamic Acid is used to […]
