Calcium Hydroxide (Lime)

Calcium Hydroxide, commonly known as hydrated lime, is a widely available and cost-effective commercial chemical. It is frequently used as a source of calcium ions (Ca²⁺) and hydroxide ions (OH⁻) in water- and oil-based drilling fluid systems. Due to its strong pH control, alkalinity enhancement, and buffering capacity, it plays a critical role in managing chemical reactions and stabilizing deep well drilling environments.

Product Features:

• Economical source of calcium

• Controls pH and increases alkalinity

• Helps reduce corrosion from acidic gases such as H₂S or CO₂

• Used in bentonite mud systems to promote flocculation

• Precipitates water-soluble carbonate ions

• Activates fatty-based mud additives

• Improved solubility in high-salinity water

Industrial Applications:

• Oil and gas drilling industry

  • Used in oil-based and water-based drilling muds to lubricate drill bits and maintain borehole stability

  • Acts as a buffer to control pH, reducing the risk of equipment and formation corrosion

• Bentonite-based drilling mud systems

  • Enhances flocculation of bentonite, improving hole-cleaning performance

• Gypsum mud systems

  • Maintains an alkaline environment to protect materials and drilling tools from corrosion
