Calcium Chloride

Description of product

Calcium Chloride is a versatile inorganic compound widely used in the oil and gas industry. It is highly soluble in water and exhibits hygroscopic properties, making it an essential component for drilling, completion, and workover operations. Calcium Chloride is primarily used as a brine additive to adjust density and control formation pressures while ensuring compatibility with reservoir fluids.

Applications:

  • Drilling Fluids:Enhances fluid density to control formation pressures.
    • Acts as a shale stabilizer by inhibiting clay swelling.
  • Completion Fluids:Used to prepare high-density clear brines for maintaining wellbore stability.
  • Cementing Operations:Speeds up cement setting time in certain formulations.
  • Dehydration:Effective as a desiccant to remove moisture from natural gas and crude oil.
