Drilling Fluid Additive

Where To Use

Onshore and offshore oil and gas producers rely on custom-formulated clear brine fluids containing calcium chloride. These fluids, used in all types of drilling and completion applications, reduce water activity and, create osmotic forces to prevent shales from absorbing water in oilfield completion and workover operations. The brine’s divalent calcium ion inhibits clay swelling, dispersion, and migration. Water containing high concentrations of calcium chloride can be used as a kill fluid in production wells, especially those containing heavy concentrations of carbon dioxide.
