Calcium Chloride in Drilling Fluids

CaCl2 is used in drilling Fluids to cool and lubricate the bit and to remove cuttings from the hole. also it helps add density to the mud to overcome formation pressures and keep oil, gas, and water in place. Calcium Chloride inhibits clay and shale hydration, adds needed weight to overcome formation pressure, aids in carrying cuttings to the surface, and is easily diluted from more concentrated solution. CaCl2 additive decreases thickening time, increases ‘early strength, and shortens the time wasted at the wellsite as operators wait for cement properties to take hold. Our CaCl2 additive can be adjusted to meet specific conditions and requirements. Mixes with low concentrations decrease slurry viscosity, while mixes with higher concentrations increase slurry viscosity.
