Calcium Chloride is employed in lubricant to cool down and lubricate the bit and to get rid of cuttings from the outlet. additionally, it helps add density to the mud to beat formation pressures and keep oil, gas, and water in situ. salt inhibits clay and sedimentary rock association, adds required weight to beat formation pressure, aids in carrying cuttings to the surface, and is definitely diluted from additional targeted resolution
Calcium Chloride chemical formula CaCl2 is the ionic compound of calcium and chlorine. It is a salt that behaves as a typical ionic halide, being solid at room temperature and highly soluble in water. Common applications include brine for refrigeration plants, ice and dust control on roads, and desiccation. In the oil industry, the chemical is used in establishing and maintaining oil and gas wells. It helps well fluids gain needed consistency, increases density and stabilizes shale formations. As a completion fluid it seals well casings and displaces drilling mud. In short, Calcium Chloride is used in several applications for new or existing wells to improve efficiency and production. CaCl2 Prills are used in gas and oil drilling. It helps keep gases from forming and helps sludge from getting out of hand
Uses of Calcium Chloride
As an accelerator for concrete and as a solidifying agent in paint production
Oil-well drilling and as dehydrant in petrochemical industry
In dye production and in printing industry
Dust control and removal (coal dust, mine dust, etc.)
As a coagulant in rubber industry
As a chloridizing agent and additive in metallurgy (ferrous)
As a preservative agent for food and anti-rot treatment for wheat,fruit
Calcium Chloride use as Drilling Mud
Easier drilling activities in winter .
With Calcium Chloride Soil will become very troublesome to beat in winter, given the chilling and/or geographic location of sure mines (permafrost). calcium chloride works by cathartic heat involved with snow or ice, that helps to "soften" the soil and therefore facilitate drilling or crushing operations
Reduction of mud emissions throughout crushing activities
Crushing and stacking activities will generate a major quantity of mud, which might be harmful to the surroundings and to the health and safety of workers appointed to those tasks. To limit or maybe forestall harm, Somavrac C.C. recommends the utilization of a superior calcium chloride mud suppressant.
Waste water treatments
Calcium chloride is usually wont to management the pH scale of water, which might be necessary to cut back the toxicity of water utilized in numerous mining operations.
