    Calcium chloride application
    1. Calcium Chloride for Oil & Gas Drilling
    Calcium Chloride 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. Calcium Chloride Prills are used in gas and oil drilling. It helps keep gases from forming and helps sludge from getting out of hand.
    Drilling Muds:
    Calcium Chloride is used in drilling mud to cool and lubricate the bit and to remove cuttings from the hole. Calcium Chloride 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.
    Completion Fluids:
    Calcium Chloride is used as a completion fluid just before the producing formation is reached to flush the hole clean of solids so the casing can be cemented into place. As a clear, solids free brine, Calcium Chloride is ideal as a completion fluid with a density range of 10 to 12 pounds per gallon.
    Concrete Accelerator:
    As a pipe that runs from the reservoir to the surface, the casing is usually cemented into place to ensure a pressure tight connection to the oil and gas reservoir. The concrete also prevents caving, confines production to the well bore, and provides a way to control well pressure. Calcium Chloride dramatically cuts set time for the concrete and can be used down-hole to several thousand feet.
    Packer Fluid:
    Once the casing is cemented into place, a smaller diameter pipe, the tubing, is inserted into the casing. Tubing makes the flow of oil or gas more efficient and can be replaced if plugs develop or it is damaged. Tubing is used with a packer fluid that keeps the well fluids away from the casing to minimize corrosion. The tubing packer combination reduces well pressure on the casing and reduces the chance that a casing leak could become a blowout. Calcium Chloride is used in packing the annular space between the tubing and the casing. It helps maintain pressure levels because it has sufficient density to offset the pressure on the casing.
    Workover Fluid:
    Calcium Chloride is used as a workover fluid, flushing wells free of solids before they are repaired or before reworking a well that has been idle for some time.
    Onshore and offshore oil and gas producers rely heavily on custom-formulated clear brine fluids containing calcium chloride for all types of drilling and completion applications. These fluids are used in oilfield completion and workover operations to reduce water activity and create osmotic forces to prevent absorption of water by shales. The 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.
    2.Water Treatment
    Calcium chloride is used in waste water treatment applications to remove undesired impurities. The petroleum, metal working, laundry, textile and food processing industries add calcium chloride to oily waste streams to cause oil droplets to float to the surface where they can be removed by skimming. When calcium chloride is added to water containing fluorides, silicates, phosphates, sulfates, and heavy metals, it reacts with the contaminants to form highly insoluble salts, which precipitate, settle and can then be removed from the bottom of the stream.
    3.Calcium Chloride Ice Melting
    Calcium chloride has long been proven as a professional grade snow and ice melter. It consistently delivers safe surfaces for commercial and residential building owners and facilities managers without damaging granite steps, tile entrance ways, or sensitive environmentally friendly landscape features and surrounding vegetation

    Advantages of Using Calcium Chloride Flakes and Pellets for Dust Suppression
    Calcium chloride is the first choice for road dust control products. Why? The reasons are many:

    • Calcium chloride is hygroscopic, meaning it attracts moisture from the air and its surroundings. This keeps unpaved surfaces damp and the dust down.
    • Cal chloride  also resists evaporation, so a single application provides ongoing benefit.
    • Calcium chloride’s thirst for moisture helps bind aggregate particles together. Unpaved surfaces become and remain compacted and over time, the chemical penetrates the surface adding a stabilizing effect to reduce frost damage and overall wear.
    • Maintenance costs for a calcium chloride-treated road are much less than untreated roads.

    Dry CaCl2 in flake and pellet form will work well in most existing equipment that is set up to spread sand and salt products in the winter. New England Townships have used calcium chloride to manage unpaved surfaces, including dirt roads and parking areas, for years. This cost effective process reduces the amount of labor required to maintain unpaved surfaces that typically require grading and rolling several times of year when calcium is not applied. Our most popular calcium chloride dry products for dust management are our calcium chloride flakes  in super sacks and 25kg bags, and our calcium chloride pellets.
    Whether building new roads or rehabilitating existing roads, simply spreading calcium chloride on the surface, or using it in full-depth reclamation technique, calcium chloride is the dust control material of choice.
    Storage:
    Solid calcium chloride is both hygroscopic and deliquescent. This means that the product can absorb moisture from the air, even to the point of converting to liquid brine.
    For this reason, solid calcium chloride should be protected from excessive exposure to moisture to maintain product quality while in storage. Store in a dry area. Opened packages should be tightly resealed after each use.
