94-95% oil drilling grade anhydrous calcium chloride
Calcium chloride is used in a variety of drilling products such as drilling muds, completion fluids, packer fluids, workover fluids, and concrete accelerators. The reasons for calcium chloride’s popularity are many and include:
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.
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 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.
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.
Once the casing is cemented into place, a smaller diameter pipe, the tubing, is inserted into the casing. 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.
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.
