Calcium Chloride (CaCL2) 3
Calcium Chloride (CaCL2) 3 :
(n.) Drilling Fluids. A highly soluble calcium salt of formula CaCl2 used to make drilling and workover fluids or brines with a density range from 8.33 to 11.6 lbm/gal [1.39 g/cm3] at saturation. CaCl2 can be blended with other brines, including sodium chloride [NaCl], calcium bromide [CaBr2] and zinc bromide [ZnBr2]. Emulsification of CaCl2 brine as the internal phase of oil-base orsynthetic-base mud is an important use because the brine provides osmotic wellbore stability while drilling water-sensitiveshale zones.
