Weighting Material Calcium Chloride
Purity: 94% min
Form: granular form
Product Description:
Calcium Chloride (CaCl2) powder is a single salt used to form clear‐brine workover
and completion fluids with densities ranging from 8.4 to 11.8 lb/gal (1007 to 1414 kg/m3). These fluids are used where formation pressures require densities from 8.4 to 11.8 lb/gal (1007 to 1414 kg/m3) or where the inhibitive properties of a calcium fluid are required to prevent the hydration and migration of swelling clays. CaCl2can be mixed with CaBr2 to obtain densities up to 15.1 lb/gal (1809kg/m3). When used with ZnBr2, densities to 19.2 lb/gal (2301 kg/m3) can be achieved.

Applicant
Calcium Chloride brine is used in clear‐brine completion or workover fluids that require densities between 8.4 and 11.8 lb/gal (1007 to 1414 kg/m3). Calcium Chloride powder can be used to achieve rapid density increases with minimal
volume addition. It also provides inhibition preventing the hydration and migration of swelling clays and can be used in packer fluids.
Calcium Chloride fluids can be formulated with various crystallization points and
are available for special applications and winter use. Use gentle agitation for thorough dispersion.
Note: Use Mixing Tables to obtain the desired density and crystallization temperature
Advantages:
Mixes readily with all other calcium‐ and zinc‐base brines.
Package and Storage
Calcium Chloride powder is packaged in 80‐lb (36‐kg) bags.
Store in a dry, well‐ventilated area. Keep container closed. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink‐wrapping and/or stacking
