Sodium Chloride (NaCl) Brine Systems are single-salt solutions of sodium chloride and water.

Sodium Chloride Brine Systems have densities ranging from 8.4 to 10.0 lb/gal (1,007 to 1,198 kg/m3). The desired density is obtained by blending saturated 10.0 lb/gal (1,198 kg/m3) sodium chloride brine with water or by mixing dry NaCl with the appropriate amount of freshwater. Sodium Chloride Brine Systems are also used to form non-damaging Flo-Pro* drill-in fluids.

Typical Physical PropertiesPhysical appearance ............................................................................................................................................................................................... Clear liquid

pH (Neat) ........................................................................................................................................................................................................................... 6.5 - 7.0

Clarity ......................................................................................................................................................................................................... Crystal clear, <3 NTU

ApplicationsSodium Chloride Brine Systems are used extensively in low-density, clear- fluid workover and completion operations such as shallow low-pressure wells which do not require the special inhibitive properties of calcium or potassium systems. These fluids are also used to adjust the density of other non-saturated brines such as seawater, potassium chloride and ammonium chloride. Note: Use the Blending Tables to obtain the desired density.

Toxicity and HandlingBioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions as described on the Material Safety Data Sheet (MSDS). Also observe the health hazard information and emergency and first aid procedures described on the MSDS.

Packaging and Storage Sodium Chloride Brine Systems are packaged in bulk liquid quantities. Store in appropriate corrosion- resistant brine containers and keep closed and firmly sealed.
