Sodium chloride has multiple functions in drilling and completion fluids. It is used to increase the fluid density, reduces the freezing point of water base drilling fluids, inhibits hydrate formation, provides shale control. … It is used as a base brine for completion and workover fluids.

Applications Sodium chloride has multiple functions in drilling and completion fluids. It is used to increase the fluid density, reduces the freezing point of water base drilling fluids, inhibits hydrate formation, provides shale control. … It is used as a base brine for completion and workover fluids.

Advantages A water-based solution of inorganic salts used as a well-control fluid during the completion and workover phases of well operations. Brines are solids free, containing no particles that might plug or damage a producing formation. In addition, the salts in brine can inhibit undesirable formation reactions such as clay swelling. Brines are typically formulated and prepared for specific conditions, with a range of salts available to achieve densities ranging from 8.4 to over 20 lbm/gal (ppg) [1.0 to 2.4 g/cmo]. Common salts used in the preparation of simple brine systems include sodium chloride, calcium chloride and potassium chloride.
