n: a substance capable of reacting with an acid to form a salt. A typical base is sodium hydroxide (caustic),with the chemical formula NaOH. For example, sodium hydroxide combines with hydrochloric acid to form sodium chloride (a salt) and water. This reaction is written chemically as NaOH + HCl -+ NaCI + H2O.

n: water that has a large quantity of salt, especially sodium chloride, dissolved in it;salt water.

n: Dissolving a great quantity of salt, especailly sodium chloride. Usually used to make up salt water drilling fluid.

a mixture of water and a soluble salt. Most common brines are sodium chloride NaCl, potassium chloride KCl and calcium chloride CaCl2. Brine densities may range from 8.33 to > 19 lb/gal (1 to >2.28 g/cc). The USGS definition of a brine is a salinity of mo

n: a drilling fluid made up mainly of chemical salts, such as sodium chloride, calcium chloride, or potassium chloride. Clear brine contains little or no clay or other solid material and is virtually transparent. It is often used when drilling into a producing formation because clear brine minimises formation damage. See completion fluid formation damage.

a brine without suspended solids.

n: rock salt (NaCI).

n: a kind of nature saline formation whose primarcy component is solium chloride

sodium chloride, NaCl.

sodium chloride salt. Halite.

n: CMC that made from alkaline cellulose and chloroacetic acid, the product of that is purified by alcohol removing sodium chloride.

n: The rock stratum that mainly contain sodium chloride crystal .




a diverter that is used in acids. Best for high permeability and fractures.

n: a compound that is formed (along with water) by the reaction of an acid with abase. A common salt (table salt) is sodium chloride, Naa, derived by combining hydrochloric acid, Ha, with sodium hydroxide, NaOH. The result is sodium chloride and water, H2O. This process is written chemically as Ha + NaOH ~ NaCI + H2O. Another salt is calcium sulfate, CaS�4, obtained when sulfuric acid, H2SO4 is combined with calcium hydroxide, Ca (OH)2

specifically sodium chloride, but also may be a generic term for most water soluble salts.

n: a cementing slurry whose liquid phase contains sodium chloride.
