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

calcium chloride salt.

n: a moisture-absorbing chemical compound, or desiccant, CaCI2, used to accelerate setting times in cement and as a drying agent. It is also added to fresh water to increase the waters weight and to give it desirable properties during well completion or workover.

n: CaCl2, a kind of absorption chemical compound.Usually used for calcium mud and heavy weight additive of completion fluid.

CaCl2, a water soluble brine weighting agent.

n: Refers to the calcium mud that uses calcium chloride as calcium salt. Its performance is high rejection capability.

n: The water base drilling fluid handled by lime, gypse and calcium chloride.

n: See accelerator.

an additive such as calcium chloride, and salt in high concentrations that speeds the set of cement.

n pi: a slurry of portland cement and water and sometimes one or more additives that affect either the density of the mixture or its setting time. The portland cement used may be high early strength, common (standard),or slow setting. Additives include accelerators (such as calcium chloride),retarders (such as gypsum),weighting materials (such as barium sulphate),lightweight additives (such as bentonite),or a variety of lost circulation materials (such as mica flakes).

n: The bonding material for cementing.

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: setting cement which is added calcium chloride arised in early of 2oth years.

n: 1. a drilling mud in which the water has an appreciable amount of salt (usually sodium or calcium chloride) dissolved in it. Also called saltwater mud or saline drilling fluid. 2. a mud with a resistivity less than or equal to the formation water resistivity.
