n: The cement made by bauxite and limestone. This cement is heatproof, non-corrodible and firm in the early stage. Applied in geothermal well and thermal recovery well.

n: CaBr2`6H2O, white powder. A kind of liquid heavy weight additive, usually for heavy brinish completion fluid.

CaBr2, water soluble brine weighting agent.

n: a chemical combination of calcium, carbon, and oxygen, CaCO3 It is the main constituent of lime-stone. It forms a tenacious scale in water-andling facilities and is a cause of water hardness.

n: CaCO3, white powder or crystal. Used for fluid loss agent of non-soil phase completion fluid and heavy weight additive of drill fluid.

CaCO3, limestone, a common formation or when in particles, a weighting or fluid loss agent.

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: dissolved calcium ions in sufficient concentration to impart undesirable properties, such as flocculation, reduction in yield of bentonite, and increased fluid loss, in a drilling fluid. See also anhydrite, calcium carbonate, calcium sulphate, gypsum, lime.

n: The process that calcium ion enters into the drilling fluid when drilling in the calcareous formation or cement plug.

n: the active ingredient of slaked (hydrated) lime, and the main constituent in cement (when wet). Referred to as lime" in field terminology. Its symbol is Ca(OH)2

n: Ca(OH)2, white powder. The pH value of its saturated solution is 12.4. Usually used for depressant of inorganic salt, calcium mud and clearing excessive carbanion in drill fluid.

Ca(OH)2, slaked lime.

n: a chemical combination of calcium, magnesium, carbon, and oxygen, CaMgCO3. It is the main constituent of dolomite. Compare calcium carbonate.

n: CaO, the main component of lime. White cubic crystal or powder. Mainly used for manufacturing calcic drill fluid.

CaO, quick lime.

Soda ash, bicarbonate of soda, caustic soda and some phosphates. Act to reduce the effects of calcium in a fluid.
