n: R-SO3-M (R is alkyl, M is cation),a kind of anionic surface active agent, mainly used as foaming agent of foam drilling fluid, for example alkane sulfonate.

calcium carbonate.

adj: containing or composed largely of calcium carbonate, or calcite (CaCO3)

n: calcium carbonate, CaCO3

n: CaCO3, a natural calcium carbonate. Its relative density is from 2.6 to 2.8. A kind of heavy loader.

calcium carbonate, CaCO3. May be rock (limestone) or a scale formed from super saturated solution at the site of a chemical or physical upset.

n: [CH3(CH2)11SO3]2Ca, a kind of anionic surface active agent. Usually used for emulsion of water-in-oil drilling fluid.

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

n: 1. a salt of carbonic acid. 2. a compound containing the carbonate radical (CO3) 3. a carbonate rock.

n: The different carbonate of alkaline earth element.

any of the many rocks composed of calcium carbonate (limestone) or magnesium carbonate (dolomite) or other acid soluble rocks with a common CO3-2 ionic charge. The pores may be poorly connected and matrix permeability (non fractures) are often much lower

n: a type of sedimentary rock similar to limestone but containing more than 50 percent magnesium carbonate;sometimes a reservoir rock for petroleum.

n: A kind of natural compound whose can be expressed by CaCO3.MgCO3


calcium/magnesium carbonate rock. Dolomite is formed by chemical modification of a limestone.

iron carbonate scale.
