n: The process that the performance of drill fluid deteriorates due to calcium ion of cement entering into drill fluid when drilling cement plug with fluvioterrestrial drill fluid.

n: See cement contamination.

n: (SAPP) a thinner used in combination with barite, caustic soda, and fresh water to form a plug and seal off a zone of lost circulation.

n: a sequestering agent used to treat cement contamination and a deflocculant for low-temperature water muds.

n: the half-neutralized sodium salt of carbonic acid, NaHCO2, used extensively for treating cement contamination and occasionally other calcium contamination in drilling fluids.

n: A chemical with the formula NaHCO3. It is called bicarb at the drilling rig and is used to treat cement contamination in water mud. When cement hydrates, substantial amounts of lime, Ca(OH)2, are produced. As the cement sets, less free lime is available.

used for treating cement contamination and calcium contamination in muds.

n: Na2CO3, used extensively for treating various types of calcium contamination. Also called soda ash.

n: A chemical with the formula Na2CO3. It is called soda ash at the drilling rig and is used to treat most types of calcium ion contamination in freshwater and seawater muds. For cement contamination, sodium bicarbonate is used. Calcium ions from drilling gy
