n: The abnormal pressure per meter in depth, usually express as MPa/m. It is the reference
of density of the mud and the procedure of the casing design.

n: A formation that has porosity, fracture and cavity. It can cause the mud loss during drilling.

n: one of usually two, three, or more mud tanks that holds drilling mud that is being circulated into a borehole during drilling. They are called active tanks because they hold mud that is currently being circulated.

n: 1. in general, a substance added in small amounts to a larger amount of another substance to change some characteristic of the latter. In the oil industry, additives are used in lubricating oil, fuel, drilling mud, and cement. 2. in cementing, a substance added to cement to change its characteristics to satisfy specific conditions in die well. A cement additive may work as an accelerator, retarder, dispersant, or other reactant.

n: The agent put into the drilling fluid in order to change some performances of the drilling fluid or slurry.

a compound incorporated into a gas, liquid, or solid system to alter the properties for a particular purpose.

n: The substance that can increase mud making rate of bentonite.

n: The certain temperature in which mud and slurry lay in order to check out the variable relations between time and performance of mud and slurry.

n: a motor-driven paddle or blade used to mix the liquids and solids in drilling mud.

n: A mechanically driven impeller used to stir the drilling fluid to assist in the suspension of solids, blending of additives, and maintenance of uniform consistency.
