n: See mist.

a suspension of fine liquid droplets or solid particles in a gas.

n: usually refers to drill exploration well in the radioactivity, geochemistry and gravity abnormal area.

n: the change in the chemistry of a mud from one type to another. Also called conversion.

n: the character or state of the drilling mud filter cake. According to API RP I3B, such notations as hard," "soft," "tough," "rubbery," and "firm" may be used to convey some idea of cake consistency.

n pi: (slang) certifications of materials on physical and chemistry properties.

certificates, usually on physical or chemical properties (e.g., MSDS Sheets).

n: the pressure at a given temperature for a hydrocarbon system of fixed composition at which the vapourliquid equilibrium values of the various components in the system become or tend to become unified. The convergence pressure is used to adjust vapour-liquid equilibrium values to the particular system under consideration. conversion n: the change in the chemistry of a mud from one type to another. Reasons for making a conversion may be (1) to maintain a stable well bore, (2) to provide a mud that will tolerate higher weight, or density, (3) to drill soluble formations, or (4) to protect producing zones. Also called a breakover.

n: Usually there are two methods that reclaiming diamond from old diamond bit: chemistry and electrolysis. The reclaiming prescription of electrolysis is higher than chemistry.

n: The phenomenon that dilatability clay mineral (for example, montmorillonite) transform into non-dilatability clay mineral (for example, goeschwitzite) under the condition of temperature, pressure and chemistry.

n: a kind of instrument which measres the deviation angle with pendulum and records the measured result using the action of electrochemistry

n: 1.The predominant flow geometry reflected in a pressure-transient response that is most easily recognized in the log-log presentation of the pressure-change derivative. The most easily recognized flow regime is radial flow, which produces a constant or fl

flow condition (e.g., mist, slug, churn, etc.) of a multiphase process stream.
