n: liquid chemical derived from benzene or from benzene and ammonia. It is used as a solvent and in the organic synthesis of other substances.

n: C6H7N, colourless and oil like liquid, tang and toxic. Usually used in measuring content of aromatic hydrocarbon in drilling fluid operation.

n: the lowest temperature at which the chemical aniline and a solvent (such as the oil in oil-base muds) will mix completely. In general, the oil of oil-base muds should have an aniline point of at least 150F (66"C) to obtain maximum service life from the rubber components in the mud system.

n: The lowest temperature in which the same volume of oil and aniline dissolve in each other.

the aromatics content of a mixture.

n: C6H6 colourless, volatile, flammable toxic liquid aromatic hydrocarbon used as a solvent and as a motor fuel.

an aromatic (cyclic or ring structure) compound, present in very minor quantities in many crude oils.

n: an off-line method of compressor cleaning in which the compressor is washed with water and detergent or solvents. Ineffective for removing baked-on contaminants.

n: a test involving the observation of a formation sample immersed in solvent and under ultraviolet light. If any hydrocarbons, which fluoresce under ultraviolet light, are in the sample, they will dissolve and appear as streamers or streaks of colour different from the solvent.

n: a device that uses a solvent to reflux, or flow back over, a sample to clean it. Such a device extracts oil or salt-laden water efficiently without harming the core samples.

n: the dispersion of solids that have stuck together in drilling fluid, usually by means of chemical thinners. See flocculation.

n: (1) The process of thinning the drilling fluid by bonding with (neutralizing or covering) the positive electrical charges of drilling fluid additives to prevent one particle of drilling fluid from being attracted to another particle. (2) Breakup of flocs

dispersing a clump or a gathering or “flocculated” of particles. Usually accomplished by dispersants or solvent thinners.

n: a combination of a demulsifier and solvent that is used during testing for the suspended S& W content of oil and during other operations.

n: 1. the spontaneous movement and scattering of particles of liquids, gases, or solids. 2. the migration of dissolved substances from an area of high concentration to an area of low concentration.

n: A process in which the molecular ,ion or material in the solvent disperse until the uniform solution forms. Namely a process in which the molecular, ion or material move from the high concentration area to the low concentration area until the whole solu

the random scattering of particles due to kinetic energy of the particles. Affected by viscosity, density and temperature.

diaminopropanoltetraacetic acid, a calcium scale remover and solvent.
