n: The physicist A. E. Boycott found that the blood cell deposits faster when test tube deflects, especially 40°-50°, than when test tube is vertical. The same situation will be found in the drilling fluid in the horizontal well. That is why people call this

n: the density of a solid or liquid substance at a specified temperature. Sometimes referred to as true density or density in vacuo. See density.

n: a hypothetical temperature at which there is a total absence of heal Since heat is a result of energy caused by molecular motion, there is no motion of molecules with respect to each other at absolute zero.

zero point on the absolute temperature scale;equal to -273.16 degrees C, or 0 degrees K (Kelvin),or -459.69 degrees F, or 0 degrees R (Rankine).

n: the maximum volume of natural gas that can be processed through an absorber at a specified absorption oil rate, temperature, and pressure without exceeding pressure drop or any oilier operating limitation.

n: According to the characteristic that different substances absorb different light spectrum, it can be used to investigate and survey the molecule structure, kinds and attribution of the organic compounds.

A chemical that speeds up the rate of a chemical reaction. Most common are the accelerators used in cementing.

place where personnel spend their off-duty time on a rig.

n: material of high specific gravity formed during the chemical refining treatment of oils by sulphuric acid and usually separable by settling or centrifuging. Also called acid tar.

n: the process of recording the acoustic characteristics of sub- surface formations, based on the time required for a sound wave to travel a specific distance through rock. The rate of travel depends on the composition of the formation, its porosity, and its fluid content. Also called sonic logging.

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.
