n: the horizontal coordinate of a point in a plane obtained by measuring parallel to the x-axis. Compare ordinate.

(abs) adj: independent or unlimited, such as an absolute condition, or completely unadulterated, such as alcohol.

estimation/measurement of age of a formation, fossil, etc., in years before the present.

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: the force in dynes that a stationary flat plate with a surface area of 1 square centimetre exerts on a similar parallel plate 1 centimetre away and moving in its own plane with a velocity of 1 centimetre per second, the space between the plates being filled with the liquid in question. It is a measure of the resistance that the liquid offers to shear. absolute error n: the difference between the result of a measurement and the true value of the measured quantity as determined by means of a suitable standard device.

a filter rating that purports to set the maximum size of an opening in a filter or the maximum size of the particle that can pass through the filter. The definition varies with use and company.

n: the amount of moisture present in the air. It may be expressed in milligrams of water per cubic metre of air. Compare relative humidity.

n: the value obtained when the absolute dynamic viscosity is divided by the density (expressed in grams per cubic centimetre) of the liquid at the temperature concerned.

n: the maximum flow rate that a well could theoretically deliver with zero pressure at the face of the reservoir.

the maximum rate that a well can produce at the lowest possible bottom hole pressure.
