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.

the theoretical maximum flow that a well could deliver with a zero backpressure at the middle of the perforations.

n: the theory that minerals such as oil and gas are fully owned in place before they are extracted and reduced to possession. Despite this theory, title to oil and gas may be lost by legitimate drainage and by the rule of capture. Also called ownership in place. See rule of capture.
