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.

n: a measure of the ability of a single fluid (such as water, gas, or oil) to flow through a rock formation when the formation is totally filled (saturated) with that fluid. The permeability measure of a rock filled with a single fluid is different from the permeability measure of the same rock filled with two or more fluids. Compare effective permeability, relative permeability.

permeability to a single phase fluid in a cleaned core.

n: the percentage of the total bulk volume of a rock sample that is composed of pore spaces or voids. See porosity.

the percentage of the total bulk volume that is pore spaces, voids or fractures.

n: total pressure measured from an absolute vacuum. It equals the sum of the gauge pressure and the atmospheric pressure. Expressed in pounds per square inch.

the reading of gauge pressure plus the atmospheric pressure.

temperature measurement starting at absolute zero (total absence of heat).

n: the property by which a fluid in motion offers resistance to shear and flow. Usually expressed as newton seconds/metre.

the measure of a fluid’s ability to resist flow without regards to its density. It is defined as a fluid’s kinematic viscosity multiplied by its density.

the volume a solid occupies when added to a fluid divided by its weight. m3/kg or gal/lb.

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).

v: I. to take in and make part of an existing whole. 2. to recover liquid hydrocarbons from natural or refinery gas in a gas- absorption plant. The wet gas enters the absorber at the bottom and rises to die top, encountering a stream of absorption oil (a light oil) travelling downward over bubblecap trays, valve trays, or sieve trays. The light oil removes, or absorbs, the heavier liquid hydrocarbons from the wet gas. See bubble-cap tray, sieve tray, valve tray.

to fill part or all of the pore spaces.
