Total pressure measured from an absolute vacuum

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 a single 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. see also permeability

The maximum flow rate a well could theoretically deliver with zero pressure at the middle of the perforations

Contrary to the term, the science of geochronology to measure the age of rocks, minerals and fossils, in years before the present, is an inaccurate science. The measurement of the decay of radioactive isotopes, especially uranium, strontium, rubidium, argon and carbon, has allowed geologists to more precisely determine the age of rock formations. Tree rings and seasonal sedimentary deposits called verves can be counted to determine absolute age
