A new automated, computer-directed, core measurement system furnishes porosity, air permeability, equivalent non-reactive liquid permeability (Klinkenberg), and Forcheimer (turbulence) factor at programmable, sequential overburden pressures from 500 to 10,000 psi. The system is accurate, precise, and flexible and furnishes enhanced routine core data. Capabilities and limitations of the system are discussed. Data are presented for selected rock types and a graphical technique is proposed to relate the system measured porosity and permeability values to uniaxial strain conditions.
