Manufacturer: Vinci Technologies
Model Number: Corevel 30
The Coreval 30 instrument is dedicated to measure the porosity and permeability to helium/nitrogen of plug sized core samples at a fixed confining pressure of 400 psi maximum . The instrument is provided with a data acquisition and calculation computer station. Permeability measurements are made using the unsteady state pressure drop method. This data is used to determine the equivalent liquid permeability, slip and turbulence factors. Equivalent air permeability at a user specified pressure is also computed. Porosity and pore volume measurements are made using the Boyle’s and Charles’ law technique.
