Vinci Coreval system

The Coreval-30 comprises permeameter and porosimeter units. The porosimeter is based on Boyle’s law Single Cell Method for direct pore volume measurement using Nitrogen gas at 400 psi confining pressure and a maximum of 250 psi pore pressure. Plug diameter of 1'' or 1.5'' and length of 1''- 3''. The permeability test methodology is the unsteady state (transient) pressure condition for gases known also as Axial Gas Flow, Pressure-Falloff to measure the Klinkenberg slip-corrected gas permeability. The test is automated and better used in impermeable samples. Permeability range of tens of nano-Darcies up to 5,000 mD​.

Coreval30 device for determination of porosity, grain density, gas permeability, corrected liquid permeability, gas slippage factor “b”.
