Steady state gas permeameter and porosimeter (Poroperm)

The versatile POROPERM determines both porosity and permeability to gas of plug-sized core samples. Specifically, porosity is determined from an isothermal nitrogen expansion and the application of Boyle’s law and Charles’ law. Gas permeability determination is achieved via the steady-state method, and subsequently the equivalent liquid permeability and slip is obtained by linear interpolation. The standard configuration consists of a control console, a quick-release Hassler core holder, a matrix cup and a data acquisition computer station enabling both manual and automatic operation. A hydrostatic high-grade stainless steel core holder can be provided for overburden pressure studies.
