Abstract: There is described a method for measuring a parameter of a core sample. The method comprises injecting a fluid into a permeable core sample, allowing the injected fluid to flow out of the core sample by reducing a pressure in an exterior of the core sample relative to an interior of the core sample, measuring a flow rate of the fluid flowing out of the core sample, measuring a pressure of the fluid flowing out of the core sample, and determining, using the measured flow rate and the measured pressure, a parameter of the core sample. The parameter comprises one or more of a permeability and a pore volume of the core sample. A corresponding system is also described.
