One of the most important reservoir parameters is the permeability, which defines the ability of a liquid to flow through a porous medium. In our laboratories, we have various setups available to determine the permeability at different pT conditions. The standard sample sizes are (D/L) 25 mm/50 mm and 30 mm/40 mm. Permeability is generally measured in a steady state (Darcy or Darcy-Klinkenberg), but it is also possible to determine low permeabilities using the transient pressure pulse method. …
