One of the most important reservoir parameters is permeability, which defines the ability of a liquid to flow through a porous medium. Various set-ups are available in our laboratories to determine the permeability under different pT conditions. The standard sample sizes (D/L) are 25 mm/50 mm and 30 mm/40 mm. The permeability is always measured in a stationary manner (Darcy or Darcy-Klinkenberg), but it is also possible to determine low permeabilities using the transient pressure pulse method. …
