Impact of methane adsorption on tight rock permeability measurements using pulse-decay

open access: yesPetroleum, 2019
The permeability of the rock is usually measured by the injection of gas using Darcy's flow model (pulse-decay). For oil formations, helium and nitrogen are the most common gases used to measure the permeability of the rock.
