System and method for measuring liquid permeability

Abstract

A method for measuring steady-state permeability of a rock sample by restoring the permeability samples to their native state of saturation. The method including determining in-situ conditions of the rock sample, including a in-situ saturation, a reservoir temperature, and a reservoir pressure. The rock sample is assessed to determine its water and hydrocarbon saturation and to identify any coring artifacts within the rock sample. The rock sample is then saturated with water and hydrocarbons so that the sample saturation is substantially equal to the in-situ saturation. Once the saturation of the rock sample is verified, reservoir temperature and reservoir pressure are applied to the rock samples and the coring artifacts are monitored. Flow testing is then performed so that a steady-state liquid permeability of the rock sample is measured.
