===Liquid permeability by unsteady-state method===

A technique based on pulse decay analysis<ref name=pt05r6>Amaefule, J. O., Masuo, S. T., 1986, Use of [[capillary pressure]] data for rapid evaluation of formation damage or [[stimulation]]: Society of Petroleum Engineers Paper No. 12475.</ref> has been developed recently to determine effective permeability to liquid for low quality reservoir rocks. The authors reviewed computational techniques and experimental protocols for liquid permeability determination. A technique that allows the simultaneous determination of liquid permeability and compressibility was also developed. A detailed discussion of this technique is beyond the scope of this article, therefore, interested readers are referred to<ref name=pt05r6 />.
