Research progress on the method of determining gas–water relative permeability curve in unconventional reservoirs
Published 2025-02-01“…The research results show: (1) The gas–water relative permeability curve has broad applications, and its precise measurement is essential for the efficient and economical development of gas reservoirs. (2) Current research on the unsteady-state method in unconventional reservoir applications generally focuses on improving the experimental method by combining the NMR, CT, and DPT techniques or optimizing the JBN method by considering the threshold pressure gradient, stress sensitivity, and gas slippage effect. (3) When experimenting with relative permeability curves in ultra-low permeability core samples is difficult or impossible, the indirect calculation can be used as an alternative to quickly obtaining numerous relative permeability curves. …”
