Klinkenberg-corrected gas permeability correlation for Shuaiba carbonate formation

摘要

Standard industry practice to correct absolute gas permeability for what is known as the Klinkenberg effect is to perform single point gas permeability measurement and use assumptions or existing correlations. Available correlations for Klinkenberg-correction of gas permeability are based on measurements of sandstone samples. However, correlations developed for specific fields/formations may not be applicable for other reservoirs of different lithology due to the difference in the pore geometry.
