Abstract:
The dataset includes the measured gas permeability data of sample L1P and L1V under different pressure conditions (confining pressure and pore pressure), in the comment you will find the fitted results of response surface model (RSM). All data was measured by PoroPDP-200 full-automatic instrument (Core Lab, USA) based on pressure pulse decay technique, with nitrogen as the probing gas.
Sampling site is Heye Village, Shuanghe Town, Changning County, Sichuan Province (Latitude: 28.392287 * Longitude: 104.887276).
