Pore structure and fractal characteristics of Wufeng–Longmaxi formation shale in northern Yunnan–Guizhou, China

In this study, the microscopic pore characteristics of shale in marine strata are evaluated. Based on field emission scanning electron microscopy (FE-SEM), low-temperature N 2 adsorption (LT-N 2 GA), low-pressure CO 2 adsorption (LP-CO 2 GA) and high-pressure methane adsorption (HPMA) experiments, t...
