Investigation of methane adsorption mechanism on Longmaxi shale by combining the micropore filling and monolayer coverage theories
S Zhou, Y Ning, H Wang, H Liu, H Xue - Advances in Geo-Energy …, 2018 - sciopen.com
Understanding the methane adsorption mechanism is critical for studying shale gas storage
and transport in shale nanopores. In this work, we conducted low-pressure nitrogen
adsorption (LPNA), scanning electron microscopy (SEM), and high-pressure methane
adsorption experiments on seven shale samples from the Longmaxi formation in Sichuan
basin. LPNA and SEM results show that pores in the shale samples are mainly
nanometersized and have a broad size distribution. We have also shown that methane …
