Comprehensive characterization and evaluation of deep shales from Wufeng-Longmaxi Formation by LF-NMR technology

Unconventional Resources, 2022
Marine deep shale gas represents the main target of future shale gas development in China. In order to identify the key parametric characteristics of deep shales, a comprehensive test method and application study was carried out based on LF-NMR technology. The results show that the NMR T2 spectrum of shales varied considerably in different states.
