Comprehensive characterization of petrophysical properties in shale by solvent extraction experiments and 2D NMR
Fuel(2023)
Abstract
•A new joint experiment is designed for petrophysical evaluation in shale.•Dissolved methanol can be used to identify hydrogen components in shale.•1D/2D translational diffusion model is introduced for theoretical analysis of shale NMR mechanism.•A comprehensive interpretation scheme of shale is established based on T1/T2-T2 map.•Wettability and mobility characteristics of shale are provided through interpretation scheme.
