..., and the macropores contain the organic matter. The occurrence of the double peak in the NMR data indicates the shift from strong to weak diffusional coupling and thus the isolation of the micritic pore space from the macropore space for both molecular diffusion and fluid flow. In this dual-porosity Type-IIS self...

... with the second, post-treatment, analysis revealed the amount of the removed organic matter. An estimation of bitumen solubility, based on previous analysis on pure bitumen samples, allowed the assessment of total bitumen amount. An analogous procedure was set up for cuttings samples and its feasibility proved...

... ABSTRACT Workflows for log analysis in conventional reservoir rocks are difficult to apply in organic-rich mudrocks due to the presence of abundant kerogen (solid, insoluble organic matter). There are two key reasons for this difficulty. First, kerogen is part of the solid matrix but responds...
