... of tight-rock analysis (TRA), x-ray diffraction (XRD), and rock-eval pyrolysis. Compared with the quartz-rich OGW plugs, the EOW plugs are categorized as calcite-rich shale (calcareous shale) with high average calcite content of 60%. The EOW plugs are rich in organic matter (average total organic carbon...

... software was used to simulate opening of a fracture in the shaly and kerogen rich members of the Bakken formation. Then results were compared with a shale simple model missing organic matter properties. Results showed organic matter mechanical characteristics affects the hydraulic fracturing simulation...

... compared with brine. The positive correlations of TOC content with effective porosity and pressure-decay permeability suggest that the majority of connected pores are present within the organic matter. Organic porosity may explain the strong oil-wetness of the shale samples. The SEM/EDS analyses also show...

... experimental work to account for the presence of kerogen (organic matter) in vapor-liquid equilibrium calculation. Experiments have been performed in this work that show the combined effect of kerogen presence and confinement on oil bubble point. In the current work, kerogen is isolated from a shale sample...

... within the clay matrix aligns with regions with substantial Kr and CO 2 gas storage. In contrast, clay-rich matrix regions lacking secondary carbonate cementation exhibit minimal gas storage potential. Causes for this unexpected result include reduced gas accessibility and, possibly, low organic matter...

... of solvent-extraction on grain density, pore network attributes (surface area, pore volume, pore size distribution) and permeability of the Montney samples depends on the organic matter content, solvent type and other sample-to-sample variations. For one dataset (batch A), the change in petrophysical...

... to be active only in organic matter. To capture different transport controls in reservoirs with an overwhelming number of fine pore throats, the models include three different permeability conduit networks including organic and inorganic matrix, and natural fractures. Physical properties contributing to flow...

... study revealed that the Mancos shale is marginally mature (%Ro ~ 0.66–0.70), gas prone and has a total organic content of 1.0–1.3 wt%. It is observed that even if the porosity of the organic matter itself is very low, organics are found in or around all analyzed fractures and voids in the Mancos sample...

FESEM images from sections of samples in natural and pyrolized state show significant changes in shales with higher TOC than in leaner shales. After pyrolysis, texture and distribution of organic matter in high TOC samples resemble...

... evidence that the maximum size of pores originating in organic matter is determined by the size of the kerogen mass (in the case of organic particles) or the geometry of enclosing crystals (in the case of amorphous, pore-filling kerogen). Pairs of secondary and ion-milled backscatter SEM images address...
