NMR porosity is used as an independent validation for total porosity, and NMR clay-bound water is used to calibrate cation exchange capacity (CEC) for clays. Water-filled porosity from dielectric logs is used to calibrate water saturation...

... production often show a quite different water cut than the total water saturation from traditional static formation evaluation. To quantify fluid porosities of immobile and producible hydrocarbon and water, we have developed a novel interpretation workflow integrating NMR T 1 - T 2 log and multi-physics...

... mineral compositions and total organic carbon content for hydrocarbon saturation. NMR factor analysis determined the T2 cutoff for free fluid porosity. Combining free fluid porosity with hydrocarbon volume data from total organic carbon and resistivity measurements accurately characterize the fluid type...

... for porosity, permeability, mineralogy, and mechanical properties using NMR, XRD, and triaxial compression testing. A 3D reservoir-scale numerical model quantifies stress evolution and CO 2 migration over a 36-year simulation period. Results demonstrate significant pore structure alteration after CO 2 soak...

... Abstract Understanding effective permeability in carbonate shales tends to be difficult to predict as the shale presents heterogeneous mineralogy, poorly nano- and micro-pores system, carbonate secondary porosity as dissolution may be also present. Understand fluid types in this reservoir...

... Abstract Storage capacity and injectivity in CCS projects depend on physical properties like porosity and permeability within injection zones, the overall volume of the zone, and whether the system allows fluid flow. In stress-sensitive reservoir rocks, increasing reservoir pressure...

... reservoirs, as kerogen-rich source rocks do not always correlate with favorable reservoir properties. The Jurassic lacustrine shale oil reservoirs are characterized by complex mineralogy, low-to-medium kerogen abundance, low porosity, and diverse fracture networks. Consequently, advanced reservoir...

... Abstract Phase decomposition isolates seismic facies that are obscured by interference from adjacent reflections. For thin layers with a zero-phase wavelet, the -90° phase highlights low-impedance facies, which can be correlated to high porosity. Below seismic resolution, sparse layer...

... Abstract Shale reservoirs with high total organic carbon have complex porosity systems hosted within both inorganic matrix and organic matters. It has been presumed that the porosity distribution among inorganic and organic pores has a direct impact on well productivity. The objective...

...-exposure analyses included measurements of Young's modulus and Poisson's ratio using the NER Autolab 1500 system. Mineralogical alterations were characterized using X-ray diffraction (XRD), while microstructural changes were examined using scanning electron microscopy (SEM). Porosity and pore structure...

... Abstract Developing a consistent characterization model for unconventional reservoirs is challenging due to the rarity of core-measured true effective porosity, saturation, and relative and absolute permeability data. This challenge intensifies for basin-wide application, as advanced data...

With the matrix density derived from spectroscopy measurements, the porosity calculated has a difference compared with the NMR porosity, which confirms the existence of the bitumen in the reservoir. Bitumen and oil volume were evaluated based on the method...

Such elevated formation resistivity can result in a lower Archie water saturation, particularly in less favorable reservoir facies. On the contrary, observed formation resistivity is typically very low in the clean, high-porosity, high...
