... Abstract Most shale oil resources in China are lacustrine deposit. The reservoirs are usually characterized by complex lithology and high heterogeneity with various mineral compositions (quartz, carbonates, feldspars, pyrites and volcanic ash), total organic carbon and pore structure. How...

... petrophysical characteristics, complex pore structure, and so on, especially for lacustrine shale oil formation. This paper describes an approach and workflow to characterize the Chang7-3 member shale oil reservoir in the Ordos basin, China by integrating the high tech digital rock physics core analysis data...

.... In particular, micro focused X-ray CT (MXCT) scanners with high energy x-ray beam attaining high resolution have been drastically developed in a decade. Meanwhile, the study with respect to multi-phase flow in porous media desires to get more quantitative parameters of the particle shape and pore structure...

... pore structures. NMR measurements, although counted among the most reliable methods to measure formation porosity, has been conventionally considered as insensitive to the existence of natural fractures. Thus, the impact of natural micro-fractures on NMR measurement has rarely been investigated. We...

... overbalance with water-based mud (WBM) presents several key challenges: severe near-wellbore formation damage, lack of porosity-permeability relationships because of the complex pore structures, large-scale permeability effects from pronounced heterogeneities, and big discrepancies among the permeability...

... Abstract Carbonate rocks frequently exhibit velocity-porosity relationships less predictable than those found in siliciclastics because of complex and heterogeneous pore structures. Traditional pore-type classifications describe these pore structures but are inadequate for correlations...

... pressure curves can be constructed, which could be used to evaluate reservoir pore structure and calculate reservoir originality water saturation in the intervals with NMR log data. At last, the constructed NMR capillary pressure curve by this new method is used in well site to detect the change...

... Abstract Reservoir rocks often present complex pore-structures involving multiple porosity systems with various interconnectivity patterns. These pore-systems, from microporosity to vugs/fissures, drastically affect petrophysical properties. This is particularly true for electrical properties...

... Abstract The prediction of hydrocarbon recovery is related to both the detailed pore scale structure of core material and fluid interfacial properties. An increased understanding of displacement efficiencies and overall recoveries requires an ability to characterize the pore structure...
