This paper presents a generalized mathematical model that comprehensively characterizes the flow behavior of matrix nanopores and natural/hydraulic fractures in tight oil reservoirs during spontaneous imbibition. The incorporates various influencing factors such as fracture distribution, displacement pressure gradient, gravity, buoyancy. complex pore structure reservoirs, including natural micr...

Kerogen lens shape and size distribution control how organic-rich shales may behave as either source or seal rocks. Prior to thermal conversion, kerogen is a brittle, load-bearing constituent of the shale matrix. During maturation, lenses become more ductile, hydrocarbon expulsion lead creation microfractures, process controlled not only by temperature pressure but also their total content in r...

The pore structure and its complexity play a critical role in fluid migration recovery efficiency. Multiple types, broad size distribution (PSD), extremely irregular morphology hinder the comprehensive investigation of systems their low-permeability conglomerates. In this study, multi-scale system fractal characteristics Permian Lower Wuerhe Formation Triassic Baikouquan conglomerates from Jung...

The meteoric water has obviously changed the physical properties of dolostone reservoirs in vertical vadose zone and horizontal phreatic zone, but its influence on shallow burial beneath surface is still unclear. This study aims to reveal effect through X-ray diffraction, cathodoluminescence, C, O, Sr isotope using sample from Majiagou Formation Daniudi gas field, Ordos Basin. diagenesis parage...

Biomass with a large amount of moisture is well-suited to be processed by supercritical water gasification, SCWG. The precipitation inorganics, together char formation and re-polymerization, can cause reactor plugging stop the process operations. When occurs, sudden injections relatively mass quantities take place, influencing flow dynamics significantly in process. Reactor phenomenon very well...

Articular cartilage injuries are found in up to 60% of patients who undergo an arthroscopic knee procedure, and those that totally affect articular (grade IV) have limited regenerative capacity extended time for recovery. 3-D scaffolds represent a novel solution address this type injury. Our purpose was analyze the MRI findings functional status underwent repair chondral defects either by micro...

The Shatak Formation, comprising a part of the Mashak Suite (RF2), is located on western slope Southern Urals. It consists various rock types, including sedimentary rocks, such as conglomerates, polymictic sandstones, aleurolites, and carbonaceous clayey shales, well igneous picrites, basalts, dacites, rhyodacites, rhyolites, volcanogenic–sedimentary tuffs tuff breccias. In this article, oxyflu...

Shale matrix permeability is an important indicator for evaluating gas transport and production. However, the effects of pore connectivity water saturation on in deep shales have not been adequately studied. In this study, Yichang area Middle Yangtze was characterized using three methods. These included determination apparent different directions via pulse-decay, also obtained Gas Research Inst...
