Abstract Lithofacies identification plays a pivotal role in understanding reservoir heterogeneity and optimizing production tight sandstone reservoirs. In this study, we propose novel supervised workflow aimed at accurately predicting lithofacies complex heterogeneous reservoirs with intercalated facies. The objectives of study are to utilize advanced clustering techniques for facies evaluate the performance various classification models prediction. Our methodology involves two-information...
Abstract Geoscientists now identify coal layers using conventional well logs. Coal layer identification is the main technical difficulty in coalbed methane exploration and development. This research uses advanced quantile–quantile plot, self-organizing maps (SOM), k-means clustering, t-distributed stochastic neighbor embedding (t-SNE) qualitative log curve assessment through three wells (X4, X5, X6) complex geological formation to distinguish from tight sand shale. Also, we reservoir rock...
The Mahu sag slope area, which holds significance as an oil and gas resource, still have some underexplored regions because of structural mismatches, presenting a potential challenge to be properly addressed. To resolve, this study conducts comprehensive investigation concerning characteristics, fault combinations, favorable reservoir distribution, control factors, oil-water distribution characteristics within the Triassic Baikouquan Formation, evaluating impact depositional environments...
Rock-physics templates establish a link between seismic properties (e.g., velocity, density, impedance, and attenuation) reservoir such as porosity, fluid saturation, permeability, clay content. We focus on based attenuation (seismic [Formula: see text] or quality factor), which are highly affected by those properties, we consider carbonate reservoirs that constitute 60% of the world oil reserves potential for additional gas reserves. The described with mesoscopic-loss models, White model...
The Hangjinqi area was explored for natural gas around 40 years ago, but the efficient consideration in this started a decade ago pure exploration. Many wells have been drilled, yet remains an exploration area, and potential zones are still unclear. Lower Shihezi Formation is proven reservoir northern Ordos Basin. This study focuses on second third members of to understand controlling factors faults sedimentary facies distribution, aimed identify favorable accumulation within area. research...
For the successful discovery and development of tight sand gas reserves, it is necessary to locate with certain features. These features must largely include a significant accumulation hydrocarbons, rock physics models, mechanical properties. However, effective representation such reservoir properties using applicable parameters challenging due complicated heterogeneous structural characteristics hydrocarbon sand. Rock modeling sandstone reservoirs from Lower Goru Basin fields represents...
Precision porosity and facies determinations are critical in reducing drilling uncertainty increasing hydrocarbon recoveries from heterogeneous sources. The distribution of the Taiyuan-Shanxi Formations (T9c-T9d), Shihezi-1 Formation (T9d-T9e) within Hangjinqi area uncertain no studies have covered spatial on a regional scale. nature coal, mudstone, sandstone makes it challenging to comprehend lithofacies. Also, seismic resolution is not able resolve reservoir heterogeneity. Therefore, we...
Reservoir characterization is a vital task within the oil and gas industry, with identification of lithofacies in subsurface formations being fundamental aspect this process. However, complex geological environments high dimensions, such as Lower Indus Basin Pakistan, poses notable challenge, especially when dealing limited data. To address issue, we propose four common data-driven machine learning approaches: multi-resolution graph-based clustering (MRGC), artificial neural networks (ANN),...

Subsequently, a sent 163 physicians nationwide who had undergone advanced Department...
Abstract Fractures play a vital role in reservoir transformation, but the distribution of faults and fractures is difficult to obtain by observing cores, which ultimately limits effective development gas dolomite reservoirs. We propose an integrated method that incorporates thin-section observations, three-dimensional (3D) seismic data, image logs interpret Cambrian Longwangmiao Carbonate Formation predict potential areas Moxi-Gaoshiti area Sichuan Basin, South China. Firstly, were well...

Nine automatically graded through specific A.I-based algorithm clinically assessed by panel experts dermatologists. Selfie...
Shear velocity is an important parameter in pre-stack seismic reservoir description. However, the real study, high cost of array acoustic logging leads to lacking a shear curve. Thus, it crucial use conventional well-logging data predict velocity. The prediction methods mainly include empirical formulas and theoretical rock physics models. When using formula method, calibration should be performed fit local data, its accuracy low. modeling, many parameters about pure mineral must optimized...
Shale samples from the Ordovician Wulalike Formation at western margin of Ordos Basin are studied to define types, microstructures and connectivity pores as well relationships between pore structures gas content by using experimental techniques such high-resolution field emission scanning electron microscopy (FESEM), mercury injection capillary pressure (MICP), low-temperature nitrogen adsorption (LTNA), CO2 adsorption, focused ion beam (FIB-SEM). The results show that shale has 10 different...
Hydrogen peroxide (H2O2) levels play a vital role in redox regulation and maintaining the physiological balance of living cells, especially cell mechanotransduction. Despite achievements on strain-induced cellular H2O2 monitoring, applied voltage for electrooxidation possibly gave rise to an abnormal expression inadequate accuracy, which was still inescapable concern. Hence, we decorated interlaced CuO@TiO2 nanowires (NWs) semiconductor meshwork onto polydimethylsiloxane film-supported gold...
