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...
The detailed reservoir characterization was examined for the Central Indus Basin (CIB), Pakistan, across Qadirpur Field Eocene rock units. Various petrophysical parameters were analyzed with integration of various cross-plots, complex water saturation, shale volume, effective porosity, total hydrocarbon neutron porosity and sonic concepts, gas effects, lithology. In total, 8–14% high 45–62% saturation are superbly found in reservoirs Eocene. Sui Upper Limestone is one poorest among all these...
Nowadays, there are significant issues in the classification of lithofacies and identification rock types particular. Zamzama gas field demonstrates complex nature due to heterogeneous reservoir formation, while it is quite challenging identify lithofacies. Using our machine learning approach cluster analysis, we can not only resolve these difficulties, but also minimize their time-consuming aspects provide an accurate result even when user inexperienced. To constrain models, type a critical...
Understanding geological variance in a proved reservoir requires accurate as well exact characterization of lithological facies. In the Kadanwari gas field, machine learning (ML) classification algorithms have been used to forecast facies on such an accessible dataset. The goal is increase reliability categorization using rigorous application learning. current study identify lithofacies, we self-organizing map (SOM) and crossplot techniques. reservoir, recognition lithofacies main piece...
Porosity assessment is a vital component for reservoir evaluation in the oil and gas sector, with technological advancement, reliance on conventional methods has decreased. In this regard, research aims to reduce well logging, purposing successive machine learning (ML) techniques precise porosity measurement. So, examines prediction of curves Sui main upper limestone reservoir, utilizing ML approaches such as an artificial neural networks (ANN) fuzzy logic (FL). Thus, input dataset includes...
This paper evaluated the oil and gas potential of Cretaceous Yageliemu clastic reservoir within Yakela condensed field lying in Kuqa Depression, Tarim Basin, China. The petrophysical properties interest zones area were characterized using geophysical logs from five wells. results reveal that gas-bearing are by high resistivity, good permeability (K) effective porosity (Φeff), low water saturation (Sw), shale concentration (Vsh), reflecting clean sand. distribution model showed these shales...
This study involved an interpretation of wire-line logs in assessing the hydrocarbon capacity sandstone reservoir within gas fields Kadanwari, Sindh, Pakistan. Wire-line from four wells (KD-01, KD-03, KD-10 and KD-11) were used our research provided for thirteen zones. Reservoir analyses done effective porosity (ϕeff), shale content (Vsh), net pay thickness variations, water saturation, (Sw Shc). Hydrocarbon-bearing zones consist high values resistivity, permeability, porosity, low...
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),...
Estimating above-ground biomass (AGB) is important for ecological assessment, carbon stock evaluation, and forest management.
