This study employs a stacked ensemble machine learning approach to predict carbonate rocks' porosity and absolute permeability with various pore-throat distributions heterogeneity. Our dataset consists of 2D slices from 3D micro-CT images four core samples. The stacking integrates predictions several learning-based models into single meta-learner model accelerate the prediction improve model's generalizability. We used randomized search algorithm attain optimal hyperparameters for each by...
Characterizing heterogeneity in reservoir rocks at the pore scale is crucial to understand flow patterns better, and estimate petrophysical properties such as porosity permeability. This study introduces multifractals descriptors for rock samples’ scale. We analyzed twenty samples from sandstone carbonate reservoirs using their 3D X-ray micro-computed tomography images. In addition, we simulated permeability examined correlation with multifractal parameters. The results show that...
Permeability upscaling in carbonate rocks is challenging due to the heterogeneity at multiple scales. Although there are several computational methods for permeability upscaling, applicability, time, and associated accuracy of these may vary significantly. This article modified an established Karim Krabbenhoft renormalization method (KRM) proposed a regression-based rocks, results compared with classical KRM. To this end, small-scale samples (size = 5003 6003 voxels, from 405 7944 μm3) whole...
Sulfur-bearing compounds are very detrimental to the environment and industrial process equipment. They often obtained or formed as a by-product of separation thermal processing fuels containing sulfur, such coal, crude oil natural gas. The two sulfur compounds, which need special attention, are: hydrogen sulfide (H2S) dioxide (SO2). H2S is highly corrosive gas with foul smell. SO2 toxic responsible for acid rain formation equipment corrosion. Various methods reducing pollutants described in...
This paper deals with the job shop problem of simultaneous scheduling production operations and preventive maintenance tasks. To solve this problem, we develop an elitist multi-objective genetic algorithm that provides a set Pareto optimal solutions minimising makespan total cost. A deep study was made to choose best encoding, operators, different probabilities. Some lower bounds adopted criteria are developed. The computational experiments carried out on published instances validate...
One of the fundamental physical phenomena related to CO2 injection in subsurface brine-saturated formations is dissolution-diffusion-convection process CO2. The injected supercritical being less dense than brine settles beneath formation seal. overlying CO2-saturated slightly heavier itself thus a density- driven convective flow occurs which will enhance dissolution rate CO2, reduce time for solutal trapping and increase storage security. In this work experiments simulations at laboratory...

Abstract Automated image processing algorithms can improve the quality and speed of classifying morphology heterogeneous carbonate rock. Several commercial products have worked to produce petrophysical properties from 2D images with less extent 3D images, relying on flow simulation. Images are mainly micro-computed tomography (μCT), optical thin-section, or magnetic resonance (MRI). However, most successful work is homogeneous clastic rocks. In this work, we demonstrated a Machine Learning...
<p><a></a>Each grid block in a 3D geological model requires rock type that represents all physical and chemical properties of block. The classify types are lithology, permeability, capillary pressure. Scientists engineers determined these using conventional laboratory measurements, which embedded destructive methods to the sample or altered some its (i.e., wettability, porosity) because measurements process includes crushing, fluid flow, saturation. Lately, Digital Rock...
