Experimental variogram modelling is an essential process in geostatistics. The use of artificial intelligence (AI) a new and advanced way automating experimental modelling. One part this AI approach the population search algorithms to fine-tune hyperparameters for better prediction performing. We Bayesian optimization first time find optimal learning parameters more precise neural network regressor goal leverage capability consider previous regression results improve output using three variograms as inputs one training, calculated from ore grades four orebodies, characterised by same genetic aspect. In comparison architectures, Bayesian-optimized demonstrably achieved superior Coefficient determination validation 78.36%. This significantly outperformed non-optimized wide, bilayer, tri-layer configurations, which yielded 32.94%, 14.00%, −46.03% determination, respectively. improved reliability demonstrates its superiority over traditional, regressors, indicating that incorporating can advance modelling, thus offering accurate intelligent solution, combining geostatistics specifically machine

The reservoir quality of the Lower Goru Formation is highly variable due to its heterogeneous nature influenced by sea level fluctuations during Early Cretaceous period. This study applies an unsupervised machine learning workflow, integrating Principal Component Analysis (PCA) for dimensionality reduction, Self-Organizing Maps (SOM) clustering, and fuzzy classification geological labeling, alongside petrophysical evaluation cross-plot analysis, assess impact clay minerals on in NIM-Tay block, Indus Basin, Pakistan. Petrophysical analysis delineates a potential zone (1455–1517 m) characterized 13.9% effective porosity 27.3% water saturation. first four principal components explain approximately 90% dataset variance. Electrofacies distinguishes facies—Impermeable Reservoir, Potential Non-Reservoir, Tight Reservoir—each corresponding specific mineral assemblages. Cross-plot electrofacies reveal that facies dominated chlorite montmorillonite preserve (15%) permeability (888.87 mD), whereas kaolinite-rich mixed-layer significantly reduce quality. provides reproducible scalable framework with workflows, offering improved characterization not only Basin but also similar sandstone reservoirs globally.

This study investigates countercurrent air-water two-phase flow in vertical pipes with inner diameters of 26 mm and 44 a height 2000 mm, under controlled conditions to eliminate heat mass transfer. Cutting-edge techniques were employed measure the liquid film thickness (δ) entrainment (e) within annular pattern. The methodology involved systematic comparative analysis experimental results against established models, identifying most accurate methods for predicting behavior. Specifically, Schubring et al. correlation was found accurately predict e pipes, while Wallis more pipes. Additionally, interfacial shear stress analyzed, confirming high precision δ parameters. research enhances understanding by providing reliable estimation different pipe emphasizes significance determining stress.
