Proppant placement in rough fractures is controlled by coupled effects of operating parameters, particle settling, and fracture-surface heterogeneity, yet quantitative criteria for evaluating final placement remain limited. This study reanalyzes previously obtained large-scale visualization data from a 20.3 m × 4.5 m ×...
Two-meter-scale true-triaxial hydraulic-fracturing models involve a large monitoring volume, strongly nonuniform microseismic event densities, and substantial vibration and background noise, making conventional fixed-scale clustering or direct geometric fitting prone to cluster fragmentation, event-band mixing, and low...
To address the relatively high near-wellbore fracture-initiation resistance and the tendency of hydraulic fractures to propagate along a dominant path under conventional perforation-based hydraulic fracturing, three large-scale hydraulic-fracturing experiments were conducted using a 10,000-ton ultra-large true-triaxial...
