Influence of the Geometric Characteristics of Fractures Induced by the Sandstones With Different Strength on the Hydro‐Mechanical Behaviors Within a Single Rock Fracture

open access: yesEnergy Science &Engineering, EarlyView.
Higher compressive strength in sandstone fractures leads to smoother surfaces, smaller apertures, and more contact, which reduce transmissivity but increase the critical pressure gradient for nonlinear flow initiation. ABSTRACT The correlation between rock compressive strength and fracture roughness represents a significant area of research within the ...

Coupled Assessment of Injection Pressure–Driven Risk, Trapping Evolution, and Cost Uncertainty in Geological CO2 Storage

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Scaling geological CO2 storage requires simultaneously controlling plume migration, pressure buildup, geomechanical integrity, and monitoring cost under deep subsurface uncertainty. Yet early‐stage assessments often treat these elements in isolation, obscuring the decision‐critical couplings between pressure‐defined regulatory exposure and ...

Late Pleistocene Volcanic Rocks From Tengchong Volcanic Field at SE Tibetan Plateau: Constraints on Petrogenesis and Mantle and Crustal Processes

open access: yesGeological Journal, EarlyView.
Early zircon saturation and crystallisation occur in mafic (52–54 wt.% SiO2) lavas at Tengchong volcanic field. These early formed zircons with high δ18O (6.6‰–7.9‰) indicates mantle enrichment by subducted supracrustal materials. ABSTRACT Late Pleistocene (< 0.2 Ma) mafic and evolved volcanic rocks occur in northern Tengchong Volcanic Field, SE ...
