Quantitative Insights into Atomic Scale Oil–Clay Adhesion Governing Shale Oil Retention and Mobility
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Atomic force microscopy reveals a clear adhesion hierarchy between shale oil and clay minerals, governed by nanoscale surface chemistry. Strong interactions on chlorite and illite arise from abundant polar sites and cation bridging, whereas weaker coupling on montmorillonite limits interfacial binding.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Despite the crucial need for fully quantitative risk assessment of large‐scale structures, their performance is typically assessed through deterministic or semi‐quantitative approaches. The main preventing factor is the computational burden of probabilistic seismic analyses.

Energy Science &Engineering, EarlyView.Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

Triple Porosity Model and Its Application for Coal Seam Gas Injection Displacement of CH4
Energy Science &Engineering, EarlyView.(1)Compared with injecting CO2, injecting N2 has a shorter penetration time, but the CH4 flow rate takes longer to stabilize, meaning the displacement process lasts longer. (2)The flow rate of CH4 rapidly decreases and gradually approaches 0; the flow rates of N2 and CO2 are 0 before breakthrough, then increase rapidly and eventually stabilize.

Energy Science &Engineering, EarlyView.Formed ~1.4 Ga, the carbonate reservoir of the Jixian System is a key geothermal reservoir in northern China. Differential basin–mountain evolution since the Cenozoic led to distinct reservoir‐forming histories; consequently, this same reservoir shows marked productivity contrasts between intramontane basins and the large rift Bohai Bay Basin ...
