Research on the Mechanism of Sand Bridge Stuck Drill in Deep Coal and Rock Gas Horizontal Wells

Energy Science &Engineering, EarlyView.
Accounting for wellbore collapse debris and the bulldozer effect, this study develops models for permeable and impermeable sand bridge sticking in deep CBM horizontal wells, deriving resistance and volume formulations. Validated in Changqing, results show impermeable bridges dominate; controls (fluid optimization, staged drilling, circulation, speed ...

Influence of Technological and Environmental Factors on the Major Ion Composition in Cooling Water Discharges of a Nuclear Power Plant

Energy Science &Engineering, EarlyView.
Statistical modelling and grey water footprint analysis revealed how technological and environmental factors shape the major ion composition of cooling water discharges from a nuclear power plant. Findings highlight that while ion concentrations increase post‐discharge, they remain within regulatory limits, ensuring minimal ecological impact.
