Spatial Variations in Methane Content and Their Main Controlling Factors of the Deep‐Buried Coalbed in the Nalinhe–Hengshan Area, Ordos Basin

Energy Science &Engineering, EarlyView.
Ash yield is the primary geological factor controlling the spatial variations in the total gas content of the deep‐buried coalbed methane in the Nalinhe‐Hengshan area, Ordos Basin. However, porosity dominates the differential enrichment of the free gas content of the deep‐buried coalbed methane in the Nalinhe‐Hengshan area, Ordos Basin.

Stability Evaluation and Parametric Optimization of Coal‐Concrete Composite Bearing Systems Under Mine‐Water‐Induced Deterioration: Experiments and FEINN Analysis

Energy Science &Engineering, EarlyView.
Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

Designing Orthogonal‐Arc Trajectories for Horizontal Wells to Reduce Drilling Cost in Development of Shale Oil/Gas Reservoirs

Energy Science &Engineering, EarlyView.
Designing 3‐dimensional (3D) horizontal well trajectories is critical for enhancing drilling efficiency in shale reservoirs. This paper proposes an innovative Orthogonal‐Arc Trajectory (OAT) for 3D horizontal wells, which employs a single constant curvature in the curved section.
