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

open access: yesEnergy 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 ...

Underground Storage of Natural Gas

open access: yes, 1989
The total global primary energy consumption for the year 1986 amounted to 322 000 PJ = 10 989 million tonnes HCE (hard coal equivalent). The percentage share of the various energy sources is shown in Fig. 1. Assuming a global population of 5 billion people this represents an average annual per capita consumption of about 2 t HCE.

Prediction method and application of the effective period of oil and gas formation by transport of oil source fault

open access: yesFrontiers in Earth Science
The effective period of hydrocarbon formation has a significant impact on oil and gas enrichment. Based on an analysis of the mechanism of oil and gas formation by oil source fault transport, the transport period is determined by both the activity period

A Resilience‐Based Reward‐Penalty Scheme for Hardening Electricity Distribution Assets Against High‐Impact, Low‐Probability Disasters

open access: yesEnergy Science &Engineering, EarlyView.
This paper introduces a novel resilience‐based reward‐penalty scheme (RPS) for electricity grids facing high‐impact, low‐probability (HILP) disasters. By modeling the costs of proactive asset immunization against reactive RPS penalties, our analysis conclusively demonstrates that long‐term investment in grid resilience is the more economically rational

Recovery Factor of Pure Helium Injection in Depleted Gas Reservoirs and Its Influencing Factors

open access: yesEnergy Science &Engineering, EarlyView.
This study employs compositional numerical simulation to systematically investigate the effects of injection rate, production rate, storage duration, and injection‐production scheme on pure helium recovery in depleted gas reservoirs. Low injection rates reduce viscous fingering while high production rates maximize near‐wellbore helium extraction ...
