Sotka Dam Seepage; Evaluation and Possible Remediation
Sulaimani Journal for Engineering Sciences, 2016 One of the most important analysis that should be done before the construction of an embankment dam is the seepage analysis. Inaccurate analysis of the seepage through the foundation or the dam body will lead to inaccurate design of the seepage control ...

Deep Underground Science and Engineering, EarlyView.This paper presents temporal and adaptive‐frequency network with MixStyle (TAMNet), a deep time‐series modeling framework for accurate and robust multi‐well oil productivity forecasting. TAMNet integrates transformer and long short‐term memory architectures to capture both short‐ and long‐term temporal dependencies, enhanced by a temporal gate unit ...

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 ...

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