Multi-Lateral Well Productivity Evaluation Based on Three-Dimensional Heterogeneous Model in Nankai Trough, Japan

open access: yesEnergies, 2023
Widely employed in hydrate exploitation, the single well method is utilized to broaden the scope of hydrate decomposition. Optimizing the well structure and production strategy is necessary to enhance gas recovery efficiency. Complex wells represented by

Purification Efficiency for Treated Waste Water in Case of Joint Infiltration with Water Originating from Precipitation

open access: yesApplied Sciences, 2020
The decentralized treatment of wastewater and its on-site infiltration is common practice, especially in rural areas. However, uncertainties exist on the degradation potential of treated wastewater constituents mixed with additional infiltration of large

Asymmetric impact of groundwater use on groundwater droughts [PDF]

open access: yesHydrology and Earth System Sciences, 2020
Abstract. Groundwater use affects groundwater storage continuously, as the removal of water changes both short-term and long-term variation in groundwater level. This has implications for groundwater droughts, i.e. a below-normal groundwater level. The impact of groundwater use on groundwater droughts remains unknown. Hence, the aim of this study is to

Optimal location of cutoff walls for seawater intrusion

open access: yesApplied Water Science, 2021
In this paper, the simulation–optimization method is used to study the optimal location of cutoff walls for seawater intrusion. The optimization model is based on minimizing the chlorine concentration of two water sources after 50 years.
