... Abstract Characterization of 3D channelized gas reservoirs with an aquifer is challenging due lots of variables, considering of vertical flow, properties of channel such as connectivity and pattern, and high uncertainty by an aquifer. In case of conventional EnKF (ensemble Kalman filter...

..., dissolution and mineral trapping. After the injection of CO2 in a brine aquifer, the lower density of CO2 causes buoyancy-driven flow to the top of the storage formation. When the flowing CO2 encounters a high capillary entry pressure region in a low permeability layer, the upward movement of CO2...

... ABSTRACT For a drastic reduction of GHG emission from the ship service, the idea to liquidize and store CO2 in tanks on board was investigated premising the GHG storage in the aquifers under ocean floor. As a result, ethane is the most appropriate fuel for boiler/turbine system because its...

... incapable of cleaning up a contaminated aquifer completely, there is no doubt that this method alone can remove a large portion of the contaminants from the aquifer and prevent the contamination from further spreading (Bedient et al., 1999). Capture zones delineate the area around a pumping well from which...

... In this study, we analyze the physical mechanism of water well resonance induced by pre-earthquake signals. A weak pressure wave passing through the confined aquifer is considered as the incoming pre-earthquake signal. Since the porous skeleton is hard, this pressure wave is simply the limiting...

... sites, or agricultural fields. Accurate and timely information on the spatial distribution of the contaminant is essential in the formulation of corrective action plan and environmental management strategies for aquifers. Whether or not the appropriate management of aquifer is accomplished is highly...

... ABSTRACT As most natural land developed for municipal in Taiwan the new industrial parks are forced to move to the tidal land. This idealism induces the polluted situation of aquifer in the coastal area and becoming serious. The purpose of the research is based on the groundwater hydrology...

... concentrations by graphically. Multi-flow computer programming was used to determine the distribution of contaminant concentrations with respect to time and length. The distributions of contaminant concentrations from the contaminant source were determined with respect to time, length, thickness of aquifer...
