Modeling the injection of CO 2 and its sequestration will require simulations of a multi-well injection system in a large reservoir field. However, modeling at the injection well scale is a necessary prerequisite to reservoir scale modeling. We report on the development and application of two models: 1) a semi-analytical model (PNLCARB), and 2) a numerical model (STOMP-CO 2). PNLCARB can simula...

The aim of this research was to evaluate groundwater quality for irrigation in Kalihati Upazila, Bangladesh, a region that is significantly reliant on crop development, especially during dry periods. By combining hydrochemical analysis and Geographic Information System (GIS), the examined physicochemical attributes their spatial distribution. Fifteen samples from various locations were analyzed...

In any geological subsurface fluid injection, a viable top seal is required to contain the vertical movement of injected plume. However, integrity assessment challenging because uncertainties possessed by various parameters. A probabilistic solution might be more appropriate when significant are present. this study, we evaluate Drake shale caprock structural reliability using stochastic method....

Storage of anthropogenic CO2 in geological formations relies on a caprock as the primary seal preventing buoyant super-critical CO2 escaping. Although natural CO2 reservoirs demonstrate that CO2 may be stored safely for millions of years, uncertainty remains in predicting how caprocks will react with CO2-bearing brines. This uncertainty poses a significant challenge to the risk assessment of ge...
