Cyclic irrigation of turfgrass using a shallow saline aquifer
… the long-term effects of applying shallow saline aquifer water to two turfgrass sports fields. The water (0.69-- 3.4 dSm-1) was applied using cyclic irrigation during peak demand months (May--Oct). Treatments consisted of cycling saline water through the existing irrigation systems. Saline …

Migration and trapping of CO₂ in saline aquifers
… is the large-scale injection of CO2 into deep saline aquifers. After injection, upward leakage of the CO2 is a primary concern because it will be buoyant relative to the ambient groundwater and, as a result, will rise toward the top of the aquifer and may migrate laterally away from the …

Physiological response of two turfgrass species to increasing drought and salinity stress using a line source gradient
… to investigate the feasibility of using the saline aquifer, existing beneath the Las Vegas valley, as an alternative irrigation source for turfgrass. Results indicated that the aquifer could be used as a supplemental irrigation source, without any diminished turfgrass quality, if total water …

Reduced-Order Modelling and Observations of Geological Carbon Dioxide Storage
… with much of the storage capacity found in saline aquifers. The key aim of carbon sequestration is the long-term or permanent storage of CO2 within the sub-surface, minimising the potential for CO2 leakage back to the surface. When CO2 is injected into a saline aquifer, it rises until it …

Uncertainty analysis of capacity estimates and leakage potential for geologic storage of carbon dioxide in saline aquifers
… capacity estimates and leakage potential for a saline aquifer. Six geologic parameters are treated as uncertain: porosity, irreducible water saturation, the endpoint relative permeability of CO₂, residual gas saturation, viscosity of water, and viscosity of the brine. The results of the …

Analytical modeling of CO₂ migration in saline aquifers for geological CO₂ storage
… CO₂ will be trapped in the pore space of the aquifer rock as the plume migrates and spreads; this phenomenon, known as capillary trapping, is an ideal mechanism for geological CO₂ storage because the trapped gas is immobile and distributed over a large area, greatly decreasing the risk of …

Comprehensive analysis of an ongoing CO2 storage project
… of an ongoing CO2 storage project in a deep saline aquifer located in the Citronelle field in Mobile, Alabama. A full field reservoir model was built using information from the actual field site and reservoir scale simulations are performed. Initially we evaluated different trapping …

A simulation study of injected CO₂ migration in the faulted reservoir
… Accordingly, the CO₂ sequestration into a deep saline aquifer is a subject of intensive study with current reservoir simulators incorporating dissolution, dispersion of CO₂ in water, and chemical reactions of CO₂ with existing phases and host rock. However, there is little information in the …

An Economic Study of Carbon Capture and Storage System Design and Policy
… coal-fired power plants and three potential deep-saline aquifer sequestration sites. In turn OptimaCCS generates 1) a cost-effective CCS pipeline network for transporting CO2 from all the power plants to the possible storage sites, and 2) an estimate of the costs associated with the CO2 transport …

Carbon Dioxide Flooding Induced Geochemical Changes in a Saline Carbonate Aquifer
… for geologic sequestration in either deep saline aquifers or depleted oil reservoirs. Little is known about the geochemical reactions that take place when supercritical carbon dioxide is injected into deep saline aquifers at geologic conditions similar to those found in potential …

Pore Wetting in Desalination of Brine Using Membrane Distillation Process
… freshwater production via desalination of saline waters. Seawater and saline aquifer sources represent 97.5% of all water on Earth. Hence, treating even a small portion of saline water could significantly reduce water shortage. Although reverse osmosis is one of the state-of-the-art …

Monitoring Sub-Surface Storage of Carbon Dioxide
… rate of $\sim$0.85~Mt~yr$^{-1}$ into a pristine, saline aquifer at the Sleipner carbon capture and storage project. A suite of time-lapse, three-dimensional seismic reflection surveys have been acquired over the injection site. This suite includes a pre-injection survey acquired in 1994 and seven …

Study of reactive flow, ground deformation and real-time tomography with applications on CO₂ sequestration
… owing to sequestration of CO₂ in a carbonate saline aquifer, and a validation of a new, real-time, tomography method that monitors the velocity change resulting from hydraulic fracturing. In Chapter 2, a network approach that models the formation of wormholes from reactive flow of high …

CO₂ geosequestration in the Lakota Formation, Powder River Basin, WY, USA
Deep saline aquifers have been identified as suitable repositories for geologic carbon sequestration due to their vast storage capacity, widespread distribution, and low potential for leakage. Among these potential sites, the Cretaceous deep saline aquifer Lakota Formation in the Powder River Basin …
