Abstract
Because of unknown faults and fractures in the overlying rock, CO2 stored deep underground may move upward, and the intrusion may impact shallow groundwater quality. After leakage of CO2 has ceased, the affected aquifer may show remediation capacity under natural conditions and injections and extractions. In this study, the reactive transport modeling software TOUGHREACT was used to simulate the remediation capacity of a study aquifer. The simulation results show that the intrusion of leaked CO2 would decrease the pH of the target aquifer and trigger the dissolution of calcite minerals. After CO2 leakage has ceased, the pH would increase as would the concentration of Ca because of the dissolution of calcite along the flow path. Scenario simulation results of amelioration of groundwater quality by water injection and extraction show that single injection is the best option and a combination approach of injection and extraction could control the range of the affected area. The pH value should not be regarded as the single indicator for remediation capacity assessment. Parameter sensitive analysis results show that the rates of injection and extraction affect the repair results significantly.

Enhanced oil recovery through carbon dioxide injection (CO2-EOR) data has made it possible to estimate the CO2 geological storage in the oilfields of the Songliao Basin, northeastern China. The storage capacity of CO2 in oilfields was determined and the results show that the theoretical storage capacity of CO2 in the oilfields of the Songliao Basin is 2.36 × 109 t, and the effective storage capacity is 0.59 × 109 t with an effective coefficient of 0.25. Among the tectonic units, the central down...

The dissolution of CO 2 in water leads to a pH decrease and a carbonate content increase in affected groundwater, which in turn can drive the mobilization of metals from sediments. The mechanisms of metal release postulated in various field and laboratory studies often differ. Drawing primarily on previously published results, we examine contrasting metal mobilization behaviors at two field tests and in one laboratory study, to investigate whether the same mechanisms could explain metal releases...

This study presents a combined use of site characterization, laboratory experiments, single-well push–pull tests (PPTs), and reactive transport modeling to assess potential impacts of CO2 leakage on groundwater quality and leakage-detection ability of a groundwater monitoring network (GMN) in a potable aquifer at a CO2 enhanced oil recovery (CO2 EOR) site. Site characterization indicates that failures of plugged and abandoned wells are possible CO2 leakage pathways. Groundwater chemistry in the ...

Abstract Geological storage of CO 2 is one option for mitigating atmospheric emissions of carbon dioxide. However, the injected CO 2 has the possibility of leakage. The leaked CO 2 may move upward into shallow formations and thereby affects shallow groundwater. To investigate this effect, 27 tonnes of gaseous CO 2 was injected into an aquifer about 180 m below a surface. Periodic groundwater samples were studied to identify shift of hydro-chemical parameters, including pH, TDS, ORP, Ca, Mg, Na, ...

Abstract Here we provide a comprehensive study of the fundamental physics both numerically and analytically, of the combined influence of heterogeneity, viscous forces, gravity, and capillarity on multiphase flow of CO 2 and brine. Specifically, steady-state 3D coreflood displacements in heterogeneous cores over a range of relevant conditions are simulated to study the impact of sub-core heterogeneity on CO 2 /brine displacements over a wide range of flowrates. Various degrees of heterogeneity a...

This paper presents a basin‐scale model study of the behaviors of CO 2 plume and the potential environmental impacts for large‐scale CO 2 storage in the saline aquifers of Songliao Basin, China. The model covers the whole basin, and vertically consists of most of the Cretaceous strata. In a hypothetical scenario, a total of 1.43 GT CO 2 is injected into the Yaojia Formation (K 2 y) through 20 wells distributing at the center of the basin in 50 years (0.5–2 million tons per injection well per yea...

Solution of Laplace’s equation can be done by iteration methods likes Jacobi, Gauss–Seidel, and successive over-relaxation (SOR). There is no new knowledge about the relaxation coefficient (ω) in SOR method. In this paper, we used SOR for solving Laplace’s differential equation with emphasis to obtaining the optimum (minimum) number of iterations with variations of the relaxation coefficient (ω). For this purpose, a code in FORTRAN language has been written to show the solution of a set of equat...

Geological storage of CO 2 in deep saline aquifers has become one of the most important methods of reducing the emission of anthropogenic greenhouse gas into the atmosphere. The assessment of potential CO 2 storage capacity is an important part of geological storage design. In this study, the potential CO 2 storage capacity in the deep saline aquifers of the Songliao Basin – a large sedimentary basin in northeastern China – was assessed on a basin scale. The study results showed that: (1) deep s...

Capturing carbon dioxide (CO2) emissions from industrial sources and injecting the emissions deep underground in geologic formations is one method being considered to control CO2 concentrations in the atmosphere. Sequestering CO2 underground has its own set of environmental risks, including the potential migration of CO2 out of the storage reservoir and resulting acidification and release of trace constituents in shallow groundwater. A field study involving the controlled release of groundwater ...

Abstract A field experiment involving the release of carbon dioxide (CO 2 ) into a shallow aquifer was conducted near Bozeman, Montana, during the summer of 2008, to investigate the potential groundwater quality impacts in the case of leakage of CO 2 from deep geological storage. As an essential part of the Montana State University Zero Emission Research and Technology (MSU-ZERT) field program, food-grade CO 2 was injected over a 30 day period into a horizontal perforated pipe a few feet below t...

Abstract Mineral dissolution and secondary mineral precipitation can cause porosity and permeability changes of CO 2 storage reservoirs and caprocks after injection of CO 2 . In this paper, a 3-step approach (core-scale experiment →core-scale modeling →reservoir-scale modeling) is developed to simulate reservoir-scale porosity and permeability evolution of CO 2 storage formation and caprock at a model CO 2 storage site. The model site is based on characteristics of a real site in Mississippi, US...

This study focused on typical injection layers of deep saline aquifers in the Shiqianfeng Formation used in the Carbon Capture and Sequestration Demonstration Projects in the Ordos Basin, Northwest China. The study employed experiments and numerical simulations to investigate the mechanism of CO2 mineral sequestration in these deep saline aquifers. The experimental results showed that the dissolved minerals are plagioclase, hematite, illite–smectite mixed layer clay and illite, whereas the preci...
