This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: EGS using CO2 as a working fluid will likely involve hydro-shearing low-permeability hot rock reservoirs with a water solution. After that process, the fractures will be flushed with CO2 that is maintained under supercritical conditions (> 70 bars). Much of the injected water in the main fracture will be flushed out with the initial CO2 injection; however side fractures, micro fractures, and the lower portion of the fracture will contain connate water that will interact with the rock and the injected CO2. Dissolution/precipitation reactions in the resulting scCO2/brine/rock systems have the potential to significantly alter reservoir permeability, so it is important to understand where these precipitates form and how are they related to the evolving 'free' connate water in the system. To examine dissolution / precipitation behavior in such systems over time, we have conducted non-stirred batch experiments in the laboratory with pure minerals, sandstone, and basalt coupons with brine solution spiked with MnCl2 and scCO2. The coupons are exposed to liquid water saturated with scCO2 and extend above the water surface allowing the upper portion of the coupons to be exposed to scCO2 saturated with water. The coupons were subsequently analyzed using SEM to determine the location of reactions in both in and out of the liquid water. Results of these will be summarized with regard to significance for EGS with CO2 as a working fluid.

This book was released on 2017-10-09 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: A surge of interest in the geomechanical and petrophysical properties of mudrocks (shales) has taken place in recent years following the development of a shale gas industry in the United States and elsewhere, and with the prospect of similar developments in the UK. Also, these rocks are of particular importance in excavation and construction geotechnics and other rock engineering applications, such as underground natural gas storage, carbon dioxide disposal and radioactive waste storage. They may greatly influence the stability of natural and engineered slopes. Mudrocks, which make up almost three-quarters of all the sedimentary rocks on Earth, therefore impact on many areas of applied geoscience. This volume focuses on the mechanical behaviour and various physical properties of mudrocks. The 15 chapters are grouped into three themes: (i) physical properties such as porosity, permeability, fluid flow through cracks, strength and geotechnical behaviour; (ii) mineralogy and microstructure, which control geomechanical behaviour; and (iii) fracture, both in laboratory studies and in the field.

Download or read book Geologic Carbon Sequestration written by V. Vishal and published by Springer. This book was released on 2016-05-11 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: This exclusive compilation written by eminent experts from more than ten countries, outlines the processes and methods for geologic sequestration in different sinks. It discusses and highlights the details of individual storage types, including recent advances in the science and technology of carbon storage. The topic is of immense interest to geoscientists, reservoir engineers, environmentalists and researchers from the scientific and industrial communities working on the methodologies for carbon dioxide storage. Increasing concentrations of anthropogenic carbon dioxide in the atmosphere are often held responsible for the rising temperature of the globe. Geologic sequestration prevents atmospheric release of the waste greenhouse gases by storing them underground for geologically significant periods of time. The book addresses the need for an understanding of carbon reservoir characteristics and behavior. Other book volumes on carbon capture, utilization and storage (CCUS) attempt to cover the entire process of CCUS, but the topic of geologic sequestration is not discussed in detail. This book focuses on the recent trends and up-to-date information on different storage rock types, ranging from deep saline aquifers to coal to basaltic formations.

This book was released on 2020-03-04 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Open system behavior is predicated on a fundamental relationship between the timescale over which mass is transported and the timescale over which it is chemically transformed. This relationship describes the basis for the multidisciplinary field of reactive transport (RT). In the 20 years since publication of Review in Mineralogy and Geochemistry volume 34: Reactive Transport in Porous Media, RT principles have expanded beyond early applications largely based in contaminant hydrology to become broadly utilized throughout the Earth Sciences. RT is now employed to address a wide variety of natural and engineered systems across diverse spatial and temporal scales, in tandem with advances in computational capability, quantitative imaging and reactive interface characterization techniques. The present volume reviews the diversity of reactive transport applications developed over the past 20 years, ranging from the understanding of basic processes at the nano- to micrometer scale to the prediction of Earth global cycling processes at the watershed scale. Key areas of RT development are highlighted to continue advancing our capabilities to predict mass and energy transfer in natural and engineered systems.

This book was released on 2013 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the supercritical CO2-water-mineral systems relevant to subsurface CO2 sequestration, interfacial processes at the supercritical fluid-mineral interface will strongly affect core- and reservoir-scale hydrologic properties. Experimental and theoretical studies have shown that water films will form on mineral surfaces in supercritical CO2, but will be thinner than those that form in vadose zone environments at any given matric potential. The theoretical model presented here allows assessment of water saturation as a function of matric potential, a critical step for evaluating relative permeabilities the CO2 sequestration environment. The experimental water adsorption studies, using Quartz Crystal Microbalance and Fourier Transform Infrared Spectroscopy methods, confirm the major conclusions of the adsorption/condensation model. Additional data provided by the FTIR study is that CO2 intercalation into clays, if it occurs, does not involve carbonate or bicarbonate formation, or significant restriction of CO2 mobility. We have shown that the water film that forms in supercritical CO2 is reactive with common rock-forming minerals, including albite, orthoclase, labradorite, and muscovite. The experimental data indicate that reactivity is a function of water film thickness; at an activity of water of 0.9, the greatest extent of reaction in scCO2 occurred in areas (step edges, surface pits) where capillary condensation thickened the water films. This suggests that dissolution/precipitation reactions may occur preferentially in small pores and pore throats, where it may have a disproportionately large effect on rock hydrologic properties. Finally, a theoretical model is presented here that describes the formation and movement of CO2 ganglia in porous media, allowing assessment of the effect of pore size and structural heterogeneity on capillary trapping efficiency. The model results also suggest possible engineering approaches for optimizing trapping capacity and for monitoring ganglion formation in the subsurface.

Download or read book Negative Emissions Technologies and Reliable Sequestration written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-04-08 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.

Download or read book Supercritical Carbon Dioxide brine rock Reactions in the Madison Limestone of Southwest Wyoming written by Curtis G. Chopping and published by . This book was released on 2012 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal-fired power plants emit significant amounts of carbon dioxide (CO2), in addition variable amounts of sulfur dioxide (SO2). One proposed strategy to reduce these gases to the atmosphere is to capture, inject and store them into geologic formations, a process often referred to as Carbon Capture and Storage (CCS), or carbon sequestration. In the case of mixed gas, co-sequestration. To help predict long term storage behavior, we can look at naturally occurring carbon dioxide reservoirs, otherwise known as natural analouges. The Madison Limestone on the Moxa Arch, southwest Wyoming, houses a natural carbon dioxide reservoir that can serve as a natural analogue for geologic carbon-sulfur co-sequestration. This thesis is an experimental geochemical study that evaluated multiphase (SO2 -CO2 -H2O)-brine-rock reactions and processes through a series of hydrothermal experiments representing the naturally occurring sulfur-rich Madison Limestone carbon dioxide reservoir. The first experimental series investigated multiphase-(CO2 -H2O)-brine-rock reactions representing the natural Madison Limestone system. Synthetic Madison Limestone (dolomite-calcite-anhydrite-pyrite) and Na-Cl-SO42−brine ( I = 0.5 molal) reacted at 110°C and 25 MPa for approximately 81 days (1940 hours). Supercritical carbon dioxide was injected and the experiment continued for approximately 46 days (1100 hours). A parallel experiment was performed without supercritical carbon dioxide to provide a basis of understanding the interaction of supercritical carbon dioxide with the brine-rock system. The second experimental series tested the hypothesis the Madison Limestone is a natural analogue to co-sequestration. In all aspects, it was conducted in the same manner as the first experimental series, but did not contain any initial anhydrite in the mineral assemblage (dolomite-calcite-pyrite). This series assumed that all aqueous sulfate was from fully reacted sulfur dioxide to examine supercritical CO2-sulfur reactivity. The third and final experimental series simulated a co-sequestration scenario by repeating series one and two, incorporating 500 ppm sulfur dioxide co-injected with carbon dioxide. Injection of supercritical carbon dioxide into the experiments decreased pH, increased Eh, and drove reaction pathways along the pyrite-anhydrite saturation boundary of the relevant Eh-pH diagram. The dolomite-calcite-anhydrite mineral assemblage and reaction textures that were produced are consistent with those observed in the natural carbon dioxide reservoir. Bulk mineralogy following injection of supercritical carbon dioxide, ± supercritical sulfur dioxide does not change. Minerals are instead dissolved, mobilized and re-precipitated. Injection of carbon dioxide, ± supercritical sulfur dioxide, precipitates anhydrite, providing a mineral trap for sulfur in a carbon-sulfur co-sequestration scenario. Anhydrite precipitation decreases sulfate activity, ultimately leading to mineralization of carbon dioxide. These experimental results support the hypothesis that the Madison Limestone on the Moxa Arch is a natural analogue for geologic carbon-sulfur co-sequestration. Equilibrium geochemical calculations accurately predicted concentrations for conservative ions Na+ and Cl− . Aqueous Ca2+ and Mg2+ predictions differed from experimentally measured values, in part, due to carbonate mineral solid solution and, in part, because the experiments do not achieve equilibrium. A minimum of 10,000 hours of laboratory reaction time with supercritical carbon dioxide, ± supercritical sulfur dioxide, is needed to achieve equilibrium. Equilibrium laboratory experiments can predict the long-term fate of reactive carbon in a natural carbon dioxide reservoir as well as a sequestration scenario, even if equilibrium is not achieved on the laboratory scale. A supplemental electronic file containing all thesis data (ThesisData_CChopping2012.xlsx) was also submitted.
