Book excerpt: Long term containment of stored CO2 in deep geological reservoirs will depend on the performance of the caprock to prevent the buoyant CO2 from escaping to shallow drinking water aquifers or the ground surface. Here we report new laboratory experiments on CO2-brine-caprock interactions and a review of the relevant literature. The Eau Claire Formation is the caprock overlying the Mount Simon sandstone formation, one of the target geological CO2 storage reservoirs in the Midwest USA region. Batch experiments of Eau Claire shale dissolution in brine were conducted at 200 C and 300 bars to test the extent of fluid-rock reactions. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis indicate minor dissolution of K-feldspar and anhydrite, and precipitation of pore-filling and pore-bridging illite and/or smectite, and siderite in the vicinity of pyrite. We also reviewed relevant reactivity experiments, modeling work, and field observations in the literature in an attempt to help define the framework for future studies on the geochemical systems of the caprock overlain on geological CO2 storage formations. Reactivity of the caprock is generally shown to be low and limited to the vicinity of the CO2-caprock interface, and is related to the original caprock mineralogical and petrophysical properties. Stable isotope studies indicate that CO2 exists in both free phase and dissolved phase within the caprock. Carbonate and feldspar dissolution is reported in most studies, along with clay and secondary carbonate precipitation. Currently, research is mainly focused on the micro-fracture scale geochemistry of the shaly caprock. More attention is required on the potential pore scale reactions that may become significant given the long time scale associated with geological carbon storage.
Book Synopsis Geologic Carbon Sequestration by : V. Vishal
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.

Available in PDF, EPUB and Kindle. Book excerpt: This paper presents interim results of a feasibility study on carbon dioxide (CO2) sequestration in deep saline formations. The focus of the investigation is to examine factors that may affect chemical sequestration of CO2 in deep saline formations. Findings of the first phase of this investigation were presented in a topical report (Sass et al., 1999a). Preliminary results of the second phase, now underway, have been reported elsewhere (Sass et al., 1999b; 2001). Evaluations of the suitability of Mt. Simon formation for sequestering CO2 and economic issues are reported by Gupta et al., 1999; 2001; Smith et al., 2001. This study is sponsored by the U.S. Department of Energy's (DOE) National Energy Technology Laboratory (NETL) under a Novel Concepts project grant. The overall objectives of Phase II experiments were to determine: (1) the potential for long-term sequestration of CO2 in deep, regional host rock formations; and (2) the effectiveness of overlying caprock as a barrier against upward migration of the injected CO2. To meet these goals, experiments were conducted using rock samples from different potential host reservoirs and overlying rocks. In addition, pure mineral samples were used in some experimental runs to investigate specific mineralogical reactions. Due to space limitations, the scope of this paper will be limited to two types of equilibration experiments using pure minerals. Implications for more complex natural systems will be discussed in the report for Phase II being finalized at this time.

Download or read book Geological Sequestration of Carbon Dioxide written by Luigi Marini and published by Elsevier. This book was released on 2006-10-12 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contents of this monograph are two-scope. First, it intends to provide a synthetic but complete account of the thermodynamic and kinetic foundations on which the reaction path modeling of geological CO2 sequestration is based. In particular, a great effort is devoted to review the thermodynamic properties of CO2 and of the CO2-H2O system and the interactions in the aqueous solution, the thermodynamic stability of solid product phases (by means of several stability plots and activity plots), the volumes of carbonation reactions, and especially the kinetics of dissolution/precipitation reactions of silicates, oxides, hydroxides, and carbonates. Second, it intends to show the reader how reaction path modeling of geological CO2 sequestration is carried out. To this purpose the well-known high-quality EQ3/6 software package is used. Setting up of computer simulations and obtained results are described in detail and used EQ3/6 input files are given to guide the reader step-by-step from the beginning to the end of these exercises. Finally, some examples of reaction-path- and reaction-transport-modeling taken from the available literature are presented. The results of these simulations are of fundamental importance to evaluate the amounts of potentially sequestered CO2, and their evolution with time, as well as the time changes of all the other relevant geochemical parameters (e.g., amounts of solid reactants and products, composition of the aqueous phase, pH, redox potential, effects on aquifer porosity). In other words, in this way we are able to predict what occurs when CO2 is injected into a deep aquifer.* Provides applications for investigating and predicting geological carbon dioxide sequestration* Reviews the geochemical literature in the field* Discusses the importance of geochemists in the multidisciplinary study of geological carbon dioxide sequestration
Book Synopsis Carbon Dioxide-water-rock Interaction in a Carbonate Reservoir Capped by a Clay by : Virginia M. Marcon
Download or read book Carbon Dioxide-water-rock Interaction in a Carbonate Reservoir Capped by a Clay written by Virginia M. Marcon and published by . This book was released on 2013 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep geologic formations are attractive reservoirs for geologic carbon sequestration (GCS) due to their ability to store hydrocarbons for millions of years. The technology needed for injecting CO2 into these geologic formations was established through the oil and gas industry for enhanced oil recovery (EOR) and enhanced gas recovery (EGR). However, there are some risks associated with CO2 injection such as leakage of inorganic compounds into overlying potable aquifers. Since it is difficult to avoid leakage in these systems, understanding how leaks may affect the chemistry of overlying potable aquifers is crucial. Two groups of hydrothermal experiments were performed to evaluate metal mobilization and mechanisms of release from within a storage reservoir. The first group of experiments react idealized Desert Creek limestone and/or Gothic Shale, formations in the Paradox Basin, Utah, at 160C and 25MPa in a brine (I = 3.3m). These experiments investigated the release of harmful metals from two zones within a sequestration injection reservoir: at the caprock-reservoir boundary and deeper within the reservoir. Experimental results show that CO2 injection decreases the pH by 1 to 2 units; concomitant mineral dissolution produces elevated Ba, Cu, Fe Pb and Zn concentrations in the brine. Concentrations subsequently decrease to approximately steady state values after 120-330 hours as a result of secondary mineralization of Ca-Mg-Fe carbonates, metal sulfides (i.e. Fe, As, Ag and Co sulfides), sulfates and clays. Iron, an element of secondary concern, and lead exceed the EPA regulated limits in both experiments at termination; Ba, Cu and Zn concentrations remain below the U.S. Environmental Protection Agency (EPA) maximum contaminate limits (MCL). Transition elements Cd, Cr, Cu and Zn as well as Pb, behave in a similar manner, increasing in concentration with injection but continually decreasing after about 830 hours until termination of the experiment. Nickel, not a regulated element, is also readily mobilized, and is associated with human health concerns at elevated concentrations. If brines leak from a storage reservoir and mix with a potable aquifer, the experimental results suggest that Ba, Cu and Zn will not be contaminants of concern, but Fe, Ni and Pb may require careful attention. However, experimentally observed trends of decreasing trace metal concentrations suggest that these metals could become less of a concern during the life of a carbon repository. Finally, the caprock plays an active role in trace metal evolution in the system. The caprock provides a large source of metals, but secondary mineralization and adsorption may remove metals of concern from solution. The second group of hydrothermal experiments reacted an idealized carbonate injection reservoir (Fe-rich dolomite) and caprock (illite) in a water (I =0.1m) to investigate the potential for metal mobilization and precipitation within a GCS scenario. Experiments investigated three locations within a sequestration reservoir: deep within the storage reservoir, within the caprock and at the caprock-reservoir boundary. The experiments were reacted for ~55 days: 17 days to approach steady state before CO2 is injected and 38 days to monitor changes from CO2 injection. Several major and minor ions, total dissolved CO2 and pH were monitored throughout the duration of the experiments. In all three experiments, Ca, Fe, Mg, Mn, SiO2 and SO4 increased as a result of CO2-injection, but subsequently decline through the termination of the experiments. The aqueous data supported by geochemical equilibrium modeling, FESEM images and XRD results indicate initial dissolution of illite and dolomite minerals followed by re-precipitation of Ca, Mg, Fe-carbonates, Fe, Ag-sulfides, Ba-sulfates, clays and Co, Cr, Cu, Fe, Zn-metal-oxides. Trace metals in these experiments did not exceed the U.S. EPA's primary or secondary MCL, but geochemical patterns denote valuable information for metal release, co-precipitation and adsorption of metals in a sequestration scenario. Experiments replicating an idealized carbonate injection reservoir show that metals are more readily mobilized than in experiments containing a caprock. Once the caprock is included in the system, water chemistry, FESEM and modeling results suggest increased adsorption and co-precipitation of the potentially harmful metals, which removes mobilized metals from solution. Barium, Sr and Fe are potential elements of concern in a sequestration scenario due to mobility of the metals.

Download or read book Development of Unconventional Reservoirs written by Reza Rezaee and published by MDPI. This book was released on 2020-04-16 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for energy is increasing and but the production from conventional reservoirs is declining quickly. This requires an economically and technically feasible source of energy for the coming years. Among some alternative future energy solutions, the most reasonable source is from unconventional reservoirs. As the name “unconventional” implies, different and challenging approaches are required to characterize and develop these resources. This Special Issue covers some of the technical challenges for developing unconventional energy sources from shale gas/oil, tight gas sand, and coalbed methane.

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.
