Available in PDF, EPUB and Kindle. Book excerpt: Many geological, geochemical, geomechanical and hydrogeological factors control CO2 storage in subsurface. Among them heterogeneity in saline aquifer can seriously influence design of injection wells, CO2 injection rate, CO2 plume migration, storage capacity, and potential leakage and risk assessment. This study applies indicator geostatistics, transition probability and Markov chain model at the Rock Springs Uplift, Wyoming generating facies-based heterogeneous fields for porosity and permeability in target saline aquifer (Pennsylvanian Weber sandstone) and surrounding rocks (Phosphoria, Madison and cap-rock Chugwater). A multiphase flow simulator FEHM is then used to model injection of CO2 into the target saline aquifer involving field-scale heterogeneity. The results reveal that (1) CO2 injection rates in different injection wells significantly change with local permeability distributions; (2) brine production rates in different pumping wells are also significantly impacted by the spatial heterogeneity in permeability; (3) liquid pressure evolution during and after CO2 injection in saline aquifer varies greatly for different realizations of random permeability fields, and this has potential important effects on hydraulic fracturing of the reservoir rock, reactivation of pre-existing faults and the integrity of the cap-rock; (4) CO2 storage capacity estimate for Rock Springs Uplift is 6614 ± 256 Mt at 95% confidence interval, which is about 36% of previous estimate based on homogeneous and isotropic storage formation; (5) density profiles show that the density of injected CO2 below 3 km is close to that of the ambient brine with given geothermal gradient and brine concentration, which indicates CO2 plume can sink to the deep before reaching thermal equilibrium with brine. Finally, we present uncertainty analysis of CO2 leakage into overlying formations due to heterogeneity in both the target saline aquifer and surrounding formations. This uncertainty in leakage will be used to feed into risk assessment modeling.

Book Synopsis Geomechanical Characterization of CO2 Storage Reservoirs on the Rock Springs Uplift, WY by : Hua Yu
Download or read book Geomechanical Characterization of CO2 Storage Reservoirs on the Rock Springs Uplift, WY written by Hua Yu and published by . This book was released on 2018 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon sequestration in deep geological formations has been considered as an important and practical solution to significantly reduce the CO2 emission. CO2 injection into reservoirs may lead to mechanical, chemical, and hydrological effects on the geological formations. This Ph.D. research primarily focuses on quantifying and analyzing geomechanical properties and the effect of CO2 on geomechanical properties of reservoir rocks. The research includes: 1) select and prepare rock samples (Weber Sandstone) from Rock Springs Uplift, Wyoming; 2) design and conduct geomechanical experiments; 3) improve the estimations of geomechanical properties of rocks; 4) develop the analytical model describing the nonlinear rock failure behavior; 5) investigate the effect of compliant pores on reservoir rocks under different stress states; 6) quantify and analyze the changes in geomechanical properties of reservoir rocks due to CO2. Major conclusions drawn from this research were summarized. First, a new method proposed for estimating elastic constants and crack propagation stress thresholds significantly eliminates bias due to both user-defined data interval and poor data resolution on the stress-strain data analysis procedures. Second, a generalized power-law failure criterion was derived in terms of the rock strength properties and validated through published test data for different rock types. Third, the nonlinear pore pressure-volumetric strain relationship at low confining pressure changes to a linear behavior at high confining pressure. Fourth, the unstable crack growth region governed by the initial compliant porosity is independent of the differential pressure. Fifth, the effect of CO2 on geomechanical properties of Weber Sandstone in the linear elastic, nonlinear plastic, and post-failure regime is limited. However, a consistent change in Mohr failure coefficients due to CO2 was observed.

Book Synopsis Management of Displaced Waters from Geological Carbon Dioxide (CO2) Sequestration Within the Wyoming Rock Springs Uplift by : Xuan He
Download or read book Management of Displaced Waters from Geological Carbon Dioxide (CO2) Sequestration Within the Wyoming Rock Springs Uplift written by Xuan He and published by . This book was released on 2011 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The geological CO2 sequestration project at the Wyoming Rock Springs Uplift site is anticipated to result in the injection of 127.5 million tonnes (1.7 million tonnes per year) of CO2 per well into the Tensleep/Weber Sandstone and Madison Limestone formations over a 75 year period (Surdam et al., 2009). Large amounts of water must be extracted from the formations in order to maintain reservoir forces under fracture pressure limits. Sequestration of CO2 within the two aquifers would require approximately 75 million tonnes (1 million tonnes per year) of saline water to be removed from the reservoirs. An obvious challenge for this project is to determine how to manage the displaced water in order to prevent adverse environmental impacts. Therefore, the potential impacts of the displaced water on surface waters, soils, and vegetation ecosystems, where large amounts of displaced waters are utilized, were assessed in this study. Water treatment technologies were investigated to determine possible processes that might be implemented to reduce the salt content of the displaced water that would allow for other uses. Reverse osmosis (RO) and multi-stage flash (MSF) processes were considered the most promising desalination technologies, with RO more cost-efficient compared to MSF based on historical data. Consequently, it is imperative that possible scenarios be developed whereby the treated waters can be utilized for beneficial uses, which include: industrial--power plants or water treatment plants, oil and gas industry, and soda ash production; agricultural--irrigation and livestock; ecological--enhanced in-stream flow or fisheries, wetlands or artificial wetlands, injection for aquifer storage or recovery and recreation areas; domestic--drinking water, dust abasement, fire-fighting and vehicles wash; and others--mineral extraction.
Book Synopsis CO2-enhanced Water Recovery Through Integrated CO2 Injection and Brine Extraction in the Rock Springs Uplift Formation in Southwest, WY by : Kelsey A. Hunter
Download or read book CO2-enhanced Water Recovery Through Integrated CO2 Injection and Brine Extraction in the Rock Springs Uplift Formation in Southwest, WY written by Kelsey A. Hunter and published by . This book was released on 2017 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: CO2-EWR is modeled by integrating the Finite Element Heat and Mass Transfer code (fehm.lanl.gov) to simulate the flow of CO2 and brine within the reservoir and a well model to connect the properties of CO2 and brine at the surface to the properties in the reservoir. The integrated consideration of the two models determines optimal combinations of CO2 injection and brine extraction rates and identifies relationships dictated by the injection and storage of CO2 and brine extraction. I modeled CO2-EWR in the Rock Springs Uplift (RSU) formation in southwest Wyoming and controlled the rates of CO2 injection and brine extraction in order to understand the physical tradeoffs that affect the pressure evolution, CO2 storage capabilities, and CO2 Area of Review (AoR) in the aquifer.

This book was released on 2013 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developing effective management strategies for greenhouse gases, such as carbon dioxide (CO2), is receiving growing interest as concerns over their role(s) in affecting global climate change develop. Geologic sequestration has been identified as one possible avenue for storing CO2, which would otherwise have been discharged to the atmosphere. The Rock Springs Uplift (RSU) in southwestern Wyoming has been identified as a candidate site for geologic sequestration of CO2. The RSU site contains two deep saline aquifers into which CO2 can be injected and stored: The Weber Sandstone and Upper Madison Limestone Formations. Sequestration of CO2 into these two formations is expected to displace approximately 700,000 gallons per day of highly saline water (avg. total dissolved solids ~95,000 mg L−1). For geologic sequestration to be successful, or even a practical option at the RSU site, the displaced water must be managed in such a way so that the carbon balance (CO2 sequestered - CO2 produced during treatment) is favorable and economics affordable. Three distinct water treatment alternatives were developed for managing and facilitating the beneficial reuse of the displaced water at the RSU site and included: desalination using forward osmosis, desalination using mechanical distillation and disposal using wind-aided evaporation. A present worth cost calculation for each alternative was developed which included the capital cost and the yearly operation and maintenance cost. The carbon footprint expected from each alternative was also evaluated. Both the present worth cost and carbon footprint should be considered when determining the most appropriate treatment alternative for this water.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Under this project, a multidisciplinary team of researchers at the University of Wyoming combined state-of-the-art experimental studies, numerical pore- and reservoir-scale modeling, and high performance computing to investigate trapping mechanisms relevant to geologic storage of mixed scCO2 in deep saline aquifers. The research included investigations in three fundamental areas: (i) the experimental determination of two--phase flow relative permeability functions, relative permeability hysteresis, and residual trapping under reservoir conditions for mixed scCO2--brine systems; (ii) improved understanding of permanent trapping mechanisms; (iii) scientifically correct, fine grid numerical simulations of CO2 storage in deep saline aquifers taking into account the underlying rock heterogeneity. The specific activities included: (1) Measurement of reservoir--conditions drainage and imbibition relative permeabilities, irreducible brine and residual mixed scCO2 saturations, and relative permeability scanning curves (hysteresis) in rock samples from RSU; (2) Characterization of wettability through measurements of contact angles and interfacial tensions under reservoir conditions; (3) Development of physically--based dynamic core--scale pore network model; (4) Development of new, improved high-- performance modules for the UW--team simulator to provide new capabilities to the existing model to include hysteresis in the relative permeability functions, geomechanical deformation and an equilibrium calculation (Both pore-- and core--scale models were rigorously validated against well--characterized core-- flooding experiments); and (5) An analysis of long term permanent trapping of mixed scCO2 through high--resolution numerical experiments and analytical solutions. The analysis takes into account formation heterogeneity, capillary trapping, and relative permeability hysteresis.

This book was released on 2013 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study, funded by U.S. Department of Energy National Energy Technology Laboratory award DE-FE0002142 along with the state of Wyoming, uses outcrop and core observations, a diverse electric log suite, a VSP survey, in-bore testing (DST, injection tests, and fluid sampling), a variety of rock/fluid analyses, and a wide range of seismic attributes derived from a 3-D seismic survey to thoroughly characterize the highest-potential storage reservoirs and confining layers at the premier CO2 geological storage site in Wyoming. An accurate site characterization was essential to assessing the following critical aspects of the storage site: (1) more accurately estimate the CO2 reservoir storage capacity (Madison Limestone and Weber Sandstone at the Rock Springs Uplift (RSU)), (2) evaluate the distribution, long-term integrity, and permanence of the confining layers, (3) manage CO2 injection pressures by removing formation fluids (brine production/treatment), and (4) evaluate potential utilization of the stored CO2.

Download or read book Numerical Modeling and Simulation of Carbon Dioxide Storage Capacity of the Moxa Arch Site, Southwestern Wyoming written by Cheng Zhang and published by . This book was released on 2012 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the Moxa Arch geological CO2 sequestration project is to assess the geological CO2 storage capacity of saline aquifers in the Pennsylvanian Weber Sandstone in southwestern Wyoming. A 3-D seismic survey was selected and a fine-scale geological model was developed based on the integration of seismic interpretation, outcrop mapping, and other available information. The preliminary results from numerical simulations of CO2 storage scenarios were presented. The two goals of the simulation study were as follows: optimize the CO2 sequestration strategy within geological constraints, and examines the long-term fate of CO2 stored in this formation. Commercial numerical simulators and research simulators are used in the simulation study, and calibrated simulation results from the research simulators with those from the commercial simulator, usually a robust approach. The new research results and on-site observations were integrated into the research simulator for specific examination of CO2 sequestration and storage at site.

Book Synopsis Seismic Reservoir Modeling by : Dario Grana
Download or read book Seismic Reservoir Modeling written by Dario Grana and published by John Wiley & Sons. This book was released on 2021-05-04 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seismic reservoir characterization aims to build 3-dimensional models of rock and fluid properties, including elastic and petrophysical variables, to describe and monitor the state of the subsurface for hydrocarbon exploration and production and for CO2 sequestration. Rock physics modeling and seismic wave propagation theory provide a set of physical equations to predict the seismic response of subsurface rocks based on their elastic and petrophysical properties. However, the rock and fluid properties are generally unknown and surface geophysical measurements are often the only available data to constrain reservoir models far away from well control. Therefore, reservoir properties are generally estimated from geophysical data as a solution of an inverse problem, by combining rock physics and seismic models with inverse theory and geostatistical methods, in the context of the geological modeling of the subsurface. A probabilistic approach to the inverse problem provides the probability distribution of rock and fluid properties given the measured geophysical data and allows quantifying the uncertainty of the predicted results. The reservoir characterization problem includes both discrete properties, such as facies or rock types, and continuous properties, such as porosity, mineral volumes, fluid saturations, seismic velocities and density. Seismic Reservoir Modeling: Theory, Examples and Algorithms presents the main concepts and methods of seismic reservoir characterization. The book presents an overview of rock physics models that link the petrophysical properties to the elastic properties in porous rocks and a review of the most common geostatistical methods to interpolate and simulate multiple realizations of subsurface properties conditioned on a limited number of direct and indirect measurements based on spatial correlation models. The core of the book focuses on Bayesian inverse methods for the prediction of elastic petrophysical properties from seismic data using analytical and numerical statistical methods. The authors present basic and advanced methodologies of the current state of the art in seismic reservoir characterization and illustrate them through expository examples as well as real data applications to hydrocarbon reservoirs and CO2 sequestration studies.

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.

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

Download or read book Analysis of Triassic Formations as Potential Confining Units for Carbon Sequestration in Southwestern Wyoming written by Lynsey J. Spaeth and published by . This book was released on 2015 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon capture and storage locations are being investigated throughout the state of Wyoming, USA, in preparation for sequestration of greenhouse gases. At potential storage sites, confining units must be identified that are capable of ensuring stored carbon dioxide remains in place at depth. An investigation of the Triassic Thaynes and Dinwoody formations was conducted to evaluate confining potential on the Rock Springs Uplift (RSU). Analyzing a known seal, the Thaynes Formation, using data from core, petrographic sections, and strontium isotopes aided in identifying characteristics of confining units. The Thaynes Formation was used as an analogue to investigate the confining potential of the Dinwoody Formation including outcrop, core, petrographic section, and stable isotope data that were used to confirm depositional setting. Triaxial and mercury injection capillary pressure tests were conducted to reveal the maximum accommodation strain and minimum and maximum carbon dioxide column heights. Data suggest the Dinwoody Formation can accommodate large quantities of carbon dioxide but further investigation of the unit and modeling is suggested before injection on the RSU.
