Book Description
Analyses suggest that carbon dioxide (CO2) can be injected into depleted gas reservoirs to enhance methane (CH4) recovery for periods on the order of 10 years, while simultaneously sequestering large amounts of CO2. Simulations applicable to the Rio Vista Gas Field in California show that mixing between CO2 and CH4 is slow relative to repressurization, and that vertical density stratification favors enhanced gas recovery.

Book Description
Natural gas reservoirs are obvious targets for carbon sequestration by direct carbon dioxide (CO2) injection by virtue of their proven record of gas production and integrity against gas escape. Carbon sequestration in depleted natural gas reservoirs can be coupled with enhanced gas production by injecting CO2 into the reservoir as it is being produced, a process called Carbon Sequestration with Enhanced Gas Recovery (CSEGR). In this process, supercritical CO2 is injected deep in the reservoir while methane (CH4) is produced at wells some distance away. The active injection of CO2 causes repressurization and CH4 displacement to allow the control and enhancement of gas recovery relative to water-drive or depletion-drive reservoir operations. Carbon dioxide undergoes a large change in density as CO2 gas passes through the critical pressure at temperatures near the critical temperature. This feature makes CO2 a potentially effective cushion gas for gas storage reservoirs. Thus at the end of the CSEGR process when the reservoir is filled with CO2, additional benefit of the reservoir may be obtained through its operation as a natural gas storage reservoir. In this paper, we present discussion and simulation results from TOUGH2/EOS7C of gas mixture property prediction, gas injection, repressurization, migration, and mixing processes that occur in gas reservoirs under active CO2 injection.

Book Description
Increasing energy demand combined with public concern for the environment obligates the oil industry to supply oil and natural gas to the public while minimizing the carbon footprint due to its activities. Today, fossil fuels are essential in meeting the global energy needs, but have the undesirable outcome of producing carbon dioxide. Carbon dioxide (CO2) injection in reservoirs is an appealing Enhanced Oil/Gas Recovery method for increasing hydrocarbon production by using the miscible interactions between hydrocarbon and carbon dioxide. Carbon dioxide flooding is beneficial to the environment and to petroleum producers, since it can store carbon dioxide while increasing oil and natural gas production. A practical challenge in combining CO2 Sequestration with Enhanced Gas Recovery (EGR) is determining the optimal process parameters that maximize the project value. This research describes the development of a procedure to determine the best process conditions for the CO2 EGR and Sequestration process. Analysis includes experimental work that illustrates that CO2 is able to reduce the dew point pressure of wet gas fluids and that reservoir fluid phase changes can be indicated by changes in total fluid compressiblity. In addition, compositional simulation illustrates that CO2 improves condensate and natural gas recovery. Studies show that the ideal reservoir management strategy for CO2 EGR is to set the CO2 injectors' bottom hole pressure to the initial reservoir pressure. An economic model is developed that illustrates the capital investment necessary for the CO2 EGR and Sequestration process for different capture technologies and levels of captured CO2 impurity. This economic model is utilized in conjunction with an optimization algorithm to illustrate the potential profitability of theCO2 EGR and Sequestration project. To illustrate the economic risk associated with CO2 EGR and Sequestration project, probabilistic analysis is used to illustrate scenarios where the technology is successful. This work is applicable to carbonate wet gas reservoirs that have significant gas production problems associated with condensate blockage. This work is also useful in modeling the economics associated with CO2 EGR and CO2 Sequestration. The strategy developed in this work is applicable to designing process conditions that correspond to optimal CO2 EGR and optimal CO2 Sequestration.

Book Description
Compiled from a conference on this important subject by three of the most well-known and respected editors in the industry, this volume provides some of the latest technologies related to carbon capture, utilization and, storage (CCUS). Of the 36 billon tons of carbon dioxide (CO2) being emitted into Earth's atmosphere every year, only 40 million tons are able to be captured and stored. This is just a fraction of what needs to be captured, if this technology is going to make any headway in the global march toward reversing, or at least reducing, climate change. CO2 capture and storage has long been touted as one of the leading technologies for reducing global carbon emissions, and, even though it is being used effectively now, it is still an emerging technology that is constantly changing. This volume, a collection of papers presented during the Cutting-Edge Technology for Carbon Capture, Utilization, and Storage (CETCCUS), held in Clermont-Ferrand, France in the fall of 2017, is dedicated to these technologies that surround CO2 capture. Written by some of the most well-known engineers and scientists in the world on this topic, the editors, also globally known, have chosen the most important and cutting-edge papers that address these issues to present in this groundbreaking new volume, which follows their industry-leading series, Advances in Natural Gas Engineering, a seven-volume series also available from Wiley-Scrivener. With the ratification of the Paris Agreement, many countries are now committing to making real progress toward reducing carbon emissions, and this technology is, as has been discussed for years, one of the most important technologies for doing that. This volume is a must-have for any engineer or scientist working in this field.

Book Description
Fossil fuels still need to meet the growing demand of global economic development, yet they are often considered as one of the main sources of the CO2 release in the atmosphere. CO2, which is the primary greenhouse gas (GHG), is periodically exchanged among the land surface, ocean, and atmosphere where various creatures absorb and produce it daily. However, the balanced processes of producing and consuming the CO2 by nature are unfortunately faced by the anthropogenic release of CO2. Decreasing the emissions of these greenhouse gases is becoming more urgent. Therefore, carbon sequestration and storage (CSS) of CO2, its utilization in oil recovery, as well as its conversion into fuels and chemicals emerge as active options and potential strategies to mitigate CO2 emissions and climate change, energy crises, and challenges in the storage of energy.

Book Description
The United States produces over seventy percent of all its electricity from fossil fuels and nearly fifty percent from coal alone. Worldwide, forty-one percent of all electricity is generated from coal, making it the single most important fuel source for electricity generation, followed by natural gas. This means that an essential part of any portfolio for emissions reduction will be technology to capture carbon dioxide and permanently sequester it in suitable geologic formations. While many nations have incentivized development of CCS technology, large regulatory and legal barriers exist that have yet to be addressed. This book identifies current law and regulation that applies to geologic sequestration in the U.S., the regulatory needs to ensure that geologic sequestration is carried out safely and effectively, and barriers that current law and regulation present to timely deployment of CCS. The authors find the three most significant barriers to be: an ill-defined process to access pore space in deep saline formations; a piecemeal, procedural, and static permitting system; and the lack of a clear, responsible plan to address long-term liability associated with sequestered CO2. The book provides legislative options to remove these barriers and address the regulatory needs, and makes recommendations on the best options to encourage safe, effective deployment of CCS. The authors operationalize their recommendations in legislative language, which is of particular use to policymakers faced with the challenge of addressing climate change and energy.

Book Description
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.

Book Description
Carbon capture and storage (CCS) is the process of capturing carbon dioxide (CO2) prior to its being emitted into the atmosphere, then either using it in a commercial application or storing it in geological formations for hundreds to thousands of years. If policies aimed at large reductions of CO2 emissions from industrial sources and power plants are enacted, more CCS will be needed. RAND researchers explored the ability of the industrial base supporting the transportation and storage of CO2 to expand, assessing the industrial base for transportation and injection for CO2 for both geologic storage and enhanced oil recovery. They also identified and quantified the activities, equipment, and labor required for transporting CO2 to an injection site, using it in oil recovery, and storing it in a geologic formation. RAND developed four scenarios for future CCS development and determined that under most of them, significant expansion of geologic storage capacity is required after 2025, and that based on current activities, it appears that the industrial base supporting the development of geologic storage has the ability to meet increased needs for CO2 storage.
