Book excerpt: As part of the effort being made to evaluate the CO2 storage potential of deep saline aquifers in Israel, the objective of this study is to evaluate the storage potential of the Lower aquifer in the Negev, which comprises Paleozoic - Triassic rocks of the Negev and Ramon groups. CO2 emission to the atmosphere is considered as one of the major reasons for climate change. One of the more feasible options for reducing CO2 emission from fossil fuels combustion is its capture and storage in porous rocks in the deep subsurface. Deep saline aquifers are considered to have the best potential for CO2 storage, for long periods of time. The most effective phase for CO2 to be stored in the subsurface is in its supercritical phase, when it has a density of liquid and viscosity of gas properties, and thus will allow better usage of the pore space, while keeping the easy injectivity of a gas. In order to have a better understanding of the petrophysical properties and the litho-facies of the studied section (Negev and Ramon groups), an in depth geological investigation of these layers has been carried, using petrophysical and petrographic data from boreholes. Based on these geological investigation a new reservoir has been defined here for storage purposes comprises the lowermost four formations of the Lower aquifer; Sa'ad, Arqov, Shezaf and Yamin formations called the "Permian" aquifer. The thermophysical conditions prevail in the Permian aquifer are suitable for CO2 storage in its super-critical phase throughout the entire study area. However, the large depth to the aquifer's top is one of the reasons for the scarcity of wellbores and seismic data in this section. This shortage of data triggered a geostatistical approach which has been implemented in this study and included examination of the variability in the calculated depth and thickness of the layers, caused by using different methods of spatial interpolations. In addition, a few sensitivity tests of several parameters controlling the temperature and pressure of the subsurface, and by that effecting the capacity assessments has been conducted, in order to determine the magnitude of error in the effective capacity calculation. Those examination yields that the difference in total capacity for CO2 storage between 6 interpolation methods is 2.4% and that an error in determining the depth parameter of the reservoir top yields an error of less than 1% in total capacity calculations. This study found that the minimum total capacity estimation for CO2 storage in the Permian aquifer is 1.53 Gt (Giga-Tonnes) which are 27% of the total future emissions of Israel for 50 years (2025-2075) and by that can't be regarded as the only storage solution for CO2. -- abstract.
Book Synopsis The Many Facets of Israel's Hydrogeology by : Uri Kafri
Download or read book The Many Facets of Israel's Hydrogeology written by Uri Kafri and published by Springer Nature. This book was released on 2020-11-09 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a collection of essays that address various facets of the hydrogeology of Israel. Despite its small geographic size, Israel exhibits a variety of climates and is located between two regional fluctuating base levels. The respective chapters discuss the variety of hydrogeological configurations and hydrological processes produced by these geographical circumstances. In some cases, the interpretation of these aspects is deliberately left open to debate, because the authors were asked to provide, in addition to their own views, also alternative and even conflicting ones. Hydrogeological configurations similar to those in Israel can be found in other countries around the world. Therefore, researchers, scholars and professionals in this interdisciplinary field can benefit from and directly apply the considerable experience and expertise that has been gathered in Israel over the past few decades.
Book Synopsis Geological Storage of CO2 in Deep Saline Formations by : Auli Niemi
Download or read book Geological Storage of CO2 in Deep Saline Formations written by Auli Niemi and published by Springer. This book was released on 2017-02-24 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers readers a comprehensive overview, and an in-depth understanding, of suitable methods for quantifying and characterizing saline aquifers for the geological storage of CO2. It begins with a general overview of the methodology and the processes that take place when CO2 is injected and stored in deep saline-water-containing formations. It subsequently presents mathematical and numerical models used for predicting the consequences of CO2 injection. This book provides descriptions of relevant experimental methods, from laboratory experiments to field scale site characterization and techniques for monitoring spreading of the injected CO2 within the formation. Experiences from a number of important field injection projects are reviewed, as are those from CO2 natural analog sites. Lastly, the book presents relevant risk management methods. Geological storage of CO2 is widely considered to be a key technology capable of substantially reducing the amount of CO2 released into the atmosphere, thereby reducing the negative impacts of such releases on the global climate. Around the world, projects are already in full swing, while others are now being initiated and executed to demonstrate the technology. Deep saline formations are the geological formations considered to hold the highest storage potential, due to their abundance worldwide. To date, however, these formations have been relatively poorly characterized, due to their low economic value. Accordingly, the processes involved in injecting and storing CO2 in such formations still need to be better quantified and methods for characterizing, modeling and monitoring this type of CO2 storage in such formations must be rapidly developed and refined.

Download or read book Potential Carbon Dioxide Storage Capacity of the Saline Portions of the Lower Cretaceous Aquifer System in the Plains CO2 Reduction Partnership Region written by James A. Sorensen and published by . This book was released on 2005 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large, Lower Cretaceous age, regional aquifer system underlies much of the central portion of the North American continent, including the Plains CO2 Reduction (PCOR) Partnership region. The Lower Cretaceous aquifer system is complex, but with respect to CO2 sequestration potential, it may be one of the most important aquifers in the region. Water quality varies greatly in the system, ranging from saline to fresh. Obviously only the saline parts of the formation would be considered for CO2 sequestration. The U.S. Geological Survey (USGS) and others recognize two discrete clastic aquifers within the Lower Cretaceous. They are separated throughout part of the PCOR Partnership area by shale. Where the shale is absent, the aquifers merge and are considered a single aquifer. This aquifer system has significant regional sequestration potential.

Download or read book Carbon Dioxide Capture for Storage in Deep Geologic Formations - Results from the CO2 Capture Project written by David C Thomas and published by Elsevier. This book was released on 2015-01-03 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, the prospect of climate change resulting from anthropogenic CO2 has become a matter of growing public concern. Not only is the reduction of CO2 emissions extremely important, but keeping the cost at a manageable level is a prime priority for companies and the public, alike. The CO2 capture project (CCP) came together with a common goal in mind: find a technological process to capture CO2 emissions that is relatively low-cost and able be to be expanded to industrial applications. The Carbon Dioxide Capture and Storage Project outlines the research and findings of all the participating companies and associations involved in the CCP. The final results of thousands of hours of research are outlined in the book, showing a successful achievement of the CCP’s goals for lower cost CO2 capture technology and furthering the safe, reliable option of geological storage. The Carbon Dioxide Capture and Storage Project is a valuable reference for any scientists, industrialists, government agencies, and companies interested in a safer, more cost-efficient response to the CO2 crisis.
Book Synopsis Mechanisms for CO2 Sequestration in Geological Formations and Enhanced Gas Recovery by : Roozbeh Khosrokhavar
Download or read book Mechanisms for CO2 Sequestration in Geological Formations and Enhanced Gas Recovery written by Roozbeh Khosrokhavar and published by Springer. This book was released on 2016-08-23 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives background information why shale formations in the world are important both for storage capacity and enhanced gas recovery (EGR). Part of this book investigates the sequestration capacity in geological formations and the mechanisms for the enhanced storage rate of CO2 in an underlying saline aquifer. The growing concern about global warming has increased interest in geological storage of carbon dioxide (CO2). The main mechanism of the enhancement, viz., the occurrence of gravity fingers, which are the vehicles of enhanced transport in saline aquifers, can be visualized using the Schlieren technique. In addition high pressure experiments confirmed that the storage rate is indeed enhanced in porous media. The book is appropriate for graduate students, researchers and advanced professionals in petroleum and chemical engineering. It provides the interested reader with in-depth insights into the possibilities and challenges of CO2 storage and the EGR prospect.
Book Synopsis CO2 Injection Into a Deep Saline Aquifer by : Michael John Gragg

Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenic levels of atmospheric greenhouse gases, particularly carbon dioxide (CO2) have increased rapidly over the last several decades and coincide with rising temperatures globally. One possible solution is to capture CO2 before it is released into the atmosphere by large point sources, such as fossil fuel power plants. Once captured, the CO2 can be condensed and transported to a storage facility. Of the available options for storage of condensed CO2, geologic sequestration in deep saline aquifers is considered the most viable option. Porosity measurements were obtained for nearly 100 core samples of the Knox and Stones River groups from the middle Tennessee area as part of a larger project for the Tennessee Division of Geology, characterizing the potential for geologic CO2 sequestration in Tennessee. Certain formations within these groups were found to exhibit higher porosity (higher storage potential) than others. Measured porosity values were quite low, ranging from 0.21 - 10.67 % with a median value of 1.21 %. These data can be used to aid in the decision making process concerning possible geologic targets for geologic CO2 sequestration in Tennessee. A sensitivity analysis was also performed using a numerical model for geologic carbon sequestration (STOMP). Intrinsic permeability, porosity, pore compressibility, the van Genuchten residual liquid saturation, [alpha] and m parameters, and the Brooks and Corey residual liquid and gas saturations were varied independently and their influence on CO2 storage was determined. Changes in costs based on the parameter variations were calculated to evaluate the relative importance of the various parameters. The most influential parameters were intrinsic permeability, the van Genuchten m parameter, and the Brooks and Corey residual gas saturation. These results highlight the need for accurate measurement of intrinsic permeability and capillary pressure saturation parameters in addition to more commonly measured properties like porosity.

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Many geoscientists endorse Carbon Capture and Storage (CCS) as a potential strategy for mitigating emissions of greenhouse gases. Deep saline aquifers have been reported to have larger CO2 storage capacity than other formation types because of their availability worldwide and less competitive usage. This work proposes an analytical model for screening potential CO2 storage sites and investigates injection strategies that can be employed to enhance CO2 storage. The analytical model provides of estimates CO2 storage efficiency, formation pressure profiles, and CO2-brine interface location. The results from the analytical model were compared to those from a sophisticated and reliable numerical model (TOUGH2). The models showed excellent agreement when input conditions applied in both were similar. Results from sensitivity studies indicate that the agreement between the analytical model and TOUGH2 strongly depends on irreducible brine saturation, gravity and on the relationship between relative permeability and brine saturation. A series of numerical experiments have been conducted to study the pros and cons of different injection strategies for CO2 storage in confined saline aquifers. Vertical, horizontal, and joint vertical and horizontal injection wells were considered. Simulations results show that horizontal wells could be utilized to improve CO2 storage capacity and efficiency in confined aquifers under pressure-limited conditions with relative permeability ratios greater than or equal to 0:01. In addition, joint wells are more efficient than single vertical wells and less efficient than single horizontal wells for CO2 storage in anisotropic aquifers.

Book excerpt: Storage of carbon dioxide is being actively considered for the reduction of green house gases. To make an impact on the environment CO2 should be put away on the scale of gigatonnes per annum. The storage capacity of deep saline aquifers is estimated to be as high as 1,000 gigatonnes of CO2.(IPCC). Published reports on the potential for sequestration fail to address the necessity of storing CO2 in a closed system. This work addresses issues related to sequestration of CO2 in closed aquifers and the risk associated with aquifer pressurization. Through analytical modeling we show that the required volume for storage and the number of injection wells required are more than what has been envisioned, which renders geologic sequestration of CO2 a profoundly nonfeasible option for the management of CO2 emissions unless brine is produced to create voidage and pressure relief. The results from our analytical model match well with a numerical reservoir simulator including the multiphase physics of CO2 sequestration. Rising aquifer pressurization threatens the seal integrity and poses a risk of CO2 leakage. Hence, monitoring the long-term integrity of CO2 storage reservoirs will be a critical aspect for making geologic sequestration a safe, effective and acceptable method for greenhouse gas control. Verification of long-term CO2 residence in receptor formations and quantification of possible CO2 leaks are required for developing a risk assessment framework. Important aspects of pressure falloff tests for CO2 storage reservoirs are discussed with a focus on reservoir pressure monitoring and leakage detection. The importance of taking regular pressure falloffs for a commercial sequestration project and how this can help in diagnosing an aquifer leak will be discussed. The primary driver for leakage in bulk phase injection is the buoyancy of CO2 under typical deep reservoir conditions. Free-phase CO2 below the top seal is prone to leak if a breach happens in the top seal. Consequently, another objective of this research is to propose a way to engineer the CO2 injection system in order to accelerate CO2 dissolution and trapping. The engineered system eliminates the buoyancy-driven accumulation of free gas and avoids aquifer pressurization by producing brine out of the system. Simulations for 30 years of CO2 injection followed by 1,000 years of natural gradient show how CO2 can be securely and safely stored in a relatively smaller closed aquifer volume and with a greater storage potential. The engineered system increases CO2 dissolution and capillary trapping over what occurs under the bulk phase injection of CO2. This thesis revolves around identification, monitoring and mitigation of the risks associated with geological CO2 sequestration.

Book Synopsis Underground Storage of Natural Gas by : M.R. Tek
Download or read book Underground Storage of Natural Gas written by M.R. Tek and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of NATO Advanced Study Institute, 'Underground Storage of Natural Gas - Theory and Practice', which was held at The Middle East Technical University, Ankara, Turkey during 2-10 May 1988. Underground storage is the process which effectively balances a variable demand market with a desirably constant supply provided by pipelines. Storage reservoirs are the unique warehouses designed and developed to provide a ready supply of natural gas in response to high, peak demands during cold weather. The natural' gas is injected into the underground storage environment when the market demand falls below the supply available from the pipeline. It is withdrawn from the storage reservoir to supplement the steady supply provided by the pipelines whenever the demand exceeds the supply. The overall wellbeing of the entire western world in general and of the NATO member count ries in particular depend critically upon having sufficient energy resources. Of over 80 quad Btus of energy consumed each year in the western world, about 30~ comes from natural gas, a figure only exceeded by oil. The technology related to supply and demand of natural gas has been in the focus of long range energy planning during the last decade in Western Europe. In view of recent developments related to natural gas in Europe and Turkey, an "Advanced Study Institute" programme in Turkey on underground storage of natural gas was deemed particularly relevant and timely.
