Geologic Characterization of the South Georgia Rift Basin for Source Proximal CO2 Storage

The project Geologic Characterization of the South Georgia Rift Basin for Source Proximal CO2 Storage is one of 9 site characterization projects that were implemented as part of ARRA (American Recovery and Reinvestment Act). Data from this project was used to improve resolution of data in NATCARB in the area of study. Data related to this study has already been incorporated in NATCARB Atlas. The South Carolina Research Foundation and partners evaluated the feasibility of CCS in the Jurassic/ Triassic (J / TR) saline formations of the buried Mesozoic South Georgia Rift (SGR) Basin that extends from South Carolina into Georgia. The J / TR sequence, based on preliminary assessment of limited geologic and geophysical data, appears to have both the appropriate areal extent and multiple horizons to permanently and safely store CO2 The presence of several igneous rock layers within the sequence may potentially provide adequate seals to prevent upward CO2 migration into the Coastal Plain aquifer systems. Approximately 81 kilometers of 2-D seismic reflection data were collected by Bay Geophysical, Inc. to explore a portion of the SGR located in southern Georgia. The 81 kilometers were divided into two lines approximately 40.5 kilometers each, with Line 1 intersecting Georgia well GGS 3457. Line 2 intersects Line 1 at the southern portion of Line 1 to maximize the extent of coverage away from GGS-3457 (a deep well drilled in the 1980s for oil and gas exploration). This well had a set of usable logs, including gamma and neutron logs that provided promising results related to CO2 storage. Results showed sandstone with porosity values greater than 10 percent and a thickness of 120 meters. The design of the seismic shot was to extrapolate information away from the well and to better define the extent of the SGR and the necessary reservoir and caprock for a successful CO2 injection. A numerical simulation model of CO2 Injection and migration was developed based on the geology log for the GGS-3457 well. The simulation model was used to investigate the feasibility of injecting 30 million metric tons of CO2 into SGR J / TA sediments and integrity of the diabase layers as seals to prevent CO2 migration.

Recovery Act: Understanding the Impact of CO 2 Injection on the Subsurface Microbial Community in an Illinois Basin CCS Reservoir: Integrated Student Training in Geoscience and Geomicrobiology

An integrated research and teaching program was developed to provide cross--disciplinary training opportunities in the emerging field of carbon capture and storage (CCS) for geobiology students attending the University of Illinois Urbana-Champaign (UIUC). Students from across the UIUC campus participated, including those from the departments of Geology, Microbiology, Biochemistry, Civil and Environmental Engineering, Animal Sciences and the Institute for Genomic Biology. The project took advantage of the unique opportunity provided by the drilling and sampling of the large-scale Phase III CCS demonstration Illinois Basin - Decatur Project (IBDP) in the central Illinois Basin at nearby Decatur, Illinois. The IBPD is under the direction of the Illinois State Geological Survey (ISGS, located on the UIUC campus) and the Midwest Geological Sequestration Consortium (MGSC). The research component of this project focused on the subsurface sampling and identification of microbes inhabiting the subsurface Cambrian-age Mt. Simon Sandstone. In addition to formation water collected from the injection and monitoring wells, sidewall rock cores were collected and analyzed to characterize the cements and diagenetic features of the host Mt. Simon Sandstone. This established a dynamic geobiological framework, as well as a comparative baseline, for future studies of how CO 2 injection might affect the deep microbial biosphere at other CCS sites. Three manuscripts have been prepared as a result of these activities, which are now being finalized for submission to top-tier international peer-reviewed research journals. The training component of this project was structured to ensure that a broad group of UIUC students, faculty and staff gained insight into CCS issues. An essential part of this training was that the UIUC faculty mentored and involved undergraduate and graduate students, as well as postdocs and research scientists, at all stages of the project in order to develop CCS-focused classroom and field courses, as well as seminars. This program provided an excellent opportunity for participants to develop the background necessary to establish longer-term research in CCS-related geology and microbial ecology. Further, the program provided an ongoing dynamic platform to foster long-term collaboration with the regional ISGS and MGSC sequestration partnership, while offering hands-on, applied learning experiences.

Leakage Risk Assessment of CO{sub 2} Transportation by Pipeline at the Illinois Basin Decatur Project, Decatur, Illinois

The Illinois Basin Decatur Project (IBDP) is designed to confirm the ability of the Mt. Simon Sandstone, a major regional saline-water-bearing formation in the Illinois Basin, to store 1 million tons of carbon dioxide (CO{sub 2}) injected over a period of three years. The CO{sub 2} will be provided by Archer Daniels Midland (ADM) from its Decatur, Illinois, ethanol plant. In order to transport CO{sub 2} from the capture facility to the injection well (also located within the ADM plant boundaries), a high-pressure pipeline of length 3,200 ft (975 m) has been constructed, running above the ground surface within the ADM plant footprint. We have qualitatively evaluated risks associated with possible pipeline failure scenarios that lead to discharge of CO{sub 2} within the real-world environment of the ADM plant in which there are often workers and visitors in the vicinity of the pipeline. There are several aspects of CO{sub 2} that make its transportation and potential leakage somewhat different from other substances, most notable is its non-flammability and propensity to change to solid (dry ice) upon strong decompression. In this study, we present numerical simulations using Computational Fluid Dynamics (CFD) methods of the release and dispersion of CO{sub 2} from individual hypothetical pipeline failures (i.e., leaks). Failure frequency of the various components of a pipeline transportation system over time are taken from prior work on general pipeline safety and leakage modeling and suggest a 4.65% chance of some kind of pipeline failure over the three-years of operation. Following the Precautionary Principle (see below), we accounted for full-bore leakage scenarios, where the temporal evolution of the mass release rate from the high-pressure pipeline leak locations was simulated using a state-of-the-art Pipe model which considers the thermodynamic effects of decompression in the entire pipeline. Failures have been simulated at four representative locations along the pipeline route within the ADM plant. Leakage scenarios at sites along the route of the pipeline, where plant operations (e.g., vehicular and train transportation) seem to present a higher likelihood of accidental failure, for example due to vehicles or equipment crashing into the pipeline and completely severing it, were modeled by allowing them to have a double source consistent with the pipeline releasing high-pressure CO{sub 2} from both ends of the broken pipe after a full-bore offset rupture. Simulation results show that the built environment of the plant plays a significant role in the dispersion of the gas as leaking CO{sub 2} can impinge upon buildings and other infrastructure. In all scenarios simulated, the region of very high-concentration of CO{sub 2} is limited to a small area around the pipeline failure, suggesting the likelihood of widespread harmful CO{sub 2} exposure to plant personnel from pipeline leakage is low. An additional risk is posed by the blast wave that emanates from a high-pressure pipeline when it is breached quickly. We estimate the blast wave risk as low because it occurs only for a short time in the immediate vicinity of the rupture, and requires an instantaneous large-scale rupture to occur. We recommend consideration of signage and guard rails and posts to mitigate the likelihood of vehicles crashing into the pipeline. A standardized emergency response plan applicable to capture plants within industrial sites could be developed based on the IBDP that would be useful for other capture plants. Finally, we recommend carrying out coupled wellbore-reservoir blowout scenario modeling to understand the potential for hazardous conditions arising from an unexpected blowout at the wellhead.

Radionuclide inventories for the F- and H-area seepage basin groundwater plumes

Within the General Separations Areas (GSA) at the Savannah River Site (SRS), significant inventories of radionuclides exist within two major groundwater contamination plumes that are emanating from the F- and H-Area seepage basins. These radionuclides are moving slowly with groundwater migration, albeit more slowly due to interaction with the soil and aquifer matrix material. The purpose of this investigation is to quantify the activity of radionuclides associated with the pore water component of the groundwater plumes. The scope of this effort included evaluation of all groundwater sample analyses obtained from the wells that have been established by the Environmental Compliance & Area Completion Projects (EC&ACP) Department at SRS to monitor groundwater contamination emanating from the F- and H-Area Seepage Basins. Using this data, generalized groundwater plume maps for the radionuclides that occur in elevated concentrations (Am-241, Cm-243/244, Cs-137, I-129, Ni-63, Ra-226/228, Sr-90, Tc-99, U-233/234, U-235 and U-238) were generated and utilized to calculate both the volume of contaminated groundwater and the representative concentration of each radionuclide associated with different plume concentration zones.

Geomechanical Characterization and Modeling of the Newark Basin

To ensure long-term safety and containment during geologic carbon sequestration operations, understanding reservoir and cap rock behavior under increased pressure conditions is essential. In particular, the risk of induced seismicity has recently emerged as one of the largest concerns for geologic carbon sequestration and other injection operations. Little observational data are available about induced seismicity risks from carbon dioxide injection. However, an increasing number of earthquakes in the continental United States and worldwide are being attributed to human activities that involve other types of underground injection. Analysis of these events suggests that the net injected volume is one of the key factors, and a prolonged injection of large volumes of carbon dioxide is projected to have high potential for triggering similar seismic events. Increased pore pressure may activate an existing critically stressed discontinuity by reducing its frictional resistance to slip, and cause cap rock failure. Even when facture slip does not produce large seismic events felt by humans or cause visible damage, it can increase formation permeability and compromise cap rock integrity, thus increasing the risk of leakage. The Geomechanical Properties of Mesozoic Basins project performed unique research in the Newark Basin by combining detailed laboratory characterization and rock core testing with novel field operations performed on wireline to measure in-situ stress conditions.

Central Appalachian Basin CarbonSAFE Integrated Pre-Feasibility Project (Final Technical Report)

The Central Appalachian Basin-Carbon Storage Assurance Facility Enterprise (CarbonSAFE) (CAB-CS) Integrated Prefeasibility Project identified several “Selected Areas” in eastern Ohio where the Cambrian-Ordovician age sandstones and carbonates show the most promising reservoir potential for carbon capture and storage (CCS). These selected areas are located near depleted oil and gas fields where oil recovery could be improved with enhanced oil recovery. This region has many large carbon dioxide (CO 2 ) point sources that represent a diverse array of industries, including coal-fired power plants, natural gas processing, refineries, chemical plants, and natural gas power. In a carbon-constrained future, one of the most promising ways to make coal a viable fuel option for power generation or industrial processes is to capture and store CO 2 emissions. The project is a pre-feasibility study to mitigate the emissions from 1.67 million metric tons CO 2 per year by developing a storage complex capable of storing 50 million metric tons. The pre-feasibility study identified two candidate locations for a carbon storage hub in the Appalachian Basin, analyzed six source-sink scenarios in the CAB-CS study area with analysis of capture and transport, defined infrastructure needs for a CCS project in the area, conducted an economic, liability, and social assessment, and built a team to evaluate CCS options in the CAB-CS study area. The project was an important step in implementing CCS in the CAB-CS study area. Major accomplishments include experience in investigating CCS projects in the area (learning by doing), adding to National Energy Technology Laboratory (NETL) best practices tools and tool sets, and building the elements of the CCS road map for the region.

Play Fairway Analysis: Structurally Controlled Geothermal Systems in the Eastern Great Basin Extensional Regime, Utah

A research team with membership from the University of Utah/Energy & Geoscience Institute, the University of Utah/Dept. of Geology & Geophysics, and the Utah Geological Survey, undertook a play fairway analysis (PFA) for geothermal resources in the Eastern Great Basin (EGB) extensional tectonic regime of western Utah. This is a high-priority region for geothermal exploration because active Basin and Range (B&R) extension with volcanism having a N-S strike is superimposed upon pre-existing E-W belts of plutonic rocks and large-scale structural lineaments. Cumulative heat flow along the N-S strike of the state totals approximately 5 GWt above background stable interior. Three electricity producing power plants currently exist with substantial potential for increase. Succinctly, our PFA approach aims to resolve potential sources of heat and permeability in the region, which are the two principal criteria for establishing a geothermal resource. An initial Phase 1 was carried out using only existing geoscientific data in the area. Criteria selected for focusing heat potential include direct heat flow measurements in boreholes, magnetotelluric (MT) low resistivity anomalies, fluid/gas geochemistry, and proximity to recent volcanic eruptions. Permeability is established through geological structures (fault density, critically stressed areas, seismicity, gravity), and MT low resistivity anomalies. In Phase II of this PFA project, additional geological, geophysical and geochemical data were acquired and analysis carried out primarily over promising composite common risk (CCR) areas initially identified in Phase I in order to focus prospectivity and prepare for drilling recommendations. These prospects are near the Twin Peaks rhyolite field, high heat flow areas north of the producing Cove Fort system, and geophysical structure beneath the Crater Knoll area off the northeast flank of the Mineral Mountains. Additional data included MT site fill-in, structural mapping and analysis using high-resolution imagery, gravity and on-ground mapping, Nodal 3C passive seismic collection, and passive 3He surveying. Heat source and permeability potential are again expressed in terms of their individual common risk segment (CRS) maps, with a color scheme using green for most favorable (low risk) and red for least favorable (high risk). Diverse data types are united through the technique of probability kriging, which establishes prospectivity thresholds for each data type and then computes probability of exceeding that threshold over the PFA area. Modified CRS and CCRS maps are compared to those of Phase I to highlight tighter prospectivity focus. In doing so, the prospectivity threshold for heat was increased significantly to narrow the targeting. In the final Phase III of this project where a recommended deep thermal gradient hole was sited, additional geophysical, geochemical and geological field collection and analysis was carried out to refine drill hole targeting. This includes prospect-scale MT, gravity, structure, passive seismic deployment (Cove Fort area), and detailed 3He isotope profiling. It was the recommendation of the DOE Technical Monitoring Team (TMT) that one or more holes be sited in the north-ern Cove Fort area where legacy TG gradient holes showed high cumulative heat flow. These were to be of moderate depth, 2000-3000 feet, to reach the geothermal fluid table expected to start in excess of 1000 feet depth. The drilling organization stipulated by the DOE/GTO was that of the USGS Research Drilling Program (RDP) centered in Las Vegas, NV. A detailed well plan, appended to this report, was developed principally by Dr. Ben Barker consulting to University of Utah, Dr. Steve Pye on the DOE TMT, Mr. Steven Crawford of the USGS-RDP, and the project PI Phil Wannamaker. However, temperature and possible H 2 S at the systems lead to cancellation of the drilling last-minute as this appeared outside the experience base of the USGS-RDP. We hope to have the opportunity to revisit the test drilling and expand the Play Fairway Analysis of this region at some point in the future.

An Assessment of Geologic Carbon Sequestration Options in the Illinois Basin: Phase III

The Illinois Basin – Decatur Project (IBDP) successfully demonstrated the safe geologic storage of carbon dioxide (CO 2 ) at the near commercial-scale. Such demonstration projects are essential to gain understanding of the workflows and monitoring equipment needed to be able to geologically sequester CO 2 at a commercial scale, and to gain public confidence in the technology. The IBDP was carried out by the Midwest Geological Sequestration Consortium (MGSC), one of seven USDOE NETL RCSPs that were formed to evaluate the safety and effectiveness of geological storage of CO 2 as a mitigation tool to address global climate change. The MGSC was formed and led by the Illinois, Indiana, and Kentucky geological surveys of the Illinois Basin. The Illinois State Geological Survey (ISGS) at the University of Illinois was the principal investigator for and managed the IBDP, with the Indiana Geological Survey (IGS) (now Indiana Geological and Water Survey) and the Kentucky Geological Survey (KGS) as key partners.
