SECARB Annual Report on In-Situ Monitoring Program

The Southeast Carbon Sequestration Partnership Phase III Anthropogenic Test at Citronelle Field is the United States’ largest prototype of commercial CO 2 capture from a coal-fired power station and transportation, injection, storage and monitoring. This report details the results of the background and first year of injection monitoring results for the Anthropogenic Test. Monitoring methods include both direct and indirect measurements. The Class V Experimental Permit requires extensive monitoring of injected CO 2 at the surface and at deep and shallow depths. The safety, integrity and information objectives of the CO 2 monitoring plan are in place to: (1) create and sustain wellbore integrity; (2) assure safe CO 2 injection operations; 3) verify the location and migration of the injected CO 2 plume; and (4) monitor for any CO 2 leakage. A robust suite of monitoring approaches are utilized for the in-situ monitoring and include, pressure monitoring, various seismic surveys, pulsed neutron logging, reservoir fluid sampling and injection surveys. Data and observations collected using these monitoring methods will be used in the numerical model to inform the post-injection site care monitoring plan.

Inject and Store from 33,000 up to 182,500 metric tons of CO 2 (2014) (SECARB Phase III Work Product 8.2.2.c)

The Southeast Regional Carbon Sequestration Partnership’s (SECARB’s) Anthropogenic Test is a demonstration of the deployment of CO 2 capture, transport, geologic storage, and monitoring technologies. The capture component of the test takes place at the James M. Barry Electric Generating Plant in Bucks, Alabama. The capture facility utilizes post-combustion amine capture technology licensed from Mitsubishi Heavy Industries America to process flue gas from a coal-fired power unit at Plant Barry. The amount of CO 2 captured using this process is equivalent to the emissions produced when generating 25 megawatts (MW) of electricity. CO 2 captured at the plant is transported by pipeline for underground storage in a saline geologic formation within the Citronelle Dome. This project is one of the first and the largest fully-integrated commercial prototype coal-fired carbon capture and storage projects in the USA. The material in this report is intended for general information only.

Southeast Carbon Sequestration Partnership (SECARB) Phase III Anthropogenic Test at Citronelle Field, Mobile Co., AL Surface and Shallow Subsurface Monitoring

The Southeast Carbon Sequestration Partnership Phase III Anthropogenic Test at Citronelle Field is one of the United States’ largest demonstrations of CO 2 capture, transportation, injection, storage and monitoring using CO 2 derived from a coal-fired electric generating unit. This report summarizes the background and initial injection phase groundwater and soil flux monitoring results. The purpose of the groundwater monitoring program, as prescribed in the Underground Injection Control (UIC) permits is to assure that the project’s activities do not harm Underground Sources of Drinking Water (USDWs). In particular, the objective of the program is to monitor for the release of injected CO2 into groundwater aquifers at the project site. Three shallow USDW monitoring wells were installed as part of the groundwater monitoring program. In addition, a water supply well located near the project’s deep characterization well was utilized for monitoring. Seventeen metals, general chemistry and field parameters (e.g. pH, specific conductance, turbidity) were sampled three times prior to injection and quarterly during the injection period to date. Changes in groundwater geochemistry potentially attributable to a release of carbon dioxide into the USDW from the injection activities are decreasing pH and increasing TIC. The change in pH may also accompany the mobilization of certain metals within the groundwater, but the changes are likely site-specific, based on the natural aquifer mineralogy (Wilkin and Diguilio, 2010). At this time, no downward trends for pH and increasing trends for TIC have been statistically determined in the monitor wells. Valid detections exceeding both the UIC discharge limit and the range of background concentrations observed as of the N=11 event include: Exceedance of the UIC permit discharge limit of manganese at D-9-7 MW-2S and D-9-9 MW-1, and exceedance of the UIC permit discharge limit of iron at D-9-9 MW-1. In addition, a statistically significant increase of barium and manganese has been observed at D-9-9 MW-1. However, Additional lines of evidence (namely, expected shifts in TIC or pH, per the research cited above) to interpret the cause (e.g., potential carbon dioxide influence) of the statistically determined exceedances and/or increases are absent at this time. Quarterly groundwater sampling and analysis will continue throughout the project. The UIC permit requires that soil CO 2 flux shall be monitored at the land surface at the injection site and at nearby locations. Twelve locations were chosen for surveys including a mix of near wellbore and offset locations. To date, 24 surveys have taken place with 12 occurring prior to the onset of injection operations in August 2012. Soil CO 2 flux appears to positively covary with soil temperature. A notably high soil CO 2 flux value (21 µmol/m 2 /sec) was observed from the D-9-9 #2 chamber location during sampling event #24 (9/24/2014). As a result of this finding, the frequency of soil CO 2 flux monitoring events will be increased to twice-monthly until this anomaly can be confirmed or determined to be an outlier. Soil CO 2 flux monitoring will continue for the duration of the project.

SECARB Initial Injection Period Reservoir Modeling Report

The Southeast Carbon Sequestration Partnership Phase III Anthropogenic Test at Citronelle Field is the United States’ largest CO 2 capture and transportation, injection, storage and monitoring project using CO 2 derived from a coal-fired power station. The project represents a U.S. Department of Energy research and development initiative designed to demonstrate deep underground injection and containment of 100,000 tonnes or more of anthropogenic-source CO 2 . A series of reservoir modeling runs will be performed during the pre-injection, injection, and post-injection phases of the project and will be used to predict plume migration and areal extent. Pressure, temperature, and downhole measurements (seismic, fluid and logging), all data collected as a part of the monitoring program, are utilized as reservoir performance parameters to tune the existing geophysical and geochemical simulation models. The ability to represent site injection activities with the produced detailed simulation models lend credence to long-term forecasts of CO 2 fate and the progress of the CO 2 plume. This report provides an assessment of the simulation model results for CO 2 injection at the Citronelle Anthropogenic Test site from the period of August 20, 2012 to August 31, 2013.

Southeast Carbon Sequestration Partnership (SECARB) Phase III Anthropogenic Test at Citronelle Field, Mobile Co., AL: Project Assessment Report

The Southeast Carbon Sequestration Partnership Phase III Anthropogenic Test at Citronelle Field is the United States’ largest CO 2 capture and transportation, injection, storage and monitoring project using CO 2 derived from a coal-fired power station. The project represents a U.S. Department of Energy research and development initiative designed to demonstrate deep underground injection and containment of 100,000 tonnes or more of anthropogenic-source CO 2 . This report provides an assessment of the CO 2 injection at the Citronelle Anthropogenic Test site for the period August 23, 2012 to August 31, 2013. The purpose of the project assessment is to re-evaluate the AoR for the injection well. The AoR is defined as the region surrounding the geological sequestration project that may be impacted by the injection activity. The AoR is further defined as the farthest reach of the tangible CO 2 plume and/or the region of ‘significant’ reservoir pressure increase. An updated geologic model of the injection zones and storage reservoir sandstones incorporates geologic data obtained from the injection well and characterization wells drilled at the Phase III Anthropogenic Test site. The numerical modeling of the injection was conducted using the updated geologic model, plus the monitoring results obtained to August 31, 2013. The simulation demonstrates effective containment of CO 2 by the reservoir architecture of the upper Paluxy Formation, consisting of multiple, stacked, highly porous and permeable sandstones, separated by low permeability flow barriers. The CO 2 containment demonstrated in this report requires an AoR with a radius of 440 ft from the injection well. This revision reduces the radius of the AoR from the preinjection determination of 1,700 ft. With the revised AoR, the only well within the AoR is the injection well itself, the D 9-7 #2. The nearest well to the injector is the D 9-8 #2. The surface location is 870 ft away from the D 9-7 #2, placing the D 9-8 #2 outside the revised AoR.

Final Report on Reservoir Modeling (SECARB Phase III Work Product 4.2.4.c)

The SECARB Partnership Anthropogenic Test, located in the Southeast Unit of the Citronelle oilfield will inject CO 2 into the saline waters of the Cretaceous Paluxy sandstone formation for three years. In order to accurately model the injection, migration, and long-term fate of CO 2 in the subsurface, GEM, a Computer Modeling Group software program for transport and geochemical modeling, was selected for the simulation. GEM is a very robust compositional reservoir simulator, with all the necessary options available for modeling CO 2 trapping mechanisms (including solubility, residual gas and mineralization). This simulation tool is widely known and used in the petroleum and sequestration industries. A reservoir model was built, based on a previously developed comprehensive picture of the subsurface geology at the site (Work Product 4.2.1.d - Report on Subsurface Characterization for the Anthropogenic Test Project Site). This report describes in details the different inputs that were used to create the model as well as the results of the injection scenario in terms of achievable injection rates, plume extent and pressure response.

Transportation Design and Products Specification (SECARB Phase III Work Product 6.2.2.a)

The SECARB Anthropogenic Test at the Citronelle oil field in Mobile County, Alabama is the largest fully integrated coal-fired carbon capture, transportation and storage project in the United States. Constructed and funded by Southern Company and Mitsubishi Heavy Industries, the CO 2 capture facility at Alabama Power’s 2,657-megawatt Plant Barry captures up to 500 metric tons of CO 2 per day, the equivalent emissions from 25 MW of the plant’s power generation. Captured CO 2 is transported to the mature Citronelle oil field atop a 16,380 acre (66.3 km2 of surface area), geologic salt dome. Citronelle oil field is operated by Denbury Onshore, LLC. The CO 2 is injected through ten perforated intervals in the injection well casing at depths ranging from 9,436 ft to 9,800 ft into the porous and permeable sandstones of the Paluxy Formation. This report describes the transportation design and product specifications for captured CO 2 transported from the capture facility to the underground storage reservoir. CO 2 is transported through approximately 12 miles of pipeline from Plant Barry’s capture facility and is injected into the saline aquifer sandstones of the Paluxy formation at Citronelle oil field. The following outlines the details and characteristics of each point of transportation and the quality of CO 2 being transported.

SECARB Permits for Seismic and Other Site Preparation Plan

The Southeast Regional Carbon Sequestration Partnership’s (SECARB’s) Anthropogenic Test is a demonstration of the deployment of CO 2 capture, transport, geologic storage and monitoring technologies. This project is one of the first and the largest fully integrated commercial prototype coal-fired carbon capture and storage projects in the USA. Drilled in January 2011, a deep characterization well provided geologic data confirming that the test site represented an attractive location for safe, long-term storage of CO 2 . Two Class V Experimental Injection Well underground injection control (UIC) permits were issued in November 2011 and subsequently the project’s injection wells were installed. A robust monitoring, verification and accounting (MVA) plan has been developed to monitor and track the CO 2 plume and the associated pressure field. The CO 2 MVA effort for the Anthropogenic Test CO 2 (Test) injection demonstration includes two wellbore seismic methods, specifically time-lapse Croswell seismic and vertical seismic profiles (VSP). Due to the unique challenges presented by this Test (injection depth of 9,500+ ft. into thin, stacked reservoir sands and limited injection volumes) surface seismic was eliminated as a Monitoring, Verification, and Accounting (MVA) tool. However, the newly drilled project wells provided ample casing diameters (prior to running tubing) to accommodate wellbore seismic receivers (wireline and tubing deployed) and a Croswell source.

The amount of CO 2 captured using this process is equivalent to the emissions produced when generating 25 megawatts (MW) of electricity. CO 2 captured at the plant is transported by pipeline for underground storage in a saline geologic formation within the Citronelle Dome. This project is one of the first and the largest fully-integrated commercial prototype coal-fired carbon capture and storage projects in the USA. This demonstration is currently in the injection phase, with the capture unit reaching full operational capacity in June of 2011. The project constructed a twelve mile long, 4-inch diameter pipeline to the injection site starting in July 2011. Drilled in January 2011, a deep characterization well provided geologic data confirming that the test site represented an attractive location for safe, long-term storage of CO 2 . Two Class V Experimental Injection Well underground injection control (UIC) permits were issued in November 2011 and subsequently the project’s injection wells were installed. A robust monitoring, verification and accounting (MVA) plan has been developed to monitor and track the CO 2 plume and the associated pressure field. In association with this field demonstration, the project team is also tasked with the continued characterization of this region’s potential storage reservoirs and cap rock formations. This document serves as the SECARB Phase III work product 1.1.a “Methodology Paper for Upper Cretaceous Sandstone Characterization.” This product will summarize the Project Team’s plans for the Phase III assessment of the Upper Cretaceous Sandstone Reservoir’s CO 2 storage capacity.

Capacity Report on Knox Group (SECARB Phase III Work Product 1.6.b)

This report assesses the carbon dioxide (CO 2 ) storage capacity for the Knox Group and the Stones River Group in the Mississippi Black Warrior Basin. The results of this evaluation are complimentary to the Geologic Survey of Alabama (GSA) evaluation of potential CO 2 storage reservoirs in the Alabama Black Warrior Basin. The Stones River Group directly overlies the Knox Group and it contains documented porous zones that may be promising for CO 2 sequestration. The Cambrian-Ordovician interval is a thick sequence of carbonates that occurs in multiple geologic settings in the Southeast Regional Carbon Sequestration Partnership (SECARB). The Knox and Stones River Groups could likely only serve as a CO 2 storage reservoir in the southern region of its occurrence, within the Black Warrior Basin. Recorded high porosity zones in the Stones River Group, are likely discontinuous and inconsistent horizons; making it difficult to determine the potential CO 2 storage capacity. Increased data coverage of the Knox and Stones River Groups and a detailed study on injectable zones in these formations would provide a clearer picture on their potential for CO 2 storage.
