3 Illinois Industrial Carbon Capture and Storage Project DOE-FE ICCS Program Project cost of $208 million (DOE $141.4M) ADM, Decatur, Illinois (Saline storage) [Illinois ICCS project] Two DOE-Sponsored CCS Projects in Decatur, Illinois Illinois ICCS Project (Lead - ADM) Initiating operation in 2017 (one million tonnes per year capacity) Illinois Basin Decatur Project (Lead - ISGS) completed operation in November 2014 (sequestered one million tonnes of CO 2 over three years) Scale up factor of 3 to represent the operating capacity necessary for commercial power generating facilities. 3

4 Key Results of the IBDP Favorable porosity, permeability, and capacity properties of Mt. Simon Sandstone. Deep saline formation and three overlying caprock seals; hence, no adverse impacts were detected to date. Accepted CO 2 more easily than initially expected. Because of reservoir permeability stratification, with approximately one million tonnes injected, CO 2 remained in the lowermost Mt. Simon Sandstone. 4

6 USEPA UIC Class VI Permit USEPA s Underground Injection Control permit to construct and to operate a Class VI injection well for the purpose of geologic sequestration of CO 2 Class VI permit has specific requirements for safe injection and storage of CO 2 Area of Review Maximum extent of the separate-phase plume or pressure-front (MESPOP) Class VI Permit Project Plan 6

7 Illinois ICCS Project Site Monitoring To demonstrate: Underground Sources of Drinking Water are protected CO 2 is safely and permanently stored CCS is safe, effective, and acceptable for GHG control Monitoring activities include: Shallow Groundwater Monitoring Network Deep Fluid Monitoring Well Logging Mechanical Integrity Testing (MIT) Pressure/Temperature Monitoring CO 2 Stream Analysis Time-Lapse Vertical Seismic Profile Survey 7

Downhole gauge located at 6267 ft Schlumberger packer set at 6311 ft (Depths Kelly Bushing 15.5 ft) 10

11 ICCS Project: Verification Well 7140 ft depth Perforated at the following depths: Ironton Galesville formation ft (zone 5); Mount Simon formation: ft (zone 4), ft (zone 3), (zone 2), and ft (zone 1). The pressure and temperature gauges were installed at depths of 5027 ft, 5848 ft, 6524 ft, 6681 ft, 7041 ft (Depths Kelly Bushing 17 ft) 11

12 ICCS Project: Verification Well (cont.) Installed Schlumberger s IntelliZone (IZ) Compact* modular multizonal management system P/T gauges were positioned on the tubing, leaving the interior open for RST* logs and other surveys. Allows for periodic saturation logging using RST* reservoir saturation tool. Fiber-optic Distributed Temperature Sensor (DTS) IZ system operates in conjunction with Schlumberger s WellWatcher *mark of Schlumberger 12

17 Project Status Completed design and construction of the CO 2 compression, dehydration, and transmission facilities. A new 100 MW electrical substation and associated transmission lines were constructed and made operational. A 7192-ft Class VI injection well, a 7240-ft monitoring (verification) well, and a 3550-ft geophysical well were drilled and completed. As of September 2016, this project has completed over 99% of its construction; commissioning is in progress. Collected baseline site monitoring data. EPA permit review for injection authorization is in progress. Anticipate to begin CO 2 injection operations in
