### The injection well was plugged back from the bottom with at least 80 feet of cement or a greater amount sufficient to prevent the injection fluid from coming in contact with the Precambrian

g ranite basement. The figure below is a well construction schematic for CCS#1.Construction Details for ADM CCS#1 Page G3of 5

### Pre-Injection Testing

Deviation Checks The subsurface and surface design (casing, cement, and wellhead designs) exceeds minimum requirements to sustain the integrity of the caprock to ensure that the CO 2 

### remains in the Mt. Simon. The final well design met strength and CO 2 

### compatibility requirements.

The wellbore trajectory of each of the deep wells for the Illinois Basin-Decatur Project (injection, verification, and geophysical wells) was tracked. The wells were drilled to an

inclination st andard that eliminated the risk of interception with adjacent wellbores and surveyed

a t least every 1,000 feet of depth to ensure compliance. Wells were held to less than 5 degree

inclination.

T ests and Logs The following testing and logging was performed.

Duri ng Drilling Each open hole section (prior to setting each casing string) w as logged with multiple suites to fully characterize the geologic formations (reservoirs and seals). Wireline resistivity, elemental capture spectroscopy, spontaneous potential (SP), gamma ray (GR), photoelectric factor and bulk density, and caliper logs were run. Sonic and compensated neutron porosity logs were also

include d on the intermediate and TD run. The TD run also included magnetic resonance, microimaging (dipmeter and fracture ID), formation pressure and rotary cores.

F or the injection well, 90 feet of whole core were obtained for the Eau Claire and the Mt. Simon.

12 si dewall cores were taken in the Eau Claire formation and 1 sidewall core was taken in the granite formation below the Mt. Simon.

A Cement Bond Log (CBL) with radial capability and/or Ultrasonic Cement Imaging logs was run on all casings strings with a possible exception for the surface casing. Due to the large surface casing size, a cement bond log with radial imaging was not possible; however, a

c onventional CBL and temperature log was run. The cement bond logs showed some isolated

a reas with channels or microannuli; however, they did not appear to be continuous or to

c ompromise zonal isolation. The successful circulation of cement to the surface indicates an

int act cement sheath.

During and After Casing Installation A baseline reservoir saturation tool (RST) and temperature log were run; these will be compared

with m ultiple passes during and after injection for detailed knowledge of where the CO 2 

### has moved vertically. Careful monitoring of the top of the Mt. Simon Sandstone formation, as well as the porous zones above the seal, was used to confirm the integrity of the completion.

Ultra sonic Cement Imaging logs with radial capability were run on the intermediate and long string casings. Ultrasonic Imaging logs provided casing thickness and internal radius baseline measurements in addition to cement evaluation data. Casing internal diameters were baselined by running a multi-finger caliper (MFC) log in the long string casing prior to the well completion.Construction Details for ADM CCS#1 Page G5of 5

### Based on previous analysis and results in the area, stimulation via hydraulic fracturing of the injection zone was not required. The perforations were acidized using 15 percent hydrochloric

a cid to reduce formation damage caused by drilling. A dynamic underbalanced perforating technique was u sed.

After the well was cased, three pressure fall-off tests were performed to provide data for the

re servoir modeling. Since injectivity testing is best analyzed in a single-phase fluid environment, the ga uges were placed near a perforated interval, and then fluid was inject ed for a period and the pressure fall-off was measured. A total of three pressure fall-off tests were conducted. The first involved injection for 2 hours and monitoring for 19.5 hours; the second involved injection for 5

hours a nd monitoring for 45 hours; the last test involved injection for 13 hours and monitoring

for 105 hours. Also at this time, a step rate test was performed to determine the fracture gradient.

The well was perforated between 6,976 - 6,978

, 6 ,982 -7 ,012, and 7,025.5 – 7,050.5 feet.

Demonstration of Mechanical Integrity

Cement and system mechanical integrity were verified after construction with cement imaging log s with a radial capability (UltraSonic Imaging Tool, USIT). Furthermore, mechanical integrity

was confirmed by pressure testing the casing (750 psig) prior to perforating, and after the packer

wa s installed, the tubing/casing annulus was pressure tested. All tests were recorded. The

pre ssure drop during the pressure test was 5 psi over an hour, resulting in a passed test. As

mentioned a

bove, a baseline reservoir saturation tool (RST) log was run. Repeat RST logs can be

run if anomalous temperature data indicates a need for further analysis. Careful monitoring with temperature data across the top of the Mt. Simon Sandstone formation, as well as the porous zones above the seal, were used (along with data from the verification well) to confirm the integrity of the completion.
