CLASS VI OPERATING AND REPORTING CONDITIONS 

Facility Name: FutureGen 2.0 Morgan County CO2 Storage Site 

IL-137-6A-0004 (Well #4) 

Facility Contacts: Kenneth Humphreys, Chief Executive Officer, 

FutureGen Industrial Alliance, Inc., Morgan County Office, 

73 Central Park Plaza East, Jacksonville, IL 62650, 217-243-8215 

Location of Injection Well: Morgan County, IL; 26−16N−9W; 39.80111oN and 90.07544oW 

Injection Well Operating Conditions: 

PARAMETER/CONDITION LIMITATION or PERMITTED 

VALUE

UNIT

Maximum Injection Pressure

Surface 1,171 psig

Downhole 2,237 psig

Annulus Pressure 100 minimum psig

Annulus Pressure/Tubing Differential 100 above surface injection pressure psig

The downhole gauge for injection pressure monitoring is located at: 3,850 feet below ground surface. 

The maximum injection pressure, which serves to prevent confining-formation fracturing, was determined 

using the following formula/methodology: 

 For maximum injection pressure using a downhole pressure gauge, the maximum pressure is 

calculated as follows: 90% of fracture pressure of the injection zone. Therefore, the maximum 

injection pressure using downhole pressure gauge is 2,252 psia or 2,252-14.7 = 2,237 psig. 

 For surface maximum wellhead injection pressure, this limitation was calculated using the 

following formula: [{90% of fracture gradient-(0.433psi/ft)(specific gravity)} X upper depth of 

perforated interval ] - atmospheric pressure. The maximum wellhead injection pressure is: 

[{0.585-(0.433)(0.64 )}3850] -14.7 = 1,171psig. 

If the downhole pressure gauge fails to function properly, then the maximum injection pressure shall 

immediately be limited to the calculated surface pressure until the downhole pressure gauge is repaired or 

replaced. 

Shutdown Procedure: 

The permittee has not developed procedures for implementing a gradual well shutdown.

Therefore, unless and until other procedures are developed and approved, every situation that 

warrants shutting down the well (from routine maintenance to emergency conditions) will 

require an immediate shutdown.
