THE OBJECTIVE OF THE ILLINOIS BASIN WEST CARBONSAFE PHASE III PROJECT IS TO GEOLOGICALLY CHARACTERIZE THE CAMBRIAN MT. SIMON SANDSTONE/EAU CLAIRE FORMATION STORAGE COMPLEX NEAR THE DALLMAN POWER GENERATION PLANT IN SPRINGFIELD, ILLINOIS, AND TO SUBMIT THE REQUIRED UNDERGROUND INJECTION CONTROL (UIC) CLASS VI PERMIT TO CONSTRUCT APPLICATION(S) THAT MAY BE USED FOR CONSTRUCTION OF A CARBON DIOXIDE (CO2) INJECTION WELL(S) AT THE PROJECT SITE. INITIAL PROJECT TASKS WILL FOCUS ON SITE CHARACTERIZATION, ACQUISITION OF SEISMIC PROFILES, DRILLING OF A STRATIGRAPHIC TEST WELL, COMPLETION OF REQUIRED CLASS VI PERMIT TO CONSTRUCT APPLICATION(S), AND IMPLEMENTATION OF THE PROJECT’S COMMUNITY BENEFITS PLAN. FINAL PROJECT TASKS FOCUS ON INTEGRATING ALL CHARACTERIZATION DATA, FINALIZING A SITE-SPECIFIC STORAGE FIELD DEVELOPMENT PLAN, AND CONTINUING IMPLEMENTATION OF THE PROJECT’S COMMUNITY BENEFITS PLAN TO FURTHER CARBON CAPTURE AND STORAGE (CCS) DEPLOYMENT. THIS PROJECT WILL BENEFIT DOE'S PROGRAM BY: (1) REDUCING GEOLOGICAL UNCERTAINTY AT THE SITE BY DRILLING A STRATIGRAPHIC TEST WELL TO APPROXIMATELY 5,800 FT, COLLECTING CORE THROUGH RESERVOIR AND SEAL INTERVALS, COLLECTING A ROBUST SUITE OF GEOPHYSICAL LOGS, AND ACQUIRING APPROXIMATELY 60 LINEAR MILES OF 2D SEISMIC SURVEYS IN THE VICINITY OF THE SITE; (2) USING EXISTING AND NEWLY ACQUIRED DATA TO DEVELOP A GEOLOGICAL CONCEPTUAL MODEL FOR THE AREA THAT WILL BE INCORPORATED INTO STATIC GEOCELLULAR MODELS AND THEN USED FOR DYNAMIC SIMULATION TO ASSESS CO2 INJECTION AND STORAGE PERFORMANCE AND LONG-TERM CONTAINMENT; AND (3) USING VARYING INJECTION AND OPERATIONAL SCENARIOS TO MODEL POTENTIAL METHODS OF IMPROVING RESERVOIR STORAGE EFFICIENCY. THE BENEFICIARIES ON THE PROJECT INCLUDE A VARIETY OF TECHNICAL, RESEARCH ORIENTED AND COMMERCIAL STAKEHOLDERS, AS WELL AS, NEARBY PROPERTY OWNERS AND COMMUNITIES. IN ADDITION, MANY FEDERAL STATE, AND LOCAL REGULATORY AND ENVIRONMENTAL PROTECTION AGENCIES ARE ALSO BENEFICIARIES TO THE PROJECT AS THEY WILL USE RESULTS OF THE DATA COLLECTION AND MODELING TO FURTHER CCS SAFE, PERMEANT COMMERCIAL STORAGE.
