Kansas Geological Survey Open-file Report 2001-38 |
EconomicsCO2 enhanced oil recovery economics are most sensitive to oil price and CO2 costs. It is projected that CO2 can be delivered to central Kansas for $1.00 per MCF provided there is an adequate resource base to provide a market for 200 BCF CO2 over a ten to twenty year period. This figure shows the sensitivity to oil price, holding other costs such as CO2, operations, and capital constant. For a 20% inernal rate of return (IRR) $25/bbl oil price1.4 Net MBO per acre needs to be recovered while at $15/bbl 4.7 net MBO per acre recovery is needed. |

| 1998-99 | Feasibility study conducted by University of Kansas (KGS and TORP), and Shell CO2 Company (now Kinder Morgan CO2 Co. L.P.). Funding support came from Kansas Technology Enterprise Corp., University of Kansas, and Shell CO2. Submitted grant proposal (1999) to DOE. |
| 2000-01 | DOE grant awarded and work begun. Data gathering, reservoir characterization, drill and core CO2 injection well, additional resource assessment reservoir simulation, and technology transfer. |
| 2001 | Well injection testing, further reservoir simulation, drill, core and test second CO2 injection well. Wellbore upgrades and install surface facilities. |
| 2002 | Pre-flood repressuring of reservoir to 1250 psi (presently 600-800 psi), install balance of surface facilities, and begin CO2 injection. |
| 2003-05(?) | CO2 slug and WAG |
| 2005-07 | Post-CO2 waterflood |
