Challenges and Barriers

• GHG Reduction “Solutions”– Carbon Capture & Storage– High Efficiency Electric Vehicles– Nuclear Power– 2nd Generation Biofuels

• Are 10 years away– Climate scientists tell us GHG emissions need to

peak in 10-15 years, then begin dramatic decline.

The Role of CO2-EOR in Reducing GHG Emissions

• Revenues from sale of captured CO2 can Jump-start the application of CCS technology

• Oil produced from CO2-EOR has lower carbon impact than traditionally produced oil.

provides an “early action pathway” for overcoming the initial barriers:• Regulatory / Public Acceptance• Long-term Liability • Pore space Ownership to Geological Storage of CO2

It can also provide significant revenues. For example, a one GWsize coal-fired power plant emitting 6 MMmt of CO2 a year and selling this CO2 (at pressure and at the plant gate) for $35 per mt would realize $6.3 billion in 30 years.

Storing COStoring CO22 with Enhanced Oil Recoverywith Enhanced Oil Recovery

Advanced Resources recently completed a report for DOE/NETL entitled “Storing CO2 with Enhanced Oil Recovery,”* an update to the previously published “basin studies”.**

• Examines economically recoverable oil from applying CO2-EOR (oil price $70/B; CO2 cost $45/mt),

• Addresses market demand for CO2 by the EOR industry• Uses a streamline reservoir simulator and a data base of

2,012 large oil reservoirs (74% of U.S. oil production),• Covers 27 producing states plus offshore Louisiana.

*Available on the U.S. DOE web site. http://www.netl.doe.gov/energy-analyses/pubs/Storing%20CO2%20w%20EOR_FINAL.pdf**Available on the U.S. DOE web site. http://www.fe.doe.gov/programs/oilgas/eor/Ten_Basin-Oriented_CO2-EOR_Assessments.html

Summary RemarksSummary Remarks

• CO2-EOR offers a large, “value added” market for captured CO2 emissions of 7,500 million metric tons (equal to 49 GWs of advanced coal-fired power).

• Storing CO2 with EOR helps bypass three of today’s barriers to geological storage of CO2 - -regulatory/public acceptance, mineral (pore space) rights and long-term liability;

• The oil produced with CO2–EOR is 70% “carbon-free”. It can become 100+% “carbon-free” with “next generation” technology.

Economics and Cost Model• Costs Accounted For:

– Drilling new wells or reworking existing wells– Surface equipment for new wells– CO2 recycle plant and CO2 spurline from main trunkline to the oil

field

– Operation and Maintenance (O&M)• Lifting produced fluids• Capturing, Separating, and Reinjecting CO2

• Economics:– Economic model uses an industry standard cash flow that can be

run on a pattern or a field-wide level and it accounts for:• Royalties• Severance and Ad Valorem Taxes• Oil Gravity and Market Location Differentials• Oil Prices, CO2 Costs, and Other Variables

Advanced Resources InternationalMay 6, 2008

CO2 Injection and Storage Process• Initially, purchased CO2, equal to 1 HCPV is injected with water for mobility control.

• As oil is produced, CO2 is separated from the oil and reinjected. As produced volumes of CO2 increase, these larger volumes are reinjected.

• At the end of the project, operator can close the field at pressure, storing essentially all of the injected CO2, or inject a large (1 to 2 HCPV) slug of water to recover any remaining oil and CO2. This CO2 may be used again.
