The Teapot Dome Field Experimental Facility
CO2 Program Summary

• Presentation for the Wyoming Pipeline Authority
• October 2006
• Vicki Stamp
• CO2 Program Manager
• Rocky Mtn Oilfield Testing Center

2
May 12, 2006 U. S. Senate, Committee on Energy
and Natural Resources

• The Energy Policy Act of 2005 required the
  Department of Energy to develop new technologies
  for Enhanced Oil Recovery (EOR) though injection
  of carbon dioxide into marginal oil wells.  The
  Act also required the Department to study the
  potential for increasing oil recovery using
  carbon injection technologies

Proposed Tensleep EOR / storagedemonstration
Compelling state and regional drivers to study
EOR and storage in the Tensleep at Teapot Dome

• 2/3 of Wyoming production comes from Tensleep
  or equivalent
• Rangely CO2 EOR in the Weber (Tensleep
  equiv.)
• Significant volumes in Colorado
  Utah
• Analogs throughout U.S.
  internationally

Tensleep fm, Alcova Canyon, WY

NPR-3 Gravity-Stable Miscible CO2

• Cost-effective testing of gravity-stable
  operation in Tensleep fm
• High relief structure
• Significant fracturing, faulting
• Active aquifer
• Available wellbores for both operation and
  monitoring
• Fluid analyzed and test design simulated
• Lab fluid tests were used to generate equation of
  state inputs for reservoir simulation tuning
• Simulation completed at field scale and proposed
  test scale

Proposed Section 10 EOR / Storage Project Key
Points

• Modest EOR target
• Small capital outlay required
• Seamless transition to storage-optimized
• Template with broad applicability
• Public domain results
• Expansion / long-term operation possible if
  successful
• Other zones possible
• Ex 2nd Wall Creek

Saline Aquifer CO2 Storage Test

• Crow Mountain Ss (4500)
• 3 existing Class II disposal wells, Section 10
• Co-locate with Tensleep EOR project
• Water analysis, permeability, caprock
• Several surrounding wells available for
  monitoring
• Focus
• MMV tool sensitivity and detection limits,
  comparison, integration of results
• Predict and quantify multiple storage mechanisms

18
Joint Industry Project (JIP)

• Industry suggestion
• Under development
• Notice posted on LLNL website
• Finalizing package for potential partners
• Funding independent of DOE and Federal budgets
• Industry-driven
• to better meet industrys research needs and
  timetable
• increase program flexibility and scope
• support for additional projects
• bring business to Wyoming
• could affect CO2 needs

19
Conclusions

• Characterization results have showcased the
  strengths of Teapot Dome as a project site for
  focused research on CO2 EOR, monitoring and
  storage.
• Earliest projects proposed will focus on
• EOR / oil field storage
• Suite of projects under consideration includes
• EOR project expansion
• Saline aquifer storage
• Tests for monitoring (MMV) tool development,
  sensitivity, comparison and integration
• Long-term testing related to storage safety and
  wellbore integrity

Conclusions

• Can grow / stimulate CO2 EOR and CO2 storage
  research in Wyoming
• increasing Wy and domestic production
• growing national and global efforts aimed at
  reduction of CO2 emissions
• Domestic and international partners
• benefits to Wyoming business and the public
• Environmentally sound
• Possible to use at least 3-10 MCF/D for EOR
• Could permanently store gt10 MCF/D (600 tons per
  day) in multiple deep zones from industrial
  sources
• Need for secure, long-term CO2 supply
