Presentation for the Wyoming Pipeline Authority October 2006
Vicki StampCO2 Program Manager
Rocky Mtn Oilfield Testing Center
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…”
Today’s presentation
• Overview of projects and current status • Focus areas in CO2 EOR and
geologic storage research & technology development• Priorities:
– benefits to industry/ partners – technology transfer / data sharing– contributions to domestic energy development—– Focus on Wyoming EOR
• Estimate possible future CO2 needs: – Budget-dependent

CO2 Science Goals• NEEDS:
– relationship / synergy with EOR– site selection criteria, best practices– demonstration of storage safety and permanence
• Understand key features, effects, & processes– public safety, understanding and acceptance:
• needed for wider deployment of geologic storage– large-scale field tests to inform policy and regulations
• TEAPOT FOCUS:– EOR / storage relationship– site characterization and baseline assessment– leakage risk evaluation, prediction, and management
• behavior of fractures, faults • development of risk mitigation techniques and warning
systems– sensitivity and detection limits of monitoring tools,
recommended suites and practices– wellbore and cement integrity– formal integration and comparison of MMV outputs

Anadarko / Salt Creek CO2 Pipeline
• Location of the pipeline• Proximity to NPR-3
Teapot Dome (NPR-3)
Distance from main line to central NPR-3 location ~15 mi or less.
Site characterization
• Regional geology• Reservoir geology• Reservoir histories
and screening• Soils, aquifers,
reservoir fluids• Petrology, petrophysics, geomechanics, seismic interp. (CSM, UW, TA&M, UH,
BYU, Stanford)
• CO2-specific baseline assessments
Teapot DomeKey components:
NPR-3 Reservoir Summary
9 Producing (oil-bearing) intervals
• Depths 500’-5500’ (Shannon to Tensleep)• Good range of oil/rock chemistry and petrophysics
Additional 5-6 water-bearing intervals
• Fresh and saline, 3000-8000’• Range of dep. environments, clastic (Ss) & carbonate• Crow Mtn. disposal zone• Madison underlies
Tensleep Reservoir • Screening for first target• Tensleep selected
– Well control / few penetrations, modern
– Small, viable EOR target – P = 2350 psi, 32 API– CO2-miscible conditions– Depth 5500’, 8-12% avg
porosity, 80 md, h = 50’– Risk assessment, caprock – Regional benefits– Research, MMV relevance
Proposed Section 10
project area:
S1 fault
Proposed Tensleep EOR / storagedemonstration
• 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
Compelling state and regional drivers to study EOR and storage in the Tensleep at Teapot Dome:
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 Tensleep Section 10 project area

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
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 industry’s research needs and timetable– increase program flexibility and scope– support for additional projects– bring business to Wyoming– could affect CO2 needs
ConclusionsCharacterization 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 >10 MCF/D (600 tons per day)
in multiple deep zones from industrial sources
• Need for secure, long-term CO2 supply
