Transcription

1 The Wyoming Enhanced Oil Recovery Institute (EORI) Lon Whitman Presented at the 13 th Annual CO 2 Flooding Conference December 6-7, 2007 Midland, Texas

2 The EORI Mandate To conduct research to develop new EOR technologies and to promote EOR through the transfer of new and existing technologies in the state of Wyoming. To actively seek the involvement of Wyoming owners/operators, to respond to their needs, and meet their requirements through application of cutting edge science and technical know-how.

7 Enhanced Oil Recovery In Wyoming 51.5 Million Barrels of oil produced in % by EOR 8.5% by CO 2 EOR

8 EOR In Wyoming (cont.) According to WGS ~8 billion barrels of oil remain in the ground 5-15% recoverable by EOR. Only 5% recovery could mean $4 billion to the state of Wyoming over a period of 20 years at $70/bbl.

9 EOR In Wyoming (cont.) Challenges Infrastructure: CO 2 supply and transportation. EORI is investigating new sources within the state. Working with other state agencies (Wyoming Pipeline Authority) and mid-stream companies to overcome infrastructure issues. Lack of pilot data. Production price differential (related to infrastructure).

15 EORI Strategy A mix of research and applied science shaped by the input and direction of Wyoming owners/operators, and in response to the needs of those owners/operators. Based around three areas of activity: Information Assembly Technical Development Technology Transfer

16 EORI Outreach Strategy Information Assembly and Acquisition Fracture Characterization Reservoir Characterization Oil Properties Wettability Three Phase Permeability Rocks and Oil Technical Development Carbon Capture and Storage Scoping Tool Chemical Flooding Water Flooding CO 2 Management Reservoir Modeling Screening Database Development Corporate Outreach and Strategic Alliances Cooperative Associations Contractual Projects Strategic Planning Information Transfer -Meetings - Conferences - Workshops Presentations Publications Incremental Oil Production with EOR Increased State Revenue

17 EORI Outreach Activities In 2007 Joint Producers Meeting, Casper WY, June in attendance. Sponsored by: Chemical Flooding EOR by Dr. Gary Pope, UT Austin, Casper WY, October 26. Single Well Chemical Tracer Testing by Charlie Carlisle, Casper WY, October 26. Nuts and Bolts of CO 2 EOR by Steve Melzer, Casper WY, October in attendance Sponsored by: Future - CO 2 injection - CCS and EOR - Ongoing efforts related to CO 2 infrastructure and supply.

18 EORI Capabilities Technologies and analytical techniques that the EORI is working on directly, promoting or investigating in collaboration with others Technologies Carbon Capture and Sequestration CO 2 Enhanced Oil Recovery Low-salinity water-flooding EOR Chemical Enhanced Oil Recovery Well Stimulation Heat to Power Analyses Screening Models Scoping Models Reservoir Characterization Reservoir Modeling and Simulation

19 Assessing a CO 2 Flood A process of Risk Reduction via a stepwise decision making procedure. Screen: CO2Mac, Fuzzy logic based screen Scope: EORI scoping model Reservoir Characterization Reservoir Modeling and Simulation

20 Risk (Potential for reality to be something other than what is expected) (Reduction of predictive uncertainty) Precision

21 Assessing a CO 2 Flood Screening Models CO2Mac provides a first pass assessment of the technical feasibility of a CO 2 flood in a reservoir i.e. sufficient or compatible values for porosity, perm, fracture pressure and MMP Fuzzy logic screening provides semiquantitative assessment of the likelihood of success of a CO 2 flood.

22 Assessing a CO 2 Flood Scoping Model Similar to Kinder Morgan model Uses Dimensionless Curves to evaluate the economic feasibility of a CO 2 flood. Will be linked to a database of Wyoming reservoirs. Will have batch file and search function capability

23 Assessing a CO 2 Flood Reservoir Characterization Seeks to replace reservoir scale averages used in the previous decision making stages with much higher resolution (facies scale) data. Collation of pre-existing and newly obtained data into a static model of the reservoir. Existing databases, outcrop studies, seismic, wireline logs etc etc).

24 Assessing a CO 2 Flood Reservoir Modeling and Simulation Uses the static model obtained from the reservoir characterization stage. Flow simulation (using ECLIPSE and PETREL) is undertaken to determine the optimal flooding procedure.

25 Example Project (Contractual Study) Elk Petroleum The EORI conducted an evaluation simulation of a gravity stable CO 2 flood of the Grieve Field - Muddy Formation. A detailed reservoir model was constructed and 20 flood simulations were run using the EORI cluster computing facility. The model and simulation was history matched and validated externally (e.g. residual oil saturation measured and compared with the simulation derived value). The results were confirmed by external consultants (Ryder Scott). The study indicated that 23 million barrels was recoverable with production rates of ,000 BOPD.
