1. Resource Assessment of Oil & Gas, Coal-Bed Methane, and Geothermal Resources in Western Washington Department of Geology Portland State University M. Cummings, J. Jackson, D. Percy

2. Objectives • Phase One: Review literature to identify play concepts and data for subsequent evaluation • Phase Two: Evaluate and tabulate data for use in subsequent evaluation

3. Phase One Activities • Compile and review existing literature relating to oil and gas resources • Compile and review existing literature relating to coal-bed methane resources • Compile and review existing literature relating to geothermal resources • GIS review of existing physical and digital maps

4. Phase One Products • Annotated Bibliography • Database of existing digital and map resources

5. Phase Two Activities • Enter oil & gas related data into digital database • Enter coal-bed methane related data into digital database • Enter geothermal related data into digital database

6. Phase Two Products • Database of oil & gas, coal-bed methane, and geothermal energy resources, with evaluation of utility for subsequent analysis. • Preliminary map showing areas of high, medium, and low resource potential for oil & gas, coal-bed methane, and geothermal energy resources.

7. Phase Three: Resource Assessment • Petroleum Systems Assessment • Coal-Bed Methane Systems Assessment • Geothermal Systems Assessment • Federal Land Assessment • Preliminary Surface Impact Estimate

8. Petroleum Systems • Source Rock • Maturation • Migration • Structure • Reservoir • Seal

10. Mass-Balance Source Richness Source Volume Hydrocarbon Generation Hydrocarbon Migration Trapping Efficiency Hydrocarbon Recovery Play Summation Minimum Field Size Maximum Field Size Minimum Number Maximum Number Monte Carlo Sum Petroleum System Assessments

11. Coal-Bed Methane System

12. Coal-Bed Methane Assessment • Gas Research Institute Mass-Balance • Coal area (a) • Coal thickness (h) • Average rock density (d) • Average gas content (g) • Gas-in-place = (1359.7) a h d g

13. Geothermal Systems • Volcanic Center • Heat • Permeability • Water

14. Geothermal Assessment • Identify appropriate volcanic terrain analogs • Identify producing geothermal facilities from analog terrain. • Adjust assessment to account for differences between assessed terrain and analog terrain.

15. Federal Land Assessments • Oil & Gas play area on Federal land • Coal-Bed Methane play area on Federal land • Geothermal terrain on Federal land • Potential Gas Storage Centers on Federal Land Mod Resource Area High Moderate Federal Land

16. Preliminary Impact Estimates • Oil & Gas • Surface foot print • Water resource impact • Coal-Bed Methane • Surface foot print • Water production • Geothermal facility • Surface foot print • Water production Producer Processing Facility Injector Pipeline Drill Pad (X acres)

17. Phase Three Products • Oil & Gas Play Summary Maps • Resource Assessments For Each Play • Coal-Bed Methane Potential Maps • Coal-Bed Methane Resource Assessments • Geothermal Resource Maps • Geothermal Resource Assessments • Federal Land Assessments • Preliminary Surface Impact Estimates • Technical work recommendations
