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. Petroleum System Assessments 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

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 Federal Land Resource Area High Moderate

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 Drill Pad (X acres) Producer Injector Processing Facility Pipeline
