Presentation Overview

• Industry Overview and Economic Contribution• Meet the Producers• Producing Areas and Trends• Geologic Elements of an Oil Field• Regional Geology

• Field Examples and the Technology of Discovery and Production

• Have We Reached Peak Production?

Field Examples and the Technology of Discovery and Production

• Surface Geologic Mapping• Subsurface Geologic Mapping• Seismic Mapping• Shallow “Tight” Gas Frac Stimulation• Horizontal Drilling and Frac Stimulation• Waterflood Enhanced Oil Recovery• CO2 Flood Enhanced Oil Recovery• Sensitive Environment Operations
