“Perspectives on Montana’s Petroleum Industry” MREA-MPA-MONTAX “Bridges to the Future” Conference October 15, 2009 Dave Ballard President Ballard Petroleum Holdings LLC Billings, Montana

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 CO 2 Flood Enhanced Oil Recovery Sensitive Environment Operations

Subsurface Prospect Mapping Examples Fred & George Creek (1963) Bell Creek (1967) Elm Coulee (2000) Cutbank (1926) Sumatra (1952)

Stratigraphically Trapped Oil Example Fred & George Creek Oil Field, Toole County, MT Sunburst –A Channel Map and Cross Section Discovered 1963 using subsurface geology From: Montana Geological Society, 2006, “Montana Oil & Gas Fields”

Bell Creek Oil Field, Powder River County, Montana Muddy Sand Isopach Map Discovered 1967 using subsurface geology Cum 132 MMBO

Bell Creek Oil Field, Powder River County, Montana 17 dry holes drilled in the area prior to discovery
