Westward Expansion of the<br />
Bakken <strong>Oil</strong> Resource Play in<br />
North Dakota<br />
• American’s early drilling in 2006 in Goliath<br />
prospect area was disappointing<br />
• Burial History, Regional Trends and<br />
Hydrocarbon Shows indicated otherwise<br />
• Prospect Area considered high risk by other<br />
operators based on Petrophysical Analyses<br />
• Subsequent to technical re-assessment,<br />
American resumed building acreage position to<br />
over 90,000 net acres with minimal competition

supported prospect<br />
Wellbore<br />
trace<br />
• Strictly maintain<br />
bit in target<br />
• Stimulation: multi-stage<br />
(25-35), moderate pump<br />

proppant stimulation<br />
• Carefully designed<br />
flowback plan
