Westward Expansion of the<br />

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

Elements for Success in American’s Goliath Area<br />

GR<br />

Res<br />

• Regional studies<br />

and hydrocarbon<br />

shows strongly<br />

supported prospect<br />

Wellbore<br />

trace<br />

• Strictly maintain<br />

bit in target<br />

• Stimulation: multi-stage<br />

(25-35), moderate pump<br />

rate, high-strength<br />

proppant stimulation<br />

• Carefully designed<br />

flowback plan
