Duncan Oklahoma is home to Halliburton Company's original headquarters — the oilfield services giant that is one of the world's largest oil and gas companies. Stephens County sits in Oklahoma's oil producing heartland and Duncan serves as a hub for oilfield services in the Anadarko Basin. Oklahoma tornado risk is significant and Duncan sits in a primary tornado corridor. The oilfield services industry concentration creates petroleum infrastructure considerations.
