Duncan once adopted the slogan, "The Buckle on the Oil Belt". Its main claim to fame is as the birthplace of the Halliburton Corporation.<ref name="ohsduncan" /> [[Erle P. Halliburton]] perfected a new method of cementing wells, making oil production much easier and more profitable, and established the New Method Oil Well Cementing Company in 1919. He died in 1957, when the company had 201 offices in 22 states and 20 foreign countries. Halliburton maintains seven different complexes in Duncan, but the corporate offices relocated first to Dallas and later to Houston.

Halliburton operates the Halliburton Technology Center in Duncan. In 2010, Halliburton announced that 150 jobs in the center were to move to Houston over the following two years.<ref name="tulsaworld">"[http://www.tulsaworld.com/news/article.aspx?subjectid=11&articleid=20100218_11_0_DUNCAN251071 Halliburton to move jobs from Duncan to Houston] {{Webarchive|url=https://web.archive.org/web/20121012070146/http://www.tulsaworld.com/news/article.aspx?subjectid=11&articleid=20100218_11_0_DUNCAN251071 |date=October 12, 2012 }}."
