Our history

A long and proud past of finding and producing oil and gas.

ConocoPhillips began publicly trading as an independent exploration and production company in 2012, building on a legacy that dates back 150 years to some of the earliest discoveries of oil and gas in the United States. That lineage includes energy pioneers such as Conoco, Phillips, Concho, Marathon Oil, Burlington Resources, DuPont, Marland Oil, Continental Oil and Standard Oil.

Our history illustrates a relentless focus on safety, a passion for innovation and an ability to adapt to a dynamic marketplace. We are proud of our commitment to improving life for people and communities.​​​
