An oil rig in use in Denbury's operations.

Our History

Denbury has been actively involved in carbon management for more than 20 years, and our company history dates back more than 70 years.

Denbury has been active in oil and natural gas production in the U.S. Gulf Coast since the early 1990s, and in 1999 began operating its first CO2 enhanced oil recovery project at Little Creek Field in Mississippi. Over the last 20+ years, Denbury has initiated more CO2 floods than any other company and has constructed and amassed CO2 pipelines spanning more than 1,300 miles in the U.S. Gulf Coast and Rocky Mountain regions, the largest network of CO2 pipelines owned and operated by any single company in the U.S. With Denbury’s expertise in managing CO2 and its large CO2 pipeline infrastructure, Denbury is ideally positioned to be a leader in the rapidly expanding Carbon Capture, Utilization, and Storage (“CCUS”) business. We are proud of our past, and even more excited about what we will accomplish in the future. The timeline below shows key events in Denbury’s history.

The name Denbury derives ultimately from the name of a Devonshire village in England. In April 1990, Gareth Roberts founded Denbury Management, Inc. the original operating subsidiary of Denbury.
