Comments: EOR started in these fields as early as 1982. However CO2 from Enid Fertilizer has been used since 2003.

In early 2010, Koch Nitrogen completed upgrades and expansion of its Enid Oklahoma Plant, having purchased the plant in 2003.

Chaparral Energy is also operating the Coffeyville CO2 capture project in Kansas, where in 2013 0.85 MT/yr CO2 is captured for EOR.

In 2005 Anadarko Petroleum had 2 CO2 floods ongoing at the Northeast Purdy and Bradley Unit fields. The EOR production from the Northeast Purdy Field was 1,800 bbls/day, and in the Bradley Unit 600 bbls/day.
