The proposed carbon dioxide (CO2) storage site is in northwestern Osage County, Oklahoma. The site is approximately 21 miles northeast of Ponca City, Oklahoma. The small community of Shidler, Oklahoma is located 5 miles southeast of the proposed sequestration site. This site is located approximately 455 feet beneath the North Burbank Unit (NBU), an ongoing tertiary flood in a Lower Pennsylvanian age sandstone reservoir (Burbank), and thus will be called the NBU CCS site.

The sequestration project will consist of 2 injection wells, 1 above zone monitoring well, 1 in-zone monitoring well, and 2 shallow groundwater monitoring wells that are completed above the uppermost confining interval. It is anticipated this site will last for 20 to 25 years and will cumulatively sequester between 11 and 14 million metric tonnes over the life of the project. Storage capacity for this site is estimated to be approximately 100 million metric tonnes of CO2.
