Oklahoma City-Chaparral Energy’s CO2 subsidiary said March 29 that it has executed a long-term carbon dioxide (CO2) purchase and sale agreement with a subsidiary of CVR Energy for capture of CO2 from CVR’s Coffeyville, Kans., nitrogen fertilizer plant. The agreement provides for the purchase of CO2 for Chaparral’s initiation of enhanced oil recovery operations in its North Burbank Unit in northeastern Oklahoma. CVR’s nitrogen plant currently produces 850,000 st/y (40 MMscf/d) of CO2. In this new project, almost all of the fertilizer plant’s CO2 will be captured by Chaparral, who will construct a CO2 compression facility at the plant site and install approximately 70 miles of pipeline to deliver the CO2 to its North Burbank Unit in Osage County. Injection is expected to commence no later than July, 2013.
