The Cedar Creek Anticline (CCA) is a major geological feature that extends for approximately 125 miles and is about 110 miles north of Denbury’s Bell Creek field. The formation ranges from two to six miles in width. It’s made up of a series of producing oil units, each of which could be considered a field by itself. Commercial quantities of oil were first discovered in the South Pine Unit of CCA in the early 1950s. The original oil in place at all CCA fields, including those not owned by Denbury, is estimated at over 3 billion barrels of oil. The reservoir characteristics of CCA are similar in many respects to oil fields successfully flooded with CO2 in the Permian Basin of West Texas and Weyburn field in the Canadian Williston Basin.
Denbury is currently designing a CO2 and estimates a CO2 flood of its CCA assets could recover between 260 million to 280 million barrels of oil.
