Denbury Resources Inc. (NYSE: DNR)

Denbury Resources has long since capped its oil and gas operations in its native Canada to try its luck in the Deep South. The independent exploration and production company has estimated proved reserves of nearly 130 million barrels of oil equivalent and working interests in wells across Louisiana, Mississippi, Texas, and in the Gulf of Mexico. In Mississippi it also owns wells that produce carbon dioxide (CO2), which it uses to force oil out of the ground at nearby abandoned wells. In 2002 Denbury Resources bought Genesis Energy LLC, the general partner of Gulf Coast crude oil marketer Genesis Energy, L.P., and the Gulf Coast properties of Coho Energy.
