In this video, energy analyst Joel South explains why Denbury Resources (DNR) looks attractive as a long-term investment. Unlike unconventional shale drillers who experience sharp well decline curves, Denbury uses CO2-enhanced oil recovery, which helps increase crude extraction over 10 years before wells hit a long and slow decline curve; this method will increase the company's free cash flow position down the road. In addition to long-term revenue streams, Denbury's tertiary recovery could double the company's proven reserves, making today's valuations look that much better.
