Denbury said the property contains an estimated 20 million barrels of oil equivalent (MMBoe) of proved conventional reserves as of Dec. 1. This translates to a purchase price of about $21.54 per barrel of oil equivalent.
The purchase price would consist of about 11.6 million of Denbury shares and $256.4 million in cash, the company said.
Denbury expects to cover about $210 million of the cash portion with the sale of its remaining Barnett Shale assets to Talon Oil & Gas LLC.
Talon had earlier this year purchased 60 percent of Denbury's Barnett Shale assets.
Production from the Barnett assets being sold averaged about 4,596 barrels of oil equivalent (BOE/d) during the third quarter of 2009, Denbury said.
"Our net production will decrease as a result of the two transactions, but with the higher margins currently earned on oil properties, we expect a slight increase in our net projected cash flow for 2010 if commodity prices remain at current levels." Chief Executive Phil Rykhoek said.
The company also expects to spend an additional $750 million to $1.0 billion to develop Conroe Field as a tertiary flood.
Denbury shares, which have nearly doubled in value from a December 2008 year-low, were almost flat at $13.22 Thursday morning on the New York Stock Exchange.
