                    Denbury Adds 29 MMBOE of Reserves in 2004
                            From Internal Development
News Release
Released at 7:30 AM CDT

     DALLAS - February 1, 2005 - Denbury Resources Inc. (NYSE symbol: DNR) today
announced  that its total proved oil and natural gas reserves as of December 31,
2004 were 129.4 million barrels of oil equivalent  (MMBOE),  consisting of 101.3
million  barrels  (MMBbls)  of crude oil and 168.5  billion  cubic feet (Bcf) of
natural gas. This total  represents a 15% increase over Denbury's proved reserve
quantities  at December  31, 2003 after  adjusting  for the 16.4 MMBOE of proved
reserves sold during 2004.  DeGolyer and MacNaughton,  an independent  reservoir
engineering firm, has prepared Denbury's year-end reserve report for each of the
last four years.

Proved Reserve and Finding Cost Analysis
- ----------------------------------------

     Denbury added 29.6 MMBOE of proved  reserves  during 2004 (before  property
sales and production),  almost entirely from internal organic growth,  replacing
247% of its 2004-estimated  production.  The most significant  reserve addition,
18.7  MMBbls,  is related to the  Company's  tertiary  oil  recovery  project at
Brookhaven Field in Mississippi.  The Company also added approximately 45 Bcf of
reserves from additional natural gas wells in the Barnett Shale near Fort Worth,
Texas.   Preliminary   estimates  of  capital   spending   during  2004  include
approximately  $166  million for  development  and  exploration  activities  and
approximately $11 million expended for  acquisitions.  The Company also spent an
estimated $50 million on its CO2 producing wells and facilities and received net
proceeds  from  property  sales during the year of  approximately  $198 million,
including  net  proceeds  of  approximately  $187  million  from the sale of its
offshore properties. Based on these preliminary expenditure estimates, excluding
the CO2  expenditures,  the 2004 sale of offshore  properties  and 2004 activity
thereon,  and the change in future development cost and retirement  obligations,
Denbury's  finding and  development  costs for 2004 were an estimated  $5.35 per
BOE.   Approximately  55%  of  Denbury's   year-end  2004  proved  reserves  are
categorized as proved developed.

     In accordance with SEC requirements,  Denbury's proved reserves at December
31, 2004 were computed using unescalated year-end 2004 NYMEX commodity prices of
$43.45  per  barrel of oil and $6.15 per MMBtu of natural  gas,  with  necessary
adjustments  applied  to each field to arrive at the net price  received  by the
Company as of December 31, 2004. Using these prices,  the discounted net present
value of Denbury's proved  reserves,  before projected income taxes, at December
31,  2004,  using  a 10%  discount  rate  ("PV-10  Value")  was  $1.64  billion,
approximately  31% higher than the Company's  PV-10 Value a year earlier  (after
adjusting for the PV-10 Value of the offshore proved reserves sold during 2004).
PV-10 Value is different than the standardized  measure of discounted  estimated
future net cash flows, which is an after-tax calculation. Proved reserves at the
prior year-end were computed using  unescalated NYMEX commodity prices of $32.52
per barrel of oil and $6.19 per MMBtu of natural  gas.  The 2004 PV-10 Value was
negatively  affected  as  certain of our NYMEX oil  differentials  were worse at
December 31, 2004 than they averaged during 2004 or in prior years. If the PV-10



Value  had been  calculated  at  December  31,  2004  using  average  NYMEX  oil
differentials  during 2004, that value would have been approximately $89 million
higher than the PV-10 Value calculated using year-end differentials.

     Following is a preliminary  reconciliation  of the Company's proved reserve
quantities between December 31, 2003 and December 31, 2004:

Management Comments
- -------------------

     Gareth Roberts,  Chief Executive Officer,  said: "Our core operations,  the
tertiary  operations in  Mississippi,  are  continuing to perform well. We added
approximately  18.7 MMBbls of reserves at  Brookhaven  Field in 2004, a field at
which we commenced  carbon dioxide  injections in January 2005. With the sale of
our offshore  properties  in mid 2004,  we are able to focus our  attention  and
capital on these core properties.  We are also escalating our development of our
Texas Barnett Shale acreage, with 25 wells scheduled for 2005. This area is also
performing  well,  as evidenced by the 45 Bcf increase in reserves  during 2004.
Our overall finding and development  cost, helped by the addition of reserves at
Brookhaven, was very good at around $5.35 per BOE. Including increases in future
development  costs, the all-in  incremental cost of reserve  additions for us is
averaging  just  under  $8.00 per BOE for the last three  years,  similar to our
current  depreciation  and depletion rate. This is an excellent  result,  in our
opinion, and provides  justification for our strategy of adding reserves through
CO2 tertiary projects.  With the strong oil prices and our inventory of low-risk
tertiary projects, our future continues to look very positive."
