FOR IMMEDIATE RELEASE

ST. MARY ANNOUNCES 2004 CAPITAL  EXPENDITURES BUDGET, YEAR END 2003 RESERVES AND
                           PROVIDES OPERATIONS UPDATE

DENVER, January 22, 2004 - St. Mary Land & Exploration Company (NYSE: SM)
announced today that its estimated proved oil and gas reserves as of December
31, 2003 increased 21% to 594 BCFE, 89% which are proved developed, from 491
BCFE as of year-end 2002.

St. Mary also announced that its capital expenditures budget for 2004 is $273
million. The 2004 budget represents a 16% increase from the $235 million
forecasted capital expenditures for 2003. The budget includes $173 million for
exploration and development, which is a 9% increase over the estimated $158
million spent for exploration and development in 2003. The Company is budgeting
$100 million for property acquisitions in 2004. Approximately 34% of the
exploration and development budget is being allocated to the Mid-Continent
region, 30% to the Rockies region (including the Williston Basin), 12% to the
ArkLaTex region, 11% to the Gulf Coast and Gulf of Mexico region, 6% to the
Permian Basin and 7% to coalbed methane projects. The amount and allocation of
actual capital expenditures in 2004 will depend upon a number of factors,
including the impact of oil and gas prices and the availability of attractive
acquisition opportunities.

The Company updated its forecast for the fourth quarter and full year of 2003 as
follows:

                                             4th Quarter             Year
                                             -----------             ----
   Production                             19.1 - 19.3 BCFE     76.9 - 77.1 BCFE
   Lease operating expenses,
      including production taxes and
      transportation                     $1.04 - $1.09/MCFE   $1.15 - $1.20/MCFE
   General and administrative exp.       $0.38 - $0.42/MCFE   $0.31 - $0.35/MCFE
   Depreciation, depletion & amort.  $1.10 - $1.15/MCFE   $1.05 - $1.10/MCFE

General and administrative expenses are above previous Company forecasts
primarily due to the increased cost of incentive-based compensation plans during
a year when the Company's net asset value has increased significantly as the
result of low cost reserve additions. The Company's performance-based
compensation is impacted by the 21% growth in proved reserves and the 40%
increase in production achieved in 2003.



The Company's forecast for the first quarter and the full year of 2004 is as
follows:

                                             1st Quarter             Year
                                             -----------             ----
   Production                               18 - 20 BCFE          78 - 82 BCFE
   Lease operating expenses,
      including production taxes and
      transportation                     $1.15 - $1.25/MCFE   $1.15 - $1.25/MCFE
   General and administrative exp.       $0.35 - $0.40/MCFE   $0.32 - $0.37/MCFE
   Depreciation, depletion & amort.  $1.05 - $1.10/MCFE   $1.10 - $1.20/MCFE
