DENVER, April 17, 2003 - St. Mary Land & Exploration Company (NYSE: SM)
today provided an update of its operations for the first quarter of 2003.

During the first quarter 2003 St. Mary participated in the drilling of 34 wells
of which 29 were completed as producers (85% success rate). Significant wells
completed in the Mid-Continent region were the Brothers 2-20 (St. Mary 34%) in

in the Trinidad field had an initial production rate of 3,800 MCFED. The Company
also participated in the recompletion of 15 wells with an 87% success rate.

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

                                       1st Quarter            Year
                                       -----------            ----
Oil & Gas Production               17.5 - 18.5 BCFE       70 - 75 BCFE
Lease operating expenses,
   including production taxes and
   transportation                      $1.17 - $1.23/MCFE     $1.22 - $1.32/MCFE
General and administrative exp.        $ .24 - $ .28/MCFE     $ .21 - $ .25/MCFE
Depreciation, depletion & amort.   $1.00 - $1.10/MCFE     $1.00 - $1.10/MCFE

The first quarter 2003 production forecast includes engineering estimates of
production from the Flying J properties which were acquired on January 29, 2003.
Actual production received from these properties could vary from the engineering
estimates.



St. Mary received proceeds of $898,000 from the grant of a 3-D seismic option to
Seismic Exchange, Inc. covering the Company's 24,914 fee acreage position in St.
Mary Parish, Louisiana and the grant of a lease option covering open acreage. If
a lease is issued, in addition to its royalty the Company will receive a right
to participate as a working interest owner for up to 25%. The Company will also
receive a license to the 3-D data covering its fee acreage position. This 3-D
survey is part of a larger 300 square mile shoot with data acquisition and
processing on the St. Mary acreage expected to be completed this year. Mark
Hellerstein, Chairman, President and CEO, stated, "This will be the first time
we will have fully imaged our fee acreage position with 3-D seismic data. We are
hopeful that this data will help generate renewed exploration activity on our
historically prolific property."

David W. Honeyfield will be joining St. Mary to assume the position of Vice
President- Finance, Treasurer and Secretary to replace Richard C. Norris who is
resigning. Mr. Honeyfield has been the Controller, Chief Accounting Officer and
Corporate Secretary for Cimarex Energy Co. since April 2002. For the previous
eleven years, he was with Arthur Andersen LLP in Denver, most recently as Senior
Audit Manager.

The Company has reached an agreement to settle its claim against Cliffs Drilling
Company, relating to excess drilling costs and loss of downhole reserves from
underground mechanical problems of the South Horseshoe Bayou #1 well in 1996, in
the amount of $4,470,000, net of amounts to be paid to partially reimburse its
insurance underwriters for amounts previously paid to St. Mary for the excess
drilling costs. The Company will record this as revenue in the second quarter.

St. Mary is scheduled to release first quarter 2003 earnings after the close of
trading on the NYSE on May 7, 2003. The teleconference call to discuss first
quarter results is scheduled for May 8, 2003 at 8:00 am (MDT). The call
