                           --------------------------

DENVER, January 27, 2003 - St. Mary Land & Exploration Company (NYSE: SM)
announced today that its capital expenditures budget for 2003 is $225 million.
The 2003 budget represents a 16% increase from the $193 million forecasted
capital expenditures for 2002. The budget includes $135 million for exploration
and development and $90 million for property acquisitions, including the
previously announced pending acquisition of oil and gas properties from Flying J
Oil & Gas Inc. and Big West Oil & Gas Inc. which is expected to close
January 29, 2003. Approximately 33% of the exploration and development budget is
being allocated to the Mid-Continent region, 24% to the Rockies region
(including the Williston Basin), 14% to the ArkLaTex region, 13% to the Gulf
Coast and Gulf of Mexico region, 9% to the Permian Basin and 7% to
unconventional gas projects.

St. Mary also announced that its oil and gas reserves at December 31, 2002
increased 28% from 383 BCFE at year-end 2001 to 491 BCFE, 88% which are proved
developed. The Company replaced 305% of its estimated 2002 production at an
estimated all-inclusive finding cost of $1.15 per MCFE.

The Company updated its forecast for the fourth quarter and full year of 2002 as
follows:

                                                   4th Quarter           Year

Pipeline curtailments caused by the flurry of new completions in NE Mayfield in
the Anadarko Basin resulted in a loss of approximately 500 MMCFE for the
quarter. Work is in progress to increase pipeline capacity to accommodate the
new production.

St. Mary currently has the following hedges in place:

During the fourth quarter St. Mary will realize a pre-income tax gain of $3.95
million resulting from the complete liquidation of the interest rate swap
agreement entered into during the first quarter of 2002 with respect to $50
million of the $100 million in St. Mary's 5.75% senior convertible notes due
2022. Prior to the fourth quarter the Company had recorded a $4.59 million
mark-to-market unrealized derivative gain on these swap agreements. St. Mary has
separately determined that for the period from September 15, 2002 to March 14,
2003 the notes will, subject to the terms of the indenture under which they were
issued, accrue additional contingent interest at a rate of 0.50% per annum.

The Company will recognize a pre-income tax loss of $2.6 million on the sale of
its interest in Flour Bluff, a non-operated field in Nueces County, Texas,
during the fourth quarter of 2002.
