FOR IMMEDIATE RELEASE

ST. MARY ANNOUNCES 2002 CAPITAL EXPENDITURES BUDGET, YEAR END 2001
                           RESERVES AND OTHER MATTERS

DENVER, February 5, 2002 - St. Mary Land &Exploration Company (Nasdaq: MARY)
announced today that its capital expenditures budget for 2002 is $164 million.
The 2002 budget represents a 10% decrease from the $182 million forecasted
capital expenditures for 2001. The budget includes $104 million for exploration
and development and $60 million for property acquisitions. Approximately 32% of
the exploration and development budget is being allocated to the Mid-Continent
region, 21% to the Williston Basin, 17% to the Gulf Coast and Gulf of Mexico
region, 13% to the ArkLaTex region, 9% to the Permian Basin and 8% to
unconventional gas projects.

St. Mary also announced that oil and gas reserves at December 31, 2001 increased
9% from year end 2000 to 383 BCFE, which is net of a year-end 2001 reserve
reduction of 32 BCFE due to the difference in commodity prices at year-end 2001
versus prices at year-end 2000. The Company replaced 165% of its estimated 2001
production (225% excluding the 32 BCFE adjustment due to commodity prices) at an
all-inclusive finding cost of $2.03 per MCFE. Excluding the $10.8 million spent
in 2001 on pre-production costs for unconventional gas properties, the finding
cost was $1.91 per MCFE. Adding back the 32 BCFE adjustment due to commodity
prices, finding costs were $1.50 per MCFE including the pre-production costs for
unconventional gas properties, and $1.41 per MCFE excluding those costs.

St. Mary announced it has sold the remaining shares of KMOC stock, which it
acquired from the sale of its interest in the Chernogorskoye Russian oil
project. Proceeds, net of commissions were $2.5 million resulting in a first
quarter 2002 gain of approximately $844,000.

St. Mary previously hedged a portion of its oil and gas production with Enron
North America Corp., but under the terms of the contracts elected to terminate
the contracts in November 2001 with mark-to-market unrealized undiscounted hedge
amounts becoming due at that time. Since the commodity hedges with Enron North
America Corp. may not be collectible, St. Mary is required by accounting rules
to recognize a $1.6 million pre-tax non-cash charge to earnings at December 31,
2001. As the Enron hedges mature over their original lives, non-cash gains equal
to the charge recognized in 2001 will be realized. It is estimated that 80% of
the gain will be realized in 2002 and 20% will be realized in 2003.

 Management of St. Mary believes the growing demand for natural gas in the
United States under normal economic conditions can only be met by the
development of unconventional reserves that have until now been marginally
economic. The Company has acquired leases and options to earn leases in the
Rocky Mountain States on more than 135,000 acres of prospective gas reserves in
coal beds and tight gas sands in anticipation of improving commodity prices.
Preliminary production testing and permitting investigations are currently being
conducted. The Company spent $10.8 million on these projects in 2001 and has
included $8.5 million for these projects in its 2002 capital expenditures
budget.

The Company updated its forecast for the fourth quarter and full year of 2001 as
follows:
