FOR IMMEDIATE RELEASE

                        ST. MARY REPURCHASES SHARES FROM
                    FLYING J OIL & GAS AND BIG WEST OIL & GAS

DENVER, February 9, 2004 - St. Mary Land & Exploration Company (NYSE: SM)
announced that earlier today the Company repurchased from Flying J Oil & Gas
Inc. and Big West Oil & Gas Inc. 3,380,818 restricted shares of St. Mary
common stock for a total of $91,000,000, or $26.92 per share. St. Mary issued
the shares to Flying J and Big West on January 29, 2003 in connection with St.
Mary's acquisition of oil and gas properties. In addition to issuing the shares,
St. Mary loaned Flying J and Big West $71,594,000. This loan was completely
repaid by Flying J and Big West as part of the share repurchase transaction.
Accrued interest, which has not been recorded by the Company for financial
reporting purposes due to the non-recourse nature of the loan, was forgiven. The
$19,406,000 cash payment for the share repurchase, net of the loan repayment
from Flying J and Big West, was funded from the Company's existing cash balances
and borrowings under its bank credit facility.

Mark Hellerstein, St. Mary's Chairman, President and CEO commented, "We are
pleased the Flying J transaction has resulted in a very good outcome for both
ourselves and Flying J. We believe the share repurchase will be accretive to
earnings and EBITDAX per share in 2004. It is also being made at a time when we
are able to use our cash on hand to fund a significant portion of the net
repurchase price. A side benefit to the repurchase will be a simplification of
our balance sheet."
