Item 5.  Other Events and Regulation FD Disclosure.

On October 2, 2002, St. Mary Land & Exploration Company announced that its
wholly owned subsidiary Nance Petroleum Corporation has signed a Purchase and
Sale Agreement to acquire oil and gas properties with an estimated 61 BCFE of
proved reserves, 97% developed, from Burlington Resources Oil & Gas Company
LP, a wholly owned subsidiary of Burlington Resources Inc., for $76.35 million
in cash. The acquisition is valued effective as of July 1, 2002 with revenues
and expenses from the properties from that date until the date of closing to be
allocated to Nance Petroleum through a purchase price adjustment. Payment for
the properties will be made from cash on hand in addition to funds to be
obtained under St. Mary's existing revolving credit facility. The properties are
in the Williston Basin of Montana and North Dakota, and currently produce an
estimated 3,100 barrels of oil and 3,300 Mcf of gas per day. The acquisition is
expected to close December 3, 2002 upon completion of customary due diligence.
St. Mary has hedged 100% of the estimated production for calendar years 2003 and
2004. Oil is hedged at an average NYMEX price of $26.63 and $23.87 per barrel,
respectively and natural gas is hedged at an average price of $3.04 per Mcf,
indexed to CIG Rockies for the two-year period.

This report contains forward-looking statements. These statements involve known
and unknown risks, which may cause St. Mary's actual results to differ
materially from results expressed or implied by the forward-looking statements.
These risks include such factors as the uncertain nature of the expected
benefits from the acquisition of oil and gas properties, the pending nature of
the reported acquisition transaction and the ability to complete the
transaction, the volatility and level of oil and natural gas prices, production
rates and reserve replacement, reserve estimates, drilling and operating risks,
market conditions for the acquisition of oil and gas properties, competition,
litigation, environmental matters, the potential impact of government
regulations, and other matters discussed under the "Risk Factors" section of St.
Mary's 2001 Annual Report on Form 10-K filed with the SEC. Although St. Mary may
from time to time voluntarily update its forward- looking statements, it
disclaims any commitment to do so except as required by securities laws.
