Exhibit 99.1 For Information --------------- Mark A. Hellerstein Robert T. Hanley 303-861-8140 FOR IMMEDIATE RELEASE ST. MARY PROVIDES OPERATIONS UPDATE, UPDATES GUIDANCE AND SCHEDULES SECOND QUARTER 2004 EARNINGS CONFERENCE CALL FOR AUGUST 5, 2004 DENVER, July 16, 2004 - St. Mary Land & Exploration Company (NYSE: SM) today provided an update of its operations for the second quarter of 2004 and updated its guidance for the second quarter and full year 2004. In addition, St. Mary has scheduled its second quarter 2004 earnings conference call for August 5, 2004. During the second quarter 2004 St. Mary participated in the drilling of 41 non coalbed methane wells, of which 35 were completed as producers (85% success rate). At the end of the second quarter, 37 wells were being completed and 20 were drilling. During the second quarter 28 wells were recompleted with a 64% success rate. The Company also participated in the drilling of 29 coalbed methane wells. MID-CONTINENT REGION In the Mid-Continent region there were 59 active wells during the second quarter with 19 successful completions, one dry hole and 39 wells drilling or being completed at the end of the quarter. Completed wells during the second quarter include the Radtke 1-15 in the Hyers field (SM 40% WI) completed at 3,300 MCFED and in NE Mayfield the Keathley 1-8 (SM 10% WI) completed at 5,300 MCFED and the Betty 1-19 (SM 55% WI) completed at an initial rate of 3,000 MCFED. At the end of the second quarter there were 11 wells completing and five wells drilling in NE Mayfield. Pay has now been established in the Lower Morrow, Upper Morrow, Atoka and most recently the Granite Wash formations. Numerous prospective intervals are being tested as wells are drilled further from existing locations than was done in prior periods due to the competitive nature of the play. Consequently, a backlog of activity has accumulated. However, zones tested to date suggest initial well production rates generally in the 2-5 MMCFED range, which is somewhat less than the historic averages at Northeast Mayfield.ROCKIES REGION During the second quarter there were 19 active non coalbed methane wells in the Rockies region. Six wells were successful completions, there were two dry holes, eight wells were being completed and three wells were drilling at June 30. In the Williston Basin, the Asbeck 15-35 in the Ridgelawn field (SM 100% WI) was completed in the Red River formation at a rate of 590 BOPD and 670 MCFD. The Franz 14-8H (SM 100% WI) was completed in the Bakken dolomite at an initial rate of 650 BOPD. Drilling has begun in the Company's Hanging Woman coalbed methane program in the northern Powder River Basin. The drilling program is on schedule to complete the 108 planned wells reflected in the Company's 2004 capital expenditures budget. The pipeline to connect the program to the main trunk line is currently being constructed and is on schedule to be completed by December 1, 2004. To date, 18 wells have been drilled and are scheduled to be completed prior to completion of the pipeline. Currently, two drilling rigs are operating in the program. The Company also participated in 11 coalbed methane wells in the Doty Mountain program in the Greater Green River Basin. ARKLATEX REGION Seven wells in the ArkLaTex region were completed as producing wells during the second quarter, with one dry hole. Three wells are currently being completed and two are drilling. In the horizontal James Lime Spider field, the Dave Brown No 1-H (SM 100% WI) was completed at a rate of 3,300 MCFED and the Jefferson No 1-H (SM 100% WI) was completed at a rate of 2,200 MCFED. The Lawson No. 2 well in the Bridges East field (SM 19% WI) was completed at a rate of 2,700 MCFED. GULF COAST REGION The Delambre #1 (formerly the David #1) in the Judge Digby field is currently producing at a rate of 18,000 MCFED from the C sand (SM 6.5% WI). The well has 136 feet of B sand (SM 11.5% WI) which will be completed once the C sand is depleted. An option to lease 2,845 acres of the Company's fee acreage position in St. Mary Parish, Louisiana, was exercised during the second quarter. The option was granted as part of a 3-D survey conducted over all of St. Mary's 24,914 acres of fee lands. In addition to a royalty interest, the Company will receive the right to participate as a working interest owner for up to 25% in each well drilled on the leased acreage. The Company updated its forecast for the second quarter and full year of 2004 as follows: 2nd Quarter Year ----------- ---- Oil and gas production 17.5 - 18.5 BCFE 72.0 - 74.0 BCFE Lease operating expenses, including production taxes and transportation $1.17 - $1.22/MCFE $1.25 - $1.35/MCFE General and administrative expense, excluding mark-to-market of NPP $0.29 - $0.34/MCFE $0.25 - $0.29/MCFE Depreciation, depletion & amort. $1.10 - $1.15/MCFE $1.15 - $1.25/MCFE Mark-to-market of NPP expense $3.5 - $4.0 million The Company's production forecast is being revised to eliminate 4 BCFE of production that was previously expected to result from budgeted 2004 acquisitions, the delay in new production from Northeast Mayfield and underperformance of certain other fields. Significant production from acquisitions is no longer anticipated in 2004 due to the current acquisition pricing environment. The forecasted production at Northeast Mayfield is below previous expectations because of the extended time necessary to complete wells due to the multiple zones currently being tested. In addition, production rates at the Terryville, Arcadia West, and "66" fields have underperformed previous expectations. In the second quarter of 2004, St. Mary realized a $3.1 million benefit attributable to State severance tax credits from production through June 2004. This benefit results in lower production tax expense for the second quarter than was previously forecast. Forecasted general and administrative expense includes $1.2 million and $1.8 million, respectively, for the second quarter and for the year 2004 for incentive compensation expense associated with the Company's new Restricted Stock Plan. The mark-to-market expense adjustment related to the Company's Net Profits Interest Bonus Plan will be shown separately in this and future releases. Previously, this item was included in general and administrative and exploration expense. The mark-to-market adjustment represents the change in the net present value of estimated future incentive compensation cash bonus payments to be made to plan participants based on the computational provisions of the plan with respect to estimated future cash flows from oil and gas properties associated with various pools under the plan. Accounting rules require the estimated market value of such estimated future payments to be recorded as a liability prior to recognizing the realized net revenues associated with the same properties. The resulting mark-to-market liability and corresponding income statement items will be separately presented in the balance sheet as a long-term liability and as a separate component of the income statement. This reclassification has the effect of reducing the previously reported general and administrative and exploration expense. In order to facilitate comparability, the following table displays historical general and administrative, exploration and mark-to-market expense after giving effect to the reclassification: G&A EXPENSE --------------- Total PER MCFE EXPL. EXP MTM ----- -------- --------- --- 2003 March 31, $5.4 million $0.34 $4.2 million $0.8 million June 30, $5.5 million $0.29 $6.3 million $0.9 million September 30, $4.8 million $0.29 $9.9 million $0.7 million December 31, $5.6 million $0.29 $5.0 million $2.9 million 2004 March 31, $5.6 million 0.36 $4.6 million $2.2 million St. Mary is scheduled to release second quarter 2004 earnings after the close of trading on the NYSE on August 4, 2004.
