Brigham Exploration Reports Year-End and Fourth Quarter 2006 Results

          AUSTIN, Texas, March 5 /PRNewswire-FirstCall/ -- Brigham Exploration Company (Nasdaq: BEXP) today announced financial results for the year-end and quarter ended December 31, 2006. 

          YEAR-END 2006 RESULTS

          Average daily production volumes for 2006 were 36.8 MMcfe per day, up 11% when compared to 2005.  Revenues from the sale of oil and natural gas including hedge settlements for 2006 were $103.6 million, which represents a 7% increase when compared to last year.  Higher production volumes and hedge settlement gains increased revenue by $11.1 million and $8.0 million, respectively, while lower commodity prices decreased revenue by $12.3 million.

          Our average realized price for natural gas in 2006 was $7.09 per Mcf, which included a $0.35 per Mcf gain associated with the settlement of our natural gas derivative contracts.  This compares to an average realized price in 2005 of $7.97 per Mcf, which included a $0.32 per Mcf loss due to the settlement of our natural gas derivative contracts.  Our average realized price for oil for 2006 was $64.39 per barrel, which included a $0.35 per Bbl gain due to the settlement of our oil derivative contracts.  This compares to an average realized price in 2005 of $51.95, which included a $2.78 per barrel loss due to the settlement of oil derivative contracts last year.

          Our production costs, which include costs for operating and maintaining (O&M expense) our producing wells, expensed workovers, ad valorem taxes and production taxes, were up $0.23 per Mcfe, or 26%, when compared to 2005.  O&M expenses increased $0.16 per Mcfe, or 34%.  Increased costs associated with salt water disposal, equipment rental, chemical testing and treating, and well service and repair accounted for 69% of the increase in O&M expense.  Ad valorem taxes increased $0.03 per Mcfe, or 33%, due to an increase in property valuations for our oil and natural gas properties due to higher commodity prices.

          Our general and administrative (G&A) expense for 2006 was 43% higher than 2005.  G&A expense increased primarily because of $1.6 million of non-cash employee compensation expense associated with our 2006 adoption of SFAS 123R, which deals with the change in accounting methodology for employee stock option expense.  G&A expense also increased because of increases in payroll and benefits associated with higher employee retention costs and, to a lesser extent, an increase in the number of employees.  These increases resulted in our G&A expense increasing by $0.14 per Mcfe, or 30%.

          Our depletion expense for 2006 was 39% higher than 2005.  Approximately 72% of the increase in our depletion expense for 2006 was due to an increase in our depletion rate while the remaining 28% of the increase was due to an increase in our production volumes.  The increase in depletion rate is attributable to an increase in finding and development costs incurred in 2006 and an increase in future development costs associated with our year-end 2006 proved reserves.

          Our net interest expense for 2006 was 143% higher than last year.  This increase was primarily due to interest incurred on our 9 5/8% senior notes due 2014 (“Senior Notes”), which we issued in April 2006.  The issuance of the Senior Notes resulted in an increase in our weighted average debt outstanding and our weighted average cost of debt.  Our weighted average debt outstanding for 2006 was $123.0 million versus $80.2 million in 2005.  In addition, we wrote-off approximately $1.0 million in subordinated note issuance costs associated with the termination of the subordinated credit facility in April 2006.

          We recorded deferred income tax expense of $12.7 million in 2006 compared to deferred income tax expense of $15.0 million in 2005.  Although overall tax expense was down relative to 2005, our effective tax rate increased due to our adoption of the Texas state margin tax in 2006, which required us to record $1.3 million of deferred margin tax in 2006 to account for the cumulative differences between book and tax accounting for periods prior to and including December 31, 2006.

          Our reported net income for 2006 was $19.8 million ($0.43 per diluted share) versus net income of $27.4 million ($0.63 per diluted share) for the same period last year.  Net income for 2006 includes $3.5 million after-tax ($5.8 million before-tax) in unrealized gains on derivatives.  Excluding the impact of unrealized hedging gains, net income for 2006 would have been $16.3 million ($0.36 per diluted share).

          As of December 31, 2006, we had $4.3 million in cash, $25.9 million of debt outstanding under our senior credit facility and a net debt to book capitalization ratio of 38%.

          In 2006, we spent $184.6 million on oil and gas capital expenditures, which represents a 56% increase from 2005.  Oil and gas capital expenditures for 2006 and 2005 were:

	Twelve Months Ended December 31,
	2006		2005
	(in thousands)
Drilling	$	142,338	$	90,873

Total oil and gas capital expenditures	$	184,584	$	118,627

          FOURTH QUARTER 2006 RESULTS

          Our average net daily production volumes for the fourth quarter 2006 were 38.8 MMcfe per day, down 5% when compared to the fourth quarter 2005. Revenues from the sale of oil and natural gas including hedge settlements for the fourth quarter 2006 were down 29% to $26.0 million when compared to the fourth quarter 2005.  Lower realized prices and production volumes decreased revenues by $12.0 and $1.9 million, respectively, while hedge settlement gains increased revenues by $3.4 million.

          Our average realized price for natural gas for the fourth quarter 2006 was $7.00 per Mcf, which included a $0.36 per Mcf gain associated with the settlement of our natural gas derivative contracts.  This compares to an average realized price in the fourth quarter 2005 of $10.02, which included a $0.71 per Mcf loss due to the settlement of our natural gas derivative contracts.  During the fourth quarter 2006, our average realized price for oil was $56.09 per barrel, which included a $1.38 per barrel gain due to the settlement of our oil derivative contracts.  This compares to an average realized price in the fourth quarter 2005 of $57.71, which included a $0.95 per barrel loss due to the settlement of our oil derivative contracts.

          Our fourth quarter 2006 production costs were up 1% on a per unit basis when compared to the fourth quarter 2005.  A $0.24 per Mcfe increase in our O&M expenses was offset by a $0.23 per Mcfe decrease in our production taxes. Increases in salt water disposal, compressor and equipment rental, and well service and repair accounted for 64% of the per unit increase in O&M expense. The decrease in production taxes is attributable to both lower production volumes and an increase in the level of severance tax refunds approved by states in the fourth quarter 2006 as compared to the fourth quarter 2005.

          Our G&A expense for the fourth quarter 2006 was 8% higher than the fourth quarter 2005.  G&A expense increased primarily because of $0.4 million of non- cash employee compensation expense associated with our 2006 adoption of SFAS 123R.

          Our depletion expense for the fourth quarter 2006 was $1.5 million higher than the fourth quarter 2005.  Depletion increased by $2.1 million due to an increase in our depletion rate and was partially offset by a $0.6 million decrease due to lower production volumes.

          Our net interest expense for the fourth quarter 2006 increased by $1.5 million.  This increase was primarily due to our higher weighted average debt outstanding and our higher weighted average interest cost associated with our Senior Notes.  Our weighted average debt outstanding for the fourth quarter 2006 was $149.6 million compared to $91.9 million for the comparable period last year.

          We recorded deferred income tax expense of $2.8 million in the fourth quarter of this year compared to deferred income tax expense of $6.5 million in the fourth quarter last year.  The decrease in our deferred income tax expense was primarily due to lower fourth quarter 2006 income before income taxes.

          Our net income for the fourth quarter 2006 was $5.0 million ($0.11 per diluted share) compared to net income of $11.9 million ($0.26 per diluted share) in the fourth quarter 2005.  Fourth quarter 2006 net income includes $1.8 million after-tax ($2.9 million before-tax) in unrealized commodity derivative gains.  Excluding the impact of these unrealized derivative gains, net income for the quarter would have been $3.2 million ($0.07 per diluted share). 

          2006 PROVED RESERVES

          Our estimated net proved reserve volumes at December 31, 2006 totaled 146.5 Bcfe of which approximately 82% was natural gas.  During 2006, we added approximately 26.5 Bcfe in net proved reserves and replaced 200% of the 13.3 Bcfe of production.  Our 2006 net proved reserve additions included 26.8 Bcfe of extensions, discoveries and other additions which were partially offset by 0.3 Bcfe of revisions to prior estimates.  Our estimated net proved developed reserves at December 31, 2006 totaled 81.0 Bcfe and our net proved undeveloped reserves totaled 65.5 Bcfe.  With net proved undeveloped reserves remaining flat from 2005 to 2006, our net proved developed reserves increased 19% from the prior year and represented 55% of total proved reserves at year- end 2006 versus 51% at year-end 2005.

	Equivalent Reserves (MMcfe)
2006 Beginning Proved Reserves		133,223
Extensions, discoveries & other additions		26,764
Revisions of prior estimates		(281	)
Production		(13,254	)
2006 Ending Proved Reserves		146,452

          At year-end 2006, the standardized measure and the pre-tax present value (“Pre-tax PV10% Value”) of our estimated proved reserves were $302.7 million and $338.5 million, respectively.  For 2006, these measures were calculated using a West Texas Intermediate Sweet price of $61.06 per barrel and a Henry Hub natural gas price of $5.48 per MMBtu.

	At December 31, 2006
Standardized measure of discounted future net cash flows	$	302.7
Add present value of future income tax discounted at 10%		34.6
FAS 143 assumption differences		1.2
Pre-tax PV10%	$	338.5

          Pre-tax PV10% Value is the estimated present value of the future net revenues from our proved oil and natural gas reserves before income taxes discounted using a 10% discount rate.  Pre-tax PV10% Value is considered a non-GAAP financial measure under SEC regulations because it does not include the effects of future income taxes, as is required in computing the standardized measure of discounted future net cash flows.  We believe that Pre-tax PV10% Value is an important measure that can be used to evaluate the relative significance of our oil and natural gas properties and that Pre-tax PV10% Value is widely used by security analysts and investors when evaluating oil and natural gas companies.  Because many factors that are unique to each individual company impact the amount of future income taxes to be paid, the use of a pre-tax measure provides greater comparability of assets when evaluating companies.  We believe that most other companies in the oil and natural gas industry calculate Pre-tax PV10% Value on the same basis.  Pre-tax PV10% Value is computed on the same basis as the standardized measure of discounted future net cash flows but without deducting income taxes. 

          FULL YEAR AND FIRST QUARTER 2007 FORECASTS

          The following forecasts and estimates of our first quarter 2007 and full year 2007 production volumes are forward looking statements subject to the risks and uncertainties identified in the “Forward Looking Statements Disclosure” at the end of this release.  We currently expect our first quarter 2007 production volumes to average between 37.5 MMcfe per day and 40.0 MMcfe per day.  We expect full year 2007 production volumes to average between 40.0 MMcfe per day and 45.0 MMcfe per day.

          For the first quarter 2007, lease operating expenses are projected to be $0.82 per Mcfe based on the mid-point of our production guidance, production taxes are projected to be approximately 5.5% of pre-hedge oil and natural gas revenues, and general and administrative expenses are projected to be $2.1 million ($0.62 to $0.58 per Mcfe). 

          MANAGEMENT COMMENTS

          Bud Brigham, Brigham’s CEO and President, commented, “During 2006, we made very substantial long-term investments in acreage, 3-D seismic, and the drilling of early wells in our emerging resource plays.  We expect these investments to pay dividends for us in 2007 and subsequent years. We also aggressively developed our proved undeveloped reserves in 2006 with very good results. While this negatively impacted our total proved finding cost, it generated strong growth in proved developed reserves. Specifically, regarding our focus plays, the Texas Frio underperformed for us during 2006.  However, we once again achieved exceptional results in the Vicksburg, including low total proved finding costs and strong rates of return on our drilling investments.  Our total proved drilling finding costs were attractive in our other focus plays including Southern Louisiana as well as the Hunton, Springer and the Granite Wash plays of the Anadarko Basin.  As evidenced by our capital plan for 2007, our drilling this year will be focused in those plays that have generated our strongest returns, led by the Vicksburg.”

          Gulf Coast Exploration Trend

          Southern Louisiana Bayou Postillion Project, Iberia Parish - Brigham has successfully production tested the Cotten Land #3, which encountered approximately 80 feet of apparent net pay in two intervals.  The Cotten Land #3 was tested from the lowest 30 feet of pay at a production rate of 12.9 MMcf of natural gas and 48 barrels of oil per day with strong pressures.  Based on the minimal pressure differences between the flowing and shut in tubing pressures, Brigham expects to produce the well at an initial rate between 15 MMcfe and 20 MMcfe per day.  Approximately 50 feet of shallower pay will remain behind pipe for future completion.  Brigham operates the Cotten Land #3 with an approximate 47% working and 33% net revenue interest, and expects the well to commence production to sales by late March or early April.   Penn Virginia (NYSE: PVA) is also a participant with Brigham in the Cotten Land wells, and operates the wells during the production phase.

          In May, Brigham plans to commence the Cotten Land #2, which is expected to test an apparent new fault block adjacent to the fault block in which Brigham drilled the Cotten Land #1 well.  The unrisked reserve potential of this apparent fault block is estimated at approximately 4 to 12 Bcfe, with results expected in June.   Following the Cotten Land #2, Brigham plans to commence the Cotten Land #4, offsetting Brigham’s previously drilled Cotten Land #1 discovery.

          Bud Brigham, the Chairman, President and CEO stated, “Six months after commencing production, our first Bayou Postillion well, the Cotten Land #1, continues to produce approximately 15 MMcfe per day, or over 4 MMcfe per day net.  By the end of the second quarter, we could have a total of three Bayou Postillion wells providing gross production of over 40 MMcfe per day, or 10 MMcfe per day net.  The two additional wells planned in 2007, if successful, could also significantly impact our third quarter production.  Given the success we’ve enjoyed here and the low total proved finding costs we achieved in this play during 2006, we are currently working to grow our activity in this area.”

          Gulf Coast Vicksburg Development

          Triple Crown Field Development - Brigham expects to drill through the Dawson Sand objective and reach total depth in the Dawson #1S by next week. The Dawson #1S is a sidetrack of the previously drilled Dawson #1 well, and offsets the Sullivan F-33.  The Sullivan F-33 has been a strong Dawson Sand producer, which commenced production at a rate of approximately 9.5 MMcfe per day, with additional apparent pay in the Loma Blanca, 9800’ and Brigham Sand intervals remaining behind pipe.  Based on mud logs and wireline logs, the Dawson #1S appears to have encountered roughly comparable 9800’ and Loma Blanca pay to that found in the offsetting wells.  Brigham retains a 100% working and 75% net revenue interest in the Dawson #1S, which is expected to commence production to sales by early April.

          In mid-March, Brigham plans to commence the Sullivan C-35.  The Sullivan C-35 is expected to develop various Upper Vicksburg intervals, including the Dawson Sand, and potentially prove up significant additional Upper Vicksburg reserves.  Results for the Sullivan C-35 are expected in May.   Following the Sullivan C-35, Brigham plans to commence the Sullivan #14 in May.  The Sullivan #14 is expected to test additional reserve potential in the Upper and Lower Vicksburg, with results for the Sullivan #14 expected in June.

          Home Run Field Development - In June, Brigham plans to commence the Sullivan #15, a significant development well in its Home Run Field.  The Sullivan #15 appears to be located in a structurally high location at various Lower Vicksburg intervals in the Home Run Field, and could potentially prove up significant additional locations and reserves.  Brigham expects to retain a 100% working interest in the Sullivan #15 subject to a 66% back-in at 350% payout.  Results are expected in July.

          Bud Brigham stated, “As has been the case in recent years, the Vicksburg was our top performer in 2006, delivering high value reserves at an approximate average proved developed finding cost of $1.73 per Mcfe and a total proved finding cost of $3.32 per Mcfe.  As we began 2006 we did not anticipate the high level of productivity demonstrated with our Dawson sand completions, nor did we anticipate the level of new reserve adds proven up during the year by our 2006 Vicksburg drilling program.  Partly as a result of this success, we believe we’ve delineated specific opportunities to convert meaningful probable and possible Vicksburg reserves to the proved category during 2007.”

          Anadarko Basin Hunton Development

          Mills Ranch Field Update - After successfully production testing the Viola in the Mills Ranch 96 #1, Brigham commenced operations to complete and eventually commingle in the more substantial apparent pay in the lower, middle and upper Hunton intervals.  These operations have taken longer than anticipated.  However, Brigham is preparing to perforate the upper Chimney Hill, Haragan and Henryhouse Hunton intervals, with stimulation planned for March 10th.  Production to sales is expected later this month.  Brigham operates the Mills Ranch 96 #1 with an approximate 68% working and 56% revenue interest, with Panhandle Royalty (Amex: PHX) participating with an approximate 10% working and 13% revenue interest.

          Brigham’s attempts to repair the casing problem in the Mills Ranch 98 #2 were unsuccessful.  As a result, a kick off plug has been set, and the company expects to re-enter and sidetrack the well at a later date.  The Mills Ranch 98 #2 was producing approximately 3.3 MMcfed prior to identifying a casing leak during the second quarter of 2006.

          Bud Brigham stated, “We’re disappointed that we were unable to repair the Mills Ranch 98 #2.  At this point, we are better off simply sidetracking around the problem area.  We will be developing an operational plan over the next several months in order to achieve the lowest cost possible for the operation, which could occur later this year.  On the other hand, we’re very eager to commence commingled production for the Mills Ranch 96 #1, which we expect to be a significant long life producer for our company.  We’re also excited about our new 180 square mile high resolution Laker 3-D seismic program, which is in the later stages of processing.  The Laker 3-D shoot was a substantial investment for our company in 2006.  We’re encouraged by the early indications regarding the quality of the imaging, and we’re hoping to receive final processed data during the second quarter.  This state-of-the-art 3-D seismic data should help us image our existing inventory of leased prospects in the trend, generate new prospects on our optioned and leased acreage, and facilitate the further development of our Mills Ranch Field.”

          Resource Plays

          Powder River Basin Mowry Shale Play Completions - Completion operations are continuing on Brigham’s first two horizontal Mowry wells.  Brigham successfully fracture stimulated the outer 415 feet of open hole interval in the Mill Trust 1-12H.  A rod pumping unit has been installed, and during the last 24 hours the well produced approximately 120 barrels of load water and 47 barrels of oil, with 400 to 500 barrels of load water remaining to be recovered.  Subsequent to testing the open hole section, Brigham will production test the remaining 885 feet of the lateral which is currently behind production casing.

          Brigham successfully fracture stimulated the 1,381 foot cased hole portion of its first horizontal Mowry well, the Krecji #3.  The Krecji was previously production tested in the outer 219 foot open hole section at rates of between 120 and 160 barrels of oil and approximately 120 Mcf of natural gas per day. After stimulating the cased hole portion, Brigham briefly tested the cased interval utilizing a submersible pump.  During this testing the cased portion produced significant volumes of load water and between 50 and 90 barrels of oil per day.  Brigham subsequently drilled out the temporary plug in order to production test the cased and uncased sections together, again utilizing a down hole submersible pump.  However, submersible pump problems have prevented Brigham from obtaining a stabilized rate; and Brigham is currently pulling the submersible pump to determine the problem.  Brigham expects to either reinsert a submersible pump or to install a more conventional rod pump.

          Powder River Basin Mowry Shale Play Drilling - Next week, Brigham expects to commence a continuous 2007 drilling program in the Mowry with the spudding of the Werner 1-14H.  The Werner 1-14H is a probable location that should further delineate the Mowry shale recoverable reserves.  If successful, it could move additional locations to the proved category.  The Werner 1-14H is expected to reach total depth in April.  Following the Werner 1-14H, Brigham plans to commence the State 1-16H, another probable location which could prove up additional locations.  The State 1-16H is expected to reach total depth in May.

          Brigham owns a 50% interest in its Mowry joint venture, with American Oil and Gas, Inc. (Amex: AEZ) retaining a 45% interest and privately-held North Finn retaining 5%. Brigham’s acreage holdings in the play are approximately 63,000 net acres.  With success, assuming 160 acre spacing, over 700 gross, or up to 393 net locations could be drilled to fully develop Brigham’s acreage position.

          Bud Brigham stated, “Although operations have proceeded very slowly due to severe winter weather conditions in Wyoming, our activity continues to generate encouragement, though the results as yet are not conclusive.  We’re intrigued by the potential provided by submersible pumping technology applied to this play.  On the other hand, thus far we’re seeing good early volumes of fluid recovery utilizing a rod pump to produce the open hole portion of the Mill Trust 1-12H well.    We believe that we’re getting close operationally to generating more definitive production data on both of these wells.  These completions, combined with the commencement of our very active eight well 2007 Mowry drilling program, could generate some excitement and meaningful reserve adds for us as we move through the year.”

          Williston Basin Bakken - Subsequent to fracture stimulation and the installation of rod pump, Brigham’s second horizontal Bakken well, the Erickson 8-17 1-H, commenced production on January 22nd at an early rate of approximately 227 barrels of oil, 100 Mcf of natural gas and 212 barrels of water per day.  The Erickson 8-17 1-H is currently producing approximately 82 barrels of oil, 42 Mcf of natural gas and 28 barrels of water per day. Brigham’s third horizontal Bakken well, the Mracheck 15-22 1-H, has been producing on a rod pump at a rate of approximately 30 barrels of oil per day prior to stimulation.  The fracture stimulation for the Mracheck is planned for this Spring.  Brigham has grown its acreage position in the Bakken to approximately 125,000 net acres, approximately 70,000 of which are in Montana, where the company controls all stratigraphic rights, and approximately 55,000 of which are in North Dakota.

          Bud Brigham stated, “We’re currently benefiting from a great deal of operational activity by other operators in the Bakken utilizing various drilling and completion techniques.  Looking ahead, we believe it’s critical that we drill and complete these wells at the lowest cost possible, and we believe we will have that opportunity later in the year.  Given the recent cost trends, the diverse operational activity in the area, and specific opportunities we’re analyzing, we’re hopeful that we’ll be resuming our Bakken drilling later this year.”
