                 BRIGHAM EXPLORATION REPORTS YEAR END RESULTS
                   INCLUDING RECORD 2004 FINANCIAL RESULTS

     AUSTIN, Texas, March 3 /PRNewswire-FirstCall/ -- Brigham Exploration
Company (Nasdaq: BEXP) today announced its financial results for the fiscal year
and quarter ended December 31, 2004 and its year-end reserve numbers.

     Highlights from our performance for 2004 include:

     -- 15% growth in 2004 production over production in 2003;

     -- 40% growth in revenue to $72.2 million over revenue in 2003 of
        $51.7 million; and

     -- 28% growth in operating income to $27.9 million over operating income
        in 2003 of $21.8 million.

     YEAR-END 2004 RESULTS
     Average net daily production volumes for 2004 were 34.1 MMcfe per day
compared to 29.7 MMcfe per day in 2003. Revenues from the sale of oil and
natural gas, net of hedging, grew 39% to $71.7 million in 2004 compared to $51.5
million last year. Higher production volumes for 2004 resulted in an increase in
revenue of approximately $9.6 million while a 14% increase in our average
equivalent sales price combined with a decrease in hedging losses increased
revenues by $10.6 million. Our average realized prices for 2004 were $5.84 per
Mcf for natural gas and $35.17 per barrel for oil, compared to $4.92 per Mcf and
$28.17 per barrel in 2003. Our average realized price for 2004 includes losses
from the cash settlement of hedging transactions of $0.21 per Mcf for natural
gas and $4.96 per barrel for oil compared to $0.76 per Mcf for natural gas and
$2.62 per barrel for oil in 2003.

     Production cost, which includes lease operating expenses and production
taxes, were up 21% in 2004 and up 4% on a unit basis. An increase in costs for
compressor rental and maintenance and saltwater disposal and an increase in
production taxes due to an increase in the sales price we received from the sale
of oil and natural gas were the primary reasons for the increase in our unit
production costs.

     General and administrative expenses for 2004 were up 20% when compared to
2003. General and administrative expenses for 2004 included approximately
$399,000 paid to outside consultants and our independent public accountants for
the implementation of Section 404 of Sarbanes-Oxley and $181,813 related to the
settlement of a legal dispute over the ownership of a well. Additional items
that led to higher general and administrative expenses for the fourth quarter
were increases in employee payroll and benefit expenses and fees paid to our
external reserve engineers. Due to these higher costs, general and
administrative expenses on a unit basis increased 5% in 2004 to $0.44 per Mcfe.

     Depletion of oil and natural gas properties for 2004 was $28.8 million
($2.35 per Mcfe) compared to $17 million ($1.59 per Mcfe) in 2003. An increase
in production volumes accounted for 21% of the increase, while an increase in
our depletion rate accounted for the remaining 79%. The increase in our
depletion rate was due to a 15 Bcfe revision to our proved reserves at year-end
2004, an increase in finding and development costs in 2004 and an increase in
future development costs associated with our year-end 2004 reserves.



     Interest expenses for 2004 were $3.1 million. The 35% decrease in interest
expenses was primarily due to a decrease in our weighted average debt
outstanding for 2004 combined with a lower interest rate that we paid on those
outstanding borrowings.

     We recorded deferred income tax expenses of $9.1 million in 2004 compared
to an income tax benefit of $1.6 million in 2003. Net income available to common
stockholders for 2004 was $16.4 million ($0.39 diluted earnings per share)
compared to net income of $14.8 million ($0.53 diluted earnings per share) in
2003.

     Our capital expenditures for oil and natural gas activities in 2004 and
2003 were:

                                                             (in millions)

     FOURTH QUARTER 2004 RESULTS
     Net daily production volumes for the fourth quarter 2004 were 34.1 MMcfe
per day and were 16% higher when compared with production volumes in last year's
fourth quarter. Higher production volumes, combined with higher commodity prices
and a decrease in losses due to the settlement of hedging contracts led to a 70%
increase in revenue from the sale of oil and natural gas.

     Production cost for the fourth quarter 2004 were $2.5 million ($0.81 per
Mcfe) and 85% higher than production costs in the fourth quarter last year. On a
unit basis, lease operating expenses for the fourth quarter 2004 were $0.59
compared to $0.44 in last year's fourth quarter. The primary reasons for the
increase in lease operating expense were due to higher costs for salt-water
disposal, compressor rental and maintenance, well service and repair and an
increase in ad valorem taxes. Production taxes for the fourth quarter 2004 were
$673,000 compared to $180,000 in the fourth quarter last year. On a unit basis,
production taxes for the fourth quarter 2004 were $0.22 compared to $0.07 in
last year's fourth quarter. Production taxes in the fourth quarter of 2003
included a reclassification of a credit that we received from the settlement of
a gas imbalance liability with one of our participants. This reclassification
resulted in a decrease in our total production taxes and production taxes on a
unit basis in the fourth quarter of 2003. The credit, which based on preliminary
settlement information was booked in the third quarter 2003 as additional
revenue, was reclassified out of revenue as a reduction to production taxes in
the fourth quarter. Due to the reclassification from revenue to production taxes
both our production taxes and our production taxes on a per unit basis for the
fourth quarter 2003 appear low.



     General and administrative expenses for the fourth quarter 2004 were up 55%
when compared to general and administrative expenses in the fourth quarter of
last year. General and administrative expenses for the fourth quarter 2004
included approximately $261,000 paid to outside consultants and our independent
public accountants for the implementation of Section 404 of Sarbanes-Oxley and
approximately $181,813 related to the settlement of a legal dispute over the
ownership of a well. Additional items that contributed to the increase in
general and administrative expenses were increases in financial reporting
expenses and fees paid to our external reserve engineers. Due to these higher
costs, general and administrative expenses on a unit basis increased 32% in the
fourth quarter 2004 to $0.54 per Mcfe.

     Depletion expense for the fourth quarter 2004 was $12.5 million ($4.06 per
Mcfe) compared to $5.1 million ($1.93 per Mcfe) in the fourth quarter last year.
Higher production volumes in the fourth quarter represented 11% of this change,
while an increase in our depletion rate represented 89% of the increase in our
depletion expense.

     A decrease in our weighted average subordinated notes outstanding combined
with a decrease in the interest rate that we paid on those notes and an increase
in the amount of interest that we capitalized in the fourth quarter of 2004 were
the primary reasons for the decrease in our reported interest expense for the
fourth quarter 2004. Interest expenses for the fourth quarter 2004 were
$636,000, compared to $1 million in 2003.

     We recorded deferred income tax expenses of $1.9 million in the fourth
quarter of this year, compared to an income tax benefit of $1.6 million in the
fourth quarter 2003. We reported net income available to common stockholders of
$1.8 million ($0.04 per diluted share) for the fourth quarter 2004 versus net
income of $3.6 million ($0.10 per diluted share) for the prior year period.

     Our capital expenditures during the fourth quarter of 2004 and 2003 were:

     FULL YEAR 2005 AND FIRST QUARTER 2005 FORECAST
     The following forecasts and estimates of our full year 2005 production
volumes and first quarter 2005 results are forward looking statements subject to
the risks and uncertainties identified in the "Forward Looking Statements
Disclosure" at the end of this release.



     In addition to providing guidance for the first quarter 2005, we have
elected to provide full year production guidance for 2005. We currently expect
to grow production volumes in 2005 by 10% to 15% relative to our 2004
production. This would result in average daily production of between 37.5 and
39.2 MMcfe per day (78% natural gas) for 2005.

     We currently expect first quarter 2005 production volumes to average
between 28 and 32 MMcfe per day (75% natural gas). For the first quarter 2005,
lease operating expenses are projected to be $0.67 per Mcfe, production taxes
are projected to be approximately 5.5% of pre-hedge oil and gas revenues, and
general and administrative expenses are projected to be $1.3 million ($0.52 to
$0.45 per Mcfe). Based on these production and cost estimates, assumed average
NYMEX prices of $6.32 per MMBtu for natural gas and $47.45 per barrel for oil,
and taking into account our current outstanding hedging contracts, we forecast
that our first quarter revenue will be between $16.3 and $18.7 million and
operating income will be between $6.2 and $7.6 million.

     Gene Shepherd, Brigham's Chief Financial Officer, commented, "2004 was
obviously a disappointing year for the company in terms of our drilling results.
However, 2004 was an outstanding year for the company from the standpoint of our
financial performance. A combination of strong commodity prices, production
growth and our ability to hold our costs relatively flat all contributed to
record revenue and operating income. Furthermore, we exited 2004 with one of the
strongest balance sheets that we have had in the company's history. The
company's strong underlying financial performance and it's strong balance sheet
should allow it to continue to benefit from Brigham's large and growing
inventory of exploration and development prospects in this outstanding commodity
price environment."

     2004 PROVED RESERVES
     Our estimated net proved reserves volumes at December 31, 2004 totaled
121.3 Bcfe. Our estimated net proved developed reserves at December 31, 2004
totaled 60.2 Bcfe and our net proved undeveloped reserves totaled 61.1 Bcfe.
During 2004, we added approximately 14.4 Bcfe in total proved reserves in our
Texas Gulf Coast, Anadarko Basin and West Texas 3-D seismic projects. Our 2004
drilling program generated proved reserve additions that replaced 117% of our
12.3 Bcfe of reserve volumes produced during the year. However, reserve
revisions at year-end 2004 totaled 15 Bcfe. These revisions resulted in large
part from proved undeveloped wells drilled during 2004 at our Mills Ranch and
Floyd fields. In addition, our late 2003 Floyd South discovery well, and its
development well drilled in early 2004, both underperformed. In total, these
revisions accounted for 83% of the total revisions. Approximately 84% of our
year-end 2004 reserve volumes are natural gas and 50% are proved developed.

     At year-end 2004, the pre-tax present value ("Pre-tax PV10% Value") of our
estimated proved reserves was $294 million. Our Pre-tax PV10% Value at year-end
2003 was $344 million. Our Pre-tax PV10% Value for 2004 was calculated using a
Henry Hub natural gas price of $6.185 per MMBtu and a West Texas Intermediate
Sweet price of $43.46 per barrel versus a Henry Hub natural gas price of $5.825
per MMBtu and a West Texas Intermediate Sweet price of $32.55 per barrel that
were used for the 2003 year-end.



     Bud Brigham, the Chairman and CEO stated, "While we had a number of
accomplishments during 2004, it was a very disappointing and we believe
anomalous year in terms of reserves and finding costs. During most of the year
we failed to achieve the drilling successes, both developmental and exploratory,
that we have historically delivered. That changed late in the year, particularly
with regard to our Sartwelle #3 Appling Deep Field discovery, which has the
potential to become the largest field discovery in our history. However, this
discovery occurred too late in the year to materially impact our 2004 reserves,
though we expect it to have a very positive impact on our 2005 results.

     "Thus, for the first time in our fourteen-year history, our reserves at
year-end were actually lower than that of the prior year. There are a number of
contributing factors. First, we aggressively drilled our PUD's, with
approximately 50% of our capital spent developing reserves already in our 2003
year-end reserve report. Unfortunately, several of our large proved undeveloped
wells generated surprising results, despite being direct offsets to very strong
producers, negatively impacting our year-end reserves.

     "Second, in prior years we drilled significant discoveries that elevated
our overall results. In 2004 these came late in the year with our Sullivan C #30
well in our Triple Crown North joint venture, and with the Sartwelle #3 Appling
Deep Field discovery. However, because these wells came in so late in the year
their impact was limited. In the case of the Sartwelle #3 discovery, only 1.9
net Bcfe made our 2004 reserve report, thus we expect this field discovery to
have a positive impact on our 2005 performance.

     "Since our first third party reserve report in 1992, inclusive of 2004,
we've averaged a total proved all-sources finding cost of $1.79. The last
disappointing year we had for finding costs was 1998. Subsequent to 1998, we
generated five consecutive years of attractive finding costs and reserve growth.
Since then, inclusive of 2004, our all sources total proved finding costs has
averaged $1.98 per Mcfe. As was the case in 1998, we believe that many of the
factors that negatively impacted 2004, position us for a very strong rebound in
both reserves and finding costs in 2005."
