BRIGHAM  EXPLORATION  REPORTS  STRONG  SECOND  QUARTER & PROVIDES  THIRD QUARTER
FORECAST

================================================================================

      Austin, TX -- August 12, 2003 -- Brigham Exploration Company (NASDAQ:BEXP)
today  announced  its  financial  results for the quarter  ended June 30,  2003.
Highlights of Brigham's financial performance for the quarter include:

o     Production  volumes  increased  6% over  second  quarter  2002  volumes to
      average 28.9 MMcfe/d;

o     38% growth in revenue  over  revenue  in the  second  quarter  2002 due to
      increased production and higher realized natural gas and oil prices ($4.66
      vs. $3.57 per Mcfe); and

o     116%  increase in operating  income to $4.9 million in the second  quarter
      2003 versus $2.3 million in the second quarter 2002.

SECOND QUARTER 2003 RESULTS

      Average net daily production for the second quarter 2003 was 28.9 MMcfe/d,
compared  to 27.3  MMcfe/d  for the  second  quarter  last  year.  Year to date,
Brigham's  net  daily   production  has  averaged  30.1  MMcfe/d,   relative  to
26.3MMcfe/d in 2002.

      Revenue  from the sale of oil and  natural  gas during the second  quarter
2003 was $12.1  million.  This  represents a 38% increase  over revenue from the
sale of oil and natural gas during last year's second quarter. Approximately 84%
of the increase in revenue for the second quarter 2003 was due to an increase in
Brigham's  average  realized sales price for oil and natural gas and 16% was due
to an increase in production volumes.

      Production costs, which include lease operating expenses, ad valorem taxes
and production taxes, for the second quarter 2003 were $2.1 million, up 60% when
compared to last year's second  quarter  production  costs of $1.3  million.  An
increase in lease operating  expenses,  due to an increase in workover activity,
represented  approximately 49% of the increase.  Higher ad valorem taxes, due to
higher property  valuations,  represented  approximately 12% of the increase and
higher  production  taxes,  due to an increase in Brigham's  realized  pre-hedge
sales price for natural gas and oil, represented 39% of the increase.

      General and administrative  expenses for the second quarter 2003 were $1.2
million  compared to $1.7 million in the second  quarter last year.  General and
administrative  expenses  for the  second  quarter  2002  included  a charge for
non-cash  compensation  expense of $596,000.  Excluding  this  non-cash  charge,
general and  administrative  expenses  for the second  quarter  2003 were up 6%.
Depletion  expenses for the second  quarter  2003 were $3.8 million  compared to
$3.4 million in the second quarter last year.  Approximately 49% of the increase
in depletion  expenses was due to an increase in production volumes while 51% of
the increase was the due to a 6% increase in Brigham's depletion rate.

      Lower average  outstanding  debt balances for the quarter  combined with a
decrease in Brigham's  weighted  average  interest rate on its outstanding  debt
resulted in a 25% decrease in Brigham's  interest expense for the second quarter
2003.  Interest expense for the second quarter 2003 was $1.2 million compared to
$1.6 million  during last year's  second  quarter.  Brigham's  weighted  average
interest rate on its outstanding borrowings for the second quarter 2003 was 5.9%
and its weighted average outstanding debt balance was $77.5 million.

      Net income to common  stockholders  for the second  quarter  2003 was $2.4
million  ($0.10 diluted  earnings per share)  compared to $61,000 ($0.00 diluted
earnings per share) in the second quarter last year.

      Net capital expenditures for oil and natural gas activities for the second
quarter 2003 were $9.9 million.  This  included $7.5 million for drilling,  $1.2
million for land and geological and geophysical activities,  and $1.4 million in
capitalized  interest and overhead  expenses.  Brigham also received $201,000 in
reimbursements  and proceeds from  participants  in Brigham  generated  projects

THIRD QUARTER 2003 FORECAST

      The  following  forecasts  and  estimates of Brigham's  third quarter 2003
results are forward looking  statements  subject to the risks and  uncertainties
identified in the "Forward  Looking  Statements  Disclosure"  at the end of this
release.

      Brigham currently expects third quarter 2003 production volumes to average
between  27.5 and 31.5  MMcfe/d,  65% of which  consists of natural gas. For the
third quarter 2003,  lease-operating  expenses,  including ad valorem taxes, are
projected  to be $0.39  per Mcfe and  Brigham  estimates  that it will  spend an
additional $157,000 for workover  operations.  Production taxes are projected to
be  5.5%  of  pre-hedge   oil  and  natural  gas   revenues,   net  general  and
administrative  expenses are  projected  to be $1.2 million  ($0.42 to $0.48 per
Mcfe),  depletion expenses are projected to be $1.46 per Mcfe,  depreciation and
amortization  expenses  are  projected  to be $192,000  and  accretion  of asset
retirement obligation is expected to be $36,000.

      Based on these  production and cost estimates and an assumed average NYMEX
prices of $ 4.99 per MMBtu for  natural  gas and $28.07 per barrel for oil,  and
taking into account current hedging  contracts  outstanding,  Brigham  forecasts
revenue of between $11.0 and $12.8 million and operating  income of between $4.2
and $5.2 million for the third quarter 2003.
