         BRIGHAM EXPLORATION REPORTS THIRD QUARTER RESULTS AND PROVIDES
                            FOURTH QUARTER FORECASTS

    AUSTIN, Texas, Nov. 2 /PRNewswire-FirstCall/ -- Brigham Exploration
Company (Nasdaq: BEXP) today announced its financial results for the third
quarter and nine months ended September 30, 2005.

    THIRD QUARTER 2005 RESULTS
    Our average daily production volumes for the third quarter 2005 were 32
MMcfed/d, down 6% when compared to last year's third quarter volumes. The
natural decline of our existing production was only partially offset by
production from recently completed wells, causing an overall decline in our
third quarter 2005 production. Additionally, we estimate that approximately 0.5
MMcfe/d of our third quarter 2005 production was lost due to the need to shut-in
wells in preparation for Hurricane Rita.

    Our revenues from the sale of oil and natural gas for the third quarter 2005
were up 46% when compared to the same period last year. A 49% improvement in the
sales price we received for our oil and natural gas combined with a 35% decrease
in losses from the settlement of derivative contracts were the primary reasons
for the increase in our third quarter 2005 revenues. These increases to revenue
were partially offset by a decrease in revenues due to lower production volumes.

    Our production costs, which include costs for operating and maintaining (O&M
expenses) our producing wells, expensed workovers, ad valorem taxes and
production taxes, were down 2% when compared to the third quarter last year. The
primary reason for this decline was a decrease in expensed workovers. This
decrease was partially offset by increases in our production taxes, ad valorem
taxes and O&M expenses. The increases in our third quarter production taxes and
ad valorem taxes were due to higher commodity prices. An increase in production
tax credits totaling approximately $488,000 offset a portion of the increases
that would have been expected, given the 41% increase in our third quarter 2005
pre-hedge oil and natural gas revenues. Our O&M expenses for the third quarter,
which includes $254,000 of costs associated with new wells that were not
producing in the third quarter last year, were up 17% when compared to last
year. Excluding the costs associated with these new wells, our O&M expenses for
the third quarter 2005 decreased by 4% when compared to the third quarter last
year. On a unit of production basis, our third quarter 2005 production costs
were $0.79 per Mcfe, up 4% when compared to the third quarter of last year.

    Our general and administrative expenses (G&A expenses) for the third quarter
2005 were up slightly when compared to our G&A expenses in the third quarter
last year. On a unit of production basis, our G&A expenses for the third quarter
2005 were up 7% when compared to last year due to lower production volumes.

    Our depletion expense for the third quarter 2005 was $8 million ($2.76 per
Mcfe) compared to $5.9 million ($1.92 per Mcfe) in the third quarter last year.
An increase in our depletion rate resulted in a $2.4 million increase in our
third quarter 2005 depletion expense. This increase was partially offset by a
decrease of $328,000 due to lower production. Our operating income for the third
quarter 2005 was $13.4 million and was 78% higher than our operating income in
the third quarter 2004.

    Our net interest expense for the third quarter 2005 was 31% higher than last
year. This increase was primarily due to a $591,000 increase in the amount of
interest expense that we paid on borrowings under both our senior credit
facility and subordinated credit agreement. An increase in the amounts we
borrowed under both our senior credit facility and subordinated credit agreement
and an increase in the rate that we paid on borrowings under our senior credit
facility due to an increase in the Eurodollar rate were the primary reasons for
this increase. Our weighted average debt outstanding for the third quarter 2005
was $92 million compared to $54.5 million last year.



    Our reported net income for the third quarter was $7.7 million ($0.18 per
diluted share) compared to net income of $4.5 million ($0.11 per diluted share)
in the third quarter last year.

    Our net capital expenditures for oil and natural gas activities in the third
quarter 2005 were $25.3 million. Net capital expenditures for the third quarter
2005 and 2004 were:

    FIRST NINE MONTHS 2005 RESULTS
    Average daily production volumes for the first nine months of 2005 were 30.5
MMcfed/d, down 11% when compared to the first nine months last year. The natural
decline of our existing production was only partially offset by production from
recently completed wells, causing an overall decline in our production during
the first nine months of 2005. Additionally, we estimate that approximately 0.2
MMcfe/d of our production during the first nine months of 2005 was lost due the
need to shut-in wells in preparation for Hurricane Rita.

    Our revenues from the sale of oil and natural gas for the first nine months
2005 were 16% higher than our revenues last year. A 26% improvement in the sales
price we received for our oil and natural gas and a 40% decrease in losses from
the settlement of derivative contracts were the primary reasons for this
increase. These increases to revenue were partially offset by a decrease in
revenue due to lower production volumes.

    Our production costs for the first nine months of 2005 were $7.1 million, up
4% when compared to the same period last year. The primary reasons for the
increase were increases in our O&M expenses and ad valorem taxes. Our O&M
expenses for the first nine months of 2005 includes $610,000 of costs associated
with new wells that were not producing during the first nine months of last
year. Excluding the costs associated with these new wells, our O&M expenses for
the first nine months of this year were up 11% when compared to the first nine
months of last year. The increase in our ad valorem taxes was due to higher
commodity prices. These increases were partially offset by decreases in our
production taxes and expensed workovers. An increase in production tax credits
totaling approximately $995,000 for the first nine months of 2005 offset a
portion of the increases that would have been expected, given the 13% increase
in our pre-hedge oil and natural gas revenues for the nine month period ended
September 30, 2005. Our production taxes for the first nine months of 2005 were
also lower due to lower production for the period. On a unit of production
basis, our production costs for the first nine months of 2005 were $0.85 per
Mcfe, up 16% when compared to the same period last year.

    General and administrative expenses for the first nine months of 2005 were
slightly lower than our G&A expenses during the first nine months of last year.
However, when compared to the first nine months of last year, our G&A expenses
on a unit of production basis for the first nine months of this year were up 13%
to $0.45 per Mcfe due to lower production volumes.



    Our depletion expense for the first nine months of 2005 was $21.6 million
($2.62 per Mcfe) compared to $16.5 million ($1.79 per Mcfe) in the first nine
months last year. An increase in our depletion rate increased our depletion
expense for the first nine months of 2005 by $6.9 million. This increase was
partially offset by a decrease of $1.8 million due to lower production. The
increase in our depletion rate was primarily the result of increased costs of
reserve additions during the first nine months of 2005. Our operating income for
the first nine months of this year was $27.4 million, up 13% when compared to
operating income during the first nine months of last year.

    Our net interest expense for the first nine months of 2005 was 5% higher
than last year. This increase was primarily due to an $889,000 increase in the
amount of interest that we paid on borrowings under our senior credit facility.
An increase in the amount we borrowed under our senior credit facility combined
with an increase in the rate that we paid on those borrowings due to an increase
in the Eurodollar rate were the primary reasons for this increase. Our weighted
average debt outstanding for the first nine months of this year was $76.2
million compared to $57.3 million last year. The increase in interest expense
was partially offset by a $515,000 increase in the amount of interest that we
capitalized during the first three quarters of this year.

    Our reported net income for the first nine months of 2005 was $15.5 million
($0.36 per diluted share) versus net income of $14.6 million ($0.35 per diluted
share) for the same period last year.

    Our year to date through September 30, 2005 net capital expenditures for oil
and natural gas activities were $84.3 million. Net capital expenditures for the
first nine months of 2005 and 2004 were:

    FOURTH QUARTER 2005 FORECAST
    The following forecasts and estimates of our fourth 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.

    We currently expect our fourth quarter 2005 production volumes to average
between 39 MMcfe/d and 41 MMcfe/d (78% natural gas). For the fourth quarter
2005, lease operating expenses are projected to be $0.53 per Mcfe based on the
mid-point of our production guidance, production taxes are projected to be
approximately 5.6% of pre-hedge oil and natural gas revenues, and general and
administrative expenses are projected to be $1.4 million ($0.38 to $0.40 per
Mcfe).

    Based on these production and cost estimates, assumed average NYMEX prices
of $12.98 per MMbtu for natural gas and $61.01 per barrel for oil, and taking
into account current derivative contracts outstanding, we forecast that our
fourth quarter 2005 revenue will be between $40.6 and $42.8 million and
operating income will be between $25 and $26.6 million.

      SUMMARY OF COMMODITY PRICE HEDGES OUTSTANDING AS OF NOVEMBER 2, 2005
                                   (unaudited)

    We use derivative instruments to manage risks associated with natural gas
and crude oil price volatility. Derivative instruments that meet the hedge
criteria in SFAS No. 133 are designated as cash-flow hedges. Derivative
instruments that do not meet the hedge criteria in SFAS No. 133 are not
designated as hedges. We used derivative instruments designated as cash-flow
hedges to mitigate the risk of variability in cash flows from oil and natural
gas sales due to changes in market prices.

    Cash-Flow Hedges
    Our cash-flow hedges consisted of fixed-price swaps and costless collars
(purchased put options and written call options). The fixed-price swap
agreements are used to fix the prices of anticipated future oil and natural gas
production. The costless collars are used to establish floor and ceiling prices
on anticipated future oil and natural gas production. There were no net premiums
received when we entered into these option agreements.

    Derivatives Not Designated as Hedges
    Our derivative positions included option contracts that are not designated
as hedges. These positions were entered into to offset the cost of other option
positions that are designated as hedges.



    The following table summarizes our commodity related derivative contracts
outstanding at November 2, 2005. The volumes and prices reflected in the table
represent average daily contract amounts for the quarterly periods presented and
the corresponding NYMEX reference price.
