                Newpark Resources Reports Second Quarter Earnings

    METAIRIE, La., July 28 /PRNewswire-FirstCall/ -- Newpark Resources, Inc.
(NYSE: NR) today reported that it earned net income of $1,774,000, or $.02 per
share, on revenue of $92.4 million in the second quarter ended June 30, 2003.
This compares to a net loss of $786,000, equal to $.01 per share, on
$77.6 million in revenue in the second quarter of the prior year.

    For the six months to date, Newpark reported net income of $2,998,000, or
$0.04 per share, on revenue of $183.0 million, compared to a net loss of
$265,000 on revenue of $152.7 million in the same period of 2002.

    "While the U.S. rig count has increased by 30% since the beginning of the
year, Newpark's key Gulf Coast market has not participated in this trend and
remains below the level at which we ended fiscal 2002.  In spite of the flat
market, Newpark's operations showed a small improvement from the first quarter
levels," said James D. Cole, Newpark's Chairman and CEO.  "We believe that the
flat Gulf Coast rig count is a function of the changing risk profile of
operations in that market, driven by the challenge of increasing geologic well
depth, drilling prospect identification and the resultant higher cost of
drilling.  From review of our customers' plans going forward, we believe that
they are adapting to this change and expect increased activity beginning in
the second half of 2003," he added.

    Mat Sales, Rentals and Integrated Services

    Mat and Integrated Services produced operating income of $1.7 million on
revenue of $25.6 million in the recent quarter.  This compared to operating
income of $421,000 on revenue of $17.6 million in the year-ago period.  The
revenue increase came principally from Canadian operations and a 52%
improvement in pricing in the Gulf Coast mat rental business.  Gulf Coast mat
rental pricing averaged $0.97 per square foot in the quarter compared to
$0.64 per square foot a year ago and reflects reduced mat inventory levels
within the industry rather than a change related to market activity.  On the
strength of that pricing improvement, mat rental revenue in the Gulf Coast
increased to $6.4 million in the 2003 quarter from $4.1 million a year ago.
Composite mat sales revenues totaled $3.4 million compared to $2.0 million in
the year-ago quarter, with 1,900 units shipped in the recent period and 1,100
in the year-ago period.  "To date in 2003, composite mat sales have
contributed $7.1 million to revenue including sales of 3,500 Dura-Base(R) mats
and 4,200 Bravo(TM) Mats.  We believe that visibility of future orders is
improving and that second half results will be much improved," Cole said.

    E&P Waste

    Environmental services revenues in the recent quarter totaled
$13.5 million, contributing operating income of $3.3 million, equal to 24.1%
of revenues.  This compares to revenues of $12.2 million in the year-ago
quarter, generating $1.0 of operating income.  Year-to-date revenues increased
$3.4 million, or 15%, due primarily to higher waste volumes received from the
offshore and inland waters drilling markets.  The volume of waste per offshore
rig has continued to climb as the result of the change in regulations that
became effective late last year, reaching an annualized 17,000 barrels per rig
compared to 14,000 in the first half of 2002.  The remainder of the increase
came from an increase in market share.  For the first six months, segment
operating contribution improved to $5.9 million, or 22.0%, of revenues from
$1.6 million or 6.7% a year earlier.  "We believe that with the prospect of
some improvement in rig activity in the second half of the year, operating
margins in the unit can return to the historic 25% to 30% range," Cole
commented.

    Drilling Fluids

    Fluid sales and engineering revenue of $53.3 million in the second quarter
of 2003 generated $2.8 million of operating profit.  In the corresponding
quarter of 2002, the segment contributed $3.5 million to operating earnings on
revenues of $47.8 million.

    "In the recent quarter, we experienced a reduction in Gulf Coast market
revenue which was the primary reason for reduced operating income in the
period.  Gulf Coast market results were flat sequentially with the first
quarter and below the level achieved in 2002.  Canadian operations were down
from the first quarter level, as expected, due to the spring break-up, but
well ahead of 2002 levels on stronger drilling activity.  We expect the
Canadian market to continue to improve throughout the remainder of 2003.
Operations in the U.S. Mid-Continent region improved with rig activity,
increasing both revenue and operating contribution in the sequential quarter
and year-over-year comparisons.  Our European fluids business, acquired just
over a year ago, has made good progress, improving both revenue and operating
income during the sequential quarter.  The net improvement in non-Gulf Coast
markets, however, was not sufficient to offset the weak conditions in that key
market," Cole added.

    For the year to date, the segment revenue increased $17.4 million to
$107.2 million and produced $5.6 million in operating profit.  The May 2002
acquisition of Ava Drilling Fluids contributed $12.9 million of the increase,
with the remainder from Canada and the Mid-Continent region.  Excluding the
effect of the acquisition, revenue grew 4% year over year.

    Balance Sheet, Liquidity and Capital

    Capital expenditures in the recent quarter totaled $6.2 million with
capital spending for the remainder of the year expected to total $7 million,
keeping the total within this year's forecast depreciation total of
$22 million.  Depreciation and amortization charges totaled $5.5 million for
the quarter.  Inventory levels increased $3.2 million in the quarter,
concentrated in seasonal inventory build at Newpark's sawmill operation.
Newpark ended the quarter with $42.0 million of borrowings on its $100 million
bank credit facility, down from $46.5 million at the end of the first quarter.
Interest expense for the recent quarter was $3.9 million, while the
$1.8 million reported in the 2002 quarter was net of a $1.8 million benefit
from the settlement of an interest rate swap transaction.  At quarter-end,
long-term debt amounted to 35.8% of capital.  "We plan further debt reductions
in the second half of 2003, as we continue to work towards our 30% target
rate," Cole said.

    Outlook

    "We believe that in the first half of 2003 we have seen the bottom of the
market, and expect a slow improvement in Gulf Coast drilling activity during
the second half of the year.  Our key customers in that market are making the
transition to the heightened drilling risk profile, and we believe that the
opportunity to assist them in this effort is one for which Newpark is very
well positioned to participate with excellent incremental margins.  We expect
to see growth in the new non-oilfield opportunities within our matting segment
and increasing composite mat sale opportunities as markets strengthen.  These
factors should contribute to much-improved results in the second half of
2003," Cole said, concluding, "Finally, we are planning the formal market
introduction of the new Bravo(TM) Mat System in the fourth quarter, which
should show positive results in 2004."
