                                1st QUARTER 2005


OVERVIEW

Income from continuing operations for the first quarter of 2005 was $139 million
or $2.22 per diluted share, compared to $106 million or $1.88 per diluted share
for the first quarter of 2004.

            Revenue increased by 20% to $792 million, with
            operating earnings substantially surpassing this
            improvement, increasing 32% to $224 million.

         Year-over-year, Precision Drilling's three business segments increased
operating earnings with growth of 107% in Energy Services, 43% in Rental and
Production and 16% in Contract Drilling. These improvements were the result of:

o    The successful integration of the Compact(TM) wireline services and the
     internationally based land drilling rigs acquisitions executed in the
     second quarter of 2004;

o    Increased service pricing in response to continued strong demand; and

o    Enhanced equipment utilization in Energy Services.

         It is important to note that this improvement in year-over-year
profitability occurred despite decreased overall activity levels in Canada,
demonstrating the success of Precision's efforts to expand internationally, as
well as its pricing strength in the Canadian market.

         International revenue in the first quarter of 2005 increased 51% over
the same period in 2004 due to our successful acquisition of 31 internationally
based land drilling rigs and geographic expansion into high growth markets by
our Energy Services segment. Internationally, Energy Services generated higher
earnings across all product lines in nearly all of the regions in which the
company operates.

         Revenue in the Contract Drilling segment increased by 11% to $443
million in the first quarter compared to the same period in 2004. This revenue
increase was primarily driven by the acquisition of 31 internationally based
land drilling rigs in May 2004 as well as higher pricing levels in the Canadian
market. This revenue growth rate was partially reduced by lower activity levels
in Canada due to an early spring breakup, which shortened the winter drilling
season.

         Operating earnings of $171 million in the first quarter of 2005
increased 16% compared to the same period in 2004. The strong growth in
operating earnings was driven by international drilling rig fleet expansion and
pricing improvements in Canada. Further gains were limited by lower activity in
Canada and by relatively lower margins in the Eastern Hemisphere compared to
Canada. However, recent contract awards in the Eastern Hemisphere have been for
substantially increased drilling rig day rates and improved utilization is
anticipated over the coming months.

         The Canadian drilling rig fleet achieved 13,999 operating days, for an
overall utilization rate of 68% in the quarter, compared to 14,768 operating
days and a 72% utilization rate in the first quarter of 2004. The service rig
operation saw operating hours decrease by 7% year-over-year from 150,693 in the
first quarter of 2004 compared to 139,674 in the first quarter of 2005.

                                1st QUARTER 2005


         The international drilling rig fleet achieved 2,812 operating days, for
an overall utilization rate of 65% in the quarter, compared to 1,329 operating
days and a 77% utilization rate in the first quarter of 2004. The utilization
rate was reduced in the first quarter of 2005 relative to 2004 as there were 400
fewer operating days associated with the Burgos project in Mexico. The rig fleet
numbered 48 at quarter end, an increase of 29 rigs over the prior year.

         Energy Services generated revenue of $282 million in the first quarter
of 2005, an increase of 35% or $74 million over the same period in 2004. Of this
increase, $36 million related to the Compact(TM) wireline services acquisition
in May, 2004. Excluding the impact of this acquisition, the remaining $38
million of growth was achieved primarily in international operations with
Canadian revenues effectively flat year over year. In Canada, strong activity in
the first two months of the year was offset by the effects of an early spring
break up.

         Wireline Services revenue was $144 million in the first quarter of
2005, an increase of $52 million over the same period in 2004. Excluding the
impact of the Compact(TM) wireline services acquisition, revenues increased by
$16 million or 18%. Of this increase, $5 million was generated in Canada as a
result of increased activity in the first two months of the year, partially
offset by the effects of an early spring break up. The remaining $11 million
increase was driven by improved international results based on increased
activity in the United States, Mexico, Latin America, Asia Pacific and the
Middle East.

         Drilling & Evaluation Services revenue increased 25% to $100 million in
the first quarter of 2005 from $80 million in the first quarter of 2004. During
the quarter, revenues from international operations grew by $28 million, driven
by increased utilization of Precision's LWD/HEL tools and rotary steerable
systems, which together provided $14 million of incremental revenue. Offsetting
these results were the effects of an early spring break up in 2005 combined with
increased commoditization of the MWD tools in Canada.

         Revenues from Production Services grew by 20% to $36 million in the
first three months of 2005 from $30 million in the first quarter of 2004,
reflecting higher activity in Canada and the Middle East.

         Operating earnings increased by $29 million or 107% to $56 million for
the first quarter of 2005, compared to $27 million in the same period of 2004.
This increase is attributable to the Compact(TM) wireline services acquisition,
combined with revenue growth across all product lines and operating cost

improvements. Cost improvements as a percentage of revenue have occurred in the
segment's mature markets as a result of cost control initiatives, and in its
developing markets through the achievement of critical mass. Increased
depreciation, resulting from an increased tool fleet, partially offset these
gains.

(1)  SEE EXPLANATION ON PAGE 7

         The Rental and Production segment saw a 32% increase in revenue and a
43% increase in operating earnings in the first quarter of 2005 compared to the
same period in 2004. These increases were driven primarily by the industrial
plant maintenance business and its increased activity in the Alberta oil sands
projects.

OTHER ITEMS

         Corporate and other expenses remained consistent year over year with
the one exception being foreign exchange gains which amounted to $1.4 million in
the first quarter of 2005 compared to a loss of $0.3 million in 2004.

         The Corporation's effective tax rate for the first quarter of 2005 of
34.8% was also consistent with the 2004 rate of 34.3%.

         Interest expense increased in the first quarter of 2005 compared to the
same period of the prior year as a result of additional debt incurred in the
second quarter of 2004 to finance business acquisitions.

LIQUIDITY AND CAPITAL RESOURCES

         The Corporation's liquidity position continues to improve with cash
flow from operations and from the exercise of stock options exceeding net
capital spending by $56 million in the first three months of 2005. The long-term
debt to long-term debt plus equity ratio continued to decline from 0.24 at
December 31, 2004 to 0.22 at March 31, 2005 and the Corporation's $335 million
revolving bank credit facility remains undrawn. During April 2005 the
Corporation issued 30,105 shares on the exercise of stock options.

(1) OPERATING EARNINGS - NON-GAAP MEASURE

         Operating earnings is not a recognized measure under Canadian generally
accepted accounting principles (GAAP). Management believes that in addition to
net earnings, operating earnings is a useful supplemental measure as it provides
an indication of the results generated by the Corporation's principal business
activities prior to consideration of how those activities are financed or how
the results are taxed in various jurisdictions. Investors should be cautioned,
however, that operating earnings should not be construed as an alternative to
net earnings determined in accordance with GAAP as an indicator of Precision's
performance. Precision's method of calculating operating earnings may differ
from other companies and, accordingly, operating earnings may not be comparable
to measures used by other companies.

PRECISION DRILLING CORPORATION                                                10



                                1st QUARTER 2005

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


(TABULAR AMOUNTS STATED IN THOUSANDS OF DOLLARS)

1.       BASIS OF PRESENTATION

         These interim financial statements were prepared using accounting
policies and methods of their application consistent with those used in the
preparation of the Corporation's audited financial statements for the year ended
December 31, 2004, except as noted below. These interim financial statements
conform in all respects to the requirements of generally accepted accounting
principles in Canada for annual financial statements with the exception of
certain note disclosures regarding balance sheet items and transactions
occurring prior to the current reporting period. As a result, these interim
financial statements should be read in conjunction with the Corporation's
audited financial statements for the year ended December 31, 2004 contained in
the Corporation's 2004 annual report.

2.       SEASONALITY OF OPERATIONS

         The majority of the Corporation's operations are carried on in Canada.
The ability to move heavy equipment in the Canadian oil and natural gas fields
is dependent on weather conditions. As warm weather returns in the spring, the
winter's frost comes out of the ground rendering many secondary roads incapable
of supporting the weight of heavy equipment until they have thoroughly dried
out. The duration of this "spring breakup" has a direct impact on the
Corporation's activity levels. In addition, many exploration and production
areas in northern Canada are accessible only in winter months when the ground is
frozen hard enough to support equipment. The timing of freeze up and spring
breakup affects the ability to move equipment in and out of these areas. As a
result, late March through May is traditionally our slowest time.

3.       CHANGES IN ACCOUNTING ESTIMATE

         Effective January 1, 2005 Precision changed the useful life of its
drilling rigs for purposes of determining depreciation expense to 5,000
utilization days from 4,150 utilization days (3,650 operating days), and its
drill string to 1,500 from 1,100 operating days. Utilization days include both
operating and rig move days. This change in accounting estimate has been applied
prospectively and resulted in a $4.7 million reduction of depreciation expense
for the three months ended March 31, 2005.

4.      DISPOSAL OF DISCONTINUED OPERATIONS

         On February 12, 2004, the Corporation sold substantially all of the
assets of Fleet Cementers Inc. On May 7, 2004 the Corporation sold the assets of
the Polar Completions division. On August 31, 2004 the Corporation sold its 65%
interest in United Diamond Ltd. These assets were included in the Energy
Services segment and were disposed of as they were not a core component of the
Corporation's Energy Services globalization strategy.

         Results of the operations of these businesses were classified as
results of discontinued operations. The following table provides additional
information with respect to amounts included in the results of discontinued
operations for the three months ended March 31,2004:

                                1st QUARTER 2005


SHAREHOLDER INFORMATION

                EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

         As of the end of the first quarter ended March 31, 2005, an evaluation
of the effectiveness of Precision's "disclosure controls and procedures" (as
such term is defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange
Act of 1934, as amended (the "Exchange Act")) was carried out by Precision's
principal executive officer and principal financial officer. Based upon that
evaluation, the principal executive officer and principal financial officer have
concluded that as of the end of that fiscal quarter, Precision's disclosure
controls and procedures are effective to ensure that information required to be
disclosed by Precision in reports that it files or submits under the Exchange
Act is recorded, processed, summarized and reported within the time periods
specified in the Securities and Exchange Commission rules and forms.

         During the first quarter ending March 31, 2005, there were no changes
in Precision's internal control over financial reporting that have materially
affected, or are reasonably likely to materially affect, Precision's internal
control over financial reporting.

         It should be noted that while Precision's principal executive officer
and principal financial officer believe that Precision's disclosure controls and
procedures provide a reasonable level of assurance that they are effective, they
do not expect that Precision's disclosure controls and procedures or internal
control over financial reporting will prevent all errors and fraud. A control
system, no matter how well conceived or operated, can provide only reasonable,
not absolute, assurance that the objectives of the control system are met.
