OVERVIEW
Diluted earnings per share from continuing operations were $0.07 in the second
quarter of 2005 compared to $0.09 in 2004.


               Diluted net earnings per share were $0.21 for the
               quarter ended June 30, 2005 compared to $0.14 in 2004.


     During the quarter, the Corporation entered into a definitive agreement to
sell its Energy Services and International Contract Drilling divisions for
approximately US$2.28 billion with the transaction expected to close on or about
September 1, 2005. The Corporation is also negotiating with a third party for
the sale of its industrial and plant maintenance business carried on by CEDA. As
a result, these businesses have been classified as discontinued operations with
continuing operations now being comprised of Canadian contract drilling, service
rig, snubbing, rentals, and related services businesses.



     With respect to the continuing businesses, the Corporation announced in
June 2005 that it was undertaking an examination of the available strategic
alternatives, including determining the viability and method of conversion to an
income trust. Although the Board of Directors has not made any decision with
respect to any specific course of action at this time, it has retained the
appropriate financial, accounting, legal and tax advisors to assist it in
identifying and assessing issues pertaining to a conversion to an income trust.
Any conversion alternatives available to Precision will be subject to review by,
and approval of the Board of Directors and will also be subject to receipt of
all required shareholder and regulatory approvals.

     As is the norm in the second quarter, weather conditions were a significant
factor affecting activity levels. An early spring break up and dry conditions in
May were boding well for a very strong second quarter. These favorable
conditions came to an abrupt halt in June as record rainfall in Alberta slowed
the movement of oilfield equipment. Dry conditions have returned in July and
activity has quickly ramped up.

     Overall the market for our services is very strong with winter pricing for
the most part being maintained through the spring and summer months. The healthy
backlog of work should give service providers pricing leverage going into the
upcoming winter season.

     With the exception of snubbing, all operating divisions reported higher
revenue for the quarter. This is particularly noteworthy in well servicing where
service rig operating hours were 10% less than prior year.

     Operating costs have escalated somewhat as a result of crew wage increases
implemented in October 2004 and increases in third party materials and labor
required for our equipment maintenance programs. Operating margins have,
however, improved year over year with operating expenses as a percentage of
revenue declining to 64.3% from 68.4% in the second quarter of 2004. This is a
strong performance for the traditionally slow second quarter. Equipment repairs
and maintenance expenditures, while substantial, are in line with our
expectations.

     At first glance, general and administrative costs appear to have increased
by over $8 million in the second quarter. While costs have increased as a result
of options granted in the last half of 2004 and additional expenses incurred in
relation to internal and external audit functions in this post Sarbanes Oxley
world, there are also a number of severance, financial advisory and legal fees
not associated with ongoing business which amounted to approximately $4 million
in the quarter.




     It is also important to note that during the six to nine month period
following the sales transactions mentioned earlier, general and administrative
expenses will be reduced as the corporate functions will be sized to match the
needs of the smaller business.

     The effective tax rate on income from continuing operations has increased
in 2005 as a result of the increased
non-deductible options expense and a tax law change in the second quarter that
was made effective January 1, 2005.

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 $185 million in the first six months of 2005. As a result the Corporation's
cash balance has increased to $307 million and the $335 million revolving bank
credit facility remains undrawn. During July 2005 the Corporation issued 244,950
shares on the exercise of stock options.

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.

                   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 $3.1 million reduction of depreciation expense for the three months
ended and a $7.9 million reduction for the six months ended June 30, 2005. Of
these amounts $1.1 million and $4.3 million relate to continuing operations for
the three and six months ended June 30, 2005, respectively.

4.   DISCONTINUED OPERATIONS

     On June 6, 2005, the Corporation entered into an agreement to dispose of
its Energy Services and International Contract Drilling divisions to Weatherford
International Ltd. for proceeds of approximately US$900 million and 26 million
common shares of Weatherford International. The transaction is expected to close
on or about September 1, 2005 and is subject to regulatory approvals and other
customary closing conditions. In addition, in the second quarter of 2005, the
Corporation adopted a formal plan to dispose of its industrial and plant
maintenance business carried on by CEDA. These dispositions are in accordance
with an extensive process undertaken by the Corporation's board of directors to
explore avenues of valuation creation for the Corporation's shareholders.

     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.




     Results of the operations of these businesses have been classified as
results of discontinued operations. The following table provides additional

5.   COMPARATIVE FIGURES

     Certain comparative figures have been reclassified to conform to the
current financial statement presentation.




                EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES


     As of the end of second quarter ended June 30, 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 second quarter ending June 30, 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.
