The results for the six months ended 30 June 2000 and the year ended 31
December 2000 have been restated for the effects of applying FRS 19 'Deferred
Tax' (note 1).

The results for the six months ended 30 June 2000 include an exceptional charge
in costs of sales, relating to a ceiling test write-down of £42.9 million. For
the year ended 31 December 2000, the exceptional charge was £40.2 million (note
3).

All items dealt with in arising at operating profit relate to continuing
operations.

financial statements

The prior year adjustment arises from the implementation during the period of
the revised accounting policy for deferred tax provisions (note 1).

The unrealised currency translation differences shown above are the net result
of retranslating to sterling, in accordance with our accounting policy, of
significant overseas investments and certain net foreign currency borrowings
which provide a partial hedge against the impact of currency movements on those
investments.

Notes

1. Accounting policies

The interim accounts have been prepared using the same policies as those
adopted in the accounts for the financial year ended 31 December 2000, other
than where changes were necessary to implement FRS 18 'Accounting Policies' and
FRS 19 'Deferred Tax', and are unaudited. The financial information for the
year ended 31 December 2000 is an abridged version of the accounts, as adjusted
for the restatement due to a change in accounting policy (described below).
Those accounts have been reported on by the company's auditors and delivered to
the Registrar of Companies. The report of the auditors was unqualified and did
not contain a statement under section 237(2) or (3) of the Companies Act 1985.

During the period, the group adopted FRS 18 'Accounting Policies' and FRS 19
'Deferred Tax'. There was no effect on the group's net assets and results for
the period arising from the adoption of FRS 18.

Implementation of FRS 19 'Deferred Tax'

The standard, which affects the way the group accounts for deferred tax, has
been adopted by the group for the first time in these accounts. Comparative
amounts have been restated as appropriate.

FRS 19 requires the full, rather than partial, provision of future corporate
tax liabilities, and has resulted in a prior year adjustment which has
decreased shareholders' funds and increased provisions of the group by £259.8
million at 1 January 2000. In adopting FRS 19 the group has decided not to use
the option of discounting, as allowed by the standard. Comparative amounts have
been restated and consequently reserves have decreased and provisions increased
by £47.3 million for the six months ended 30 June 2000 and £94.9 million for
the year ended 31 December 2000. The tax charges for the six months ended 30
June 2000 and for the year ended 31 December 2000 have increased by £34.3
million and £81.4 million respectively.

(i) The depreciation charge for the six months ended 30 June 2001 includes a
credit of £5.4 million arising from the application of ceiling tests to the
Siri field in Denmark. This resulted in a deferred tax charge of £1.6 million.

(ii) The exceptional charge for depreciation for the six months ended 30 June
2000 of £42.9 million arose from a reduction in the estimated reserves of the
Garden Banks 161 field in the US Gulf of Mexico. For the full year ended 31
December 2000 the exceptional charge was £40.2 million. There was no related
taxation.

6. Earnings per share

The calculation of basic earnings per share is based upon the profit
attributable to ordinary shareholders for the six months ended 30 June 2001 of
£203.9 million (six months ended 30 June 2000: £157.7 million and year ended 31
December 2000: £399.6 million) and the adjusted weighted average number of
ordinary shares outstanding during the period of 482.1 million ordinary shares
(six months ended 30 June 2000: 488.5 million and year ended 31 December 2000:
487.5 million). Profit attributable to ordinary shareholders is arrived at by
deducting preference share dividends from profit on ordinary activities after
taxation. The weighted average number of ordinary shares outstanding excludes
14.7 million shares (six months ended 30 June 2000: 9.8 million and year ended
31 December 2000: 11.1 million) held by employee share scheme trusts on which
no dividend is payable.

Diluted earnings per share differs from basic earnings per share in that the
weighted average number of ordinary shares includes potential shares, being any
financial instrument or right that may entitle its holder to ordinary shares,
such as share options. The weighted number of ordinary shares used to calculate
diluted earnings per share is 490.9 million for the six months ended 30 June
2001 (six months ended 30 June 2000: 492.2 million and year ended 31 December
2000: 493.0 million).

Adjusted earnings per share differs from basic earnings per share in that the
profit attributable to ordinary shareholders for the year ended 31 December
2000 and the six months ended 30 June 2000 excludes an exceptional item (note
3). This measure, when compared to prior periods, more accurately reflects the
ongoing group performance.

During the six months ended 30 June 2001 the group commenced a share repurchase
programme. At 30 June 2001, 6.7 million ordinary shares of 25p each had been
purchased and cancelled. The repurchase prices ranged from 548.8p to 618.76p,
resulting in £38.4 million being returned to shareholders.

Notes:

(i) As at 30 June 2001 interest capitalised as part of tangible fixed assets
was £248.5 million (31 December 2000: £234.4 million and 30 June 2000: £228.5
million).

(ii) In June 2000 the group agreed to acquire all of Reading and Bates Falcon
Corporation's exploration and production assets in the US Gulf of Mexico. The
consideration for this deal of approximately £84.1 million resulted in
additions to development assets of £88.6 million including an increase in
decommissioning provisions of £4.5 million.

10. Contingencies

A third party is claiming damages in the English courts against a company
acting on behalf of a joint venture including the company, and in the Texas
courts against the company and its co-venturers, in respect of the termination
of a rig hire contract. The English court action started in January 2001 and is
now substantially complete. Final oral submissions will be made at the
beginning of October and the decision is expected in late 2001. It is difficult
to foresee with any certainty the outcome of the case or the amount of the
group's contingent liability, if any, and no provision has been made. Were the
third party to succeed in the English Court it is estimated that the maximum
liability to the group would not be material. The litigation in the Texas
courts is unlikely to commence until late 2001 and the group has been advised
that this litigation is unlikely to succeed. The company and its co-venturers
are defending the litigation vigorously.



Independent Review Report

by KPMG Audit Plc to Enterprise Oil plc

We have been instructed by the company to review the interim financial
information for the six months ended 30 June 2001 set out on pages 16 to 24
and we have read the other information contained in the interim report and
considered whether it contains any apparent misstatements or material
inconsistencies with the financial information.

Directors' responsibilities

The interim report, including the financial information contained therein, is
the responsibility of, and has been approved by, the directors. The directors
are responsible for preparing the interim report in accordance with the
Listing Rules of the Financial Services Authority which require that the
accounting policies and presentation applied to the interim figures should be
consistent with those applied in preparing the preceding annual accounts
except where any changes, and the reason for them, are disclosed.

Review work performed

We conducted our review in accordance with guidance contained in Bulletin 1999
/4 issued by the Auditing Practices Board for use in the United Kingdom. A
review consists principally of making enquiries of management and applying
analytical procedures to the financial information and underlying financial
data and based thereon, assessing whether the accounting policies and
presentation have been consistently applied unless otherwise disclosed. A
review excludes audit procedures such as tests of control and verification of
assets, liabilities and transactions. It is substantially less in scope than
an audit performed in accordance with United Kingdom Auditing Standards and
therefore provides a lower level of assurance than an audit. Accordingly, we
do not express an audit opinion on the financial information.

Review conclusion

On the basis of our review we are not aware of any material modifications that
should be made to the financial information as presented for the six months
ended 30 June 2001.

Additional Information Under US Accounting Principles

The information regarding production and financial results reported in this
statement is prepared in accordance with the group's established reporting and
accounting policies which comply with UK accounting principles.

The following supplementary information is prepared under US accounting
principles:

On January 1, 2001, the group adopted Statement of Financial Accounting
Standards (SFAS) No. 133, 'Accounting for Derivative Instruments and Certain
hedging Activities' and SFAS No. 138, 'Accounting for Certain Derivative
Instruments and Hedging Activities.' These Standards modify the criteria for
identifying derivative instruments and require that derivatives, whether in
stand-alone contracts or, in certain cases, those embedded into other
contracts, be recorded at their fair value as assets or liabilities in the
balance sheet. In addition, the Standards prescribe the accounting for the
gain or loss resulting from changes in the fair value of derivatives
designated as hedging instruments. Upon initial adoption of the Standards on
January 1, 2001, Enterprise recorded a cumulative transition loss of £5.0
million after tax into net income and £19.4 million into other comprehensive
income to reflect the fair value of derivatives intended as cash flow hedges.
In addition, £18.5 million was recorded as assets and £42.9 million was
recorded as liabilities.

Except for the historical information contained herein, this Interim Statement
includes forward-looking statements within the meaning of the Private
Securities Litigation Reform Act of 1995 that involve risks, and other risk
factors detailed from time to time in the company's publicly available
Securities and Exchange Commission reports, which could cause actual results
to be materially different.

Forward Looking Statement

This Announcement of Interim Results for the six months ended 30 June 2001
contains forward looking statements within the meaning of the Private
Securities Litigation Reform Act of 1995. These forward looking statements are
not guarantees of Enterprise's future operational or financial performance and
are subject to risks and uncertainties. The forward looking statements refer
to, among other things:

the expectation that the Skene field will start production by the end of 2001
and the Boomvang field in early 2002; the expectations for project sanction
for the Clair development and the approval of the Valhall flank plan of
development by the Norwegian authorities;

the anticipation that the group is targeting production growth of 5 per cent
over 2000 levels by 2005. Over half of this growth has been identified in the
group's existing portfolio. The balance will be achieved through exploration
success, identifying further upside potential in the group's existing
producing fields and developments and portfolio management;

the assumption the group will be able to unlock value from undeveloped
discoveries in the Petrobras portfolio using its infrastructure interests;

the expectation of increased Nelson production in 2002 due to infill drilling;
the expectation that first production from the Maclure development will occur
in the second half of 2002;

the expectation that the sale of Enterprise Oil Denmark Limited will be
completed in September 2001;

the expectation that the Tempa Rossa field will receive project sanction in
October 2001 and that the pipeline from Oil Centre to Taranto will be
commissioned in October 2001;

the expected peak production from the Boomvang field;

the expectation that the Bijupira-Salema fields will start production in the
second half 2003 and that the fields will achieve rates of up to 70,000 boepd.

Actual operational and financial results may differ materially from
Enterprise's expectations contained in the forward looking statements as a
result of various factors many of which are beyond the control of the Company.
These factors include unforeseen changes in the rate of production from
Enterprise's oil and gas fields, changes in the price of crude oil, dollar/
pound exchange rate (because, in most cases, the price of crude oil is
denominated in dollars while most of Enterprise's costs are incurred in, and
its results are reported in, pounds), adverse technical factors associated
with the exploration, development, production or transportation of
Enterprise's crude oil and natural gas reserves, changes in political or
fiscal regime in Enterprise's areas of activity, principally changes in UK,
Norwegian, Italian or US federal or state tax or similar laws or regulations,
changes in the timing of significant capital expenditures, delays in
production start-up due to an industry shortage of skilled manpower, equipment
or materials and cost inflation within the industrial sectors and economies in
which Enterprise operates.
