o    BP's second quarter replacement cost profit was $4,981 million compared
     with $3,873 million a year ago, an increase of 29%. For the half year,
     replacement cost profit was a record $10,472 million compared with
     $8,137 million, up 29%.

o    The second quarter result includes a net non-operating charge of
     $826 millon compared with a net non-operating charge of $198 million in
     the second quarter of 2004, and a net non-operating gain of
     $535 million in the first quarter of 2005. For the half year, the net
     non-operating charge was $291 million compared with a net gain of
     $578 million for the first half of 2004.

o    The second quarter trading environment was generally stronger than a
     year ago with higher oil and gas realizations, higher refining and
     chemicals margins, but with lower retail marketing margins.

o    Net cash provided by operating activities for the quarter and half year
     was $6.7 billion and $16.1 billion, respectively, compared with
     $5.2 billion and $12.2 billion a year ago.

o    The ratio of net debt to net debt plus equity was 18% compared with 20%
     a year ago.

o    The quarterly dividend, to be paid in September, is 8.925 cents per
     share ($0.5355 per ADS) compared with 7.10 cents per share a year ago.
     For the half year, the dividend showed an increase of 26%. In sterling
     terms, the quarterly dividend is 5.119 pence per share, compared with
     3.860 pence per share a year ago; for the half year the increase was
     25%. During the first half, the company repurchased 396 million of its
     own shares at a cost of $4.1 billion.


BP Group Chief Executive, Lord Browne, said:

     "Our record first half financial results could not have been delivered
     without the significant investments made over the last decade. These
     are capturing the benefit of the strong trading environment. Discipline
     in returning capital to shareholders after continuing to invest for the
     future is allowing us to reduce the number of shares outstanding,
     further improving per share performance."

* Profit attributable to BP shareholders.



                      Summary Quarterly Results


Exploration and Production's second quarter result was up 38% on a year ago
reflecting higher realizations in both liquids and gas and higher volumes,
partially offset by higher operating costs and revenue investments.

The Refining and Marketing result reflects improved refining margins, lower
retail marketing margins and a higher net charge for non-operating items
compared with a year ago.

In Gas, Power and Renewables the result decreased compared with a year ago due
to lower contributions from the gas marketing and natural gas liquids
businesses.

Interest and Other finance expense was $162 million for the quarter compared
with $201 million in the previous quarter. The decrease relates primarily to the
absence in the second quarter of costs associated with the early redemption of
finance leases in the first quarter of 2005.

The effective tax rate on replacement cost profit was 31.5%.

Capital expenditure was $3.3 billion for the quarter. There were no acquisitions
in the quarter. Disposal proceeds were $0.4 billion.

Net debt at the end of the quarter was $17.9 billion. The ratio of net debt to
net debt plus equity was 18%, and was also 18% at the end of the first quarter.

During the second quarter, the company repurchased 203 million of its own
shares, at a cost of $2.1 billion. These shares are held in treasury.

(a)  Replacement cost profit reflects the current cost of supplies. The
     replacement cost profit for the period is arrived at by excluding from
     profit inventory holding gains and losses. BP uses this measure to
     assist investors to assess BP's performance from period to period.
     Replacement cost profit is not a recognized GAAP measure. Operating
     cash flow is calculated from the starting point of profit before
     taxation which includes inventory holding gains and losses. Operating
     cash flow also reflects working capital movements including
     inventories, trade and other receivables and trade and other payables.
     The carrying value of these working capital items will change for
     various reasons, including movements in oil, gas and products prices.

                        Exploration and Production

The replacement cost profit before interest and tax for the second quarter was
$5,903 million, an increase of 38% over the second quarter of 2004. This result
benefited from higher realizations in both liquids and gas and higher volumes,
partially offset by higher operating costs and revenue investments. Net
non-operating losses for the second quarter total $652 million, primarily
arising from fair value losses on embedded derivatives relating to North Sea gas
contracts. The corresponding quarter in 2004 contained charges for impairment of
$160 million and losses on sales of assets of $114 million.

Production for the quarter at 4,112 mboe/d was over 3.5% higher than the second
quarter of 2004. This reflects production growth from major projects in the new
profit centres and TNK-BP, partly offset by anticipated decline in existing
profit centres.

The replacement cost profit before interest and tax of $12,389 million for the
half year was a record and represented an increase of 46% over the same period
of the previous year. This result also benefited from higher realizations and
volumes partially offset by higher operating costs and revenue investments. The
half year result included net gains on sales of assets of $1,067 million, fair
value losses of $834 million on embedded derivatives and charges for impairments
of $130 million.

In the deepwater Gulf of Mexico, efforts continue in response to the Thunder
Horse platform incident. The facility is now stable and trim; freeboard and
displacement are normal. Work continues to determine the cause. We will not
begin production, originally scheduled for end-2005, until any damage has been
identified and repaired. Elsewhere, projects in the New Profit Centres remain on
track. In Azerbaijan, line-fill of the Baku-Tbilisi-Ceyhan (BTC) oil export
pipeline commenced and the official inauguration ceremony was held on 25 May
2005. In Angola, the Kizomba B development achieved first oil in early July,
ahead of schedule. In Trinidad, both the Cannonball project and the Atlantic LNG
Train 4 remain on course for start-up of production in the second half of the
year. In addition, we approved our investment in a fifth LNG train in the North
West Shelf development in Australia during the second quarter.

Projects in the Existing Profit Centres also remain on track. In Egypt, we
extended two concessions in the Gulf of Suez: the Merged Concession Agreement
(MCA) and South Garib, which will extend the life of the existing oil fields,
increase the recovery of remaining reserves and provide a foundation for growth
through future exploration.

During the quarter, BP Trinidad and Tobago LLC (BP 70%) reached agreement for
the sale of the Teak, Samaan and Poui fields in Trinidad. Completion of the
transaction is expected in the fourth quarter of 2005 subject to regulatory and
other approvals.

(a)  Includes profit after interest and tax of equity-accounted entities.

(b)  Refinery throughputs exclude the Grangemouth and Lavera refineries
     which were transferred to Other businesses and corporate effective
     1 January 2005.

(c)  The Global Indicator Refining Margin (GIM) is the average of six
     regional indicator margins weighted for BP's crude refining capacity in
     each region. Each regional indicator margin is based on a single
     representative crude with product yields characteristic of the typical
     level of upgrading complexity. The regional indicator margins may not
     be representative of the margins achieved by BP in any period because
     of BP's particular refinery configurations and crude and product slate.
     The GIM data shown above excludes the Grangemouth and Lavera
     refineries.

                         Refining and Marketing


The replacement cost profit before interest and tax for the second quarter and
half year was $1,286 million and $2,707 million respectively. This compares with
$1,665 million and $2,585 million respectively, for the equivalent periods in
2004.

The quarter's result includes a net charge of $658 million for non-operating
items. Of this, $700 million is in respect of all fatality and personal injury
compensation claims associated with the incident at the Texas City refinery on
23 March 2005. Non-operating items also include a gain of $75 million on the
disposal of retail assets and a charge of $33 million for the impairment of an
equity-accounted entity.  The total charge for non-operating items for the half
year amounted to $685 million.

The second quarter and half year results, compared with the prior year, reflect
improved refining margins, lower retail marketing margins and a higher net
charge for non-operating items. The average refining Global Indicator Margin
(GIM) for both the second quarter and the first half of 2005 were higher than in
the equivalent periods of 2004 due to product demand strength and the benefits
of heavy/sour crude discounts. The margin realized by BP's refinery system also
reflected the benefits of locational advantages and supply optimization. Retail
marketing margins were lower than last year for both the quarter and half year
as a result of rises in crude and product prices being faster than the increase
in selling prices.

Refining crude oil throughputs for the quarter and first half were 2,536 kb/d
and 2,523 kb/d respectively, lower than last year primarily due to the impact of
disposals. The quarter's refining availability reduced to 93% compared with the
95% we achieved consistently last year and in the first quarter. This reflects
the full quarter impact of the Texas City incident. Marketing sales were 3,962
kb/d in the second quarter and 3,946 kb/d for the half year. The sales were held
at similar levels to both the second quarter and first half of 2004 despite the
significant increase in crude and product prices.

The replacement cost profit before interest and tax for the second quarter and
half year was $174 million and $578 million respectively, compared with $189
million and $390 million a year ago.

The second quarter result is lower than the same period in 2004 due to lower
contributions from the gas marketing and natural gas liquids businesses. The
first half result is higher than the same period in 2004 reflecting higher gains
from non-operating items and a similar contribution from the operating
businesses. Results reflect changes to fair value accounting following the
introduction of IFRS in 2005 which have created increased volatility in the Gas,
Power and Renewables result, negatively impacting the second quarter and half
year.

Non-operating items in the second quarter include a gain on disposal of an NGL
plant in the US and net fair value gains on embedded derivatives.

In June, BP announced plans for the world's first industrial scale project to
generate electricity from hydrogen while reducing CO2 emissions and enhancing
oil recovery in the North Sea.

Other businesses and corporate comprises Olefins and Derivatives, Finance, the
group's aluminium asset, interest income and costs relating to corporate
activities. The group's interests in PetroChina and Sinopec were divested in
early 2004. The second quarter's result includes a net gain of $17 million in
respect of non-operating items. This includes a charge in respect of the
separation of the Olefins and Derivatives business. The Olefins and Derivatives
result showed a marked increase over a year ago primarily as a result of higher
margins and volumes.

BP today announced a dividend of 8.925 cents per ordinary share to be paid in
September. Holders of ordinary shares will receive 5.119 pence per share and
holders of American Depository Receipts (ADRs) $0.5355 per ADS share. The
dividend is payable on 6 September to shareholders on the register on 12 August.
Participants in the Dividend Reinvestment Plan (DRIP) or the DRIP facility in
the US Direct Access Plan will receive the dividend in the form of shares, also
on 6 September.


                                Outlook

BP Group Chief Executive, Lord Browne, concluded:

   "First half world economic growth has been sustained near its 10-year
   average of 3%, and is expected to remain so for the rest of 2005.

   "Oil prices averaged $51.63 per barrel (Dated Brent) in the second
   quarter, around $4.00 per barrel higher than in the first quarter. OECD
   commercial inventories have risen at above normal seasonal rates in the
   second quarter and remain above five-year average levels. Prices remain
   supported by strong world oil consumption growth and limited spare oil
   production capacity.

   "US natural gas prices averaged $6.74/mmbtu (Henry Hub first of month
   index) in the second quarter, up by around $0.50/mmbtu versus the first
   quarter.  Gas inventories remain above year-earlier and five-year average
   levels but the surplus has been declining and the futures market
   continues to signal a supply-constrained market heading into the winter
   heating season.

   "BP's average refining Global Indicator Margin improved by nearly
   $2.50/bbl versus the first quarter to reach $8.42/bbl. So far in the
   third quarter, refining margins remain very firm in all regions, albeit
   below second quarter levels. The outlook for retail margins remains
   uncertain with continuing crude and product price volatility. Rising
   product prices have dampened margins over the past few weeks and have
   contributed to a weak start to the third quarter.

   "Our strategy is unchanged. We continue to execute it with discipline and
   focus. Our ability to capture the benefit of current prices and margin
   strength underpins continued dividend growth and further increases in
   share buybacks which we expect to be at least $6 billion in the second
   half of 2005 subject to market conditions and constraints. Capital
   expenditure is expected to be around $14.5 billion for the year and
   around $15 billion in 2006."

                                     Notes


1.  Transition to International Financial Reporting Standards

    For all periods up to and including the year ended 31 December 2004, BP
    prepared its financial statements in accordance with UK generally
    accepted accounting practice (UK GAAP).  From 1 January 2005 BP is
    required to prepare consolidated financial statements in accordance with
    International Financial Reporting Standards (IFRS) as endorsed by the
    European Commission ('EC').  Consequently, financial information for
    interim quarters of 2005 must be prepared on the basis of IFRS.

    The general principle that should be applied on first-time adoption of
    IFRS is that standards in force at the first reporting date (that is,
    for BP, 31 December 2005) should be applied retrospectively.  However,
    IFRS 1 'First-time Adoption of International Financial Reporting
    Standards' contains a number of exemptions which companies are permitted
    to apply. BP has elected:

    -  not to present comparative information in accordance with IAS 32
       'Financial Instruments: Disclosure and Presentation' and IAS 39
       'Financial Instruments: Recognition and Measurement'.

    -  not to restate its financial information for acquisitions occurring
       before 1 January 2003.

    -  to deem cumulative translation differences to be zero at 1 January
       2003.

    -  to recognize all actuarial gains and losses on pensions and other
       post-retirement benefits directly in shareholders' equity at 1
       January 2003.  This is consistent with the group's adoption of FRS 17
       'Retirement Benefits' in 2004.

    -  to apply IFRS 2 'Share-based Payment' retrospectively to all share-
       based payments.


    As a result of the above exemptions certain changes apply from 1 January
    2003 (BP's Date of Transition) followed by further changes (due to IAS
    32 and IAS 39) to apply from 1 January 2005.

    The quarterly information for 2005 and the restatement of financial
    information for the year ended 31 December 2004 and the interim quarters
    of 2004 have been prepared on the basis of all International Financial
    Reporting Standards (IFRSs) (with the exception of IAS 32 and IAS 39 (as
    amended) for the 2004 information) and Standing Interpretations
    Committee (SIC) and International Financial Reporting Interpretations
    Committee (IFRIC) interpretations issued by the International Accounting
    Standards Board (IASB) expected to be in effect for the year ending 31
    December 2005. It is possible that there will be changes to these
    standards and interpretations before the end of 2005, which might
    require further adjustments to this information before it is included in
    the 2005 Annual Report and Accounts.  In addition, BP has decided to
    early adopt IFRS 5 'Non-current Assets Held for Sale and Discontinued
    Operations', IFRS 6 'Exploration for and Evaluation of Mineral
    Resources', the amendment to IAS 19 'Amendment to international
    accounting standard IAS 19 Employee Benefits: Actuarial Gains and
    Losses, Group Plans and Disclosures', the amendment to IAS 39 'Financial
    Instruments: Recognition and Measurement - Cash Flow Hedge Accounting of
    Forecast Intra-group Transactions' and IFRIC 4 'Determining whether an
    Arrangement contains a Lease'.

    In the restatement information for the year ended 31 December 2004 and
    the interim quarters of 2004 financial assets and financial liabilities
    are accounted for on the basis of UK GAAP.

    Under UK GAAP, all derivatives used for trading purposes are recognized
    on the balance sheet at fair value.  However, derivative financial
    instruments used for hedging purposes are recognized by applying either
    the accrual method or the deferral method.  Under the accrual method,
    amounts payable or receivable in respect of derivatives are recognized
    rateably in earnings over the period of the contracts.  Changes in the
    derivative's fair value are not recognized.  On the deferral method,
    gains and losses from derivatives are deferred and recognized in
    earnings or as adjustments to carrying amounts as the underlying hedged
    transaction matures or occurs.

    From 1 January 2005 for IFRS all financial assets and financial
    liabilities have to be recognized initially at fair value.  In
    subsequent periods the measurement of these financial instruments
    depends on their classification into one of the following measurement
    categories: i) financial assets or financial liabilities at-fair-value-
    through-profit-and-loss (such as those used for trading purposes, and
    all derivatives which do not qualify for hedge accounting); ii) loans
    and receivables; iii) available-for-sale financial assets (including
    certain investments held for the long term) and iv) other liabilities.

    The effect of adopting IAS 39 at 1 January 2005 is shown as a movement
    in BP shareholders' equity for 2005.

1.  Transition to International Financial Reporting Standards (continued)

    The principal differences for the group between reporting on the basis
    of UK GAAP and IFRS are as follows:

    -  ceasing to amortize goodwill.

    -  setting up deferred taxation on:

       -  acquisitions;
       -  inventory valuation differences;
       -  unremitted earnings of subsidiaries, associates and jointly
          controlled entities.

    -  expensing a greater proportion of major maintenance costs.

    -  no longer recognizing dividends proposed but not declared as a
       liability at the balance sheet date.

    -  recognizing an expense for the fair value of employee share option
       schemes rather than the intrinsic value.

    -  recording asset swaps on the basis of fair value.

    -  embedded derivatives measured at fair value.

2.  Resegmentation


    With effect from 1 January 2005 there have been the following changes to
    the business segments reported by the group.


    (a)  Our petrochemicals operations have been divided between the
         Refining and Marketing segment and Other businesses and corporate.
         The Aromatics and Acetyls businesses and the petrochemicals assets
         that are integrated with our Gelsenkirchen refinery in Germany are
         now part of Refining and Marketing.  The Olefins and Derivatives
         business is now reported within Other businesses and corporate.
         This segment has also been restated to include the legacy
         historical results of other petrochemicals assets that have been
         divested during 2004.  We have also combined our Grangemouth and
         Lavera refineries into the Olefins and Derivatives business to
         maintain current operating synergies.  These changes have been made
         in connection with the establishment of our Olefins and Derivatives
         business as a stand-alone entity within BP, with a view towards its
         divestment at a later date.

    (b)  A small US operation, the Hobbs fractionator, which supplies
         petrochemicals feedstock, has been transferred from Gas, Power and
         Renewables to Olefins and Derivatives.

    (c)  The Mardi Gras pipeline system in the Gulf of Mexico has been
         transferred from Exploration and Production to Refining and
         Marketing.

    Comparative financial and operating information is shown after
    resegmentation and the adoption of International Financial Reporting
    Standards.  Further information regarding these adjustments can be found
    at the BP investor centre www.bp.com.

(a)  Natural gas is converted to oil equivalent at 5.8 billion cubic feet = 1
     million barrels.

     TNK-BP operational and financial information has been estimated and
     includes adjustments to net income in respect of prior periods amounting to
     a credit of $14 million in 2Q 2005 and a charge of $14 million in first
     half 2005.

     As reported at first quarter 2005, various TNK-BP group companies have
     received tax notifications totalling approximately $1 billion in respect of
     2001.  Discussions between TNK-BP and the Russian Federal Tax Service (FTS)
     regarding these notifications are still ongoing. In addition, the FTS is
     currently conducting routine tax audits for 2002 and 2003, although it has
     not communicated any preliminary findings and any such findings are likely
     to be dependent on the resolution of the 2001 tax issues. In the agreements
     executed at the formation of TNK-BP, BP has extensive indemnities from its
     co-venturers in respect of pre-acquisition tax liabilities.
