o    BP's second quarter pro forma result was $3,908 million, compared with

     $3,165 million a year ago, an increase of 23%. For the half year, the

     result was $8,625 million compared with $7,213 million, up 20%.

     Replacement cost profit for the second quarter and half year was

     $3,434 million and $7,604 million respectively, compared with

     $2,536 million and $5,956 million a year ago.



o    The second quarter result includes a net exceptional and non-operating

     charge of $258 million compared with a net gain of $168 million in the

     second quarter of 2003.



o    The second quarter trading environment was generally stronger than a

     year ago, with higher oil and gas realizations and refining margins.



o    Net cash inflow for the quarter was $1.5 billion and net cash inflow

     for the half year was $5.3 billion, compared with an inflow of

     $2.4 billion and an inflow of $5.6 billion a year ago. Net cash flow

     from operating activities for the quarter and half year was

     $6.9 billion and $14.6 billion respectively, compared with $7.3 billion

     and $13.3 billion a year ago.



o    The pro forma ratio of net debt to net debt plus equity was 23% at the

     end of the quarter.



o    Return on average capital employed for the quarter and half year

     respectively, on a pro forma basis, was 19.8% and 21.9%, compared with

     18.7% and 21.2% a year ago. The cash return for the quarter was 36%

     compared with 32% a year ago, and for the half year was 34% compared

     with 35% a year ago.






o    The quarterly dividend increased from 6.75 cents per share to 7.10

     cents per share ($0.426 per ADS). This compares with 6.50 cents  per

     share a year ago. For the half year the dividend showed an increase of

     8.6%. In sterling terms, the quarterly dividend is 3.860 pence per

     share compared with 4.039 pence a year ago; for the half year the

     decrease was 4.0%. During the first half, the company repurchased for

     cancellation 380 million of its own shares, at a cost of $3.25 billion.

     The increase in the per share dividend growth rate reflects the

     reduction in the number of shares outstanding due to the share buyback

     programme. This allows the company's level of dividend payments to be

     allocated across a smaller equity base.



BP Group Chief Executive, Lord Browne, said:


     "This has been another strong performance against the backdrop of a

     robust trading environment. We are on track against our targets of

     controlled investment for growth, increasing the dividend and using

     additional free cash flow to fund a significant level of share

     buybacks. The reduction in the number of shares outstanding has allowed

     us to accelerate the per share dividend growth rate. The plans to

     prepare the Olefins and Derivatives business for disposal are on

     track."



The pro forma result has been derived from the group's reported UK GAAP
accounting information but is not in itself a recognized UK or US GAAP measure.
This financial performance information and measures derived therefrom, shown
above and elsewhere in the document, are provided in order to enable investors
to evaluate better BP's performance against that of its competitors.



(a)  Replacement cost profit for the period includes the net profit or loss

     on the sale of fixed assets and businesses or termination of

     operations.



(b)  Acquisition amortization is depreciation and amortization relating to

     the fixed asset revaluation adjustments and goodwill consequent upon

     the ARCO and Burmah Castrol acquisitions. The first quarter 2004 and

     the first half results for 2003 and 2004 include accelerated

     depreciation of the revaluation adjustment in respect of the impairment

     of former ARCO assets.


                      Summary Second Quarter Results

Exploration and Production's second quarter result was up 18% on a year ago
reflecting higher liquids and gas realizations combined with the changing
production composition primarily arising from the greater proportion of
production from Russia, offset partly by exceptional losses and non-operating
charges in the quarter. The corresponding quarter in 2003 contained exceptional
gains and non-operating credits.

The Refining and Marketing result increased 43% compared with a year ago
reflecting stronger refining margins, supported by strong US product demand
coupled with below-normal inventories and the impact of industry-wide refinery
maintenance.

The Petrochemicals result improved from the first quarter reflecting the absence
of large exceptional losses reported in the first quarter together with improved
margins.

In Gas, Power and Renewables, the result increased compared with a year ago due
to a higher contribution from the natural gas liquids business in North America.

Interest and other finance expense for the quarter was $221 million compared
with $228 million for the prior quarter.

The pro forma effective tax rate on replacement cost profit was 35.7%.

Capital expenditure was $3.2 billion for the quarter and there were no
significant acquisitions. Disposal proceeds for the quarter were $0.66 billion.

Net debt at the end of the quarter was $18.2 billion. The pro forma ratio of net
debt to net debt plus equity was 23% at the end of the quarter compared with 22%
at the end of the first quarter.

During the third quarter, shares to the value of $1.25 billion will be issued to
Alfa Group and Access-Renova (AAR) as the first instalment of the deferred
consideration for our investment in TNK-BP.

---------

The commentaries above and following are based on the pro forma replacement cost
results.

TNK-BP operational and financial information has been estimated.

The financial information for 2003 has been restated to reflect (a) the transfer
of natural gas liquids (NGLs) operations from the Exploration and Production
segment to Gas, Power and Renewables on 1 January 2004; (b) the adoption by the
group of Financial Reporting Standard No. 17 'Retirement Benefits' (FRS 17) with
effect from 1 January 2004; and (c) the adoption by the group of Urgent Issues
Task Force Abstract No. 38 'Accounting for ESOP Trusts' with effect from 1
January 2004. For further information see Note 1.

                        Exploration and Production

The pro forma replacement cost result before interest and tax for the second
quarter was $4,558 million, up 18% from the second quarter of 2003. The primary
drivers for the change are the higher realizations in both liquids and gas
combined with the changing composition of production primarily arising from the
greater proportion of production from Russia. This was partly offset by the
exceptional losses and non-operating charges in the quarter. The corresponding
quarter in 2003 contained exceptional gains and non-operating credits.

Included in the results for the quarter was a non-operating charge as a result
of impairments totalling $160 million in respect of a gas processing plant in
the USA and a field in the Gulf of Mexico Shelf.

The second quarter result also includes a charge of $87 million, reflecting an
increase in the provision for Unrealized Profit in Stock (UPIS), which removes
the upstream margin from downstream inventories. This compares with a credit of
$106 million in the equivalent quarter of last year.

Production for the quarter was up 18% from the second quarter of 2003, to 3,971
mboe/d. This reflects increased production from Russia partly offset by
divestments, lower seasonal gas takes in the North Sea, anticipated decline and
unplanned shutdowns at the Mars platform in the Gulf of Mexico and in Trinidad.

The result for the half year also benefited from higher realizations combined
with the changing composition of production primarily resulting from increased
volumes from Russia offset by the above operational items.

Projects in the New Profit Centres remain on track. In the Gulf of Mexico,
offshore installation of the Holstein and Mad Dog Spars was completed, Holstein
topsides have been installed, and the Thunder Horse platform has left the
construction yard in Korea. In Algeria, first gas sales from the In Salah gas
project have been achieved. In Azerbaijan, installation of the Central Azeri
jacket was completed. In Angola, the Kizomba A Floating Production Storage and
Offloading vessel arrived at the field location in Block 15 and hook-up to the
tension leg platform is in progress. In Trinidad the Atlas methanol plant was
brought on line. In Australia, commissioning of North West Shelf Train 4 has
commenced with first gas delivered to the plant.

Projects in Existing Profit Centres are also on track. In the UK the Clair
jacket and deck has been installed offshore. In Egypt, the first steps were
taken towards the development of a major LNG business, with agreements signed to
deliver natural gas to the Damietta plant.

In the second quarter we had a further exploration success in Angola with the
Venus discovery in offshore Block 31 and two discoveries in the Nile Delta in
Egypt, Temsah and Polaris.

During the quarter, we signed sale and purchase agreements in Indonesia for the
divestment of our interest in the Kangean Production Sharing Contract and our
participating interest in the Muriah Production Sharing Contract, in the USA for
the sale of our interest in the South Pass 60 property in the Gulf of Mexico
Shelf and Swordfish in the deepwater Gulf of Mexico. The total net exceptional
losses in respect of these transactions for the quarter were $114 million.

(a)  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.

                         Refining and Marketing

The pro forma replacement cost result before interest and tax for the second
quarter was $1,562 million. This compares with $1,093 million for the same
period last year, an increase of 43%. The result for the half year represents an
increase of $577 million (30%), at $2,503 million.

Refining margins in the second quarter were stronger for most regions than in
both the equivalent quarter a year ago and the first quarter of 2004, supported
by strong US product demand, coupled with below-normal inventories and the
impact of industry-wide planned and unplanned refinery maintenance. Compared to
the second quarter of 2003, the increase in result was less than suggested by
movements in the Global Indicator Margin (GIM), due to operational outages at
the Texas City Refinery, scheduled refinery turnarounds and higher purchased
energy costs. Marketing margins increased relative to the previous quarter,
particularly at the end of the quarter, but were below seasonal norms due to
pressure from rising crude and product prices.

The improvement relative to the first half of 2003 was attributable to the
stronger refining margins, with overall marketing margins lower due to factors
outlined above.

Refining throughputs for the quarter were 3,022 mb/d, some 7% below the second
quarter of 2003 due to the disposal of the Bayernoil refinery and the planned
turnaround at Cherry Point refinery. The throughputs were some 3% higher than
those in the previous quarter due to lower turnaround activity. The quarter's
refining availability was 95.1%. Marketing sales were 4,051 mb/d, a similar
level to both the equivalent quarter last year and the previous quarter.

During the quarter, BP continued the successful roll-out of its new Ultimate(R)
(a) generation gasoline and diesel fuels with launches in Germany and Austria.

Also in the quarter, BP announced the closure of refining operations at the ATAS
Refinery in Mersin, south eastern Turkey. The site will continue to operate as a
fuels terminal.

The quarter's exceptional charges included an additional charge associated with
the termination of the lubricants operation at the Coryton Refinery and the
closure of a terminal elsewhere in the UK.

The disposal of BP's interests in the Singapore Refining Company Private Limited
was concluded on 30 June.

Shortly after the quarter, BP and the Singapore Petroleum Company Limited (SPC)
announced that conditional agreement had been reached for SPC to purchase BP's
Retail and LPG Business in the Singapore retail network and related assets for
$70 million; the transaction completion is expected towards the end of 2004.

(a) The Chemicals Indicator Margin (CIM) is a weighted average of

    externally-based product margins. It is based on market data collected

    by Nexant in their quarterly market analyses, then weighted based on

    BP's product portfolio. It does not cover our entire portfolio of

    products, and consequently is only indicative of the margins achieved by

    BP in any particular period.



(b) Provisional. The data for the second quarter is based on two months'

    actuals and one month of provisional data.


Petrochemicals' pro forma replacement cost result before interest and tax for
the second quarter was  $208 million, up from a loss of $25 million in the first
quarter. The improvement is due to the absence of large exceptional losses in
the first quarter and improved margins. The second quarter result was a decrease
of $98 million compared with the second quarter a year ago as higher product
realizations were more than offset by adverse foreign exchange impacts, higher
energy costs and increased feedstock prices. The first half result was 59% lower
than that of a year ago, reflecting exceptional losses and lower margins.
Production of 7,171 thousand tonnes in the second quarter was 72 thousand tonnes
down on the previous quarter due to seasonal turnaround activity. First half
production was 664 thousand tonnes higher than a year ago due to new Asian PTA
capacity and higher asset utilization.

During the second quarter we signed a heads of agreement with our joint venture
partner, Sinopec (BP share 50%), to build a new 500 thousand tonnes a year
acetic acid plant in China. We signed a letter of intent to examine the
viability of expanding production at the BP Zhuhai PTA plant in China (BP share
85%) to 1,200 thousand tonnes a year. We completed the sale of our Speciality
Intermediates Business.

We have progressed with plans to consolidate the Olefins and Derivatives (O&D)
business into a stand-alone entity able to operate separately from the BP Group.
The BP Group plans to sell O&D in due course, possibly commencing the sale
through an Initial Public Offering, depending on market circumstances and
necessary approvals in the second half of 2005. We intend to retain the balance
of our petrochemicals portfolio, comprising the aromatics and acetyls business.

The pro forma replacement cost result before interest and tax for the second
quarter and half year was $216 million and $414 million respectively, compared
with $141 million and $357 million a year ago. The primary reason for these
increases is a higher contribution from the natural gas liquids business in
North America.

The half year result also benefited from higher contributions from the global
LNG and Solar businesses whilst the marketing and trading result is down due to
lower margins partly offset by higher gas sales volumes.

During the quarter, the Guangdong Dapeng LNG Company Ltd. (BP share 30%) in
China signed a series of milestone agreements relating to the Guangdong LNG
terminal and trunkline project which is due on stream in 2006. In addition,
since the quarter-end, the Tangguh LNG project in Indonesia (BP share 37.16%)
signed a sale and purchase agreement for the supply of 0.55 million tonnes per
annum for a period of 20 years to Posco, who is currently building an LNG import
terminal at Gwangyang in South Korea. BP Gas Marketing Ltd. has signed an
agreement with the Egyptian Natural Gas Holding Company to purchase LNG under a
long term contract from the Damietta LNG plant which is expected to start
commercial production in 2005.

                                Outlook


BP Group Chief Executive, Lord Browne, concluded:




   "The world economy slowed in the second quarter of 2004, although growth

   remains above historic trend levels. The pace of economic activity seems

   to be easing in the US, while specific policy actions in China have been

   put in place to slow domestic demand growth. However, the momentum in

   Japan has continued and signs of recovery are emerging within Europe.

   Continued global economic growth is expected.



   "Oil prices in the second quarter averaged $35.32 per barrel (Dated

   Brent), the highest of any quarter for more than 20 years and over 10%

   and $3 per barrel higher than in the first quarter. Prices have

   strengthened further during July to date, averaging over $37 per barrel.

   Prices have been supported by continued strong oil demand growth and

   concerns about supply disruptions. OECD commercial inventories have

   remained low relative to five year averages even though OPEC production

   has increased following the 3 June agreement to raise the OPEC-10 output

   ceiling. Oil prices should remain supported by limited spare OPEC

   production capacity and further oil demand growth.



   "US natural gas prices averaged $6/mmbtu (Henry Hub first of month index)

   in the second quarter, up $0.31/mmbtu versus the first quarter. Since the

   beginning of May spot gas prices have traded in the upper half of the

   residual fuel oil and distillate parity range. The July first of month

   price was $6.14/mmbtu, although daily spot prices have since eased below

   $6/mmbtu as confidence has grown over gas availability through the summer

   cooling period. Working gas in storage remains close to the 5 year

   average. US industrial gas demand has increased. Supply is increasing as

   imports grow both from Canada and in the form of LNG and as onshore

   domestic production rises. Summer temperatures and oil prices will be the

   keys to near term gas prices.



   "Refining margins in the second quarter strengthened sharply relative to

   the first quarter of 2004. Low product inventories, strong global oil

   demand growth and concerns about US gasoline supply were all very

   supportive. The margin gains were most pronounced in the US but Europe

   also benefited. Margins in the third quarter will be increasingly

   dependent on perceived demand for distillate. Marketing margins recovered

   late in the second quarter but remain exposed to crude and product price

   volatility.



   "Petrochemical margins in the second quarter improved versus the previous

   quarter as continued global economic growth supported demand. Further

   growth in demand is anticipated, assuming the global economy remains on

   track. Volatility of energy prices and exchange rates will continue to

   influence future margins.



   "Capital expenditure, excluding acquisitions, for the first half of 2004

   was $6.4 billion, and will be around $14 billion for the year, slightly

   above our previous forecast primarily due to the weaker US dollar.

   The share buyback programme is continuing, reducing the number of

   shares outstanding and increasing our ability to accelerate per share

   dividend growth."

         activities have been transferred from the Exploration and

         Production segment to Gas, Power and Renewables.

    (b)  New accounting standard for pensions and other post-retirement

         benefits

         With effect from 1 January 2004 BP has adopted Financial Reporting

         Standard No. 17 'Retirement Benefits' (FRS 17).  FRS 17 requires

         that financial statements reflect at fair value the assets and

         liabilities arising from an employer's retirement benefit

         obligations and any related funding.  The operating costs of

         providing retirement benefits are recognized in the period in which

         they are earned together with any related finance costs and changes

         in the value of related assets and liabilities.  This contrasts

         with Statement of Standard Accounting Practice No. 24 'Accounting

         for Pension Costs', which requires the cost of providing pensions

         to be recognized on a systematic and rational basis over the period

         during which the employer benefits from the employee's services.

         The difference between the amount charged in the income statement

         and the amount paid as contributions into the pension fund is shown

         as a prepayment or provision on the balance sheet.

    (c)  Accounting for Employee Share Ownership Plans

         With effect from 1 January 2004 BP has adopted Urgent Issues Task

         Force Abstract No. 38 'Accounting for ESOP Trusts'.  This abstract

         requires that BP shares held by the group for the purposes of

         Employee Share Ownership Plans (ESOPs) are deducted from equity on

         the balance sheet.  Such shares were previously classified as fixed

         asset investments.
