Corporate Information And Statement Of IFRS Compliance [Abstract]
Basis of preparation	Basis of preparation The interim financial information included in this report has been prepared in accordance with IAS 34 'Interim Financial Reporting'. The results for the interim periods are unaudited and, in the opinion of management, include all adjustments necessary for a fair presentation of the results for each period. All such adjustments are of a normal recurring nature. This report should be read in conjunction with the consolidated financial statements and related notes for the year ended 31 December 2018 included in BP Annual Report and Form 20-F 2018 . The directors consider it appropriate to adopt the going concern basis of accounting in preparing these interim financial statements. BP prepares its consolidated financial statements included within BP Annual Report and Form 20-F on the basis of International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB), IFRS as adopted by the European Union (EU) and in accordance with the provisions of the UK Companies Act 2006 as applicable to companies reporting under IFRS. IFRS as adopted by the EU differs in certain respects from IFRS as issued by the IASB. The differences have no impact on the group’s consolidated financial statements for the periods presented. The financial information presented herein has been prepared in accordance with the accounting policies expected to be used in preparing BP Annual Report and Form 20-F 2019 , which are the same as those used in preparing BP Annual Report and Form 20-F 2018 with the exception of the adoption of IFRS 16 'Leases' from 1 January 2019. New International Financial Reporting Standards adopted BP adopted IFRS 16 ‘Leases’, which replaced IAS 17 ‘Leases’ and IFRIC 4 ‘Determining whether an arrangement contains a lease’, with effect from 1 January 2019. Further information is included in BP Annual Report and Form 20-F 2018 - Financial statements - Note 1 Significant accounting policies, judgements, estimates and assumptions - Impact of new International Financial Reporting Standards. IFRS 16 provides a new model for lessee accounting in which the majority of leases are accounted for by the recognition on the balance sheet of a right-of-use asset and a lease liability. Agreements that convey the right to control the use of an identified asset for a period of time in exchange for consideration are accounted for as leases. A lease liability is recognized at the present value of future lease payments over the reasonably certain lease term. Variable lease payments that do not depend on an index or a rate are not included in the lease liability. The right-of-use asset is recognized at a value equivalent to the initial measurement of the lease liability adjusted for lease prepayments, lease incentives, initial direct costs and any restoration obligations. The subsequent amortization of the right-of-use asset and the interest expense related to the lease liability are recognized in the income statement over the lease term. The group recognizes the full lease liability, rather than its working interest share, for leases entered into on behalf of a joint operation if the group has the primary responsibility for making the lease payments. If the right-of-use asset is jointly controlled by the group and the other joint operators, a receivable is recognized for the share of the asset transferred to the other joint operators. BP elected to apply the modified retrospective transition approach in which the cumulative effect of initial application is recognized in opening retained earnings at the date of initial application with no restatement of comparative periods’ financial information. Comparative information in the group balance sheet and group cash flow statement has, however, been re-presented to align with current year presentation, showing lease liabilities and lease liability payments as separate line items. These were previously included within the finance debt and repayments of long-term financing line items respectively. Amounts presented in these line items for the comparative periods relate to leases accounted for as finance leases under IAS 17. IFRS 16 introduces a revised definition of a lease. As permitted by the standard, BP elected not to reassess the existing population of leases under the new definition and will only apply the new definition for the assessment of contracts entered into after the transition date. On transition the standard permits, on a lease-by-lease basis, the right-of-use asset to be measured either at an amount equal to the lease liability (as adjusted for prepaid or accrued lease payments), or on a historical basis as if the standard had always applied. BP elected to use the historical asset measurement for its more material leases and used the asset equals liability approach for the remainder of the population. BP also elected to adjust the carrying amounts of the right-of-use assets as at 1 January 2019 for onerous lease provisions that had been recognized on the group balance sheet as at 31 December 2018, rather than performing impairment tests on transition. The effect of the adoption of IFRS 16 on the group balance sheet is set out below. Note 1 . Basis of preparation (continued) Adjustment 31 December 1 January on adoption $ million 2018 2019 of IFRS 16 Non-current assets Property, plant and equipment 135,261 143,950 8,689 Trade and other receivables 1,834 2,159 325 Prepayments 1,179 849 (330 ) Deferred tax assets 3,706 3,736 30 Current assets Trade and other receivables 24,478 24,673 195 Prepayments 963 872 (91 ) Current liabilities Trade and other payables 46,265 46,209 (56 ) Accruals 4,626 4,578 (48 ) Lease liabilities 44 2,196 2,152 Finance debt 9,329 9,329 — Provisions 2,564 2,547 (17 ) Non-current liabilities Other payables 13,830 14,013 183 Accruals 575 548 (27 ) Lease liabilities 623 7,704 7,081 Finance debt 55,803 55,803 — Deferred tax liabilities 9,812 9,767 (45 ) Provisions 17,732 17,657 (75 ) Net assets 101,548 101,218 (330 ) Equity BP shareholders' equity 99,444 99,115 (329 ) Non-controlling interests 2,104 2,103 (1 ) 101,548 101,218 (330 ) The presentation and timing of recognition of charges in the income statement has changed following the adoption of IFRS 16. The operating lease expense previously reported under IAS 17, typically on a straight-line basis, has been replaced by depreciation of the right-of-use asset and interest on the lease liability. In the cash flow statement payments are now presented as financing cash flows, representing payments of principal, and as operating cash flows, representing payments of interest. Variable lease payments that do not depend on an index or rate are not included in the lease liability and will continue to be presented as operating cash flows. In prior years, operating lease payments were principally presented within cash flows from operating activities. The following table provides a reconciliation of the group’s operating lease commitments as at 31 December 2018 to the total lease liability recognized on the group balance sheet in accordance with IFRS 16 as at 1 January 2019. $ million Operating lease commitments at 31 December 2018 11,979 Leases not yet commenced (1,372 ) Leases below materiality threshold (86 ) Short-term leases (91 ) Effect of discounting (1,512 ) Impact on leases in joint operations 836 Variable lease payments (58 ) Redetermination of lease term (252 ) Other (22 ) Total additional lease liabilities recognized on adoption of IFRS 16 9,422 Finance lease obligations at 31 December 2018 667 Adjustment for finance leases in joint operations (189 ) Total lease liabilities at 1 January 2019 9,900 Note 1 .

The total adjustments to the group's lease liabilities at 1 January 2019 are reconciled as follows: $ million Total additional lease liabilities recognized on adoption of IFRS 16 9,422 Less: adjustment for finance leases in joint operations (189 ) Total adjustment to lease liabilities 9,233 Of which – current 2,152 – non-current 7,081 IFRIC agenda decision on IFRS 9 'Financial Instruments' In March 2019, the IFRS Interpretations Committee (IFRIC) issued an agenda decision on the application of IFRS 9 to the physical settlement of contracts to buy or sell a non-financial item. The agenda decision concluded that where a derivative contract is settled by the physical receipt (or delivery) of the commodity, the transaction price reported for the purchase (or sale) should include the fair value of the derivative instrument in addition to the cash payable (or receivable). BP is currently assessing the impact of the agenda decision but expects it to have no effect on reported earnings.

Non-current assets held for sale	Non-current assets held for sale On 3 June 2019 BP announced that it had agreed to sell its interests in Gulf of Suez oil concessions in Egypt to Dragon Oil. Under the terms of the agreement, Dragon Oil will purchase producing and exploration concessions and BP's interest in the Gulf of Suez Petroleum Company (GUPCO). The deal, which is subject to the Egyptian Ministry of Petroleum and Mineral Resources' approval, is expected to complete during the second half of 2019. Assets and associated liabilities relating to these concessions, which are reported in the Upstream segment, have been classified as held for sale in the group balance sheet. On 22 July, BP and Bunge announced that they will each contribute their existing Brazilian biofuel, biopower and sugar businesses into a new 50:50 joint venture. Assets and associated liabilities relating to the BP businesses will be classified as held for sale in the group’s balance sheet from 22 July. Subject to satisfaction of conditions precedent, including obtaining the necessary regulatory clearances and approval, the deal is expected to complete in the fourth quarter of 2019.

Earnings per share [abstract]
Earnings per share and shares in issue	Earnings per share and shares in issue Basic earnings per ordinary share (EpS) amounts are calculated by dividing the profit (loss) for the period attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period. During the quarter the company repurchased for cancellation 11 million ordinary shares for a total cost of $75 million , as part of the share buyback programme as announced on 31 October 2017. This brings the total number of shares repurchased in the first half to 17 million for a total cost of $125 million . The number of shares in issue is reduced when shares are repurchased. The calculation of EpS is performed separately for each discrete quarterly period, and for the year-to-date period. As a result, the sum of the discrete quarterly EpS amounts in any particular year-to-date period may not be equal to the EpS amount for the year-to-date period. For the diluted EpS calculation the weighted average number of shares outstanding during the period is adjusted for the number of shares that are potentially issuable in connection with employee share-based payment plans using the treasury stock method.

As a result of the adoption of IFRS 16 ‘Leases’, leases that were previously classified as finance leases under IAS 17 are now presented as ‘Lease liabilities’ on the group balance sheet and therefore do not form part of finance debt. Comparative information for finance debt (previously termed ‘gross debt’), net debt and gearing (previously termed 'net debt ratio') have been amended to be on a consistent basis with amounts presented for 2019. The relevant amount for finance lease liabilities that has been excluded from comparative information for the second quarter and first half 2018 is $619 million . The previously disclosed amount for finance debt for the second quarter and first half 2018 was $60,358 million .

Corporate Information And Statement Of IFRS Compliance [Abstract]
Basis of presentation	Basis of preparation The interim financial information included in this report has been prepared in accordance with IAS 34 'Interim Financial Reporting'. The results for the interim periods are unaudited and, in the opinion of management, include all adjustments necessary for a fair presentation of the results for each period. All such adjustments are of a normal recurring nature. This report should be read in conjunction with the consolidated financial statements and related notes for the year ended 31 December 2018 included in BP Annual Report and Form 20-F 2018 . The directors consider it appropriate to adopt the going concern basis of accounting in preparing these interim financial statements. BP prepares its consolidated financial statements included within BP Annual Report and Form 20-F on the basis of International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB), IFRS as adopted by the European Union (EU) and in accordance with the provisions of the UK Companies Act 2006 as applicable to companies reporting under IFRS. IFRS as adopted by the EU differs in certain respects from IFRS as issued by the IASB. The differences have no impact on the group’s consolidated financial statements for the periods presented. The financial information presented herein has been prepared in accordance with the accounting policies expected to be used in preparing BP Annual Report and Form 20-F 2019 , which are the same as those used in preparing BP Annual Report and Form 20-F 2018 with the exception of the adoption of IFRS 16 'Leases' from 1 January 2019.
New International Financial Reporting Standards adopted	New International Financial Reporting Standards adopted BP adopted IFRS 16 ‘Leases’, which replaced IAS 17 ‘Leases’ and IFRIC 4 ‘Determining whether an arrangement contains a lease’, with effect from 1 January 2019. Further information is included in BP Annual Report and Form 20-F 2018 - Financial statements - Note 1 Significant accounting policies, judgements, estimates and assumptions - Impact of new International Financial Reporting Standards. IFRS 16 provides a new model for lessee accounting in which the majority of leases are accounted for by the recognition on the balance sheet of a right-of-use asset and a lease liability. Agreements that convey the right to control the use of an identified asset for a period of time in exchange for consideration are accounted for as leases. A lease liability is recognized at the present value of future lease payments over the reasonably certain lease term. Variable lease payments that do not depend on an index or a rate are not included in the lease liability. The right-of-use asset is recognized at a value equivalent to the initial measurement of the lease liability adjusted for lease prepayments, lease incentives, initial direct costs and any restoration obligations. The subsequent amortization of the right-of-use asset and the interest expense related to the lease liability are recognized in the income statement over the lease term. The group recognizes the full lease liability, rather than its working interest share, for leases entered into on behalf of a joint operation if the group has the primary responsibility for making the lease payments. If the right-of-use asset is jointly controlled by the group and the other joint operators, a receivable is recognized for the share of the asset transferred to the other joint operators. BP elected to apply the modified retrospective transition approach in which the cumulative effect of initial application is recognized in opening retained earnings at the date of initial application with no restatement of comparative periods’ financial information. Comparative information in the group balance sheet and group cash flow statement has, however, been re-presented to align with current year presentation, showing lease liabilities and lease liability payments as separate line items. These were previously included within the finance debt and repayments of long-term financing line items respectively. Amounts presented in these line items for the comparative periods relate to leases accounted for as finance leases under IAS 17. IFRS 16 introduces a revised definition of a lease. As permitted by the standard, BP elected not to reassess the existing population of leases under the new definition and will only apply the new definition for the assessment of contracts entered into after the transition date. On transition the standard permits, on a lease-by-lease basis, the right-of-use asset to be measured either at an amount equal to the lease liability (as adjusted for prepaid or accrued lease payments), or on a historical basis as if the standard had always applied. BP elected to use the historical asset measurement for its more material leases and used the asset equals liability approach for the remainder of the population. BP also elected to adjust the carrying amounts of the right-of-use assets as at 1 January 2019 for onerous lease provisions that had been recognized on the group balance sheet as at 31 December 2018, rather than performing impairment tests on transition. The effect of the adoption of IFRS 16 on the group balance sheet is set out below. Note 1 .

The operating lease expense previously reported under IAS 17, typically on a straight-line basis, has been replaced by depreciation of the right-of-use asset and interest on the lease liability. In the cash flow statement payments are now presented as financing cash flows, representing payments of principal, and as operating cash flows, representing payments of interest. Variable lease payments that do not depend on an index or rate are not included in the lease liability and will continue to be presented as operating cash flows. In prior years, operating lease payments were principally presented within cash flows from operating activities. The following table provides a reconciliation of the group’s operating lease commitments as at 31 December 2018 to the total lease liability recognized on the group balance sheet in accordance with IFRS 16 as at 1 January 2019. $ million Operating lease commitments at 31 December 2018 11,979 Leases not yet commenced (1,372 ) Leases below materiality threshold (86 ) Short-term leases (91 ) Effect of discounting (1,512 ) Impact on leases in joint operations 836 Variable lease payments (58 ) Redetermination of lease term (252 ) Other (22 ) Total additional lease liabilities recognized on adoption of IFRS 16 9,422 Finance lease obligations at 31 December 2018 667 Adjustment for finance leases in joint operations (189 ) Total lease liabilities at 1 January 2019 9,900 Note 1 .

The agenda decision concluded that where a derivative contract is settled by the physical receipt (or delivery) of the commodity, the transaction price reported for the purchase (or sale) should include the fair value of the derivative instrument in addition to the cash payable (or receivable). BP is currently assessing the impact of the agenda decision but expects it to have no effect on reported earnings.
