Basis of Presentation	3 Months Ended
Basis of Presentation	Mar. 31, 2014
Accounting Policies [Abstract]
Basis of Presentation	1. Basis of Presentation The financial statements included in this report reflect all normal and recurring adjustments which, in the opinion of management, are necessary for a fair presentation of Hess Corporation’s (the Corporation or Hess) consolidated financial position at March 31, 2014 and December 31, 2013 and the consolidated results of operations and cash flows for the three month periods ended March 31, 2014 and 2013. The unaudited results of operations for the interim periods reported are not necessarily indicative of results to be expected for the full year. In the first quarter of 2013, the Corporation announced several initiatives to continue its transformation into a more focused pure play Exploration and Production (E&P) company. The transformation plan included fully exiting the Corporation’s Marketing and Refining (M&R) businesses, the sale of mature E&P assets, and the pursuit of monetizing Bakken midstream assets by 2015. See also Note 2, Discontinued Operations, Note 4, Dispositions and Note 16, Subsequent Events in the Notes to the Consolidated Financial Statements for a description of the divestitures included in this report. The financial statements were prepared in accordance with the requirements of the Securities and Exchange Commission (SEC) for interim reporting. As permitted under those rules, certain notes or other financial information that are normally required by U.S. generally accepted accounting principles (GAAP) have been condensed or omitted from these interim financial statements. These statements, therefore, should be read in conjunction with the consolidated financial statements and related notes included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2013. Certain information in the financial statements and notes has been reclassified to conform to the current period presentation.

Marketing expenses	$	13	$	—

Income from discontinued operations		5		21

Total facility and other exit costs	$	20	$	21

The employee severance charges primarily resulted from the Corporation’s divestiture program announced in March 2013. The severance charges were based on probable amounts incurred under ongoing severance arrangements or other statutory requirements, plus amounts earned through March 31, 2014 under enhanced benefit arrangements. The expense associated with the enhanced benefits is recognized ratably over the estimated service period required for the employee to earn the benefit upon termination.

The Corporation expects to incur additional enhanced benefit charges of approximately $25 million beyond the amounts accrued at March 31, 2014, of which $3 million relates to E&P, $10 million to Retail Marketing and Other, $8 million to Corporate and $4 million to discontinued operations. The Corporation’s estimate of employee severance costs could change due to a number of factors, including the number of employees that work through the requisite service date and the timing of when each remaining divestiture occurs.

In the first quarter of 2014, the facility and other exit costs were primarily professional fees associated with the divestitures. The facility and other exit costs in the first quarter of 2013 primarily related to the shutdown costs for Port Reading refining operations.

For the accrued employee severance at March 31, 2014 totaling $150 million, the Corporation expects to pay approximately 80% in 2014 and the remainder in 2015 and 2016. For the accrued facility and other exit costs totaling $108 million, the Corporation expects to pay approximately 35% in 2014 and the remainder in 2015 and beyond.

Business Combinations [Abstract]
Dispositions	4. Dispositions In the first quarter of 2014, the Corporation completed the sale of its interest in the Pangkah asset, offshore Indonesia for cash proceeds of approximately $650 million. This transaction resulted in a pre-tax gain of $31 million after deducting the net book value of assets, including allocated goodwill of $56 million. In addition, the Corporation sold an exploration block in Indonesia for a pre-tax loss of $20 million. In January 2014, the Corporation also announced that it had reached agreement to sell approximately 74,000 undeveloped acres in the dry gas corridor of the Utica shale for $924 million. Approximately 47,000 acres were sold in March 2014 for proceeds of approximately $590 million. There was no gain or loss as a result of this transaction as the carrying amount of undeveloped leasehold costs was reduced by the sales proceeds. See Note 16, Subsequent Events in the Notes to the Consolidated Financial Statements for dispositions occurring after March 31, 2014. In March 2013, the Corporation sold its interests in the Azeri-Chirag-Guneshli (ACG) fields (Hess 3%), offshore Azerbaijan in the Caspian Sea, and the associated Baku-Tbilisi-Ceyhan (BTC) oil transportation pipeline company (Hess 2%) for cash proceeds of $884 million. The transaction resulted in an after-tax gain of $360 million. In January 2013, the Corporation completed the sale of its interests in the Beryl fields and the Scottish Area Gas Evacuation System (SAGE) in the United Kingdom North Sea for cash proceeds of $442 million. The transaction resulted in an after-tax gain of $323 million.

Acquisition In January 2014, the Corporation’s retail marketing business acquired its partners’ 56% interest in WilcoHess, a retail gasoline joint venture, for approximately $290 million and the settlement of liabilities. Additionally, as a result of remeasuring the carrying value to fair value of its equity interest in WilcoHess in connection with the business combination, a pre-tax gain of $39 million ($24 million after income taxes) was recognized in Other, net in the Statement of Consolidated Income. Effective from the acquisition date, Hess has consolidated the results of WilcoHess. The impact of this acquisition is not material to the Corporation’s Consolidated Income Statement or Balance Sheet.

Assets Held for Sale: At March 31, 2014, the Corporation classified as held for sale its oil and gas assets in Thailand totaling $366 million, primarily comprising the net property, plant and equipment balances and allocated goodwill of $76 million. In addition, liabilities, primarily comprising asset retirement obligations and deferred income taxes totaling $193 million, were reported in Liabilities associated with assets held for sale. See Note 16, Subsequent Events in the Notes to the Consolidated Financial Statements for completion of the sale of the Corporation’s assets in Thailand.

At December 31, 2013, assets totaling $1,097 million, primarily consisting of the net property, plant and equipment balances as well as allocated goodwill of $76 million, for Thailand and the Pangkah Field, offshore Indonesia (Hess 75%) were reported as assets held for sale. In addition, liabilities related to these properties totaling $286 million, primarily consisting of asset retirement obligations and deferred income taxes, were reported in Liabilities associated with assets held for sale. In January 2014, the Corporation completed the sale of its interest in Pangkah. See Note 4, Dispositions in the Notes to the Consolidated Financial Statements.

Capitalized Exploratory Well Costs: The following table discloses the net changes in capitalized exploratory well costs pending determination of proved reserves for the three months ended March 31, 2014 (in millions):


Balance at January 1	$	2,045
Additions to capitalized exploratory well costs pending the determination of proved reserves		24

Balance at March 31, 2014	$	2,069

The preceding table excludes exploratory dry hole costs of $9 million which were incurred and subsequently expensed in 2014. Capitalized exploratory well costs greater than one year old after completion of drilling were $1,956 million at March 31, 2014. Approximately 43% of the capitalized well costs in excess of one year relates to Block WA-390-P, offshore Western Australia, where development planning and commercial activities, including negotiations with potential liquefaction partners, are ongoing. Successful negotiation with a third party liquefaction partner is necessary before the Corporation can negotiate a gas sales agreement and sanction development of the project. Approximately 26% relates to the Corporation’s Pony discovery on Block 468 in the deepwater Gulf of Mexico, and 7% relates to the Pony #3 well on Block 469. The Corporation has signed an exchange agreement with the partners of the adjacent Green Canyon Blocks 512 and 511, which contain the Knotty Head discovery. Under this agreement, Hess was appointed operator and has a 25% working interest in the blocks, which are now collectively referred to as the Stampede project. An application to unitize Blocks 468, 512, the western half of 469 and the eastern half of 511 was filed with the Bureau of Safety and Environmental Enforcement in the first quarter of 2014. Field development planning is progressing and the project is targeted for sanction in 2014. Approximately 19% relates to offshore Ghana where the Corporation has drilled seven successful exploration wells. Appraisal plans for the seven wells on the block were submitted to the Ghanaian government for approval in June 2013. Four plans have been approved and discussions continue with the government on the three remaining appraisal plans. The Corporation plans to commence a three well appraisal drilling program in the second quarter of 2014. The remainder of the capitalized well costs in excess of one year relates to projects where further drilling is planned or development planning and other assessment activities are ongoing to determine the economic and operating viability of the projects.

Guarantees and Contingencies	Mar. 31, 2014
Commitments And Contingencies Disclosure [Abstract]
Guarantees and Contingencies	13. Guarantees and Contingencies The Corporation is subject to loss contingencies with respect to various claims, lawsuits and other proceedings. The Corporation cannot predict with certainty if, how or when such claims, lawsuits and proceedings will be resolved or what the eventual relief, if any, may be. Numerous issues may need to be resolved, including through lengthy discovery, conciliation and/or arbitration proceedings, or litigation before a loss or range of loss can be reasonably estimated. Subject to the foregoing, in management’s opinion, based upon currently known facts and circumstances, the outcome of such lawsuits, claims and proceedings is not expected to have a material adverse effect on the financial condition of the Corporation. However, the Corporation could incur judgments, enter into settlements or revise its opinion regarding the outcome of certain matters, and such developments could have a material adverse effect on its results of operations in the period in which the amounts are accrued and its cash flows in the period in which the amounts are paid. The Corporation, along with many other companies engaged in refining and marketing of gasoline, has been a party to lawsuits and claims related to the use of methyl tertiary butyl ether (MTBE) in gasoline. A series of similar lawsuits, many involving water utilities or governmental entities, were filed in jurisdictions across the U.S. against producers of MTBE and petroleum refiners who produced gasoline containing MTBE, including the Corporation. The principal allegation in all cases was that gasoline containing MTBE is a defective product and that these parties are strictly liable in proportion to their share of the gasoline market for damage to groundwater resources and are required to take remedial action to ameliorate the alleged effects on the environment of releases of MTBE. In 2008, the majority of the cases against the Corporation were settled. In 2010 and 2011, additional cases were settled including an action brought in state court by the State of New Hampshire but cases brought by the State of New Jersey and the Commonwealth of Puerto Rico remained unresolved at year-end 2013. In March 2014, the Corporation agreed to settle claims against it arising out of the New Jersey action for approximately $35 million. The settlement is subject to completion of a 30 day notice and comment period and entry of the settlement by the trial judge. The Corporation has reserves to fully cover this settlement amount.

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Financial Risk Management and Trading Activities

15. Financial Risk Management and Trading Activities

In the normal course of its business, the Corporation is exposed to commodity risks related to changes in the prices of crude oil and natural gas as well as changes in interest rates and foreign currency values. Prior to the divestiture of its energy marketing business in the fourth quarter of 2014, the Corporation was also exposed to commodity risks related to changes in the prices of the refined petroleum products and electricity. In the disclosures that follow, risk management activities are referred to as corporate and energy marketing risk management activities. The Corporation also has trading operations, through a 50% voting interest in a consolidated partnership, that trades energy-related commodities, securities and derivatives. These activities are also exposed to commodity price risks primarily related to the prices of crude oil, natural gas, refined petroleum products and electricity, as well as foreign currency values.

The Corporation maintains a control environment for all of its risk management and trading activities under the direction of its chief risk officer and through its corporate risk policy, which the Corporation’s senior management has approved. Controls include volumetric, term and value at risk limits. The chief risk officer must approve the trading of new instruments and commodities. Risk limits are monitored and reported on a daily basis to business units and senior management. The Corporation’s risk management department also performs independent price verifications (IPVs) of sources of fair values and validations of valuation models. The Corporation’s treasury department is responsible for administering foreign exchange rate and interest rate hedging programs using similar controls and processes, where applicable.

The Corporation’s risk management department, in performing the IPV procedures, utilizes independent sources and valuation models that are specific to the individual contracts and pricing locations to identify positions that require adjustments to better reflect the market. This review is performed quarterly and the results are presented to the chief risk officer and senior management. The IPV process considers the reliability of the pricing services through assessing the number of available quotes, the frequency at which data is available and, where appropriate, the comparability between pricing sources.

Following is a description of the Corporation’s activities that use derivatives as part of their operations and strategies. Derivatives include both financial instruments and forward purchase and sale contracts. Gross notional amounts of both long and short positions are presented in the volume tables beginning below. These amounts include long and short positions that offset in closed positions and have not reached contractual maturity. Gross notional amounts do not quantify risk or represent assets or liabilities of the Corporation, but are used in the calculation of cash settlements under the contracts.

Corporate Financial Risk Management Activities: Corporate risk management activities include transactions designed to reduce risk in the selling prices of crude oil or natural gas produced by the Corporation or to reduce exposure to foreign currency or interest rate movements. Generally, futures, swaps or option strategies may be used to fix the forward selling price of a portion of the Corporation’s crude oil or natural gas production. Forward contracts may also be used to purchase certain currencies in which the Corporation does business with the intent of reducing exposure to foreign currency fluctuations. These forward contracts comprise various currencies, primarily the British Pound and Danish Krone. Interest rate swaps may be used to convert interest payments on certain long-term debt from fixed to floating rates.

The gross volumes of the Corporate risk management derivative contracts outstanding were as follows:


	March 31,		December 31,
	2014		2013
Commodity, primarily crude oil (millions of barrels)		8		9
Foreign exchange (millions of USD *)	$	883	$	220
Interest rate swaps (millions of USD)	$	615	$	865

*	Denominated in U.S. dollars (USD).

In the fourth quarter of 2013, the Corporation entered into Brent crude oil fixed-price swap contracts to hedge 25,000 barrels of oil per day (bopd) for calendar year 2014 and in the first quarter of 2014, an additional 5,000 bopd for the remainder of 2014, were hedged. These hedges are at an average price of $109.11 per barrel. In 2013, the Corporation had Brent crude oil fixed-price swap contracts to hedge 90,000 bopd of crude oil sales volumes at an average price of approximately $109.70 per barrel.

Crude oil price hedging contracts increased E&P Sales and other operating revenues by $3 million ($2 million after income taxes) for the three months ended March 31, 2014, and reduced E&P Sales and other operating revenues by $18 million ($11 million after income taxes) for the three months ended March 31, 2013. At March 31, 2014, the after-tax deferred gains in Accumulated other comprehensive income (loss) related to Brent crude oil hedges were $13 million, which will be reclassified into earnings during 2014 as the hedged crude oil sales are recognized in earnings. The amount of ineffectiveness from Brent crude oil hedges that was recognized immediately in Sales and other operating revenues resulted in a loss of approximately $1 million for the three months ended March 31, 2014, and a gain of $15 million for the three months ended March 31, 2013.

At March 31, 2014 and December 31, 2013, the Corporation had interest rate swaps with gross notional amounts of $615 million and $865 million, respectively, which were designated as fair value hedges. Changes in the fair value of interest rate swaps and the hedged fixed-rate debt are recorded in Interest expense in the Statement of Consolidated Income. For the three months ended March 31, 2014 and 2013, the Corporation recorded an increase of approximately $1 million and a decrease of $5 million (excluding accrued interest), respectively, in the fair value of interest rate swaps and a corresponding adjustment in the carrying value of the hedged fixed-rate debt.

Gains or losses on foreign exchange contracts that are not designated as hedges are recognized immediately in Other, net in Revenues and non-operating income in the Statement of Consolidated Income.

Net realized and unrealized pre-tax gains (losses) on derivative contracts used in Corporate Risk Management activities and not designated as hedges amounted to the following:


	Three Months Ended
	March 31,

Energy Marketing Financial Risk Management Activities: In conjunction with the sale of the energy marketing business in the fourth quarter of 2013, certain derivative contracts, including new transactions following the closing date, (the “delayed transfer derivative contracts”) were not transferred to Direct Energy, a North American subsidiary of Centrica plc (Centrica), as required customer or regulatory consents had not been obtained. However, the agreement entered into between Hess and Direct Energy on the closing date transferred all economic risks and rewards of the energy marketing business, including the ownership of the delayed transfer derivative contracts, to Direct Energy. At the end of the first quarter of 2014, a large majority of these contracts were transferred to Direct Energy. As of March 31, 2014, the assets and liabilities related to the delayed transfer derivative contracts that were not transferred remain on the Corporation’s Consolidated Balance Sheet but changes in their fair value are offset based on the terms of the agreement between Hess and Direct Energy. The Corporation therefore has no market risk related to these delayed transfer derivative contracts and only retains credit risk exposure, which has been guaranteed by Centrica. It is expected that the transfer of the remaining contracts will be substantially complete by the end of the second quarter of 2014.

Trading Activities: Trading activities are conducted through a trading partnership in which the Corporation has a 50% voting interest that is currently for sale. This partnership intends to generate earnings through various strategies primarily using energy-related commodities, securities and derivatives. The information that follows represents 100% of the trading partnership as well as the Corporation’s proprietary trading accounts for 2013.

The gross volumes of derivative contracts outstanding related to trading activities were as follows:


	March 31,		December 31,
	2014		2013
Commodity
Crude oil and refined petroleum products (millions of barrels)		1,823		1,815

Electricity (millions of megawatt hours)		1		1
Foreign exchange (millions of USD)	$	71	$	52
Equity securities (millions of shares)		19		11

Pre-tax unrealized and realized gains (losses) recorded in the Statement of Consolidated Income from trading activities amounted to the following:

*	The unrealized pre-tax gains and losses included in earnings were reflected in Sales and other operating revenues and Income from discontinued operations in the Statement of Consolidated Income.

Fair Value Measurements: The Corporation generally enters into master netting arrangements to mitigate legal and counterparty credit risk. Master netting arrangements are generally accepted overarching master contracts that govern all individual transactions with the same counterparty entity as a single legally enforceable agreement. The U.S. Bankruptcy Code provides for the enforcement of certain termination and netting rights under certain types of contracts upon the bankruptcy filing of a counterparty, commonly known as the safe harbor provisions. If a master netting arrangement provides for termination and netting upon the counterparty’s bankruptcy, these rights are generally enforceable with respect to safe harbor transactions. If these arrangements provide the right of offset and the Corporation’s intent and practice is to offset amounts in the case of such a termination, the Corporation’s policy is to record the fair value of derivative assets and liabilities on a net basis.

In the normal course of business, the Corporation relies on legal and credit risk mitigation clauses providing for adequate credit assurance as well as close-out netting, including two-party netting and single counterparty multilateral netting. As applied to the Corporation, two-party netting is the right to net amounts owing under safe harbor transactions between a single defaulting counterparty entity and a single Hess entity, and single counterparty multilateral netting is the right to net amounts owing under safe harbor transactions among a single defaulting counterparty entity and multiple Hess entities. The Corporation is reasonably assured that these netting rights would be upheld in a bankruptcy proceeding in the U.S. in which the defaulting counterparty is a debtor under the U.S. Bankruptcy Code.

The following table provides information about the effect of netting arrangements on the presentation of the Corporation’s physical and financial derivative assets and (liabilities) that are measured at fair value, with the effect of “single counterparty multilateral netting” being included in column (v):

The Corporation determines fair value in accordance with the fair value measurements accounting standard (Accounting Standards Codification 820 – Fair Value Measurements and Disclosures), which established a hierarchy that categorizes the sources of inputs, which generally range from quoted prices for identical instruments in a principal trading market (Level 1) to estimates determined using related market data (Level 3). Measurements derived indirectly from observable inputs or from quoted prices from markets that are less liquid are considered Level 2.

When Level 1 inputs are available within a particular market, those inputs are selected for determination of fair value over Level 2 or 3 inputs in the same market. To value derivatives that are characterized as Level 2 and 3, the Corporation uses observable inputs for similar instruments that are available from exchanges, pricing services or broker quotes. These observable inputs may be supplemented with other methods, including internal extrapolation or interpolation, that result in the most representative prices for instruments with similar characteristics. Multiple inputs may be used to measure fair value, however, the level of fair value for each physical derivative and financial asset or liability presented below is based on the lowest significant input level within this fair value hierarchy.

The following table provides the Corporation’s net physical derivative and financial assets and (liabilities) that are measured at fair value based on this hierarchy:

Includes a total of $61 million of Level 1, $323 million of Level 2 and $17 million of Level 3 liabilities that relate to the Corporation’s continuing operations.

(c)

Long-term debt, including current maturities, had a carrying value of $5,576 million and $5,798 million at March 31, 2014 and December 31, 2013, respectively.

In addition to the financial assets and liabilities disclosed in the tables above, the Corporation had other short-term financial instruments, primarily cash equivalents and accounts receivable and payable, for which the carrying value approximated their fair value at March 31, 2014 and December 31, 2013.

The following table provides total net transfers into and out of each level of the fair value hierarchy:

The Corporation’s policy is to recognize transfers in and transfers out as of the end of the reporting period. Transfers between levels result from the passage of time as contracts move closer to their maturities, fluctuations in the market liquidity for certain contracts and/or changes in the level of significance of fair value measurement inputs.

The following table provides changes in physical derivatives and financial assets and (liabilities) primarily related to commodities that are measured at fair value based on Level 3 inputs:

(a)

The unrealized pre-tax gains and losses included in earnings were reflected in Sales and other operating revenues and Income from discontinued operations in the Statement of Consolidated Income.

(b)

Purchases and sales primarily represent option premiums paid or received, respectively, during the reporting period and were reflected in Sales and other operating revenues and Income from discontinued operations in the Statement of Consolidated Income.

(c)

Settlements represent realized gains and losses on derivatives settled during the reporting period and were reflected in Sales and other operating revenues and Income from discontinued operations in the Statement of Consolidated Income.

The significant unobservable inputs used in Level 3 fair value measurements for the Corporation’s physical commodity contracts and derivative instruments primarily include less liquid delivered locations for physical commodity contracts or volatility assumptions for out-of-the-money options. The following table provides information about the Corporation’s significant recurring unobservable inputs used in the Level 3 fair value measurements. Natural gas contracts are usually quoted and transacted using basis pricing relative to an active pricing location (e.g. Henry Hub), for which price inputs represent the approximate value of differences in geography and local market conditions. All other price inputs in the table below represent full contract prices. Significant changes in any of the inputs, independently or correlated, may result in a different fair value.

Credit Risk: The Corporation is exposed to credit risks that may at times be concentrated with certain counterparties, groups of counterparties or customers. Accounts receivable are generated from a diverse domestic and international customer base. As of March 31, 2014, the Corporation’s net Accounts receivable – Trade related to continuing operations were concentrated with the following counterparty industry segments: Integrated Oil Companies – 29%, Refiners – 24%, Trading Companies – 21%, Financial Institutions – 15% and Government Entities – 6%. As of December 31, 2013, the Corporation’s net Accounts receivable – Trade were concentrated as follows: Integrated Oil Companies – 45%, Refiners – 18%, Financial Institutions – 14%, Government Entities – 8% and Trading Companies – 7%. The Corporation reduces its risk related to certain counterparties by using master netting arrangements and requiring collateral, generally cash or letters of credit. The Corporation records the cash collateral received or posted as an offset to the fair value of derivatives executed with the same counterparty. At March 31, 2014 and December 31, 2013, the Corporation held cash from counterparties of $62 million and $79 million, respectively. The Corporation posted cash to counterparties at March 31, 2014 and December 31, 2013, of $19 million and $168 million, respectively.

The Corporation had outstanding letters of credit totaling $389 million and $410 million at March 31, 2014 and December 31, 2013, respectively, primarily issued to satisfy margin requirements (approximately $105 million and $196 million related to discontinued operations at March 31, 2014 and December 31, 2013, respectively). Certain of the Corporation’s agreements also contain contingent collateral provisions that could require the Corporation to post additional collateral if the Corporation’s credit rating declines. As of March 31, 2014, the net liability related to both realized and unrealized derivative contracts with contingent collateral provisions was approximately $152 million ($281 million at December 31, 2013). There was $3 million cash collateral posted on those derivatives at March 31, 2014 ($31 million at December 31, 2013). At March 31, 2014 and at December 31, 2013, all three major credit rating agencies that rate the Corporation’s debt had assigned an investment grade rating. If one of the three agencies were to downgrade the Corporation’s rating to below investment grade, the Corporation would be required to post additional collateral of approximately $104 million at March 31, 2014 and $134 million at December 31, 2013.
