Notes to Consolidated Financial Statements (Unaudited)

1. Basis of Presentation

These consolidated financial statements are unaudited; however, in the opinion of management, these statements reflect all adjustments necessary for a fair statement of the results for the periods reported. All such adjustments are of a normal recurring nature unless disclosed otherwise. These consolidated financial statements, including notes, have been prepared in accordance with the applicable rules of the Securities and Exchange Commission ("SEC") and do not include all of the information and disclosures required by accounting principles generally accepted in the United States of America for complete financial statements.

Beginning in the first quarter of 2013, we changed the presentation of our consolidated statements of income, primarily to present additional details of revenues and expenses and to classify certain expenses more consistently with our peer group of independent exploration and production companies. To effect these changes, reclassifications of previously reported amounts were made and are reflected in these consolidated financial statements. As a result of the reclassifications, general and administrative expenses for the third quarter and first ~~quarter~~nine months of 2012 increased by $3940 million and $110 million which primarily includes certain costs associated with operations support and operations management. Offsetting reductions are reflected in production, other operating and exploration expenses and taxes other than income.

These interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Marathon Oil Corporation 2012 Annual Report on Form 10-K. The results of operations for the third quarter and first ~~quarter~~nine months of of 2013 are not necessarily indicative of the results to be expected for the full year.

2. Accounting Standards

Not Yet Adopted

In June 2013, the Financial Accounting Standards Board ("FASB") ratified the Emerging Issues Task Force consensus on Issue 13-C, which requires that an unrecognized tax benefit or a portion of an unrecognized tax benefit be presented as a reduction to a deferred tax asset for an available net operating loss carryforward, a similar tax loss or tax credit carryforward. This accounting standards update is effective for us beginning in the first quarter of 2014 and should be applied prospectively to unrecognized tax benefits that exist as of the effective date. Early adoption and retrospective application are permitted. We do not expect this accounting standards update to have a significant impact on our consolidated results of operations, financial position or cash flows.

In February 2013, an accounting standards update was issued to provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date, except for obligations such as asset retirement and environmental obligations, contingencies, guarantees, income taxes and retirement benefits, which are separately addressed within United States generally accepted accounting principles ("U.S. GAAP"). An entity is required to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date as the sum of 1) the amount the entity agreed to pay on the basis of its arrangement among its co-obligors and 2) any amount the entity expects to pay on behalf of its co-obligors. Disclosure of the nature of the obligation, including how the liability arose, the relationship with other co-obligors and the terms and conditions of the arrangement is required. In addition, the total outstanding amount under the arrangement, not reduced by the effect of any amounts that may be recoverable from other entities, plus the carrying amount of any liability or receivable recognized must be disclosed. This accounting standards update is effective for us beginning in the first quarter of 2014 and should be applied retrospectively for those in-scope obligations resulting from joint and several liability arrangements that exist at the beginning of 2014. Early adoption is permitted. We ~~are currently evaluating the potential impact of~~do not expect this accounting standards update to have a significant impact on our consolidated results of operations, financial position ~~and~~or cash flows.

Recently Adopted

In February 2013, an accounting standards update was issued to improve the reporting of reclassifications out of accumulated other comprehensive income. This standard requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. This accounting standards update was effective for us beginning the first quarter of 2013 and we present the required disclosures in Note1416. Adoption of this standard did not have a significant impact on our consolidated results of operations, financial position or cash flows.

MARATHON OIL CORPORATION

Notes to Consolidated Financial Statements (Unaudited)

In December 2011, an accounting standards update designed to enhance disclosures about offsetting assets and liabilities was issued. Further clarification limiting the scope of these disclosures to derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending transactions was issued in January 2013. The disclosures are intended to enable financial statement users to evaluate the effect or potential effect of netting arrangements on an entity’s financial position. Entities are required to disclose both gross information and net information about in-scope financial instruments that are either offset in the statement of financial position or subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset. The accounting standards update was effective for us beginning the first quarter of 2013 and we include the required disclosures in Note 1214. Adoption of this standard did not have a significant impact on our consolidated results of operations, financial position or cash flows.

3. Variable Interest Entity

The owners of the Athabasca Oil Sands Project (“AOSP”), in which we hold a 20 percent undivided interest, contracted with a wholly-owned subsidiary of a publicly traded Canadian limited partnership (“Corridor Pipeline”) to provide materials transportation capabilities among the Muskeg River and Jackpine mines, the Scotford upgrader and markets in Edmonton. The contract, originally signed in 1999 by a company we acquired, allows each holder of an undivided interest in the AOSP to ship materials in accordance with its undivided interest. Costs under this contract are accrued and recorded on a monthly basis, with current liabilities of $~~2 million~~ ~~and~~ $3 million recorded at ~~March 31,~~September 30, 2013 ~~and~~ , consistent with December 31, ~~2012.~~2012. Under this agreement, the AOSP absorbs all of the operating and capital costs of the pipeline. Currently, no third-party shippers use the pipeline. Should shipments be suspended, by choice or due to force majeure, we remain responsible for the portion of the payments related to our undivided interest for all remaining periods. The contract expires in 2029; however, the shippers can extend its term perpetually. This contract qualifies as a variable interest contractual arrangement and the Corridor Pipeline qualifies as a variable interest entity (“VIE”). We hold a variable interest but are not the primary beneficiary because our shipments are only 20 percent of the total; therefore the Corridor Pipeline is not consolidated by us. Our maximum exposure to loss as a result of our involvement with this VIE is the amount we expect to pay over the contract term, which was $~~711~~707 million as of ~~March 31,~~September 30, 2013. The liability on our books related to this contract at any given time will reflect amounts due for the immediately previous month’s activity, which is substantially less than the maximum exposure over the contract term. We have not provided financial assistance to Corridor Pipeline and we do not have any guarantees of such assistance in the future.

4. Income per Common Share

Basic income per share is based on the weighted average number of common shares outstanding. Diluted income per share assumes exercise of stock options and stock appreciation rights, provided the effect is not antidilutive.

2012 - International E&P Segment

In May 2012, we reached an agreement to relinquish our operatorship of and interests in the Bone Bay and Kumawa exploration licenses in Indonesia.

The fair values of assets acquired and liabilities assumed in each of these business combinations were measured primarily using an income approach, specifically utilizing a discounted cash flow analysis. The estimated fair values were based on significant inputs not observable in the market, and therefore represent Level 3 measurements. Significant inputs included estimated reserve volumes, the expected future production profile, estimated commodity prices and assumptions regarding future operating and development costs. The discount rates used in the discounted cash flow analyses were approximately 10 percent for the both the 2013 and 2012 transactions.

2013

In July 2013, we acquired 4,800 net undeveloped acres in the core of the Eagle Ford shale in a transaction valued at $97 million, including carried interest of $23 million. The transaction was accounted for as a business combination, with the entire up-front cash consideration of $74 million allocated to property, plant and equipment at the acquisition date.

2012

We acquired approximately 20,000 net acres in the core of the Eagle Ford shale during the first nine months of 2012. The largest transaction was the acquisition of Paloma Partners II, LLC, which closed during the third quarter for cash consideration of $768 million. This transaction was accounted for as a business combination. Smaller transactions closed during the second quarter of 2012.

The following table summarizes the amounts allocated to the assets acquired and liabilities assumed for Paloma Partners II, LLC based upon their fair values at the acquisition date:

7. Segment Information

Beginning in 2013, we changed our reportable segments and revised our management reporting to better reflect the growing importance of United States unconventional resource plays to our business. All prior-year periods presented have been recast to reflect these new segments.

We have three reportable operating segments. Each of these segments is organized and managed based upon both geographic location and the nature of the products and services it offers.

North America E&P ("N.A. E&P") – explores for, produces and markets liquid hydrocarbons and natural gas in North America;

International E&P ("Int'l E&P") – explores for, produces and markets liquid hydrocarbons and natural gas outside of North America and produces and markets products manufactured from natural gas, such as liquefied natural gas ("LNG")and methanol, in Equatorial Guinea; and

Oil Sands Mining (“OSM”) – mines, extracts and transports bitumen from oil sands deposits in Alberta, Canada, and upgrades the bitumen to produce and market synthetic crude oil and vacuum gas oil.

Information regarding assets by segment is not presented because it is not reviewed by the chief operating decision maker (“CODM”). Segment income represents income from continuing operations excluding certain items not allocated to segments as discussed below, net of income taxes, attributable to the operating segments. Our corporate and operations support general and administrative costs are not allocated to the operating segments. These costs primarily consist of employment costs (including pension effects), professional services, facilities and other costs associated with corporate and operations support activities, net of associated income tax effects. Unrealized gains or losses on crude oil derivative instruments, impairments, gains or losses on ~~disposal of assets~~dispositions or other items that affect comparability (as determined by the CODM) also are not allocated to operating segments.

Differences between segment totals and our consolidated totals for income taxes and depreciation, depletion and amortization represent amounts related to corporate administrative activities and other unallocated items which are included in “Items not allocated to segments, net of income taxes” in the reconciliation below. Total capital expenditures include accruals but not corporate activities.

(a) Settlements are recognized as they occur, once it is probable that lump sum payments from a plan for a given year will exceed the plan's total service and interest cost for that year. Such settlements were recorded for our U.S. plans in the second and third quarters of 2013 and the third quarter of 2012.

During the second and third quarters of 2013 and the third quarter of 2012, we recorded the effects of partial settlements of our U.S. pension plans and we remeasured the plans' assets and liabilities as of the applicable balance sheet dates. As a result, we recognized decreases of $24 million and $163 million in actuarial losses in other comprehensive income for the three months and nine months ended September 30, 2013, and an increase of $103 million in actuarial losses, net of settlement loss, for the three months and nine months ended September 30, 2012.

During the first ~~three~~nine months of 2013, we made contributions of $950 million to our funded pension plans. We expect to make additional contributions up to an estimated $5517 million to our funded pension plans over the remainder of 2013. Current benefit payments related to unfunded pension and other postretirement benefit plans were $919 million and $412 million during the first ~~three~~nine months of 2013.

8.9. Income Taxes

The effective income tax rate is influenced by a variety of factors including the geographic sources of income and the relative magnitude of these sources of income. The provision for income taxes is allocated on a discrete, stand-alone basis to pretax segment income and to individual items not allocated to segments. The difference between the total provision and the sum of the amounts allocated to segments and to individual items not allocated to segments is ~~presented~~reported in ~~Corporate~~“Corporate and other unallocated ~~items~~items” in Note 67.

Our effective income tax rates in the first ~~three~~nine months of 2013 and 2012 were 7368 percent and 6972 percent. These rates are higher than the U.S. statutory rate of 35 percent due to earnings from foreign jurisdictions, primarily Norway and Libya, where the tax rates are in excess of the U.S. statutory rate. In Libya, where the statutory tax rate is in excess of 90 percent, sales decreased in the third quarter of 2013 due to labor strikes at the Es Sider oil terminal and there remains uncertainty around ~~sustained~~future production and sales levels. Reliable estimates of 2013 and 2012 annual ordinary income from our Libyan operations could not be made and the range of possible scenarios when including ordinary income from our Libyan operations in the worldwide annual effective tax rate calculation demonstrates significant variability. As such, for the first ~~three~~nine months of 2013 and 2012, an estimated annual effective tax ~~rate was~~rates were calculated excluding Libya and applied to consolidated ordinary income excluding Libya and the tax provision applicable to Libyan ordinary income was recorded as a discrete item in the ~~period.~~periods. Excluding Libya, the effective tax ~~rate~~rates would be 6560 percent and 64 percent for the first ~~three~~nine months of 2013 and 2012. In the third quarter of 2013, we recorded a net favorable tax adjustment of $42 million, largely related to greater expected utilization of foreign tax credits in future periods than previously estimated.

InDuring the third quarter of 2013, our Libya production operations were impacted due to labor strikes at the Es Sider oil terminal.

Commodity swaps in Level 2 are measured at fair value with a market approach using prices obtained from exchanges or pricing services, which have been corroborated with data from active markets for similar assets or liabilities. Commodity options in Level 2 are valued using ~~The~~the Black-Scholes Model. Inputs to this model include prices as noted above, discount factors, and implied market volatility. The inputs to this fair value measurement are categorized as Level 2 because predominantly all assumptions and inputs are observable in active markets throughout the term of the instruments. Collateral deposits related to commodity derivatives are in broker accounts covered by master netting agreements.

Interest rate swaps are measured at fair value with a market approach using actionable broker quotes which are Level 2 inputs. Foreign currency forwards are measured at fair value with a market approach using third-party pricing services, such as Bloomberg L.P., which have been corroborated with data from active markets for similar assets or liabilities, and are Level 2 inputs.

Fair Values - Nonrecurring

The following table shows the values of assets, by major category, measured at fair value on a nonrecurring basis in periods subsequent to their initial recognition.

Notes to Consolidated Financial Statements (Unaudited)

All long-lived assets held for use that were impaired in the first ~~quarters~~nine months of2013 and 2012 were held by our North America E&P segment. The fair values of each discussed below were measured using an income approach based upon internal estimates of future production levels, prices and discount rate, all of which are Level 3 inputs. Inputs to the fair value measurement included reserve and production estimates made by our reservoir engineers, estimated commodity prices adjusted for quality and location differentials, and forecasted operating expenses for the remaining estimated life of the reservoir.

In the first quarter of 2013, as a result of our decision to wind down operations in the Powder River Basin due to poor economics, an impairment of $15 million was recorded.

In early 2012, production rates from the Ozona development in the Gulf of Mexico declined significantly. Accordingly, our reserve engineers prepared evaluations of our future production as well as our reserves and an impairment of $261 million was recorded in the first quarter of 2012. As the development produced towards abandonment pressures, further downward revisions of reserves were taken, resulting in an additional impairment recorded in the fourth quarter of 2012. Ozona production ceased in the first quarter of 2013 and an additional $21 million impairment was recorded.

Other impairments of long-lived assets held for use by our North America E&P segment in the first ~~quarters~~nine months of2013 and 2012 were a result of reduced drilling expectations, reductions of estimated reserves or declining natural gas prices.

Fair Values – Financial Instruments

Our current assets and liabilities include financial instruments, the most significant of which are receivables, commercial paper and payables. We believe the carrying values of our receivables, commercial paper and payables approximate fair value. Our fair value assessment incorporates a variety of considerations, including (1) the short-term duration of the instruments, (2) our investment-grade credit rating, and (3) our historical incurrence of and expected future insignificance of bad debt expense, which includes an evaluation of counterparty credit risk.

^(a) Excludes capital leases.

Fair values of our financial assets included in other noncurrent assets, and of our financial liabilities included in other current liabilities and deferred credits and other liabilities are measured using an income approach and most inputs are internally generated, which results in a Level 3 classification. Estimated future cash flows are discounted using a rate deemed appropriate to obtain the fair value.

Most of our long-term debt instruments are publicly-traded. A market approach, based upon quotes from major financial institutions, is used to measure the fair value of such debt. Because these quotes cannot be independently verified to an active market they are considered Level 3 inputs. The fair value of our debt that is not publicly-traded is measured using an income approach. The future debt service payments are discounted using the rate at which we currently expect to borrow. All inputs to this calculation are Level 3.

Performance unit awards

~~During~~In the first quarter of 2013,, we granted 353,600 performance units to certain officers that provide a cash payout upon the achievement of certain performance goals at the end of a 36-month performance period. The performance goals are tied to our total shareholder return (“TSR”) as compared to TSR for a group of peer companies determined by the Compensation Committee of the Board of Directors. At the grant date, each unit represents the value of one share of our common stock, while payout after completion of the performance period will be based on the value of anywhere from zero to two times the number of units granted. Dividend equivalents accrue during the performance period and are paid in cash at the end of the performance period based on the number of shares that would represent the value of the units. The fair value of these performance units is re-measured on a quarterly basis using the Monte Carlo simulation method. These performance units are accounted for as liability awards because they are to be settled in cash at the end of the performance period and their fair value is expensed over the performance period.

~~16.~~19. Commitments and Contingencies

We are a defendant in a number of lawsuits arising in the ordinary course of business, including, but not limited to, royalty claims, contract claims and environmental claims. While the ultimate outcome and impact to us cannot be predicted with certainty, we believe the resolution of these proceedings will not have a material adverse effect on our consolidated financial position, results of operations or cash flows. Certain of these matters are discussed below.

Litigation – In March 2011, Noble Drilling (U.S.) LLC (“Noble”) filed a lawsuit against us in the District Court of Harris County, Texas, alleging, among other things, breach of contract, breach of the duty of good faith and fair dealing, and negligent misrepresentation, relating to a multi-year drilling contract for a newly constructed drilling rig to be deployed in the U.S. Gulf of Mexico. We filed an answer in April 2011, contending, among other things, failure to perform, failure to comply with material obligations, failure to mitigate alleged damages and that Noble failed to provide the rig according to the operating, performance and safety requirements specified in the drilling contract. In April 2013, we filed a counterclaim against Noble alleging, among other things, breach of contract and breach of the duty of good faith relating to the multi-year drilling contract. The counterclaim also included a breach of contract claim for reimbursement for the value of fuel used by Noble under an offshore daywork drilling contract. ~~We are vigorously defending~~The parties have reached a tentative settlement of this litigation. ~~The ultimate outcome~~We believe that the settlement of this ~~lawsuit, including any financial~~litigation will not have a material adverse effect on ~~us, remains uncertain. We do not believe an estimate~~our consolidated results of ~~a reasonably probable loss (or range of loss) can be made for this lawsuit at this time.~~operations, financial position or cash flows.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

We are an international energy company with operations in the United States, Canada, Africa, the Middle East and Europe. We have three reportable operating segments. Each of these segments is organized and managed based upon both geographic location and the nature of the products and services it offers.

North America Exploration and Production ("E&P") – explores for, produces and markets liquid hydrocarbons and natural gas in North America;

International E&P – explores for, produces and markets liquid hydrocarbons and natural gas outside of North America and produces and markets products manufactured from natural gas, such as LNG and methanol, in Equatorial Guinea; and

Oil Sands Mining – mines, extracts and transports bitumen from oil sands deposits in Alberta, Canada, and upgrades the bitumen to produce and market synthetic crude oil and vacuum gas oil.

Certain sections of this Quarterly Report on Form 10-Q, including Management’s Discussion and Analysis of Financial Condition and Results of Operations contain forward-looking statements concerning trends or events potentially affecting our business. These statements typically contain words such as “anticipates,” “believes,” “estimates,” “expects,” “targets,” “plans,” “projects,” “could,” “may,” “should,” “would” or similar words indicating that future outcomes are uncertain. In accordance with “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995, these statements are accompanied by cautionary language identifying important factors, though not necessarily all such factors, which could cause future outcomes to differ materially from those set forth in the forward-looking statements. For additional risk factors affecting our business, see Item 1A. Risk Factors in our 2012 Annual Report on Form 10-K. We assume no duty to update these statements as to any future date.

Overview and Outlook

North America E&P

Production

Net liquid hydrocarbon and natural gas sales volumes averaged ~~198~~200 thousand barrels of oil equivalent per day ("mboed") in both the third quarter and first nine months of2013 compared to 172 mboed ~~during the~~ ~~first quarter of 2013~~and ~~147~~155 mboed in the ~~same period~~third quarter and first nine months of2012, afor 35increases of approximately 16 percent ~~increase.~~and 29 percent, respectively. Net liquid hydrocarbon sales volumes ~~increased,~~increased for both the third quarter and first nine months of2013, primarily reflecting the impact of our ongoing development programs in the Eagle Ford and Bakken shale resource plays, while net natural gas sales volumes ~~decreased slightly~~decreased 19 percent and 7 percent during the same periods, primarily due to the sale of our Alaska assets in January 2013. Excluding the sales ~~volume~~volumes related to Alaska in both nine-month periods, our average net ~~liquid hydrocarbon and~~ natural gas sales volumes increased ~~47 percent.~~21 percent primarily due to the previously mentioned development programs.

Eagle Ford – In 2013, production growth continued in the Eagle Ford shale play. Average net sales volumes were 7281 mboed and 78 mboed in the third quarter and first ~~quarter~~nine months of2013 compared to 1440 mboed and 25 mboed in the same ~~period~~periods of 2012. Approximately 6463 percent of the first ~~quarter~~nine months of 2013 production was crude oil and condensate, 17 percent was natural gas liquids ("NGLs") and 1920 percent was natural gas. ~~During~~In the ~~first~~third quarter of 2013,~~, we reached total depth on 76 gross operated wells and brought 68 gross operated wells to sales. We continue to advance our drilling performance, reducing~~ the ~~average time to drill a well from 28 days in the first quarter~~amount of ~~2012 to 18 days in the first quarter of 2013. We expect these drilling times to continue dropping during 2013 as additional efficiencies are gained from pad drilling.~~

We continue to build infrastructure to support production growth across the Eagle Ford operating area. Approximately 148 miles of gathering lines were installed in the first quarter of 2013, while five new central gathering and treating facilities were commissioned, with two additional facilities in various stages of planning or construction. As of March 31, 2013, we transport approximately 65 percent of our crude oil and condensate transported by pipeline ~~with additional contract negotiations and facility designs under way that are expected to push that figure to 75 percent by the end of May.~~was approximately 70 percent. The ability to transport more barrels by pipeline enables us to reduce costs, improve reliability and lessen our environmental footprint.

~~We are confident~~During the third quarter of 2013, we reached total depth on 70 gross operated wells and brought 71 gross operated wells to sales, with 228 gross operated wells reaching total depth and 219 gross operated wells brought on line in the first nine months of 2013. With approximately 97 percent pad drilling in the third quarter of 2013, which continues to improve efficiencies and reduce costs, our ~~core~~third quarter average spud-to-total depth time was 12 days, compared to 15 days spud-to-total depth in the same period of 2012.

To support production growth across the Eagle Ford ~~acreage position will~~operating area, approximately 192 miles of gathering lines were installed in the first nine months of 2013, for a total of over 670 miles. We now have 24 central gathering and treating facilities, with one more to be ~~developed on a maximum of 80-acre spacing and~~completed in 2013.

We continue to evaluate the potential of downspacing to 40-acre and 60-acre ~~units.~~units, with the results of the downspacing pilots expected to be released in December 2013. We ~~have begun drilling wells in~~also continue to evaluate the Austin Chalk and Pearsall formations across our acreage position. To date, we have completed four Austin Chalk wells. Early Austin Chalk production results suggest that the mix of crude oil and condensate, NGLs and natural gas is similar to further test the potential of these horizons. The results to-date of the downspacing pilots have been in line with our expectations, and we anticipate releasing more definitive results of both the downspacing pilots and the additional formation testingEagle Ford condensate wells. Also in the second ~~half~~quarter of ~~2013.~~2013, one Pearsall well was completed.

Bakken – Average net sales volumes from the Bakken shale were 3738 mboed in both the third quarter and first ~~quarter~~nine months of 2013 compared to 2530 mboed and 27 mboed in the same ~~period~~periods of 2012. Our Bakken production averages approximately 90 percent crude oil, 54 percent NGLs and 56 percent natural gas. During the ~~first~~third quarter of 2013, we reached total depth on 1821 gross operated wells and brought 22the same number to sales. During the first nine months of 2013, we reached total depth on 61 gross operated wells and brought 56 gross operated wells to sales. Our third quarter average time to drill a well ~~was 25 days.~~

~~In the Oklahoma Resource Basins, net sales volumes averaged 13 mboed in the~~ ~~first quarter of 2013~~continued to improve, averaging 14 days spud-to-total depth, compared to ~~5 mboed~~18 days spud-to-total depth in the same period of 2012. ~~All net~~

During the ~~first~~third quarter of 2013, ~~four~~we reached total depth on three gross operated wells and two gross operated wells were brought to sales, while during the first nine months of 2013 we reached total depth on eight gross operated wells and brought nine gross operated wells to sales. We ~~anticipate drilling~~spud two wells ~~each~~ in the Mississippi Lime formation in central Oklahoma during October 2013 and expect to spud wells in the Granite Wash ~~formations during 2013.~~around year end.

Exploration

~~Exploration activity continues~~Gulf of Mexico – In September 2013, we began drilling our operated exploration well on the Madagascar prospect located on De Soto Canyon Block 757. We have reduced our working interest in the ~~Gulf~~Madagascar prospect from 100 percent to 40 percent as a result of ~~Mexico.~~ two farm-outs. We expect the well to reach total depth late in the fourth quarter of 2013.

We participated in an appraisal well on the Gunflint prospect located on Mississippi Canyon Block 992 in which we hold an 18 percent non-operated working interest. The appraisal well successfully encountered 109 feet of net pay within the primary reservoir targets. After penetrating the initial appraisal targets, the well was deepened to a previously untested Lower Miocene interval. Commercial hydrocarbons were not encountered in the deeper exploration objective. Additional exploration potential remains in an adjacent structure to the north, which is a candidate for future exploration following development of the confirmed resources.

The first appraisal well on the Shenandoah prospect located on Walker Ridge Block 51, in which we have a 10 percent ~~outside-operated~~non-operated working interest, reached total depth in the first quarter of 2013. ~~We are currently participating in a Gunflint prospect~~This appraisal well ~~located on Mississippi Canyon Block 992 where we hold an 18 percent non-operated working interest.~~successfully encountered more than 1,000 net feet of oil pay in multiple high-quality Lower Tertiary-aged reservoirs. Additional appraisal drilling is anticipated to begin in 2014.

In ~~March~~the second quarter of 2013, ~~we submitted the apparent high bids totaling~~at a total cost of $33 million, ~~for~~we were awarded 100 percent working interest leases in two ~~blocks in Central~~ Gulf of Mexico ~~Lease Sale 227:~~blocks: Keathley Canyon Block 340 on the Colonial prospect and Keathley Canyon Block 153, an extension to the Meteor prospect on our existing Keathley Canyon Block 196 lease. Keathley Canyon Blocks 340 and 153 are both inboard-Paleogene prospects.

Canada – During the first quarter of 2012, we submitted a regulatory application relating to our Canada in-situ assets at Birchwood, for a proposed 12 mbbld steam assisted gravity drainage ("SAGD") demonstration project. We are expecting to receive regulatory approval for this project in ~~late 2013 or early 2014.~~mid-2014. Upon receiving this approval, we will further evaluate our development plans.

In addition, the~~ ~~first quarter of 2013~~ ~~includes~~Es Sider oil terminal, for average net liquid hydrocarbon sales volumes of 16 mbbld in the third quarter of 2013 compared to 49 mbbld in the same quarter of 2012. Both the third quarter and first nine months of2013 include net liquid hydrocarbon sales volumes of 9 ~~mboed~~ mbbld from the PSVM development located on the northeastern portion of Angola Block 31 which had first sales in February 2013.

~~Strong operational performance continues in~~ Equatorial Guinea ~~with availability of nearly 98 percent~~– Average net sales volumes were 109 mboed and 105 mboed in the third quarter and first nine months of 2013 compared to 116 mboed and 106 mboed in the same periods of 2012. Third quarter 2012 sales volumes were higher than normal due to the timing of ~~2013, which bolstered production during the first quarter of 2013. We started a 30-day~~liquid hydrocarbon liftings. The planned turnaround that occurred in ~~Equatorial Guinea on~~ April 1, 2013 ~~which~~ was safely completed in 22 days, eight days ahead of schedule and below budget. ~~The Alba field, associated gas plant and liquefied natural gas facility each resumed full production on April 22, 2013.~~

~~The production decline~~Sales in the ~~Alvheim area offshore~~ second quarter of 2013 were impacted by the turnaround, but recovered in the third quarter.

Norway ~~continues~~– Average net sales volumes from Norway were 68 mboed and 81 mboed in the third quarter and first nine months of2013 compared to 89 mboed and 91 mboed in the same periods of 2012. A planned nine-day turnaround in Norway resulted in lower production and sales volumes during the third quarter of 2013, with rates returning to normal levels within the latter half of the quarter. Production declines, while present, continue to be less ~~severe~~ than ~~expected. These better-than-expected results have been achieved through continued~~expected as a result of strong operational performance ~~that delivered availability of 97~~(with unplanned downtime at less than 2 percent infor the first ~~quarter~~nine months of ~~2013, reservoir and~~2013), production optimization efforts, recent infill well performance at the upper end of expectations, ~~primarily due to~~as well as a delay in anticipated water breakthrough at the Volund field.

United Kingdom – Average net sales volumes were 24 mboed in the third quarter and first nine months of2013 compared to 22 mboed and 23 mboed in the same periods of 2012. Production at the non-operated Foinaven field was shut-in in mid-July 2013 due to compression and ~~sustained contributions from~~subsea equipment issues and resumed at partial rates in late August.

Exploration

~~In the~~ Kurdistan Region of Iraq we– We hold a 45 percent operated working ~~interests~~interest in ~~both~~ the Harir ~~and Safen blocks. Current exploratory drilling includes~~block. In October 2013, we announced the ~~Mirawa well which began in March 2013~~Mirawa-1 discovery on the Harir ~~Block~~block. The Mirawa-1 was drilled to a total depth of 14,000 feet and encountered multiple stacked oil and natural gas producing zones with equipment constrained test flow rates of more than 11 mbbld of oil, 72 million cubic feet per day ("mmcfd") of non-associated natural gas and 1,700 barrels per day of condensate. We have suspended the ~~Safen~~ well ~~which commenced~~for potential future use as a producing well, and moved the drilling rig to the Jisik-1 prospect located nine miles to the northwest to test a similar structure on the Harir Block.

Following evaluation of the Safen-1 dry well in ~~April 2013~~October, we notified the Kurdistan Ministry of Natural Resources that we do not intend to participate in any further exploration on the Safen Block. ~~Both of these wells are expected to reach projected total depth in the third quarter of 2013 with testing programs to follow on each well.~~

~~Additionally, following~~Following the successful appraisal program on the non-operated Atrush Block and a declaration of commerciality, ~~was filed with the government and~~ a plan for field development was approved by the Kurdistan Ministry of Natural Resources in late September 2013.

We hold a 15 percent working interest in the Atrush Block.

On the non-operated Sarsang block, of the two exploration wells which began drilling in the second half of 2012, tests have been completed on the Gara well. All zones were water-wet and the well was plugged and abandoned in August 2013. On the Mangesh well, five drill stem tests have been completed and further testing is planned. The East Swara Tika exploration well, which began in July 2013, has been drilled to a depth of 5,300 feet toward a planned total depth of 11,000 feet. This well will test additional resource potential to the northeast of the previously announced Swara Tika discovery. We hold a 25 percent working interest in the Sarsang ~~block.~~Block.

Ethiopia – Drilling on the Tultule prospect, approximately two miles from the Sabisa-1 well on the onshore South Omo block in a frontier rift basin, commenced in September 2013 with a projected total depth of 7,900 feet. The well is expected to reach total depth by the end of the fourth quarter of 2013. The Sabisa-1 exploration well encountered reservoir quality sands, oil and heavy gas shows and a thick shale section. The presence of oil prone source rocks, reservoir sands and good seals is encouraging for the numerous fault bounded traps identified in the ~~South Omo block onshore Ethiopia has been drilled to total depth and recorded hydrocarbon indications in sands beneath~~basin.

Oil Sands Mining

Our Oil Sands Mining operations consist of a 20 percent non-operated working interest in the Athabasca Oil Sands Project (“AOSP”). Our net synthetic crude oil sales were 5149 mbbld and 47 mbbld in the ~~first~~third quarter and first nine months of2013 compared to 4453 mbbld and 47 mbbld in the same ~~period~~periods of 2012. ~~Both~~For the first nine months of 2013, the impact of strong reliability experienced at both mines and the upgrader ~~experienced significantly improved reliability~~ during the first and third quarters of 2013, was offset by unplanned mine downtime and a planned upgrader turnaround during the second quarter of 2013. ~~Primarily because of reliability improvements, combined production from the Jack Pine and Muskeg River mines set a record bitumen production rate in the~~ ~~first~~ ~~quarter of~~ ~~2013~~. In addition, upgrader availability was 100 percent for the entire first quarter of 2013, allowing the facility to maximize production of lighter synthetic crude oils, which improved realizations and profit margins.

Acquisitions and Dispositions

In ~~April~~September 2013, we announced that we had reached an agreement in principle to sell our ~~interests~~non-operated 10 percent working interest in the ~~DJ Basin.~~Production Sharing Contract and Joint Operating Agreement in Angola Block 32.

Market Conditions

Prevailing prices for the various qualities of crude oil and natural gas that we produce significantly impact our revenues and cash flows. Worldwide prices have been volatile in recent years. The following table lists benchmark crude oil and natural gas price averages relative to our North America E&P and International E&P segments in the third quarter and first nine months of ~~quarters of~~ 2013 and 2012.

North America E&P

Liquid hydrocarbons – The quality, location and composition of our liquid hydrocarbon production mix ~~will~~can cause our U.S. liquid hydrocarbon realizations to differ from the WTI benchmark.

Quality – Light sweet crude contains less sulfur and tends to be lighter than sour crude oil so that refining it is less costly and produces higher value products; therefore, light sweet crude is considered of higher quality and typically sells at a price that approximates WTI or at a premium to WTI. The percentage of our North America E&P crude oil and condensate production that is light sweet crude has been increasing as onshore production from the Eagle Ford and Bakken shale plays increases and production from the Gulf of Mexico declines. In the ~~first~~third quarter and first nine months of2013, the percentage of our U.S. crude oil and condensate production that was sweet averaged 7476 percent and 75 percent compared to 5365 percent and 58 percent in the same ~~period~~periods of 2012.

Location – In recent years, crude oil sold along the United States Gulf Coast, such as that from the Eagle Ford shale, has been priced based on the Louisiana Light Sweet benchmark which prices at a premium to WTI ~~because the Louisiana Light Sweet benchmark has been tracking~~and moves similarly to Brent, while production from inland areas farther from large refineries has been ~~at a~~priced lower. During the third quarter of 2013, the WTI discount ~~to WTI.~~from Brent narrowed significantly.

Composition – The proportion of our liquid hydrocarbon sales that are NGLs continues to increase due to our development of United States unconventional liquids-rich plays. NGLs were 1416 percent of our North America E&P liquid hydrocarbon sales volumes in the third quarter and 15 percent in the first ~~quarter~~ nine months of 2013 compared to 812 percent and 10 percent in the same ~~period~~periods of 2012.

Natural gas – A significant portion of our natural gas production in the ~~lower 48 states of the United States~~U.S. is sold at bid-week prices, or first-of-month indices relative to our specific producing areas. Average Henry Hub settlement prices for natural gas were 2227 percent and 41 percent higher for the third quarter and first nine months of2013 ~~quarter of 2013~~ compared to the same ~~period~~periods of the prior year.

International E&P

Liquid hydrocarbons – Our international crude oil production is relatively sweet and is generally sold in relation to the Brent crude benchmark, which changed little comparing the third quarters of 2013 and 2012, but was 53 percent lower in the first ~~quarter~~ nine months of 2013 than in the same ~~quarter~~period of 2012.

Natural gas – Our major international natural gas-producing regions are Europe and Equatorial Guinea. Natural gas prices in Europe have been considerably higher than in the U.S. in recent years. In the case of Equatorial Guinea, our natural gas sales are subject to term contracts, making realized prices in these areas less volatile. The natural gas sales from Equatorial Guinea are at fixed prices; therefore, our reported average natural gas realized prices may not fully track market price movements.

Oil Sands Mining

The Oil Sands Mining segment produces and sells various qualities of synthetic crude oil. Output mix can be impacted by operational problems or planned unit outages at the mines or upgrader. Sales prices for roughly two-thirds of the normal output mix will track movements in WTI and one-third will track movements in the Canadian heavy sour crude oil marker, primarily Western Canadian Select ("WCS"). ~~The decrease~~An increase in the WTI benchmark ~~pricing~~prices, coupled with ~~the increased~~a smaller WCS discount from WTI in the ~~first~~third quarter of 2013 compared to the same period of 2012 ~~combined to create downward pressure on~~, is reflected in our improved average realizations. This narrowing of the discount began in March 2013.

The operating cost structure of ~~the~~our Oil Sands Mining operations is predominantly fixed and therefore many of the costs incurred in times of full operation continue during production downtime. Per-unit costs are sensitive to production rates. Key variable costs are natural gas and diesel fuel, which track commodity markets such as the Canadian Alberta Energy Company ("AECO") natural gas sales index and crude oil prices, respectively.

The table below shows benchmark prices that impacted both our revenues and variable costs for the third quarter and first nine months of ~~quarters of~~ 2013 and 2012:

Unrealized gains and losses on crude oil derivative instruments are included in total sales and other operating revenues but are not allocated to the segments. InThese crude oil derivative instruments resulted in a $61 million net unrealized loss in the third quarter and first ~~quarter~~ nine months of 2013~~, the~~ compared to a net unrealized ~~loss on crude oil derivative instruments was~~ ~~$50~~gain of $45 million ~~with no comparable crude oil derivative activity~~ in the same ~~period~~periods of 2012. See Note 1214 to the consolidated financial statements and Item 3. Quantitative and Qualitative Disclosures About Market Risk for additional information about our derivative positions.

Marketing revenues ~~decreased~~increased $~~409~~37 million in the ~~first~~third quarter ~~quarter~~of 2013 and decreased $640 million in the first nine months of of 2013 from the comparable prior-year ~~period.~~periods. North America E&P segment marketing activities, formerly referred to as supply optimization activities, which include the purchase of commodities from third parties for resale ~~have been decreasing~~and represented the majority of these variances, decreased in the first nine months of 2013 due to market dynamics. ~~Related commodity prices have also been lower~~Despite this year-to-date trend, there was a slight increase in the third quarter of 2013 ~~than in~~when compared to 2012. These activities serve to aggregate volumes in order to satisfy transportation commitments and to achieve flexibility within product types and delivery points.

Income from equity method investments decreased $8 million in the third quarter of 2013 versus the third quarter of 2012; however, it increased $4049 million in the first ~~quarter~~ nine months of 2013 from the comparable prior-year period, primarily due to higher LNG ~~realizations and partially due to higher sales volumes since turnarounds at our facilities in Equatorial Guinea reduced sale volumes in the first quarter of~~average realizations. ~~2012~~.

Net gain (loss) on disposal of assets in the first nine months of ~~quarter of~~ 2013 includes a $114 million loss on the sale of our interests in the DJ Basin, a $43 million loss on the conveyance of our interests in the Marcellus natural gas shale play to the operator, a $98 million gain on the sale of our interest in the Neptune gas plant and a ~~$46~~$55 million gain on the sale of our remaining assets in ~~Alaska and a $43 million loss on the conveyance of our interest in the Marcellus natural gas shale play to the operator.~~Alaska. The net gain on disposal of assets in the first nine months of ~~quarter of~~ 2012 consists primarily of the $166 million gain on the sale of our interests in several Gulf of Mexico crude oil pipeline ~~systems.~~systems and a $36 million loss related to our exit from Indonesia. See Note 5 to the consolidated financial statements for information about these dispositions.

Production expenses ~~increased~~decreased $6426 million in the ~~first~~third quarter ~~quarter~~ of 2013 compared to the same quarter in 2012 primarily due to lower feedstock and contract labor costs in the OSM segment, partially offset by higher production expenses in the North America E&P segment related to increased sales volumes in the Eagle Ford and Bakken shale plays. Production expenses increased $186 million in the first nine months of2013 from the comparable period of 2012. The North America E&P increase is primarily related to increased sales volumes in ~~each segment.~~Eagle Ford and Bakken, partially offset by lower Alaska production expenses due to the asset sale in the first quarter of 2013. The International E&P increase is primarily related to 2013 first production from Angola Block 31 and a planned Norway third quarter 2013 turnaround. The OSM segment increase is primarily related to a planned turnaround in the second quarter of 2013.

Marketing expenses increased $35 million and decreased $~~413~~650 million in the ~~first~~third quarter and first nine months of2013 from the same ~~period~~periods of 2012, consistent with the marketing revenue ~~decline~~changes discussed above.

Exploration expenses were ~~higher~~$17 million lower in the ~~first~~third quarter ~~quarter~~ of 2013 than in the same quarter in 2012 due to lower unproved property impairments and geological and geophysical costs partially offset by higher dry well costs, including the Sverdrup well in Norway. Exploration costs were $274 million higher in the first nine months of2013 than in the same period of 2012, primarily due to larger unproved property impairments. The first quarter of 2013 included $340 million in unproved property impairments on Eagle Ford shale leases that either ~~have~~had expired or that we do not expect to drill or extend. The following table summarizes the components of exploration expenses.

Depreciation, depletion and amortization (“DD&A”) increased $~~173~~95 million and $426 million in the third quarter and first ~~quarter~~nine months of2013 from the comparable prior-year ~~period.~~periods. Our segments apply the units-of-production method to the majority of their assets; therefore, the previously discussed increases in North America E&P sales volumes generally result in similar changes in DD&A. The DD&A rate (expense per barrel of oil equivalent), which is impacted by changes in reserves and capitalized costs, can also cause changes in our DD&A. An increase in the North America E&P DD&A rate in the third quarter and first nine months of2013 compared to the same prior-year periods was primarily due to the ongoing development programs in the Eagle Ford and Bakken shale resource plays. A slightly lower International E&P DD&A rate in the first nine months of ~~quarter of~~ 2013~~, primarily due to reserve increases at the end of 2012 for Norway,~~ compared to the same period in 2012, was primarily due to reserve increases for Norway and partially offset the impact of the higher North America E&P rate and higher sales volumes.

The following table provides DD&A rates for each segment.

Impairments in the first nine months of ~~quarter of~~ 2013 primarily related ~~primarily~~ to the Powder River Basin and to the Ozona development in the Gulf of Mexico. Impairments in the first nine months of ~~quarter of~~ 2012 were also ~~primarily~~ related to the Ozona development in the Gulf of Mexico. See Note 1113 to the consolidated financial statements for information about these impairments.

Taxes other than income include production, severance and ad valorem taxes in the United States which tend to increase or decrease in relation to sales volumes and revenues.

General and administrative expenses decreased $27 million and $9 million in the third quarter and first nine months of 2013 from the same periods in 2012. The decrease in the third quarter of 2013 is primarily due to a lower pension settlement loss in the third quarter of 2013.

Net interest and other increased $2213 million and $49 million in the ~~first~~third quarter and first nine months of2013 from the comparable ~~period~~periods of 2012 primarily due to lower capitalized interest in 2013.

Provision for income taxes ~~increased~~decreased $98492 million and $341 million in the ~~first~~third quarter ~~quarter~~and first nine months of 2013 from the comparable ~~period~~periods of 2012 primarily due to the ~~increase~~decrease in pretax income, primarily in ~~high tax rate jurisdictions.~~Libya.

The effective income tax rate is influenced by a variety of factors including the geographic sources of income and the relative magnitude of these sources of income. The provision for income taxes is allocated on a discrete, stand-alone basis to pretax segment income and to individual items not allocated to segments. The difference between the total provision and the sum of the amounts allocated to segments and to items not allocated to segments is shown in corporate and other unallocated items in the segment income table below.

Our effective income tax rates in the first ~~three~~ nine months of 2013 and 2012 were 7368 percent and 6972 percent. These rates are higher than the U.S. statutory rate of 35 percent due to earnings from foreign jurisdictions, primarily Norway and Libya, where the tax rates are in excess of the U.S. statutory rate. In Libya, where the statutory tax rate is in excess of 90 percent, sales decreased in the third quarter of 2013 due to labor strikes at the Es Sider oil terminal and there remains uncertainty around ~~sustained~~future production and sales levels. Reliable estimates of 2013 and 2012 annual ordinary income from our Libyan operations could not be made and the range of possible scenarios when including ordinary income from our Libyan operations in the worldwide annual effective tax rate calculation demonstrates significant variability. As such, for the first ~~three~~ nine months of 2013 and 2012, an estimated annual effective tax ~~rate was~~rates were calculated excluding Libya and applied to consolidated ordinary income excluding Libya and the tax provision applicable to Libyan ordinary income was recorded as a discrete item in the ~~period.~~periods. Excluding Libya, the effective tax ~~rate~~rates would be 6560 percent and 64 percent for the first ~~three~~ nine months of 2013 and 2012. In the third quarter of 2013, we recorded a net favorable tax adjustment of $42 million, largely related to greater expected utilization of foreign tax credits in future periods than previously estimated.

Critical Accounting Estimates

There have been no changes to our critical accounting estimates subsequent to December 31, ~~2012.~~2012.

Accounting Standards Not Yet Adopted

In February 2013, an accounting standards update was issued to provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date, except for obligations such as asset retirement and environmental obligations, contingencies, guarantees, income taxes and retirement benefits, which are separately addressed within United States generally accepted accounting principles ("U.S. ~~GAAP.~~GAAP"). An entity is required to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date as the sum of 1) the amount the entity agreed to pay on the basis of its arrangement among its co-obligors and 2) any amount the entity expects to pay on behalf of its co-obligors. Disclosure of the nature of the obligation, including how the liability arose, the relationship with other co-obligors and the terms and conditions of the arrangement is required. In addition, the total outstanding amount under the arrangement, not reduced by the effect of any amounts that may be recoverable from other entities, plus the carrying amount of any liability or receivable recognized must be disclosed. This accounting standards update is effective for us beginning in the first quarter of 2014 and should be applied retrospectively for those in-scope obligations resulting from joint and several liability arrangements that exist at the beginning of 2014. Early adoption is permitted. We ~~are currently evaluating the potential impact of~~do not expect this accounting standards update to have a significant impact on our consolidated results of operations, financial position ~~and~~or cash flows.

Cash Flows and Liquidity

Cash Flows

Net cash provided by operating activities was $~~1,528~~4,041 million in the first ~~three~~nine months of 2013, compared to $~~973~~2,812 million in the first ~~three~~nine months of 2012, primarily reflecting the impact of increased North America liquid hydrocarbon ~~natural gas and synthetic crude oil sales~~ volumes on operating income.

Net cash used in investing activities totaled $~~1,037~~3,411 million in the first ~~three~~nine months of 2013, compared to $~~806~~4,031 million in the first ~~three~~nine months of 2012. Significant investing activities are additions to property, plant and equipment and disposal of assets. Additions in both periods primarily related to spending on U.S. unconventional resource plays, particularly the Eagle Ford shale. Disposals of assets totaled $~~312~~402 million and $~~208~~193 million in the first ~~three~~nine months of 2013 and 2012, with 2013 net proceeds primarily related to the sales of our interests in our Alaska assets, ~~and our interest in~~ the Neptune gas ~~plant.~~plant, and the DJ Basin. In 2012, net proceeds resulted primarily from the sale of our interests in several Gulf of Mexico crude oil pipeline systems.

For further information regarding capital expenditures by segment, see Supplemental Statistics.

Net cash used in financing activities was $~~413~~954 million in the first ~~three~~nine months of 2013, compared to $~~157~~1,385 million provided by financing activities in the first nine months of 2012. During the first nine months of 2013, we repurchased $500 million of our common stock under our authorized share repurchase program. Repayments of debt were $148 million in the first ~~three~~nine months of ~~2012~~2013~~. Repayments of debt at maturity were~~ and $~~114~~111 million in the first ~~three months of 2013~~ ~~and~~ ~~$53 million~~ ~~in the~~ ~~first three~~nine months of 2012. We also ~~repaid all~~drew a net $~~200~~1,839 million of ~~our outstanding~~ commercial paper ~~during~~in the first ~~three~~nine months of ~~2013.~~2012. Dividends paid of ~~approximately~~ $~~120~~376 million and $360 million were a significant use of cash in both nine-month periods.

Liquidity and Capital Resources

Our main sources of liquidity are cash and cash equivalents, internally generated cash flow from operations, the issuance of notes, our committed revolving credit facility and sales of non-strategic assets. Our working capital requirements are supported by these sources and we may issue commercial paper backed by our $2.5 billion revolving credit facility to meet short-term cash requirements. Because of the alternatives available to us as discussed above, ~~and our access to capital markets,~~ we believe that our short-term and long-term liquidity is adequate to fund not only our current operations, but also our near-term and long-term funding requirements including our capital spending programs, dividend payments, defined benefit plan contributions, repayment of debt maturities, share repurchase program and other amounts that may ultimately be paid in connection with contingencies.

Capital Resources

Credit Arrangements and Borrowings

At ~~March 31,~~September 30, 2013, we had no borrowings against our revolving credit facility orand $200 million outstanding under our U.S. commercial paper program that is backed by the revolving credit facility. During the first ~~quarter~~nine months of 2013,~~, $200~~$4,975 million of commercial paper was issued and ~~$400~~$4,975 million of commercial paper was repaid.

At ~~March 31,~~September 30, 2013, we had ~~$6,544~~$6,501 million in long-term debt outstanding, $68 million of which is due within one year. We do not have any triggers on any of our corporate debt that would cause an event of default in the case of a downgrade of our credit ratings.

Anticipated Asset Disposals

The previously discussed sale of our interest in Angola Block 31 and the agreement in principle to sell our interest in Angola Block 32 are both expected to close in the fourth quarter of 2013, subject to the execution of definitive agreements for Block 32 and government and regulatory approvals. Anticipated proceeds from these transactions are $1.5 billion and $590 million, respectively, before closing adjustments. We expect to use a portion of the proceeds to repurchase common shares as discussed below and the remainder to strengthen our balance sheet and for general corporate purposes.

Shelf Registration

We ~~have a universal shelf registration statement filed with the SEC under which we, as~~are a "well-known seasoned issuer" for purposes of SEC rules, ~~have the ability~~thereby allowing us to use a universal shelf registration statement should we choose to issue and sell ~~an indeterminate amount of~~ various types of equity and debt securities. Beginning in the first quarter of 2013, we changed our reportable segments and ~~equity securities.~~expect to recast all periods presented to reflect these new segments in our consolidated financial statements no later than upon filing our 2013 Annual Report on Form 10-K with the SEC. When appropriate, we will update and file our universal shelf registration statement.

Capital Requirements

On ~~April 24,~~October 30, 2013, our Board of Directors approved a dividend of 1719 cents per share for the ~~first~~third quarter of 2013, payable ~~June~~December 10, 2013 to stockholders of record at the close of business on ~~May 16,~~November 20, 2013.

As of ~~March 31,~~September 30, 2013, we plan to make contributions of up to ~~$55~~$17 million to our funded pension plans during the remainder of 2013.

Since January 2006, our Board of Directors has authorized a common share repurchase program totaling $5 billion. As of September 30, 2013, we had repurchased 92 million common shares at a cost of $3,722 million, with 66 million shares purchased for $2,922 million prior to the spin-off of our downstream business, 12 million shares acquired at a cost of $300 million in ~~2013, $17~~the third quarter of 2011 and 14 million shares acquired at a cost of $500 million during the third quarter of 2013. An additional $500 million repurchase of common shares is anticipated to be completed after closing the previously discussed sale of our interest in Angola Block 31, which ~~were made~~is expected in ~~April~~the fourth quarter of 2013. Purchases under the repurchase program may be in either open market transactions, including block purchases, or in privately negotiated transactions. This program may be changed based upon our financial condition or changes in market conditions and is subject to termination prior to completion. The program’s authorization does not include specific price targets or timetables. The timing of purchases under the program will be influenced by cash generated from operations, proceeds from potential asset sales, cash from available borrowings and market conditions.

Our opinions concerning liquidity and our ability to avail ourselves in the future of the financing options mentioned in the above forward-looking statements are based on currently available information. If this information proves to be inaccurate, future availability of financing may be adversely affected. Factors that affect the availability of financing include our performance (as measured by various factors including cash provided from operating activities), the state of worldwide debt and equity markets, investor perceptions and expectations of past and future performance, the global financial climate, and, in particular, with respect to borrowings, the levels of our outstanding debt and credit ratings by rating agencies. The discussion of liquidity above also contains forward-looking statements regarding the timing of closing the sales of our interests in Angola Blocks 31 and 32, including the use of proceeds, and the timing and amount of repurchasing additional common stock. The timing of closing the sale of our interest in Angola Block 31 is subject to the satisfaction of customary closing conditions and obtaining necessary government and regulatory approvals. The sale of our interest in Angola Block 32 is subject to the execution of definitive agreements and obtaining necessary government approval. The expectations with respect to the use of proceeds from the sale of our interests in Angola Block 31 and 32 and the timing and amount of repurchasing additional common stock could be affected by changes in the prices and demand for liquid hydrocarbons and natural gas, actions of competitors, disruptions or interruptions of our exploration or production operations, unforeseen hazards such as weather conditions or acts of war or terrorist acts and other operating and economic considerations. The discussion of liquidity above also contains forward-looking statements regarding planned funding of pension plans, which are based on current expectations, estimates and projections and are not guarantees of actual performance.

Actual results may differ materially from these expectations, estimates and projections and are subject to certain risks, uncertainties and other factors, some of which are beyond our control and are difficult to predict. Some factors that could cause actual results to differ materially include prices of and demand for liquid hydrocarbons and natural gas, ~~and synthetic crude oil,~~ actions of competitors, disruptions or interruptions of our production or oil sands mining and bitumen upgrading operations due to unforeseen hazards such as weather conditions, acts of war or terrorist acts and the governmental or military response thereto, and other operating and economic considerations.

Contractual Cash Obligations

As of ~~March 31,~~September 30, 2013, our total contractual cash obligations were consistent with December 31, ~~2012.~~2012.

Environmental Matters

We have incurred and will continue to incur substantial capital, operating and maintenance, and remediation expenditures as a result of environmental laws and regulations. If these expenditures, as with all costs, are not ultimately reflected in the prices of our products and services, our operating results will be adversely affected. We believe that substantially all of our competitors must comply with similar environmental laws and regulations. However, the specific impact on each competitor may vary depending on a number of factors, including the age and location of its operating facilities, marketing areas and production processes.

There have been no significant changes to our environmental matters subsequent to December 31, ~~2012.~~2012.

Other Contingencies

Sensitivity analysis of the projected incremental effect of a hypothetical 10 percent change in interest rates on financial assets and liabilities as of ~~March 31,~~September 30, 2013 is provided in the following table.


					Incremental							Incremental
					Change in							Change in
(In millions)	Fair Value				Fair Value			Fair Value				Fair Value
Financial assets (liabilities): ^(a)
Interest rate swap agreements	$	18		^(b)	$	2		$	11		^(b)	$	5
Long-term debt, including amounts due within one year	$	(7,347	)	^(b)	$	(231	)	$	(6,941	)	^(b)	$	(236	)


^(a)	Fair values of cash and cash equivalents, receivables, commercial paper, accounts payable and accrued interest approximate carrying value and are relatively insensitive to changes in interest rates due to the short-term maturity of the instruments. Accordingly, these instruments are excluded from the table.


^(b)	Fair value was based on market prices where available, or current borrowing rates for financings with similar terms and maturities.

The aggregate cash flow effect on foreign currency derivative contracts of a hypothetical 10 percent change in exchange rates at ~~March 31,~~September 30, 2013 would be $6152 million.

Item 4. Controls and Procedures

An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in ~~Rule~~Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) was carried out under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our company's design and operation of disclosure controls and procedures were effective ~~for the period ending March 31, 2013.~~ as of September 30, 2013.

In the first quarter of 2013, we completed the update of our existing Enterprise Resource Planning ("ERP") system. This update included a new general ledger, consolidations system and reporting tools. ~~There~~During the quarter ended September 30, 2013, there were no changes in our internal control over financial reporting that have materially affected, or were reasonably likely to materially affect, our internal control over financial reporting.

Part II – OTHER INFORMATION

Item 1. Legal Proceedings

Litigation

In March 2011, Noble Drilling (U.S.) LLC (“Noble”) filed a lawsuit against us in the District Court of Harris County, Texas, alleging, among other things, breach of contract, breach of the duty of good faith and fair dealing, and negligent misrepresentation, relating to a multi-year drilling contract for a newly constructed drilling rig to be deployed in the U.S. Gulf of Mexico. We filed an answer in April 2011, contending, among other things, failure to perform, failure to comply with material obligations, failure to mitigate alleged damages and that Noble failed to provide the rig according to the operating, performance and safety requirements specified in the drilling contract. In April 2013, we filed a counterclaim against Noble alleging, among other things, breach of contract and breach of the duty of good faith relating to the multi-year drilling contract. The counterclaim also included a breach of contract claim for reimbursement for the value of fuel used by Noble under an offshore daywork drilling contract. ~~We are vigorously defending~~The parties have reached a tentative settlement of this litigation. ~~The ultimate outcome~~We believe that the settlement of this ~~lawsuit, including any financial~~litigation will not have a material adverse effect on ~~us, remains uncertain. We do not believe an estimate~~our consolidated results of ~~a reasonably probable loss (or range of loss) can be made for this lawsuit at this time.~~

~~Environmental~~

~~We continue to work with the North Dakota Department of Health to resolve voluntary disclosures we made in 2009 relating to potential Clean Air Act violations relating to our~~ operations, ~~on state lands in the Bakken shale. The proposed settlement of the fine is $169,800 and is expected to be executed by the parties in the second quarter of 2013.~~financial position or cash flows.
