FIRST QUARTER 2013

U.S. ONSHORE OIL GROWTH Oil sales volumes from Anadarko’s U.S. onshore assets averaged more than 97,000 barrels of oil per day (BOPD)

in the 1st quarter, an increase of 35% over the 1st quarter

of 2012. This higher-margin growth was driven by increased activity in the Wattenberg, Eagleford Shale, East Texas HZ and Permian oil plays, and is expected to

continue throughout 2013.

HEIDELBERG CARRIED INTEREST AGREEMENT During the quarter, Anadarko signed a definitive agreement to enter into a carried-interest arrangement for a portion of Anadarko’s ownership of the Heidelberg development project in the deepwater Gulf of Mexico, which is estimated to hold 200 - 400 million barrels of recoverable resources. The carried interest arrangement closed during the 2nd quarter of 2013, and is effective as of April 1, 2013. Under the terms of the agreement, Anadarko will be carried for $860 million, which represents nearly all its expected capital investments through the anticipated

date of first oil in mid-2016, and it established a market value of approximately $3 billion for Anadarko’s interest. In exchange, Anadarko conveyed a 12.75-percent working interest in the Heidelberg development. Anadarko will

continue as operator with a 31.5-percent working interest.

FIRST OIL PRODUCTION AT EL MERK Initial oil production began flowing through the first of three facilities at Anadarko’s El Merk project in Algeria. Production is expected to increase during the year, and Anadarko anticipates production to reach 30,000

barrels of oil per day, net, around year end.

FIRST-QUARTER HIGHLIGHTS

SHENANDOAH BASIN SUCCESS The company’s Shenandoah-2 well in the deepwater Gulf of Mexico encountered more than 1,000 net feet of oil pay in multiple high-quality, Lower Tertiary reservoirs. Similar to the initial Shenandoah discovery, well log and pressure data from the Shenandoah-2 well indicated excellent-quality reservoir and fluid properties. The well was drilled more than 1 mile southwest and approximately 1,700 feet structurally down-dip from the Shenandoah-1 discovery well to test the extent of the accumulation. The targeted sands were full to base with no oil-water contact. Anadarko is the operator of the Shenandoah discovery with a 30-percent

working interest.

FIRST QUARTER 2013

SALES VOLUMES First-quarter sales volumes were above the high end of guidance at a record of more than 71 million barrels of oil equivalent (BOE) or 793,000 BOE per day (BOE/d), an increase of 89,000 BOE/d over the 1st quarter of

2012. The company achieved liquids sales volumes of 345,000 barrels per day, about 74% of which were oil. These liquids sales volumes were driven by significant growth in the U.S. onshore, particularly in the Wattenberg, Eagleford Shale, East Texas HZ and Permian oil, as well as by strong oil production rates and an accelerated tanker at the Jubilee field in Ghana. Anadarko has increased its full-year 2013 sales-volumes guidance to a

range of 279 to 287 million BOE from the previous

range of 279 to 285 million BOE.

CAPITAL SPENDING Capital investments during the 1st quarter were below the

guidance range at approximately $1.4 billion, excluding capital investments associated with Western Gas Partners, LP (WES). Capital expenditure expectations for the full-year 2013 remain within the range of $7.2 to $7.6 billion,

excluding WES capital spending.

FIRST QUARTER 2013 FOCUSED ON CONTINUOUS IMPROVEMENT

DRILLING EFFICIENCIES: In the Wattenberg field, the company reduced spud-to-rig-

release cycle times over the 4th quarter of 2012 to 10.8 days from 12.2 days. Cycle time improvements times were also achieved in the Marcellus field, with spud to rig

release reduced from 18.5 days to 16.5 days in the quarter.

COMPLETIONS EFFICIENCIES: Anadarko continues to leverage existing infrastructure and

new technologies to safely reduce the cost and cycle times associated with completing new wells. In the Wattenberg field, the company is now utilizing a water trunkline to deliver water for horizontal completion operations. During the 1st quarter, approximately 22,500 truck trips were eliminated in Wattenberg, helping reduce emissions and improve safety, while also reducing

costs through transportation savings.

LEASE OPERATING EXPENSE (LOE) IMPROVEMENTS: Since 2008, Anadarko has realized a 31% reduction in

its LOE/BOE.

ROCKIES

RECORD SALES VOLUMES Anadarko’s Rockies assets delivered record sales volumes of approximately 327,400 BOE/d in the 1st quarter. These record sales volumes increased approximately 5% over the same period in 2012 and include a 38% increase in oil sales volumes. Many of the Rockies assets were in ethane rejection during the 1st quarter due to the

current pricing environment. The company averaged 17 rigs during the quarter and drilled a total of 128 wells, with the majority of the activity taking place in the liquids-rich Wattenberg field.

FIRST QUARTER 2013

WATTENBERG: The Wattenberg field achieved another quarterly record,

delivering average net sales volumes of 113,100 BOE/d, representing 39% sequential growth over the 1st quarter of 2012. Exceptional results in the Wattenberg HZ drilling program resulted in a 45% increase in liquids sales volumes compared to the 1st quarter of

2012.

The company operated 11 horizontal rigs during the quarter, drilling a total of 73 horizontal wells. The company currently is producing more than 60,000 BOE/d gross from 231 operated horizontal wells and

generating rates of return in excess of 100%.

Anadarko continues to proactively pursue additional midstream and marketing solutions to enable continued Wattenberg production growth. Specifically, progress continues on the company’s 300 MMcf/d Lancaster cryogenic plant, as well as the Texas Express and Front Range NGL pipelines, all of which are expected to be in service by early 2014, which will provide additional

access to premium Gulf Coast markets.

POWDER RIVER OIL: Drilling activity continued during the quarter in the

Powder River Basin horizontal program, where multiple oil objectives are currently being tested across the company’s ~350,000 net-acre position. The company had one operated rig drilling horizontal wells in the

basin, with 13 horizontal wells producing.

GREATER NATURAL BUTTES: Gross sales volumes averaged approximately 561 million

cubic feet equivalent per day (MMcfe/d) for the quarter.

FIRST QUARTER 2013

PRODUCING PROPERTIES CAESAR/TONGA:

Green Canyon 683/726/727/770 (APC WI 33.75%) Anadarko finished drilling its fourth development

well in the field and encountered 256 net feet of oil pay in Miocene-aged sands. This well is expected to be completed and brought on line during the 2nd quarter of 2013.

INDEPENDENCE HUB: Independence Hub averaged approximately 278

MMcf/d of gross production (206 MMcf/d net) during the quarter, compared to 265 MMcf/d of gross production (191 MMcf/d net) during the 4th quarter

of 2012.

DEVELOPMENT LUCIUS:

Keathley Canyon 874/875/918/919 (APC WI 27.8%) During the quarter, Anadarko completed drilling an

appraisal well and a development well on the eastern flank of the structure. The appraisal well encountered 141 net feet of oil pay in the Pliocene objective, establishing the oil-water contact for the eastern flank as expected. The well also encountered 120 net feet of oil pay in Miocene sands. The well was then sidetracked as an up-dip producer and encountered 685 net feet of oil and gas pay in the Pliocene. Two additional development wells are scheduled to be drilled in 2013 before the rig will

begin completion activities in the field.

The Lucius truss spar recently began transportation to the Gulf of Mexico, with first production anticipated

in the second half of 2014.

APPRAISAL HEIDELBERG:

Green Canyon 859/860/903/904/948 (APC WI 31.5%) During the quarter, Anadarko announced an

agreement to transfer a 12.75% working interest in the field in exchange for an $860-million carry of Anadarko’s future capital investment in the project, which represents nearly all of its expected capital requirement through first production. The transaction closed during the 2nd

quarter and is effective as of April 1, 2013.

Anadarko began fabricating the spar hull for the field, which will be an 80,000 BOPD Lucius look-a-like facility, and is expected to be on line in 2016. When

planning the facility, the company leveraged the Lucius design and construction crews, enabling Anadarko to accelerate first production by almost

18 months.

SHENANDOAH:

Walker Ridge 51/52 (APC WI 30%) The Shenandoah-2 well encountered more than

1,000 net feet of oil pay in multiple high-quality Lower Tertiary reservoirs. Similar to the initial Shenandoah discovery well, log and pressure data from the Shenandoah-2 well indicated excellent-quality reservoir and fluid properties. The targeted sands were full to base with no oil-water contact. The company appraised the down-dip extent of the Shenandoah discovery, where more than 300 net feet of high-quality oil was encountered in the discovery well. The appraisal well was approximately 1,700 feet down-dip and more than 1 mile southwest of the original discovery well. Anadarko is the operator of the Shenandoah discovery with a 30% working interest. Anadarko plans further appraisal activity later in

2013.

VITO:

Mississippi Canyon 984/940 (APC WI 18.67%) The operator continues to evaluate development

options for this 300 million-plus BOE project. The operator drilled a successful appraisal well to test Miocene objectives approximately one mile west and 2,000 feet up-dip of the original discovery well and found approximately 300 net

feet of oil pay.

FIRST QUARTER 2013

EXPLORATION CORONADO AND YUCATAN:

Walker Ridge 143/95 (APC WI 15%) During the quarter, the Coronado discovery

encountered more than 400 net feet of oil pay in high-quality, Lower Tertiary reservoirs, approximately 9 miles east of the Anadarko-operated Shenandoah discovery. Anadarko holds a 15-percent working

interest in the Coronado discovery.

Drilling continues at the Yucatan prospect, where Anadarko holds a 15% working interest. Yucatan is

located approximately 3 miles south and syncline-separated from the Anadarko-operated Shenandoah discovery. The well is testing Lower Tertiary reservoirs in a trap similar to the nearby Shenandoah and

Coronado discoveries.

PHOBOS:

Sigsbee Escarpment 39 (APC WI 30%) Early in the 2nd quarter, the company announced

that Phobos encountered approximately 250 net feet of high-quality oil pay in Lower Tertiary-aged reservoirs. Phobos tested a large, multi-block, four-way closure approximately 11 miles south of the Lucius

field. This is the first well to be drilled in the Sigsbee Escarpment area of the Gulf of Mexico, and Anadarko’s interest was carried as a result of two separate farm-

out agreements.

RAPTOR:

DeSoto Canyon 535 (APC WI 50%) The company is currently drilling a 25,000-foot

Jurassic-Norphlet test in 8,200 feet of water. The prospect is a large, multi-block, four-way closure and is the company’s first test of the Norphlet play in the

eastern Gulf of Mexico.

FIRST QUARTER 2013

DEVELOPMENT ALASKA: Gross production from the Colville River Unit averaged

approximately 65,400 BOPD during the 1st quarter.

ALGERIA: At El Merk, the partnership achieved first production

from the first of three planned facilities. Oil sales volumes are expected to increase steadily throughout 2013 as two additional production

facilities and three other fields are brought on line.

During the quarter, gross production from the Hassi Berkine South and Ourhoud central processing facilities averaged approximately 299,000 BOPD. Production increased from the prior quarter due to completion of planned maintenance at the HBNS

and Ourhoud facilities.

CHINA: Effective Jan. 1, 2013, the Chinese National Offshore

Oil Corporation (CNOOC) assumed the role of operator

of the Bohai Bay asset.

Gross production for the quarter averaged 32,200 BOPD. The field is expected to average 30,000 to 35,000 BOPD during 2013 due to planned maintenance activity. The operator is currently running one rig and expects to maintain an active

development drilling program throughout the year.

GHANA: During the 1st quarter, Jubilee field gross production

averaged well in excess of 100,000 BOPD. Plans are under way to expand gas handling capacity at the production facility, which along with additional wells and acid stimulations, are expected to allow for

increased oil volumes throughput in late 2013.

The partnership continues to advance the TEN (Tweneboa, Enyenra and Ntomme complex) plan of development toward sanction with the Government

of Ghana.

MOZAMBIQUE:

FIRST QUARTER 2013

EXPLORATION GHANA:

Deepwater Tano (APC WI 18%) The Enyenra-6 appraisal well was successfully

drilled approximately 2 miles south of the Enyenra-4 appraisal well and will be utilized in the future

development.

The Sapele exploration well was found to be water-bearing during the 1st quarter. Appraisal work

on the Wawa discovery is planned for 2013.

MOZAMBIQUE:

Offshore Area 1 (APC WI 36.5%, operator) Subsequent to quarter close, the Orca exploration

well reached total depth. The well encountered approximately 190 net feet of natural gas pay in a single Paleocene sand reservoir. Additional appraisal

wells are planned for later in 2013.

The Tubarão-2 well encountered thick, well-developed sand, but was water-bearing. Pressure data obtained in the well allowed for the identification of a gas-water contact for the field, and will be used to help size the discovery and optimize the development

plan.

CÔTE D’IVOIRE:

Block CI-103 (APC WI 45%) The Calao exploration well commenced drilling

early in the 2nd quarter and will test fan systems

adjacent to the Paon discovery.

The Paon appraisal plan is under evaluation with an appraisal well planned for later in 2013. The first appraisal well will test the down-dip extent of the discovery interval, as well as several exploration

targets.

BRAZIL:

Block BM-C-30 (APC WI 30%, operator), BM-C-32 (APC WI 33%) On BM-C-32, a drillstem test was completed at the

Itaipu-1 discovery well. The well flowed at rates up to

5,600 BOPD.

KENYA:

Blocks L-5,L-7,L-11A,L-11B,L-12 (APC WI 45%, operator) The company is currently drilling the Kiboko prospect
