EARNINGS RELEASE OPERATIONS SUPPLEMENT

NOTICE TO INVESTORS This earnings release operations supplement contains certain "forward-looking statements" within the meaning of Section 27A of

the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended and, whenever

possible, are identified by use of the words such as “anticipates,” “intends,” “plans,” “seeks,” “believes,” “estimates,” “expects” and

similar references to future periods. Any matters that are not historical facts are forward-looking and, accordingly, involve

estimates, assumptions, risks and uncertainties, including, without limitation, our assumptions and estimates about the market

prices of oil, natural gas, NGLs and other products or services, our commodity hedging arrangements, the supply and demand for oil,

natural gas, NGLs and other products or services, production and reserve levels, drilling risks, the number of wells drilled, economic

and competitive conditions, the availability of capital resources, capital expenditure and other contractual obligations, and our

ability to complete, test and produce the wells identified in this supplement. Because such statements involve risks and

uncertainties, Apache’s actual results and performance may differ materially from the results expressed or implied by the forward-

looking statements contained in this supplement. Other important factors that could cause actual results to differ materially from

expected results are described in “Risk Factors” in our most recently filed Annual Report on Form 10-K, recent Quarterly Reports on

Form 10-Q and amendments thereto, available on our Web site and in our other public filings and press releases. There is no

assurance that Apache's expectations will be realized, and readers are cautioned not to place undue reliance on forward looking

statements, which speak only as of the date hereof. Unless otherwise required by law, we assume no duty to update these

statements as of any future date.

Cautionary Note to Investors: The United States Securities and Exchange Commission ("SEC") permits oil and gas companies, in their

filings with the SEC, to disclose only proved, probable, and possible reserves that meet the SEC's definitions for such terms. Apache

may use certain terms in this earnings release operations supplement, such as “resources,” “potential resources,” “resource

potential,” “reserves potential,” and other similar terms that the SEC guidelines strictly prohibit Apache from including in filings with

the SEC. Such terms do not take into account the certainty of resource recovery, which is contingent on exploration success,

technical improvements in drilling access, commerciality and other factors, and are therefore not indicative of expected future

resource recovery and should not be relied upon. Investors are urged to consider carefully the disclosure in Apache’s Annual Report

on Form 10-K for the fiscal year ended December 31, 2013, available from Apache at www.apachecorp.com or by writing Apache at:

2000 Post Oak Blvd., Suite 100, Houston, Texas 77056 (Attn: Corporate Secretary). You can also obtain this report from the SEC by

calling 1-800-SEC-0330 or from the SEC's website at www.sec.gov.

Certain information may be provided in this supplement that includes financial measurements that are not required by, or presented

in accordance with, generally accepted accounting principles (GAAP), including these measures: adjusted earnings, pre-tax margin,

and cash from operations. These non-GAAP measures should not be considered as alternatives to GAAP measures, such as net

income or cash from operating activities, and may be calculated differently from, and therefore may not be comparable to, similarly

titled measures used at other companies. Reconciliation to the most directly comparable GAAP financial measure has been provided

on our website at www.apachecorp.com/financialdata.

None of the information contained in this document has been audited by any independent auditor. This supplemental document is

prepared as a convenience for securities analysts and investors and may be useful as a reference tool. Apache intends to continue

to publish this supplement in conjunction with our quarterly earnings release, but may elect to modify the format or discontinue

publication at any time, without notice to securities analysts or investors.

FIRST QUARTER 2014


APACHE WORLDWIDE OPERATIONS

Overview North America onshore liquids grew 21 percent year-over-year and 6

percent over the previous quarter led by strong results in our Permian

region. Total North America onshore liquids volumes reached a record

198,500 Bbls/d.

Total worldwide reported production during the quarter was 640

thousand barrels of oil equivalent per day (Mboe/d), 672 Mboe/d

including discontinued operations from Argentina. Liquids production

from continuing operations comprised 58 percent of the total, up from

57 percent in the previous quarter.

Taking into account divestments, on a pro forma basis excluding

noncontrolling interest and tax barrels in Egypt, quarterly production

averaged 548 Mboe/d compared to a 2013 average of 537 Mboe/d.

Strong operational results were partially offset by weather-related

downtime in our Central and North Sea regions coupled with scheduled

downtime in Australia.

Apache averaged 117 rigs worldwide during the first quarter, 71 percent

of which were focused in North America.

The company completed 346 gross wells during the quarter, 88 percent in onshore North America.

*The number of wells reported as drilled and/or completed could be subject to reclassification which may cause adjustments to reported amounts in future periods. The number of wells reported is subject to SEC standards and therefore, along with other SEC guidelines, includes completed wells only. Production data referenced is based on continuing operations unless otherwise stated.

FIRST QUARTER 2014


NORTH AMERICA Permian First-quarter 2014 production in the Permian averaged a record 149,564

barrels of oil equivalent per day (Boe/d) (76 percent liquids), up 12 percent

over the previous quarter.

The substantial growth during the quarter was driven by successful

horizontal drilling programs across the basin and led by the Wolfcamp

shale.

The Permian region averaged 38 operated drilling rigs, down three net rigs

from the previous quarter with an additional rig drilling horizontal wells and four fewer rigs drilling vertical wells.

Overall the region spud 202 gross operated wells during the quarter, 80 horizontal and 122 vertical.

WOLFCAMP SHALE

Apache has an estimated 502,000 gross acres (401,000 net) prospective for Wolfcamp Shale.

The Barnhart area of Irion County remained extremely active ramping back up to six horizontal rigs. First-quarter

activity focused on drilling 12 Upper and 8 Middle Wolfcamp wells, all with lateral lengths drilled to 1.5 miles.

Additionally, Apache was also active in Reagan and Uptown counties of the southern Midland Basin. Seven rigs

drilled across three main development fields – Powell, Scottish Rights Hospital (SRH) and Weatherby.

CLINE SHALE Apache has an estimated 640,000 gross acres (510,000 net) prospective for Cline Shale.

The Lower Cline inventory continues to grow and various alterations to completion and fracture stimulation

parameters are being tested to maximize the rate and reserves recovered.

A total of 35 gross wells are planned for 2014.

CENTRAL BASIN PLATFORM (CBP) Apache has an estimated 1.8 million gross acres (850,000 net) in the CBP.

Apache continues to have success targeting the Wichita Albany play where three horizontal wells were spud and

six were completed during the first quarter.

NORTHWEST SHELF - YESO Apache has approximately 115,000 gross acres (95,000 net) in the Yeso play.

Three drilling rigs remained active during the first quarter and 25 wells were spud, including four horizontal and 21

vertical wells.

Completion operations on the Cedar Lake horizontal program commenced during the fourth quarter of last year.

As most of these wells have cleaned up, they began reaching their peak rates by the end of the first quarter 2014.

Apache plans to drill approximately 20 horizontal wells and 75 vertical by the end of the year.

DELAWARE BASIN Apache has an estimated 550,000 gross acres (215,000 net) in the Delaware Basin.

Apache entered the first quarter running three rigs in the Pecos Bend field, spudding a total of five wells and

completing four targeting three landing zones: the 2nd

FIRST QUARTER 2014


Central First-quarter 2014 production in the Central Region was 89,524 Boe/d,

down 4 percent over the fourth quarter of 2013 due to a combination of

downtime and outages caused by severe winter weather that not only

impacted production but also set back our drilling and completion

schedules.

Liquids now constitute 52 percent of production (oil is 24 percent), up

from 46 percent in the first quarter of 2013.

For the quarter, the Central Region averaged 26 drilling rigs and drilled 69 gross (44 net) wells.

GRANITE WASH Apache holds approximately 855,000 gross (435,000 net) acres prospective for the Granite Wash.

In the Stiles Ranch area in Wheeler County, two horizontal Caldwell wells were completed: The Bartz 19 #29-19H

achieved 30-day initial production rates of 327 Bo/d and 6,200 Mcf/d; and the Bartz 19 #28-19H realizing 30-day

initial production rates of 160 Bo/d and 5,300 Mcf/d.

TONKAWA Apache holds an estimated 822,000 gross (407,000 net) acres prospective for the Tonkawa.

Apache drilled or participated in 22 Tonkawa wells during the first quarter.

Apache continues to reduce costs in the formation with the most recent drilling and completion costs coming in

just over $4 million.

MARMATON Apache holds an estimated 609,000 gross (295,000 net) acres in the Marmaton.

Apache continues to see positive results in its Lower Marmaton drilling program and plans to increase the number

of expected wells drilled this year to 30.

COTTAGE GROVE Apache holds an estimated 222,000 gross (93,000 net) acres in the oil-rich Cottage Grove.

Apache extended its Oklahoma Cottage Grove play with the Taylor 30-12-22 #1H located in Beckham County which

produced at a 30-day average rate of 1,100 Bo/d and 956 Mcf/d. The well has since been offset by two additional

tests. The Taylor 19-12-22 #1H and the Taylor 24-12-23 #1H are each producing in excess of 1,500 Bo/d with just

over a quarter of the frac load recovered.

CANYON WASH/CANYON LIME Apache holds an estimated 150,000 gross (100,000 net) acres prospective for the Canyon Wash in the Bivins Ranch

area (Whittenburg Basin).

To date, Apache has drilled just over two dozen vertical wells into the Paint Ridge field.

Apache also drilled its first horizontal Canyon Lime well. The Bivins East 41H was drilled to a vertical depth of

roughly 9,500 feet with a one mile lateral and is currently flowing back.

Two additional Canyon Lime wells are currently being drilled. In addition to horizontal Canyon Lime wells, Apache

plans to drill its first horizontal Canyon Sand wells early in the second quarter.

Oil production for the quarter was 10,975 Bbls/d, which is 6 percent

above fourth quarter 2013 oil production of 10,397 Bbls/d. This

increase is primarily from new Eagle Ford completions.

Apache averaged three rigs in the Eagle Ford and two rigs in South

Louisiana for a total of five operated drilling rigs while completing a total of three gross (two net) wells.

Early tests in Apache’s Eagle Ford acreage showed promising results.

Activity in the Golden Meadow Field kicked off early with great success. Recompletions accounted for a 692 Boe/d

Canada First-quarter 2014 production in Canada, which includes Kitimat upstream

production, was 88,310 Boe/d. Total liquids production averaged 25,358

Bbls/d for the first quarter, up 10 percent from the fourth-quarter volumes

of 22,965 Bbls/d, due to successful horizontal drilling in House Mountain

and new liquids-rich production from West 5 and Kaybob Bluesky areas.

Apache had record production in Kaybob during the first quarter of 2014.

Eight wells were spud in Bluesky and five have been completed with an

average test rate of 4.7 MMcf/d and average liquids yields of 67 Bbls/MMcf.

Apache brought online its first horizontal Montney liquids-rich well in the Wapiti area and drilled its second liquids-

rich Duvernay well in the Kaybob area, both with encouraging results.

On April 30, 2014, Apache completed the sale of its Ojay, Noel and Wapiti areas in Alberta and British Columbia.

These are primarily dry gas-producing properties comprising 622,600 gross acres (328,400 net acres). In the Wapiti

area, Apache will retain 100 percent of its working interest in horizons below the Cretaceous including rights to the

liquids-rich Montney and other deeper horizons. During 2013, production from the fields to be divested averaged

101 MMcf/d of natural gas and 1,500 Bbls/d of liquid hydrocarbons (18,400 Boe/d).

KITIMAT UPSTREAM (50 PERCENT APA) During the first quarter, Kitimat Upstream production in the Horn River and Liard Basins averaged 58 MMcf/d net

to Apache’s interest, down 8 percent from fourth quarter 2013 due mainly to a planned shut-in for pad drilling (D-

28-B horizontal) and well testing in both basins, plus natural declines.

Six rigs were drilling at the end of the first quarter including: three on vertical tenure wells; one on the 28-B

horizontal tenure / production well, which is scheduled to be on production in the fourth quarter; one on the

three-well horizontal “13-K South Pad” expected to rig release in early 2015; and one on the seven-well horizontal

“3-K North Pad,” which has an expected rig release date of fourth quarter 2015. No wells were drilled for

production during the quarter.

Operations started on the 2013/2014 winter 3D seismic programs in the first quarter, with a 515-square-mile

acquisition expected to be completed by early second quarter 2014.

INTERNATIONAL Australia First-quarter 2014 production was 52,790 Boe/d, down 11 percent from

fourth-quarter 2013. Gas volumes were down as a result of contract

timing, while oil volumes were down due to the scheduled Van Gogh

downtime for FPSO upgrades. It is anticipated the FPSO will return in

the third quarter to begin production from the Coniston oil field. Oil

downtime was partially offset by first oil from the BHP-operated Upper Pyrenees well.

During the first quarter, the region operated two semi-submersible drilling rigs and drilled four gross (two net)

wells.

The Ningaloo Vision FPSO entered the Keppel Shipyard in Singapore where the hull steel inspections were

completed and steel renewal commenced.

The project remains on track for start-up in the third quarter of 2014.

JULIMAR (65 PERCENT APA) / WHEATSTONE LNG (13 PERCENT APA) Wheatstone progress is 33-percent complete. Platform fabrication continued with all topside deck blocks and

steel gravity substructure blocks erected. Operations for laying the trunkline to shore started in the first quarter.

At the LNG plant site, the first pour of the LNG tank foundations took place and plant piling work and construction

of the marine offloading facility continued.

At Julimar, drilling of the five development wells resumed on the intermediate hole sections and the first subsea

trees were installed. During the quarter, the four-inch MEG pipeline was laid and the first of the pipeline

structures was installed subsea. The project is 56-percent complete.

UPPER PYRENEES /MOONDYNE (28.57 PERCENT APA) All six wells in this add-on development to Pyrenees were drilled and completed in the first quarter.

Upper Pyrenees commenced production at an average gross rate of 21,000 Bo/d.

Moondyne installation remains on track for first production in the second quarter.

Egypt In Egypt, Apache’s operations continue uninterrupted. First

quarter gross liquids production was 199,268 Bo/d and

gross gas production was 921 MMcf/d, for a total of

352,841 Boe/d.

Apache averaged 27 rigs in the first quarter and drilled a

total of 32 gross (28 net) wells.

Apache maintains an active exploration program. In Khalda

seven exploration and appraisal wells were drilled to total

depth with three discoveries. Two significant new field

discoveries were made at Herunefer-1X in the Khalda Offset (East) Concession and Bat-1X, a stratigraphic play in

the South Umbarka Concession’s Khepri-Sethos Development Lease. Stratigraphic traps and Paleozoic plays

continue to develop within the Khalda Prospect portfolio, offering upside potential for exploration drilling in future

years.

During the quarter, Apache was granted two new Development Leases, the Apries Development Lease and the

North Tarek H Development Lease. New well discoveries there included:

The Apries-1X, located in the Khalda Offset Concession within the Shushan Basin, tested 4,389 Bo/d and 14.2

MMcf/d from Paleozoic Basur sand. The well encountered 87 feet of net pay in the Basur.

The NTRK-H-1X, located in the North Tarek Concession within the Matruh Basin, tested 20 MMcf/d and 250

Bo/d from 60 feet of fracture-stimulated Jurassic Lower Safa pay. The well was a follow-up to the previously

announced NTRK-G-1X Upper Safa discovery.

Four horizontal wells were drilled during the quarter - the UMB 227H, NRQ 255-6H, MRZK 102H and Neama-14H.

The UMB 227H was drilled in the Upper Bahariya reservoir. A seven stage multi-frac completion is planned for Q2.

The NRQ 255-6H targeted the Abu Roash G dolomite and drilled 1,842 feet of lateral section. A total of 1,344 feet

of net pay was encountered, with an average porosity of 23 percent and water saturation of 37 percent. The well

is waiting on completion and will be acid stimulated. The MRZK 102H was completed with an initial rate of 1,030

Bo/d on February 13, and at the end of the first quarter, it was producing 880 Bo/d. Apache will start a multi-stage

fracture at the Neama-14H well in early May. Well results continue to highlight the potential of horizontal

technology in the Western Desert.

NORTH SEA KEY STATS First-Quarter 2014



Q1 Rigs: Avg 5 rigs

North Sea First-quarter production in the North Sea was 67,695 Boe/d, down

10 percent from the fourth quarter of 2013 due to a combination of

extended adverse weather offshore and unplanned downtime on

several platforms.

During the first quarter the region operated an average of five

drilling rigs and drilled four gross (three net) wells and conducted

two key workovers.

From the Forties Delta Platform, the T185 development well targeted by-passed oil identified on 4D time lapse

data which intersected 12 feet of true vertical depth net oil pay in the Upper Main Sand. The current rate after

two months of production is 1,000 Bo/d.

The Rowan Gorilla 7 heavy-duty jack up rig returned to the Forties field in February after extensive leg repairs and

started drilling operations on a three well program over Forties Echo.
