Exhibit 99.1

NEWS RELEASE

APACHE CORPORATION ANNOUNCES THIRD-QUARTER 2019

FINANCIAL AND OPERATIONAL RESULTS

• Reported third-quarter production of 451,000 barrels of oil equivalent (BOE) per day. Adjusted production, which excludes Egypt noncontrolling interest and tax barrels, was 391,000 BOE per day, exceedingupper-end guidance of 383,000 BOE per day;

• Achieved U.S. production of 266,000 BOE per day, which exceedsupper-end guidance of 260,000 BOE per day; international adjusted production was 125,000 BOE per day, slightly ahead of guidance;

• Invested $590 million in upstream capital; remain on track for $2.4 billion for the year;

• Nearing first production from two new high-volume North Sea wells;

• Drilling first well in Block 58 offshore Suriname; expected to reach total depth in November; and

• Announced organizational initiatives targeting operational efficiencies and annual cost savings of at least $150 million.

HOUSTON, Oct. 30, 2019 – Apache Corporation (NYSE, Nasdaq: APA) today announced its financial and operational results for the third quarter of 2019.

Apache reported a quarterly loss of $170 million or $0.45 per diluted common share for the third quarter of 2019. These results include a number of items outside of core earnings that are typically excluded by the investment community in their published earnings estimates. When adjusted for items that impact the comparability of results, Apache reported a third-quarter loss of $108 million or $0.29 per share. Adjusted earnings were generally in line with expectations except for the impact of increased depreciation, depletion and amortization costs. This was primarily associated with a reduction in Alpine High reserves due to deteriorating natural gas liquids (NGL) and gas prices. Upstream oil and gas capital investment was $590 million in the third quarter. Net cash provided by operating activities in the quarter was $635 million and adjusted EBITDAX was $905 million.

“During the third quarter, adjusted production exceeded guidance while capital expenditures remained on pace with our full-year guidance of $2.4 billion,” said Apache CEO and President John Christmann. “In September, we began drilling the first of three committed wells in Block 58 offshore Suriname. We are also nearing first production from two wells in the North Sea, which should establish strong production momentum as we enter 2020.”

Third-Quarter Operational Summary

Highlights from the company’s principal areas include:

Permian – Production averaged 254,000 BOE per day during the quarter and Apache operated an average of 10 rigs and drilled and completed 47 gross-operated wells. In the Permian Basin, our oil production in the second half of the year has been modestly impacted by some unplanned downtime events and completion schedule delays. As a result, the company is now projecting fourth-quarter Permian oil volumes of approximately 100,000 barrels per day.

• Midland Basin– During the quarter, the company averaged three rigs and placed 22 wells on production. Good results from a Lower Cline test well in the Azalea Field will lead to further evaluation and potential expansion of Apache’s core development inventory.

• Delaware Basin– Outside of Alpine High in the Delaware Basin, Apache averaged two rigs and placed nine wells on production during the quarter.

Production at Alpine High averaged 76,000 BOE per day for the quarter and the company averaged five rigs and one frac crew and placed 15 wells on production. Volumes previously deferred due to low Waha prices were returned to production during August and September.

As a result of continued weakness in gas and NGL pricing, the company has reduced Alpine High drilling activity to two rigs and has chosen to defer some fourth-quarter completions into 2020. These changes, combined with a reduced production outlook for a recent multiwell pad, has resulted in a 5% decrease in fourth-quarter Alpine High production guidance.

Egypt– Apache averaged seven rigs during the quarter and drilled and completed 14 gross-operated wells. Adjusted production in Egypt, which excludes noncontrolling interest and the impact of tax barrels, averaged 72,000 BOE per day, up slightly from the second quarter. The company drilled multiple successful exploration wells during the quarter that have positive implications for future development inventory.

North Sea – Apache averaged three rigs during the quarter and produced 54,000 BOE per day, which reflects an anticipated decrease related to seasonal platform maintenance. The company expects to bring its first well at Storr online in November and its second well at Garten online aroundyear-end. The Garten well encountered approximately 1,200 feet of pay, which significantly exceeded the company’spre-drill estimates.

Suriname – Apache is currently drilling theMaka Central #1 well and expects to reach total depth in November at approximately 6,325 meters as measured from the deck of the drillship. The well is designed to test multiple targets and is located roughly seven miles from the Suriname / Guyana maritime border. Apache also exercised its option to drill two additional wells in Suriname Block 58 with the Noble Sam Croft drillship.

Organizational and Cost Saving Initiatives

“Apache has historically employed a decentralized, region-focused approach to operations. In recent years, we have centralized certain key activities, and today we see an opportunity to capture greater efficiencies by taking further steps in that direction,” continued Christmann. “To accomplish this, we have initiated a comprehensive redesign of our organizational structure and operations that will position us to be competitive for the long term. This process, which began in late summer, should be largely completed by the end of the first quarter 2020. We are targeting at least $150 million of combined annual savings and look forward to updating you on our progress in the future.”

Closing

“Our primary objectives are to deliver competitive, risk-adjusted returns with a long-term moderate pace of growth and improve our free cash flow yield to levels consistent with other mature industrial sectors. As we look to 2020, based on current strip prices, we anticipate our upstream capital budget will be 10% to 20% below this year’s program of $2.4 billion. This will enable us to generate organic free cash flow that covers the current dividend and puts us on pace to fund a multiyear debt reduction program, while also delivering modest year-over-year oil production growth. We look forward to sharing the details of our 2020 capital plan in February,” concluded Christmann.

made by us that we believe to be reasonable under the circumstances, whether actual results and developments will meet our expectations and predictions depend on a number of risks and uncertainties which could cause our actual results, performance, and financial condition to differ materially from our expectations. See “Risk Factors” in our 2018 Form10-K and in our quarterly reports on Form10-Q filed with the U.S. Securities and Exchange Commission (“SEC”) for a discussion of risk factors that affect our business. Any forward-looking statement made by us in this news release speaks only as of the date on which it is made.

Cautionary note to investors

The 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 release, such as “resources,” “potential resources,” “resource potential,” “estimated net reserves,” “recoverable reserves,” 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 Form10-K for the fiscal year ended Dec. 31, 2018, available from Apache atwww.apachecorp.com or by writing Apache at: 2000 Post Oak Blvd., Suite 100, Houston, TX 77056 (Attn: Corporate Secretary). You can also obtain this report from the SEC by calling1-800-SEC-0330 or from the SEC’s website atwww.sec.gov.

NON-GAAP FINANCIAL MEASURES

(In millions, except per share data)

Reconciliation of Net cash provided by operating activities to Adjusted EBITDAX

Management believes EBITDAX, or earnings before income tax expense, interest expense, depreciation, amortization and exploration expense is a widely accepted financial indicator, and useful for investors, to assess a company’s ability to incur and service debt, fund capital expenditures, and make distributions to shareholders. We define adjusted EBITDAX, anon-GAAP financial measure, as EBITDAX adjusted for certain items presented in the accompanying reconciliation. Management uses adjusted EBITDAX to evaluate our ability to fund our capital expenditures, debt services and other operational requirements and to compare our results from period to period by eliminating the impact of certain items that management does not consider to be representative of the Company’son-going operations. Management also believes adjusted EBITDAX facilitates investors and analysts in evaluating and comparing EBITDAX from period to period by eliminating differences caused by the existence and timing of certain operating expenses that would not otherwise be apparent on a GAAP basis. However, our presentation of adjusted EBITDAX may not be comparable to similar measures of other companies in our industry.

Reconciliation of Income attributable to common stock to Adjusted earnings

Our presentation of adjusted earnings and adjusted earnings per share arenon-GAAP measures because they exclude the effect of certain items included in Income Attributable to Common Stock. Management believes that adjusted earnings and adjusted earnings per share provides relevant and useful information, which is widely used by analysts, investors and competitors in our industry as well as by our management in assessing the Company’s operational trends and comparability of results to our peers.

Management uses adjusted earnings and adjusted earnings per share to evaluate our operating and financial performance because it eliminates the impact of certain items that management does not consider to be representative of the Company’son-going business operations. As a performance measure, adjusted earnings may be useful to investors in facilitating comparisons to others in the Company’s industry because certain items can vary substantially in the oil and gas industry from company to company depending upon accounting methods, book value of assets, capital structure and asset sales and other divestitures, among other factors. Management believes excluding these items facilitates investors and analysts in evaluating and comparing the underlying operating and financial performance of our business from period to period by eliminating differences caused by the existence and timing of certain expense and income items that would not otherwise be apparent on a GAAP basis. However, our presentation of adjusted earnings and adjusted earnings per share may not be comparable to similar measures of other companies in our industry.

NON-GAAP FINANCIAL MEASURES

(In millions)

Reconciliation of Debt to Net debt

Net debt, or outstanding debt obligations less cash and cash equivalents, is anon-GAAP financial measure. Management uses net debt as a measure of the Company’s outstanding debt obligations that would not be readily satisfied by its cash and cash equivalents on hand.

Reconciliation of Costs incurred to Upstream capital investment

Management believes the presentation of upstream capital investments is useful for investors to assess Apache’s expenditures related to our upstream capital activity. We define capital investments as costs incurred for oil and gas activities, adjusted to exclude asset retirement obligation revisions and liabilities incurred, capitalized interest, and certain exploration expenses, while including amounts paid during the period for abandonment and decommissioning expenditures. Upstream capital expenditures attributable to aone-third noncontrolling interest in Egypt are also excluded. Management believes this provides a more accurate reflection of Apache’s cash expenditures related to upstream capital activity and is consistent with how we plan our capital budget.

Reconciliation of Net cash provided by operating activities to Cash flows from operations before changes in operating assets and liabilities

Cash flows from operations before changes in operating assets and liabilities is anon-GAAP financial measure. Apache uses it internally and provides the information because management believes it is useful for investors and widely accepted by those following the oil and gas industry as a financial indicator of a company’s ability to generate cash to internally fund exploration and development activities, fund dividend programs, and service debt. It is also used by research analysts to value and compare oil and gas exploration and production companies and is frequently included in published research when providing investment recommendations. Cash flows from operations before changes in operating assets and liabilities, therefore, is an additional measure of liquidity but is not a measure of financial performance under GAAP and should not be considered as an alternative to cash flows from operating, investing, or financing activities.
