Anadarko Petroleum Corporation ceased operating as an independent, publicly traded entity in August 2019 following its $55 billion acquisition by Occidental Petroleum Corporation (NYSE: OXY). News regarding former Anadarko assets, operations, legal liabilities, and midstream holdings is monitored through Occidental Petroleum’s financial disclosures, regulatory filings, and quarterly earnings reports.
Historical Corporate Context: The 2019 Acquisition War
Before its acquisition, Anadarko Petroleum Corporation was one of the largest independent oil and natural gas exploration and production (E&P) companies in the world. Headquartered in The Woodlands, Texas, Anadarko held a diverse portfolio spanning North American unconventional shale, deepwater Gulf of Mexico reserves, and international liquefied natural gas (LNG) developments.
In April 2019, Anadarko became the subject of one of the most intense bidding wars in modern energy history. Chevron Corporation initially reached an agreement to acquire Anadarko for approximately $33 billion in stock and cash ($65 per share), seeking to consolidate its position in the Permian Basin and deepwater assets.
However, Occidental Petroleum, led by Chief Executive Officer Vicki Hollub, launched a competing, unsolicited proposal valued at $76 per share (approximately $38 billion in equity value and an enterprise value of $55 billion including assumed debt).
| Date | 2019 Acquisition Timeline |
|---|---|
| April 12, 2019 | Chevron signs initial deal ($65/share) |
| April 24, 2019 | Occidental submits rival offer ($76/share) |
| April 30, 2019 | Berkshire Hathaway commits $10B preferred funding |
| May 5, 2019 | TotalEnergies agrees to buy African assets |
| May 9, 2019 | Chevron declines to match; collects $1B fee |
| August 8, 2019 | Occidental completes transaction; APC delisted |
To fund the high-cash portion of its offer without requiring an Occidental shareholder vote, Occidental secured two major financing agreements:
- Berkshire Hathaway Investment: Warren Buffett’s Berkshire Hathaway committed $10 billion in preferred equity, paying an 8% annual dividend, along with warrants to purchase Occidental common stock.
- TotalEnergies Asset Divestment: Occidental contracted to sell all of Anadarko’s African assets—including primary holdings in Mozambique and Ghana—to French energy major Total (now TotalEnergies) for $8.8 billion upon closing.
Chevron declined to increase its offer, choosing instead to collect a $1 billion breakup fee from Anadarko. Occidental officially completed the acquisition on August 8, 2019, and Anadarko’s ticker symbol (formerly NYSE: APC) was delisted.
Key Legacy Assets and Their Operational Status Today
Following the takeover, Occidental undertook a comprehensive integration process to assimilate Anadarko’s reserves while executing an aggressive debt-reduction strategy. Today, legacy Anadarko holdings form core operational pillars within Occidental's global enterprise.
Delaware Basin (Permian System)
Anadarko brought extensive, contiguous acreage in the Delaware Basin, a sub-basin of the Permian Basin in West Texas and Southeastern New Mexico. These holdings featured deep, multi-pay hydrocarbon zones ideal for horizontal drilling and hydraulic fracturing. Occidental combined these properties with its existing Permian acreage, establishing one of the largest combined positions in the play. The integration permitted shared surface infrastructure, optimized logistics, and reduced drilling and completion costs per lateral foot.
Deepwater Gulf of Mexico
Anadarko maintained significant deepwater production hubs in the Gulf of Mexico, including the Lucius, Heidelberg, and Constitution floating production facilities. These assets were characterized by low operational cash costs per barrel once infrastructure was established. Occidental retained these high-margin deepwater assets to generate consistent free cash flow, supporting ongoing dividend payments and corporate debt paydowns.
Wattenberg Field and DJ Basin (Colorado)
Anadarko was the primary acreage holder and operator in the Denver-Julesburg (DJ) Basin, centered in Weld County, Colorado. Operating in the DJ Basin introduced complex regulatory navigating points, including Colorado’s Senate Bill 19-181, which shifted local government oversight regarding well spacing, setbacks, and emissions rules. Occidental continues to manage these legacy DJ Basin wells under strict environmental standards enforced by the Colorado Energy and Carbon Management Commission (ECMC).
Midstream Infrastructure (Western Midstream Partners)
Anadarko operated as the sponsor and primary equity holder of Western Gas Partners, LP. Following the merger, Occidental assumed control of the general partner interest and significant limited partner units in the partnership, now known as Western Midstream Partners, LP (NYSE: WES). Occidental subsequently restructured its operating agreements with Western Midstream to establish operational independence for WES while retaining substantial ownership equity.
Environmental Liabilities and Legal Precedents
Any historical evaluation of Anadarko news includes its high-profile legal settlements and remediation commitments, which Occidental inherited upon closing the transaction.
The 2014 Tronox Settlement
In 2006, Anadarko acquired Kerr-McGee Corporation for $18 billion. Kerr-McGee had previously spun off its chemical division, Tronox, while transferring decades of legacy environmental liabilities—including radioactive waste, creosote contamination, and perchlorate pollution—to the newly formed company.
Tronox subsequently declared bankruptcy, and the federal government, alongside private plaintiffs, sued Anadarko, alleging the spin-off was a fraudulent conveyance designed to shield Kerr-McGee's valuable E&P assets from remediation liabilities.
In April 2014, Anadarko agreed to pay $5.15 billion to settle the litigation. It remains one of the largest environmental bankruptcy settlements in United States history, with roughly $4.4 billion dedicated directly to environmental cleanups handled by federal and state trusts.
| Tronox Settlement Breakdown | Details |
|---|---|
| Total Settlement Value | $5.15 Billion |
| Purpose | Fraudulent conveyance settlement |
| Environmental Trusts | ~$4.4 Billion for cleanup funding |
| Key Contaminants Covered | Radioactive waste, creosote, perchlorate contaminants |
Legacy Operational Liabilities
Occidental remains responsible for ongoing compliance, environmental remediation, and well-abandonment programs associated with historical Kerr-McGee and Anadarko facilities. Investors and regulatory bodies review these long-term liabilities through environmental accrual sections in Occidental’s financial reporting.

Frequently Asked Questions
Does Anadarko Petroleum still trade on the stock market?
No. Anadarko Petroleum Corporation (formerly NYSE: APC) was delisted from the New York Stock Exchange in August 2019 after Occidental Petroleum Corporation acquired all outstanding shares. Former shareholders received a combination of cash and Occidental stock based on the terms of the acquisition agreement.
What happened to Anadarko’s Mozambique LNG project?
Prior to completing the merger, Occidental reached an agreement to sell Anadarko’s African assets—including its interest in the massive Mozambique Area 1 Liquefied Natural Gas (LNG) project—to TotalEnergies for $8.8 billion. TotalEnergies took over operatorship of the Mozambique LNG project in late 2019.
How do I locate unclaimed stock or dividends from Anadarko?
If you held Anadarko stock prior to the 2019 acquisition and did not exchange your shares, contact Occidental’s transfer agent, Computershare, or search your state’s unclaimed property registry. Unclaimed buyout proceeds and historical uncashed dividends are periodically transferred to state escheatment offices under state abandoned property laws.
Who handles legal claims or royalty payments for old Anadarko mineral leases?
Occidental Petroleum handles mineral management, royalty distribution, and operational inquiries for active leases formerly held by Anadarko. Royalty owners can manage their accounts, update tax documents, or submit ownership transfers directly through Occidental's owner relations web portal.
Why did Chevron walk away from buying Anadarko in 2019?
Chevron declined to raise its $65-per-share offer after Occidental submitted a rival $76-per-share proposal. Chevron executives stated that increasing their offer would compromise capital discipline and lower return on capital employed (ROCE). Chevron formally terminated the agreement and collected a mandatory $1 billion termination fee from Anadarko.
Strategic Action Items for Investors and Royalty Holders
- For OXY Shareholders & Financial Analysts: Focus quarterly evaluations on Occidental Petroleum's consolidated debt-to-equity ratio, asset disposition reports, and capital expenditure allocation between deepwater projects and Permian Basin unconventional drilling.
- For Mineral & Royalty Rights Holders: Ensure all land records, division orders, and contact information are registered with Occidental's Royalty Owner Relations department to prevent payment holds or escheatment.
- For Historical Legal & Environmental Researchers: Consult historical court filings under In re Tronox Inc. for legal precedents on asset transfers and fraudulent conveyance liabilities, or inspect current state agency databases (Texas RRC, Colorado ECMC) for site-specific remediation tracking.
