Amplify Energy
Amplify Energy is a Houston-based independent U.S. oil and natural gas exploration and production company.
Last updated August 31, 2026
Overview
Amplify Energy Corp. is an independent American upstream oil and natural gas company headquartered in Houston, Texas. Its business is focused on the exploration, development, production, and operation of crude-oil and natural-gas assets rather than on refining, fuel retailing, or other consumer energy activities. The company has operated a mixed portfolio of onshore and offshore properties in the United States, producing crude oil, natural gas, and natural-gas liquids from fields and infrastructure that it owns or manages. Amplify was formed in 2017 as the successor to Memorial Production Partners, a publicly traded master limited partnership that entered Chapter 11 bankruptcy protection that year. The restructuring substantially reduced Memorial’s debt and created the platform that became Amplify Energy. In 2019, Amplify merged with Midstates Petroleum, another U.S. exploration and production company that had previously undergone bankruptcy proceedings. That transaction expanded the company’s asset base and operating footprint and helped establish its portfolio-oriented model, combining mature producing properties with opportunities for operational improvement and selective development. The company’s assets have included oil and gas wells in Texas, Oklahoma, Wyoming, and other western U.S. areas, as well as offshore production infrastructure in Southern California. Its Beta Offshore subsidiary has operated the Beta field, a group of offshore platforms near the Los Angeles area. The field’s facilities include the Elly, Ellen, and Eureka platforms and associated subsea and shore-connected pipeline infrastructure. The offshore system separates produced fluids and transports oil toward the Port of Long Beach. Amplify’s onshore activities have included hydraulic fracturing and, in some fields, water or carbon-dioxide injection and brine-water management. These techniques expose the company to the ordinary operational, environmental, regulatory, commodity-price, and infrastructure risks associated with independent oil and gas production. Amplify’s most prominent public controversy was the October 2021 Southern California oil spill. Oil reached beaches and wetlands around Huntington Beach and Newport Beach, prompting an emergency response, wildlife impacts, investigations, litigation and extensive scrutiny of the company’s pipeline operations and reporting practices. Investigators later examined whether anchor dragging by commercial vessels during an earlier storm had displaced and damaged the subsea pipeline. In 2022, Amplify announced a proposed agreement under which it would plead guilty to a misdemeanor negligent-discharge charge, pay approximately $7 million in penalties over three years, reimburse nearly $6 million to government agencies, and install an upgraded leak-detection system, subject to court approval. Amplify has also faced periodic financial and capital-market pressures typical of smaller independent producers. In 2020, the New York Stock Exchange notified the company that its share price created a potential listing-compliance issue; the company subsequently regained compliance. During the COVID-19 downturn, it disclosed receipt of approximately $5.5 million in Paycheck Protection Program financing, generating public debate because it was a publicly traded company that had also undertaken share repurchases. The company’s stock trades on the New York Stock Exchange under the symbol AMPY. Amplify remains an upstream energy operator whose performance depends heavily on production volumes, realized oil and gas prices, reserve quality, financing access, environmental compliance, and the safe operation of its wells, platforms, and pipelines.
History
Amplify Energy was established in 2017 as the successor to Memorial Production Partners, an oil and gas partnership that entered Chapter 11 bankruptcy protection. Memorial’s restructuring reduced its debt from approximately $1.3 billion to about $430 million and created the financial and operating foundation for the new company. Amplify continued the upstream model of owning or operating producing oil and natural-gas properties and sought to manage a portfolio of mature and developable U.S. assets. The company’s management changed in May 2018 when Ken Mariani, formerly associated with EnerVest, became chief executive officer. In 2019, Amplify combined with Midstates Petroleum, a Tulsa-based producer that had itself undergone bankruptcy proceedings in 2016. The transaction broadened Amplify’s geographic and operational footprint. The company subsequently operated roughly 1,000 oil wells and 1,500 natural-gas wells across assets in Texas and western states, although the exact portfolio and well count have changed over time. Its field operations have used hydraulic fracturing in many wells, along with injection methods such as carbon dioxide, water, and brine-water disposal in selected producing areas. Such operations have required regulatory permits and have exposed the company to scrutiny concerning wastewater management and induced seismicity. Amplify also owns and operates offshore infrastructure through its Beta Offshore subsidiary. The Beta field lies off the Southern California coast near Los Angeles and includes the Elly, Ellen, and Eureka platforms. Production from the field is gathered and processed offshore, with oil transported through a subsea pipeline system toward the Port of Long Beach. The platforms and pipeline represent a materially different operating environment from the company’s onshore wells: offshore production involves marine safety, pipeline integrity, environmental response, and federal and state regulatory obligations. The Beta field itself has a long history predating Amplify, having originally been discovered by Royal Dutch Shell in 1976. The nearby Huntington Beach field also has a much older production history, dating to its discovery by Standard Oil in 1920. Amplify’s capital and governance history during the late 2010s and early 2020s reflected the pressures facing smaller independent producers. In 2018 and 2019 it authorized and completed share repurchases, while it also paid dividends and maintained a revolving credit facility. The company’s 2019 revenue and financing position were affected by commodity-market conditions, and the COVID-19 pandemic created additional liquidity and demand concerns. In April 2020, the NYSE warned that the company’s share price could lead to delisting; Amplify restored compliance by June. Mariani announced his retirement in April 2020, after which CFO Martyn Willsher became interim CEO. The company also disclosed a $5.5 million Paycheck Protection Program loan, a decision that attracted media and public attention because Amplify was publicly listed and had recently undertaken stock repurchases. The defining event in Amplify’s public history was the October 2021 oil spill off Southern California. Oil and oiled wildlife reached beaches and wetlands around Huntington Beach and Newport Beach. Initial volume estimates were later revised and remained contested in public reporting. The National Transportation Safety Board and other authorities investigated the cause and the company’s response. Coast Guard investigators reported that a commercial vessel had dragged an anchor during severe weather in January 2021 and that the pipeline appeared to have been displaced by roughly 100 feet and suffered damage to its concrete casing. Investigators also considered the role of a second vessel. The pipeline had reportedly been intact during an inspection in 2020, while marine growth around the displaced portion suggested that the damage was not recent. The incident generated criticism over the timing of notification to federal regulators, the adequacy of pipeline monitoring, and the company’s public communications. Cleanup, wildlife response, government investigations, civil claims, and criminal proceedings followed. In August 2022, Amplify announced a proposed resolution involving a guilty plea to one misdemeanor count of negligent oil discharge, approximately $7 million in fines over three years, almost $6 million in reimbursements to government agencies, and installation of an improved leak-detection system, subject to judicial approval. In March 2024, another offshore oil sheen was observed near Huntington Beach. Amplify stated that it had no indication the sheen was related to its operations and offered cooperation to responders. Testing reportedly found that sampled oil was consistent with natural seep material, although authorities did not conclusively determine the source. Amplify continues to operate as a publicly traded independent producer, with its business subject to commodity prices, reserve performance, financing conditions, environmental regulation, and the integrity of its onshore and offshore infrastructure.

Products and positioning
Independent U.S. upstream oil and natural gas exploration and production company
Crude oilUpstream energy product
Crude oil is one of Amplify Energy’s principal outputs. It is produced from the company’s U.S. oil fields, including onshore properties and the offshore Beta field near Southern California. Amplify’s role is primarily exploration, development, production, field operation, processing, and transportation through associated infrastructure rather than consumer fuel marketing or refining.
Natural gasUpstream energy product
Natural gas is produced from Amplify’s U.S. onshore and other oil and gas assets. It forms part of the company’s upstream hydrocarbon portfolio and is marketed through commercial arrangements rather than sold under a consumer-facing retail brand. Gas production may also support field operations where it is processed or used as part of production infrastructure.
Natural gas liquidsUpstream energy product
Natural gas liquids are associated hydrocarbon products recovered from some natural-gas production. They complement Amplify’s crude-oil and gas output and contribute to the value of its producing assets. The company’s business is the upstream production and sale of these hydrocarbons, not the manufacture of branded specialty products.
