Overview
Harbour Energy plc is a United Kingdom-based independent oil and gas company headquartered in London. Its business is concentrated on the exploration, development and production of hydrocarbons, with a portfolio that has historically been anchored in the UK North Sea and has expanded through acquisitions and international projects. The company operates or holds interests in assets in the United Kingdom, South America, Mexico, Norway, Africa and Indonesia. Harbour was established in July 2014 through the backing of commodity trader Noble Group and private-equity investor EIG Global Energy Partners. The initial funding consisted of US$150 million from Noble Group and US$50 million from EIG. Rather than beginning as a conventional exploration venture, the company was structured to provide financial support for acquisitions of producing and development assets. Its early strategy centered on Chrysaor Holdings, an oil and gas company that acquired a substantial portfolio of assets from Royal Dutch Shell. Harbour's financial backing made it Chrysaor's largest shareholder and gave Harbour exposure to a large, mature North Sea production base. A major expansion occurred in 2020 and 2021. In June 2020, Harbour backed Chrysaor's proposed acquisition of Premier Oil. The transaction was completed through a merger in 2021, bringing Chrysaor and Premier Oil together under the Harbour Energy name. The combined business was managed by Linda Cook, who had served as Harbour's chief executive since the company's creation. The merger created what was described as the United Kingdom's largest independent oil and gas business, strengthening Harbour's position in UK upstream production while adding Premier's international and development interests. The company has also pursued selective international growth and large-scale development projects. In Indonesia, Harbour operates the Tuna offshore gas field, for which the country's oil and gas regulator approved a plan of development in 2023. The project was expected to involve investment of approximately US$3 billion. Harbour is also involved in planning the Viking CCS project in the Humber region. The proposed system is designed to collect carbon dioxide from industrial sources, transport it to the North Sea and store it in depleted offshore gas fields, linking Harbour's subsurface and offshore capabilities with industrial decarbonization infrastructure. In December 2023, Harbour agreed to acquire the upstream business of Wintershall Dea from BASF and LetterOne for approximately US$11.2 billion. The transaction significantly expanded Harbour's international portfolio and was completed in the fourth quarter of 2024. BASF and LetterOne received Harbour shares as consideration, resulting in the sellers holding substantial equity stakes. The acquisition marked a strategic shift for Harbour from a predominantly UK-focused independent producer to a broader international oil and gas group. Harbour's principal products are not consumer goods but crude oil, natural gas, condensate and related upstream services and production activities. Its commercial identity is therefore based on the operation and investment of oil and gas fields, the management of mature assets, the advancement of offshore developments and participation in infrastructure-intensive projects such as carbon capture and storage. As a listed company, Harbour combines private-equity-influenced acquisition discipline with public-market reporting and exposure to commodity prices, production performance, regulation and the energy transition. Its current positioning is as an international independent upstream company with a portfolio spanning conventional hydrocarbon production and emerging carbon management infrastructure.
History
Harbour Energy was created in July 2014 by Noble Group and EIG Global Energy Partners. The sponsors supplied initial capital of US$150 million and US$50 million respectively. The company was designed as an investment-backed upstream vehicle and provided financial support to Chrysaor Holdings, enabling Chrysaor to purchase oil and gas assets valued at approximately US$3.8 billion from Royal Dutch Shell. Harbour consequently became Chrysaor's largest shareholder and gained exposure to a substantial portfolio of producing and development assets, particularly in the UK North Sea. The next major stage came in 2020, when Harbour backed Chrysaor's proposed acquisition of Premier Oil. The combination was completed in 2021 through the merger of Chrysaor Holdings and Premier Oil, with both businesses brought together under the Harbour Energy identity. Linda Cook, who had been Harbour's chief executive since its establishment, was announced as the leader of the combined company. The transaction created what was described as the UK's largest independent oil and gas business and expanded the group's asset base, production profile and international reach. Harbour continued to develop assets outside the United Kingdom. In 2023, Indonesia's oil and gas regulator, SKK Migas, approved the first plan of development for the Tuna offshore gas field, operated by Harbour. The development carried an estimated total investment of approximately US$3 billion. Harbour has also been associated with the Viking Carbon Capture and Storage project in the Humber area. The project, developed with BP as a partner, is intended to capture carbon dioxide from industrial sources, transport it offshore and store it in depleted North Sea gas fields. Proposed sources include the VPI power station and the Phillips 66 Humber refinery. The project was planned with a target of beginning operations in 2028 and a prospective storage capacity described in the tens of millions of tonnes of carbon dioxide per year. In December 2023, Harbour agreed to acquire Wintershall Dea's oil and gas production business from BASF and LetterOne for approximately US$11.2 billion. The transaction was completed in the fourth quarter of 2024. Rather than paying entirely in cash, Harbour issued shares to the sellers; BASF received 39.6 percent and LetterOne 14.9 percent of Harbour according to the referenced account. The deal transformed Harbour from a company centered primarily on UK North Sea assets into a larger international upstream group with operations and interests across several regions. The company has also pursued further portfolio expansion. In December 2025, Harbour was reported to have agreed to acquire subsidiaries of Waldorf Energy Partners and Waldorf Production for approximately US$170 million, with completion expected in 2026. The proposed purchase would increase Harbour's interest in the Catcher oil field to 90 percent and add a 29.5 percent non-operated interest in the Kraken field in the North Sea. Together, these transactions illustrate Harbour's recurring strategy: acquire or combine with established upstream portfolios, operate mature fields efficiently, and selectively advance new offshore developments. Its history has therefore been shaped more by mergers, asset purchases and portfolio consolidation than by organic exploration alone.

Products and positioning
Independent upstream oil and gas producer focused on acquiring, operating and developing producing and development assets, with additional participation in carbon capture and storage infrastructure.
Hydrocarbon production
Crude oil
Crude oil is one of Harbour Energy's principal upstream outputs. The company produces and markets oil from operated and non-operated fields, particularly in the UK North Sea and other international asset areas. Its oil business is tied to field operations, reservoir management, offshore infrastructure and development planning rather than to consumer-facing branded fuels.
Hydrocarbon production
Natural gas
Natural gas is a major component of Harbour's upstream portfolio. The company develops and produces gas through offshore projects including the Tuna field in Indonesia, while also holding gas interests in the UK and other regions. Gas production supports Harbour's role as an upstream supplier but remains exposed to commodity prices, infrastructure availability and regulatory requirements.
Hydrocarbon production
Condensate
Condensate and associated liquids may be recovered alongside gas production from Harbour's upstream assets. These outputs are handled as part of field production and commercialization rather than as separately marketed consumer products.
Carbon management infrastructure
Viking Carbon Capture and Storage
Viking CCS is a proposed carbon capture and storage system led by Harbour Energy with BP as a partner. It is designed to collect carbon dioxide from industrial facilities in the Humber region, compress and transport it, and store it in depleted offshore gas fields beneath the North Sea. The project connects Harbour's offshore subsurface expertise with industrial decarbonization and was planned for potential operations from 2028.
Controversies
2026
Wood Group offshore workers launch 48-hour strike over pay and conditions
Offshore production, instrument and mechanical technicians on several North Sea platforms began a 48-hour strike at midnight on 6 October 2026 in a dispute with Wood Group over pay and conditions. Further walkouts were planned for 20-21 October and 3-4 November, and an RMT overtime ban was instructed from 8 October. The Unite and RMT unions said the dispute concerned Wood Group's decision to cut the pay and conditions of dozens of offshore workers, including through the threat of fire-and-rehire notices. The strikes affect installations run by Harbour Energy, including the Britannia, Jasmine, Judy, Lomond and North Everest platforms. Wood Group said it had been notified of the action and that personnel and operational safety remain its top priority.
