Harbour Energy was founded by private equity firm EIG Global Energy Partners in 2014 with a goal to build a new, global independent oil and gas company through acquisition of cash generative, producing assets, with an initial focus outside of North America.
In 2017, Harbour Energy made its first acquisition by acquiring Chrysaor Holdings Limited and, through it, a package of UK North Sea assets from Shell for $3.0 billion. This was followed in 2019 with the acquisition of ConocoPhillips UK North Sea for $2.7 billion, making the company the UK’s largest oil and gas producer.
In 2021, through a reverse takeover, Chrysaor merged with Premier Oil to create Harbour Energy plc. Premier Oil added complementary assets in the UK, provided a starting point for future international diversification with assets in South East Asia and Mexico, delivered material financial synergies, and resulted in Harbour securing a UK public listing.
In late 2023, Harbour Energy announced the acquisition of substantially all of the upstream assets of Wintershall Dea. The transaction completed in September 2024, adding material positions in Norway, Germany, Argentina, Mexico and North Africa and transforming Harbour Energy into one of the world’s largest and most global independent oil and gas companies.
