Harbour Energy plc

Harbour Energy was founded in 2014 by EIG Global Energy Partners to build an independent oil and gas company through acquisitions. It became a publicly listed company in 2021 through the reverse takeover of Premier Oil, then substantially expanded through the 2024 acquisition of Wintershall Dea’s upstream portfolio and its February 2026 entry into the US Gulf of America through LLOG Exploration.

The company explores, develops and operates oil and gas assets across 10 countries, with significant positions in Norway, the UK, Argentina, Germany, Mexico and the US Gulf. Its portfolio combines producing assets with development projects and is deliberately diversified: no single production hub accounts for more than 10% of output.

Harbour is particularly strong in acquisition integration, operated upstream assets and portfolio diversification. It also has a significant carbon-capture and storage position in Europe, while projects such as Mexico’s Zama field and Argentina’s Southern Energy LNG project provide longer-term growth opportunities.
