London: Global law firm Clifford Chance has advised Harbour Energy on the acquisition of a portfolio of assets belonging to natural gas and oil company Wintershall Dea from BASF and LetterOne. The attributed value to the acquisition is US$11.2 billion.

The portfolio of assets includes all of Wintershall Dea’s upstream assets in Norway, Germany, Denmark Argentina, Mexico, Egypt, Libya and Algeria as well as its CO2 Capture and Storage (CCS) licences in Europe. Wintershall Dea’s Russian assets are excluded.

The acquisition is expected to transform Harbour Energy into one of the world’s largest and most geographically diverse independent oil and gas companies, adding material gas-weighted portfolios in Norway and Argentina and complementary growth projects in Mexico. Harbour will also benefit from an increased reserve life and improved margins with lower operating costs and greenhouse gas (“GHG”) intensity.
