INEOS, the controversial company behind the sprawling Grangemouth petrochemicals plant, has acquired a majority stake in two oil and gas exploration licences west of Shetland.

The company, which recently completed its acquisition of the giant Forties North Sea pipeline, said the licences in the Northern Gas Fields are among the most exciting prospects in British offshore waters.

It builds on the company’s growing portfolio of oil-producing assets West of Shetland, including interests recently acquired from DONG E&P.

The latest acquisitions means Ineos now has positions in the four fields which make up the Northern Gas Fields' Lyon cluster - Lyon, Tobermory, Bunnehaven and Cragganmore.

Geir Tuft, chief executive of Ineos Oil & Gas, said: “INEOS intends to become a significant player in this area.  This deal confirms our aim to take a leading role to develop the Northern Gas Fields using the significant infrastructure investments already made West of Shetland.” 

Ineos has attracted controversy in recent years over its support for fracking.
