In December 2024, INEOS Energy acquisitioned the Gulf of Mexico deepwater assets of CNOOC Energy Holidays USA Inc., a subsidiary of CNOOC International Ltd, marking the third major investment for INEOS within the US in the last three years.

The deal includes the acquisition of non-operated assets built around two deepwater early production assets within the Gulf (Appomattox and Stampeded fields), as well as several mature assets and supporting businesses. The additional asset increase INEOS global production rate to more than 90,000 barrels of oil equivalent per day.

Brian Gilvary, Chairman of INEOS Energy, said, “This is a major step for us into the deepwater Gulf of Mexico, which builds on our growing energy business. INEOS Energy is all about competing in the energy transition to provide reliable, affordable energy to meet world demands as the population continues to grow.”

INEOS Energy’s CEO, David Bucknall, added, “The USA is a very attractive place for INEOS Energy to invest. This is our third deal in three years following the 1.4 mtpa LNG deal with Sempra and the acquisition of Chesapeake Energy’s oil and gas assets in South Texas. Total capital spend on energy assets in the USA now exceeds US$3bn, providing a strong platform for future growth.”
