Shell plans to reduce its refinery portfolio to six sites from 14 by 2025, the company said on Thursday.

The six sites will be in Deer Park, Texas, US; Norco, Louisiana, US; Pernis, the Netherlands; Pulau Bukom, Singapore; Rheinland, Germany; and Scotford, Canada.

The refineries will become integrated with chemicals and increasingly with low-carbon fuels such as biofuels, hydrogen and synthetic fuels, said Ben van Beurden, CEO.

As far as the eight other refineries, Shell is already in the process of divesting some of them, said Curtis Smith, spokesman. Other options include converting them into terminals or closing them.

The other refineries include those in Frederica, Denmark; Puget Sound, Washington, US; Mobile, Alabama, US; Convent, Louisiana, US; and Sarnia, Ontario, Canada.
