DW is very big on Exxon’s value chain integration. So the strategy for a long time has been to keep / high grade refining assets that 1) provide a strategic outlet for upstream production and 2) are integrated with the lubes and Chemicals businesses (which have better margins and returns than the fuels business or 3) generate a lot of cash.
The refining portfolio of the future, then, is:
Baytown (Permian and Canadian crude consumption, lubes and chemicals)
Baton Rouge (same as Baytown)
Beaumont (huge capacity for Permian crude post-BLADE expansion, some chemicals)
Billings they’d love to sell as soon as they can find a buyer. Joliet at one point made a lot of $$ but it’s not a strategic asset and would be sold for the right price.
Strathcona makes a lot of $$ because of the Canadian crude disconnect so might keep it. Sarnia and nanticoke are not a strategic fit.
In EU, Antwerp and Rotterdam are strategic (lubes, chemicals, synergies across the sites, and they’re both high conversion with cokers and crackers so fairly well positioned vs. EU competition. Everyone else in EU will be sold / shut down (trecate, fos, Norway and Sicily both already sold). Fawley they had $1B plans to upgrade to make it more competitive but not clear that project will go now. Without that investment, Fawley doesn’t have a place in the refining portfolio. Gravenchon has chemicals and is integrated with the other NWE assets in some feedstock and value chains … but it’s a marginal asset.
In Asia, altona is shutting down. Thailand is not strategic. the chemicals portion of that plant is old and not profitable and was shut down in 2020, and the Thailand fuels market is nothing special. Singapore is strategic but it’s not a competitive asset and it desperately needs the CRISP project to be more durable. Parts of the chemical plant in Singapore are strong, but other parts are not competitive so some selective shutdowns are likely (some have already happened on a temporary basis, just need to make them permanent).
The JV refinery in Saudi has good cash generation. Miro in Germany I’m sure they’d love to cash out. Fujian will stay.
Similar to Shell, look for the portfolio to continue to shrink, with a focus on a few complex, integrated sites in the key markets (USGC, NWE, Singapore), and the odd site here or there than isn’t strategic but has good cash Gen.
The decline from >40 refineries a few decades ago to <20 today and rapidly declining has been painful to watch. And it tells you a lot about what life in refining is going to be like in the future.
