It appears that Netherlands-based Royal Dutch Shell
Shell and its Saudi Aramco partner, the principals in Motiva Enterprises, which owns a Port Arthur refinery with a current 275,000 barrels-per-day capacity, will spend about $7 billion and three years to expand the facility to a capacity near 600,000 bpd. This will make the facility the U.S.'s largest, besting ExxonMobil's
There are currently no meaningful plans to initiate construction of new refineries in the U.S. In fact, I doubt the public would permit it. A constant Not in My Backyard (NIMBY) mentality renders it OK to drill for hydrocarbons or build refineries in someone else's area, but no one wants that activity near their own towns. For that reason, and especially in the face of capacity shortages in the U.S., it'll be interesting to observe how the refinery scene changes, or fails to do so, in the years ahead.
