Exxon Mobil (XOM) says the shutdown of the Houston Ship Channel is affecting production rates at its huge Baytown refining complex, but the company does not disclose how large a drop it expects, only that it expects to meet its contractual obligations.
Tudor Pickering analysts say they don't think the spill will create a major energy event but a multi-day channel shutdown would have some effects on imports and inventories.
Companies aren't ready to detail potential problems: Valero (VLO), which has a refinery in Texas City, says it doesn't discuss refinery production rates, and Shell (RDS.A, RDS.B), which owns a refining and petrochemical complex in Deer Park near the Houston Ship Channel, says it has contingency plans in place to deal with a prolonged shutdown.
Phillips 66's (PSX) nearest refinery complex is in Sweeny, ~60 miles away from Houston, and gets most of its oil through waterways in Freeport; it doesn't foresee the spill affecting that plant's production.
The Coast Guard says there is no timetable on when the ship channel may reopen.
