Pioneer Natural Resources (NYSE:PXD) CEO Scott Sheffield is the most recent domestic energy producer to clamor for allowing crude oil exports from the United States. According to a recent Platts article, Sheffield said a failure to open up exports could have a negative consequence on the U.S. drilling rig market, leading to a possible domestic crude price $30 less than international prices. While a glut of oil could temporarily lead to a widening WTI-Brent crude spread, the $30 spread Sheffield mentioned is unlikely. Yes, the spread reached $30 in 2011, but increased crude-by-rail transportation, the reversal of the Seaway pipeline, and additional takeaway capacity should keep the crude spread much closer.
