Shares of fuel producers are set to trade on high volume this week with 12% of the U.S.'s refining capacity shuttered as fuel makers along the Texas coast assess damage from Hurricane Harvey, according to Goldman Sachs economists.

More than 2 million barrels of refining capacity has been shut in because of Harvey, which was downgraded to a tropical storm after hitting as a category 4 hurricane. Based on data from similar storms in the past, Goldman estimates that Harvey will increase domestic crude availability by about 1.4 million bpd due to refinery shut-ins. Gasoline supplies will drop by 615,000 to 785,000 bpd and distillate supplies will drop by 700,000 bpd, though.

Goldman noted that ExxonMobil (XOM) , Royal Dutch Shell (RDS.A) , Phillips 66 (PSX) , Valero (VLO) and Marathon Petroleum (MPC) all reduced output or shut refineries as Harvey approached.

Refiner margins are due for a boost as "non-affected refiners [are incentivized] to operate at higher utilization," Goldman wrote. Economists don't forecast much impact on refiners' normalized view of earnings or valuation based on 2018 estimates.

Goldman keeps a "buy" rating and "Conviction List" tag on Andeavor (ANDV) and maintains "buy" ratings on Marathon and Delek US Holdings Inc. (DK) .
