NEW YORK (TheStreet) -- Shares of Oasis Petroleum (OAS) - Get Report are falling 7.5% to $7.28 in midday trading Wednesday as oil prices hit a two-month low after U.S. data showed an unexpected rise in crude and gasoline inventories.

Crude oil (WTI) is retreating 2.26% to $41.95 per barrel and Brent crude is sinking 2.63% to $43.69 per barrel this afternoon.

The Energy Information Administration said domestic crude stocks increased by 1.7 million barrels, while analysts were expecting a decline of 2.3 million barrels, Reuters reports.

"A drop in refinery runs at the peak of summer driving season indicate refiners are dialing back amid faltering profit margins," Matt Smith, an analyst at oil cargoes tracker Clipperdata, told Reuters.

Oasis Petroleum is a Houston-based exploration and production company.

Separately, TheStreet Ratings Team has a "Sell" rating with a score of D on the stock.
