NEW YORK (TheStreet) -- Marathon Oil Corp. (MRO - Get Report)  shares are declining 0.14% to $7.38 on Wednesday along with tumbling oil prices. 

Crude oil (WTI) is tumbling 1.83% to $27.43 per barrel and Brent crude is gaining 1.48% to $30.77 per barrel.

Even though the U.S. Energy Information Administration released a report showing that crude inventories declined by 754,000 barrels last week, compared to expectations of an increase of 3.6 million barrels, the data was offset by persisting oversupply concerns.

"Since we are going into refinery maintenance season and coupled with Iranian oil coming into the market, any rally will be short-lived," Tyche Capital Advisors crude oil trader Tariq Zahir told
