NEW YORK (TheStreet) -- Shares of Oasis Petroleum (OAS) - Get Report were trading higher late Thursday afternoon as an uptick in oil prices benefits the Houston-based oil and gas producer. 

Crude oil (WTI) was increasing 1.33% to $47.39 per barrel while Brent crude was climbing 1.41% to $49.74 per barrel earlier today. 

Oil prices are up on speculation that the dollar will weaken after tomorrow's monetary policy speech by Federal Reserve Chairwoman Janet Yellen. 

Citigroup noted that asset managers expect the central bank to raise interest rates once this year and then slowly tighten monetary policy, Bloomberg reports. Such a plan would create headwinds for the dollar.

Dollar-denominated commodities such as oil become more affordable and consequently more desirable to foreign buyers when the greenback weakens.

Separately, TheStreet Ratings team rates the stock as a "sell" with a ratings score of D.

Oasis Petroleum's weaknesses include its feeble growth in its earnings per share, deteriorating net income, generally high debt management risk, disappointing return on equity and weak operating cash flow.
