NEW YORK (TheStreet) -- Shares of Southwestern Energy (SWN - Get Report) were gaining 5.13% to $15.16 in late morning trade on Thursday as oil prices advanced.

Crude oil (WTI) was up 3.78% to $47.22 per barrel while Brent crude was climbing 3.61% to $49.71 per barrel this morning.

Oil prices were higher today as concerns over a global oversupply eased. The American Petroleum Institute reported late yesterday that U.S. crude stocks dropped by about 12.1 million barrels last week.

Analysts had been looking for a growth of 200,000 barrels for the period, Reuters reports.

The U.S. Department of Energy will post its own data on U.S. crude inventories later today.

If it corroborates the report from yesterday, it will be the biggest drop in inventories since 1985, according to Reuters.

Additionally, Tropical Storm Hermine negatively impacted crude production in the impacted region this past week, Reuters reports.

Southwestern Energy is a Spring, TX-based independent oil and energy company.
