NEW YORK (TheStreet) -- Shares of Oasis Petroleum (OAS - Get Report) were advancing 5.29% to 9.35% in late morning trading on Wednesday as oil prices increased on a higher-than-expected weekly drop in crude stockpiles.

The Energy Information Administration reported this morning that U.S. crude inventories fell by 6.2 million barrels last week to 504.6 million barrels in total.

The drawdown was higher than analysts' expected 3.4 million-barrel draw, Reuters reports.

Additionally, Wall Street projects that OPEC members and other oil producers will come to an agreement about a production freeze next week during the International Energy Forum in Algeria.

At 2 p.m. EDT today, the Federal Reserve will issue a decision about upcoming fiscal policy. Analysts speculate the central bank will not raise interest rates at this time, Reuters notes.

The speculation has weighed on the U.S. dollar today, positively impacting oil prices as the commodity becomes cheaper and more attractive to foreign investors.

Crude oil (WTI) was up 2.27% to $45.05 per barrel this morning while Brent crude was advancing 1.81% to $46.71 per barrel.

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