Oil prices were up as much as 2 percent on Wednesday, reacting to the possibility of another surprise weekly drop in U.S. inventories amid an industry strike in Norway that threatened to cut North Sea crude output.

The American Petroleum Institute, a trade group, reported a 7.5 million barrel drop in U.S. crude inventories for the week ended Sept. 16, versus a 3.4 million-barrel drop forecast by oil market analysts polled by Reuters. [API/S]

In Norway, more than 300 oil service workers went on strike as wage talks broke down, hitting operations of five large subcontractors to the domestic oil and gas industry.

Also supporting crude prices was speculation that OPEC and oil producers will agree to some sort of a production-freeze deal in talks in Algeria next week, and that the Federal Reserve will not hike U.S. interest rates in a policy decision due at 2:00 p.m. EDT (1800 GMT).

Brent crude futures LCOc1 were up 70 cents, or 1.6 percent, at $46.58 per barrel by 9:43 a.m. EDT (1343 GMT).

U.S. West Texas Intermediate (WTI) crude futures CLc1 rose 95 cents, or 2.1 percent, to $45.
