HOUSTON (Reuters) -Oil prices rose on Wednesday, buoyed by government data showing U.S. crude oil and fuel inventories fell last week and by mounting concerns about tighter global supply following the U.S. threat of tariffs on nations buying Venezuelan crude. U.S. crude stocks, gasoline and distillate inventories fell last week, the U.S. Energy Information Administration said on Wednesday. Crude inventories fell by 3.3 million barrels to 433.6 million barrels in the week ended March 21, the EIA said, a deeper draw than the 956,000 barrels that analysts had expected in a Reuters poll.
