Crude-oil futures extended losses in Asian trade Wednesday on bearish U.S. stockpile data, and as markets await the next wave of sanctions against Russia.

On the New York Mercantile Exchange, light, sweet crude futures for delivery in September traded at $102.09 a barrel at 0620 GMT, down $0.30 in the Globex electronic session. September Brent crude on London's ICE Futures exchange fell $0.09 to $107.24 a barrel.

Late Tuesday, data from the American Petroleum Institute, a trade body, showed a 555,000-barrel decline in U.S. crude stocks, for the week ended July 18. It also said gasoline and distillate stocks fell last week.

The data was bearish overall, with a smaller-than-expected draw from U.S. oil inventories and a larger-than-expected build in the oil products stocks, analyst Tim Evans at Citi Futures said.

The more closely watched inventory report from the U.S. Energy Information Administration is due later Wednesday and analysts expect inventories to have fallen by 2.5 million barrels.

Meanwhile, U.S. intelligence officials have presented their most detailed case yet that Russian-backed Ukrainian separatists shot down a Malaysia Airlines jetliner last week.

Malaysia is studying actions that can be taken according to international law in the downing of Malaysia Airlines Flight 17 in Ukraine, Prime Minister Najib Razak said Wednesday.

Mr. Evans said the Brent crude market "remains relatively subdued and complacent regarding the potential supply ripple effects related to increased sanctions against Russia over events in Ukraine" or the insurgency in Iraq, or the militia battles in Libya.

Nymex reformulated gasoline blendstock for August--the benchmark gasoline contract--fell 107 points to $2.8700 a gallon, while August heating oil traded at $2.8523, 19 points lower.

ICE gasoil for August changed hands at $880.25 a metric ton, down $2.25 from Tuesday's settlement.
