Crude-oil futures extended gains in Asian trade Friday, helped by a decline in U.S. oil inventories and a softer U.S. dollar.

On the New York Mercantile Exchange, light, sweet crude futures for delivery in July traded at $58.39 a barrel at 0318 GMT, up $0.71 in the Globex electronic session. July Brent crude on London's ICE Futures exchange rose $0.58 to $63.16 a barrel.

U.S. commercial crude-oil inventories fell by a stronger-than-expected 2.8 million barrels in the week ended May 22, the U.S. Energy Information Administration said Thursday.

However, U.S. crude production jumped to 9.57 million barrels a day, breaking out of the production plateau it has been coasting on since March, partly due to new oil fields ramping up in the Gulf of Mexico, Societe Generale said in a report.

"With OPEC's June 5 meeting right around the corner and no chance of a policy change, we will continue to focus on U.S. production and production costs," the bank said.

Nymex crude is down by around 3.2% this month, and Brent crude is down by around 6.2%, taking the gas out of the oil-price rally over recent weeks. Investors are keeping to the sidelines ahead of next week's meeting of the Organization of the Petroleum Exporting Countries.

Most market participants are factoring in no change to OPEC's production ceiling of 30 million barrels of oil a day and its recent stance of not adjusting output levels to support prices.

"With [oil] prices forecasted to average higher in coming years and OPEC production costs amongst the lowest in the industry, we expect OPEC will allow prices to 'correct' the market while safeguarding as much of their export revenues as possible," analysts at BMI Research, a unit of Fitch, said.

They also said that domestic oil consumption is rising in many OPEC countries due to massive new refineries and oil-burning electricity plants. Due to this, OPEC's oil production growth will be a function of domestic demand rather than export strategy, BMI's analysts said.

The research firm is bullish on Chinese oil demand and said strategic stock-building and rising consumption from small-capacity teapot refiners will buoy China's crude imports in the second half of this year and in 2016.

Meanwhile, investors are tracking debt negotiations in Greece, preliminary U.S. first-quarter gross domestic product data and U.S. drilling rig-count numbers due later Friday for more cues.

Nymex reformulated gasoline blendstock for June--the benchmark gasoline contract--rose 164 points to $2.0015 a gallon, while June diesel traded at $1.8856, 152 points higher.

ICE gasoil for June changed hands at $577.75 a metric ton, up $7.00 from Thursday's settlement.
