Oil futures built on Wednesday's 2% gains in Asian trading Thursday ahead of weekly U.S. inventory data.
--February light, sweet crude on the New York Mercantile Exchange was recently up 0.5% at $61.92 a barrel in the Globex trading session. March Brent rose 0.2% to $67.97.
--Wednesday's jump to 3-year highs was attributed by some to demand worries both in Iran--where antigovernment protests are ongoing--and the US--where ongoing cold weather has raised concerns about some petroleum-industry infrastructure.
--Meanwhile, late Wednesday's industry-group reading on U.S. inventories was largely in line with what the government's Thursday release is expected to show.
