Oil futures were up slightly in early Asian trade on Thursday after losses the previous session on official figures showing a sixth consecutive week of inventory gains in U.S. crude stockpiles. Crude prices slumped as much as 4 percent on Thursday after the Energy Information Administration said U.S. crude inventories added 2.85 million barrels last week, in line with forecasts, despite a drop in imports to the lowest level since 1991 (EIA/S). U.S. crude was up 5 cents at $46.38 a barrel by 0621 GMT.
