Brent crude was down 12 cents, or 0.2%, at $67.88 a barrel by 0119 GMT after dropping by 0.6% on Wednesday. U.S. oil was also down 12 cents, or 0.2%, at $64.48 a barrel, having fallen 0.3% the previous session.
Government data on Wednesday showed U.S. crude inventories have risen for four straight weeks after refineries in the south were forced to shut due to severe cold weather. An industry report estimating a 1 million barrel-drop had raised hopes the run of gains might have stopped.

“We suspect that stocks will fall soon as refinery activity rises further and crude production holds steady,” Capital said, noting that refineries are “rapidly coming back online.”
U.S. crude inventories increased by 2.4 million barrels last week, an industry report on Tuesday estimated a 1 million barrel-decline. Analysts had on average expected an increase of 3 million barrels.
