Crude oil inventories increased 9.57 million barrels last week, the American Petroleum Institute said.
The Energy Department is scheduled to release its inventory report at 11 a.m. tomorrow in Washington, a day later than usual because of the Christmas holiday.
The government report may show stockpiles of crude oil fell 2.5 million barrels last week, according to the median of 10 responses in a Bloomberg News survey. Gasoline inventories probably dropped 500,000 barrels, the survey showed. Distillates were expected to decrease 650,000.
API collects stockpile information on a voluntary basis from operators of refineries, bulk terminals and pipelines. The government requires that reports be filed with the Energy Department for its weekly survey.
