Crude production of U.S. decreased 23,000 to 8.802 million barrels a day the week ended May 6, according to EIA's weekly report released last Wednesday.

Last week US oil rig count fell for the eighth straight week. According to data released last Friday by oil service company Baker Hughes, the number of US oil rigs in use fell by 10 to 318.
