Oil prices fell in Asia this morning in thin trading after US markets were closed for the Independence Day public holiday.
US crude fell 17 cents to $94.77 a barrel and Brent North Sea crude also dropped 17 cents to $111.22.
Oil was boosted yesterday by the progress of euro zone talks to save debt-ridden Greece. On Saturday, finance ministers approved the next €12 billion slice of a rescue worth €110 billion provided by the European Union and International Monetary Fund.
Crude traders are awaiting data this week from the United States, including a report by the American Petroleum Institute (API) on crude stocks in the world's biggest oil consumer.
The API report on US crude stockpiles is usually released a day before the Department of Energy's weekly petroleum reserves data.
