Here is FoxNew's pdf file for the 248 oil for food companies. The 248 companies and their countries of origin are listed in the first table here:

The independent Inquiry Committee's report lists Chevron, Mobil, Texaco and Phoenix International as the participating U.S companies in the oil for food program.
Russia, France, Switzerland, United Kingdom, Turkey, Italy, Red China, Liechtenstein, Spain, and Malaysia round out the top ten buyer nations as far as total sales.
Other than that, the list is a who's who of nations.
The pdf file I posted from FoxNews offers the Committee's report findings in tables sorted in a few different ways.
