Nigeria dropped slightly from its traditional third largest exporter of crude oil to the United States to number four in October 2010 exporting 812 barrels per day, down from 1107 in the previous month.
The figure made public recently shows that Canada continues to lead crude oil exports to its neighbor selling 1840 barrels per day, although it recorded a slight drop from 1936 barrels previously.
Analysis of the monthly data on the origins of crude oil imports in October 2010   shows that three countries exported more than 1,000 thousand barrels per day to the United States.
The data made available by the U.S Energy Information Administration indicated that  top five exporting countries accounted for 69 percent of United States crude oil imports in October while the top ten sources accounted for approximately 85 percent of all U.S. crude oil imports.
The top five sources of US crude oil imports for October were Canada (1,840 thousand barrels per day), Mexico (1,178 thousand barrels per day), Saudi Arabia (1,114 thousand barrels per day), Venezuela (887 thousand barrels per day), and Nigeria (812 thousand barrels per day).
The rest of the top ten sources, in order, were Colombia (400 thousand barrels per day), Angola (311 thousand barrels per day), Algeria (259 thousand barrels per day), Kuwait (215 thousand barrels per day), and Ecuador (203 thousand barrels per day). Total crude oil imports averaged 8,489 thousand barrels per day in October, which is a decrease of 678 thousand barrels per day from September 2010. Canada remained the largest exporter of total petroleum in October, exporting 2,345 thousand barrels per day to the United States, which is a decrease from last month (2,475 thousand barrels per day). The second largest exporter of total petroleum was Mexico with 1,345 thousand barrels per day.
