Roxanne caused the state owned Pemex to shut down 90% of its drilling in the Gulf of Mexico during its pass as well as halt all shipments from three oil terminals in the southeastern region of the gulf. As a result, Mexico lost millions of dollars. Oil production dropped from 2.838 million barrels a day in September to 1.976 million barrels a day in October or 30.4%. (A rough guess using a price of the Maya Crude averaging about $13.77/b, 30 days in September, and 862,000 barrels a day of lost output yields $356 million, which in 2011 dollars equals about $530 million.) Oil production didn't completely recover in November, so there were some additional losses, but did completely return in December.
