A ban on offshore drilling in the Gulf of Mexico could cost the US offshore services industry almost $11bn a year, according to a new report.

The ban currently in place following the Gulf of Mexico oil disaster could represent a loss of business opportunities for equipment manufacturers and suppliers, according to research group Datamonitor.

Oil production in deepwater areas in the Gulf of Mexico amounts to nearly 1.8 million barrels per day.

New fields expected to be in operation by 2014 in the Gulf are estimated to add a further 250,000 barrels per day, about 14% of its current production.
