GEORGETOWN, March 11 (Reuters) - The eighth energy

project in Guyana of a consortium led by U.S. major Exxon Mobil ( XOM )

will produce up to 1.5 billion cubic feet per day (bcfd)

of natural gas and 290,000 barrels per day on condensate through

a floating production facility that will have capacity to export

the fuel, the group told the government.

The Longatil project's details, which include the

development of the Longtail, Tripletail and Turbot discoveries

off Guyana's coast, were included in the group's request for

environmental authorization, published by Guyana's government

and seen by Reuters on Tuesday.
