GEORGETOWN/LONDON, June 10 (Reuters) - The first crude

cargo from Guyana's fourth oil production platform, which

arrived in the country in April and is being installed, is

scheduled to be exported between late August and early

September, the government told Reuters on Tuesday.

A consortium by U.S. companies Exxon Mobil ( XOM ) and Hess

and China's CNOOC controls all crude and gas

output in Guyana. Each party individually exports its share of

production, and the government also is entitled to a share as

profit oil.
