HOUSTON, May 8 (Reuters) - An Exxon Mobil led

oil consortium has achieved peak production of 252,000 barrels

per day from its Liza Unity production vessel, Exxon Guyana

Country Manager Alistair Routledge said on Wednesday.

The consortium, which includes Exxon, Hess and CNOOC

, expects to inaugurate output next year using its

newest vessel, called One Guyana, Routledge said in remarks at

the Offshore Technology Conference in Houston.

New wells in the deepwater Stabroek block, home to the

largest oil discovery in nearly a decade, are being completed in

an average of 35 days, a record low for deepwater projects, he

said.

"Guyana will become the second largest oil producer in Latin

America after Brazil, soon," Routledge said. "This is a

tremendous operation... with the sixth project, we will have 500

kilometers (311 miles) of flowlines in total."

Exxon as operator plans this year to drill two "exciting but

high risk" opportunities, called Redmouth and Trumpetfish, that

target oil reserves, he said. The wells will test the reservoir.

For their fifth offshore project, called Uaru, the group has

hired Mitsui Ocean Development & Engineering Co. (Modec) to

build the Floating Production Storage and Offloading (FPSO)

vessel.

A sixth project, called Whiptail, was recently sanctioned,

and is expecting to begin output by the end of 2027. It would

bring the group's total output capacity in the country to 1.3

million barrels per day.
