GEORGETOWN, Aug 8 (Reuters) - An Exxon Mobil-led

consortium began production at a fourth floating production,

storage and offloading vessel at the Stabroek Block in Guyana on

Friday, bringing total capacity from the oilfield to over

900,000 barrels of oil per day, Exxon said.

The floating vessel named One Guyana brings the joint venture a

step closer to its target of 1.7 million barrels of oil

equivalent per day by 2030 from the prolific block, one of the

biggest oil discoveries in years that has driven soaring profits

for the joint venture.

Chevron ( CVX ) closed its acquisition of Hess, which held a 30% stake

in the consortium, in July after prevailing in a lengthy legal

battle with Exxon that centered on access to the block, where

more than 11 billion barrels of recoverable oil and gas have

been found since 2015.

The U.S. oil producer is now a partner alongside Exxon and

China's CNOOC, which holds 25%.

The vessel allows the consortium, which controls all oil output

in Guyana, to develop the Yellowtail and Redtail fields. Oil

produced from One Guyana will be marketed as Golden Arrowhead

crude, Exxon said.

The start-up of One Guyana is four months ahead of schedule,

Exxon added.
