April 13 (Reuters) - A leak in a pipeline that carries oil
from U.S. Gulf of Mexico offshore facilities has halted
production at two fields, Exxon Mobil Corp and Royal
Dutch Shell said on Monday.
Shell said it temporarily halted production on its
100,000-barrel-per-day deepwater Perdido production hub last
Thursday after a subsurface leak was discovered on Exxon's
Hoover Offshore Oil Pipeline System (HOOPS). Production on
Exxon's Hoover platform also was halted because of the leak,
Exxon said.
The HOOPS pipeline has been closed for repairs, a
spokeswoman for Shell said.
Exxon has notified government agencies and shippers and has
responded to an onshore release of crude oil at a facility in
Freeport, Texas, spokesman Todd Spitler said on Monday.
"We anticipate resuming flow on the line in a timely manner
once it is safe to do so," he said. Exxon did not say what
caused the leak or how much production was affected.
HOOPS connects the Exxon-operated Hoover, Marshall and
Madison offshore fields, which combined produce about 4,000
barrels of oil per day, according to a 2018 marketing brochure.
Shell's Perdido hub is moored in some 8,000 feet (2,438 m)
of water about 200 miles (322 km) south of Galveston, Texas, and
is a joint venture among Shell, BP Plc and Chevron Corp
.
The 153-mile (246-km) HOOPS pipeline brings oil from several
offshore oilfields to the Quintana Terminal near Freeport,
according to an Exxon website.
