(Updates with offshore evacuation, production losses)
By Erwin Seba
HOUSTON, Sept 15 (Reuters) - More than a quarter of U.S.
offshore oil and gas production was shut and key exporting ports
were closed on Tuesday as Hurricane Sally churned off the U.S.
Gulf Coast, flooding coastal cities and pelting states with
heavy rains.
Sally continued to weaken Tuesday afternoon to a Category 1
hurricane on Tuesday and largely stalled offshore with sustained
winds of 80 miles per hour (128 kph). It is expected to bring
life-threatening flooding through Wednesday from Mississippi to
Florida, the U.S. National Hurricane Center said.
The storm's trajectory takes it through the prime U.S.
offshore production areas on a path toward western Alabama,
sparing some larger Gulf Coast refineries from high winds.
Royal Dutch Shell said it shut its Appomattox oil
platform about 80 miles off the coast of Louisiana, joining BP
, Chevron Corp and Equinor in closing
facilities less than one month after Hurricane Laura forced up
to 1.5 million barrels per day of output to close temporarily.
Nearly 500,000 bpd of offshore crude oil production and 28%,
or 759 million cubic feet per day (mmcfd), of natural gas output
were shut in the U.S. Gulf of Mexico, according to the U.S.
Interior Department.
U.S. crude oil futures rose nearly 3% and gasoline
futures climbed 2.2% on Tuesday on the hurricane-related
oil production and refinery shut-ins despite demand losses from
the COVID-19 pandemic.
The nation's sole offshore terminal, the Louisiana Offshore
Oil Port (LOOP), stopped loading tankers on Sunday, while ports
from the lower Mississippi River east to Pensacola, Florida,
were closed. That will cut off roughly 307,000 bpd of crude and
411,000 bpd of refined products, according to Kpler data.
As of 1 p.m. CDT (1800 GMT) on Tuesday, Sally was about 105
miles (165 km) south of Mobile, Alabama, and crawling toward the
northwest at 2 mph (3 kph).
Refiners in the region have wound down operations. Phillips
66 shut its Alliance oil refinery, which processes
255,600 bpd at a site along the Mississippi River on the coast
of Louisiana.
Shell cut production to minimum rates on Monday at its
227,400-bpd Norco, Louisiana, refinery.
However, Murphy Oil Corp said it was beginning to
restore production at its eastern-most Gulf of Mexico oil
platforms, and Equinor said it expected to return workers to its
Titan platform on Thursday.
