PERTH, March 29 (Reuters) - Woodside Petroleum Ltd (WPL.AX), Australia's second-largest oil and gas producer, said on Saturday it has resumed production at its 30,000 barrel per day Enfield oil field off Western Australia after a cyclone threat passed.

Woodside spokesman Roger Martin said Enfield, which was shut down on Thursday evening, has resumed production on Friday 9 p.m. local time.

He said operations at other projects, such as the Cossack Pioneer and the North West Shelf liquefied natural gas (LNG) project, have not been affected.

Cyclone Pancho, which was a category-three storm at its peak, is located 425 kilometres west of Carnarvon and is currently moving south southeast at around 13 kilometres per hour at 3 a.m. local time, Australia's Bureau of Meteorology said on its Web site.

"Pancho has weakened dramatically over the past 12 hours and is expected to weaken to a tropical low during today," the bureau said.

It added that Pancho was not expected to produce damaging or destructive winds in communities along the west coast.

BHP Billiton Ltd/Plc (BHP.AX)(BLT.L), which operates the 80,000 bpd Stybarrow oil field off Western Australia, had said on Friday it has not suspended operations there.

Chevron (CVX.N), which also has oil fields in the area, said on Friday production was not affected.

Tropical cyclones typically batter the region between November and April, forcing offshore oil drillers as well as miners, such as Rio Tinto (RIO.L)(RIO.AX) and BHP to suspend operations and evacuate staff.

Last month, a powerful cyclone forced oil companies, including Apache Corp, Woodside and BHP to shut over 220,000 barrels a day of oil production, about 40 percent of Australia's output, for nearly a week.
