Two Petsec Offshore Gas Fields Shut-In Ahead of Isaac's Landfall

Australia-listed Petsec Energy said Tuesday in a statement that its Main Pass 19/18 and Chandeleur 31/32 offshore gas fields have been shut-in and the offshore personnel related to these fields have been evacuated ahead of the approaching Tropical Storm Isaac.

The company added that the Marathon and Main Pass 270 offshore gas and condensate fields could be shut-in as well prior to Isaac's arrival. 

"We are anticipating that these fields could be shut in, but we have not done so or evacuated personnel as the hurricane could take a different route," a company spokesperson representing Petsec told Rigzone through a telephone interview. 

"These are safety measures that Petsec take every year during the hurricane season, so our shut in operations are extremely swift and efficient," the spokesperson added. 

The Main Pass 19 lease operated by Petsec lies in 26 feet of water. It has a four pile platform with compression facilities and a 3,000 barrel oil storage facility. The Main Pass 18 lease lies directly north of Main Pass 19, and production from this field flows through the Main Pass 19 facility. 

Chandeleur 31/32 are leases lie in 66 feet of water. There are two wells on Chandleur 31 which were drilled from and produce through a tripod supported facility. On Chandleur 32, one well is producing from a dual completion. Production from Chandleur 32 is tied back to the primary production facility on Chandleur 31.

Isaac is expected to strengthen and make landfall as a hurricane Wednesday on the anniversary of Hurricane Katrina's descent in New Orleans on August 29, 2005. Katrina was the deadliest and most destructive of the 2005 Atlantic hurricane season and one of the five deadliest hurricanes in U.S. history, according to the National Hurricane Center (NHC).

The Bureau of Safety and Environmental Enforcement (BSEE) reported Monday that 78.02 percent, or 1.076 million barrels of oil per day (bopd) have been shut in, while 48.13 percent, or approximately 2.1 billion cubic feet per day of natural gas production has been shut in.
