Earthquakes in the Southern Highlands and Hela Provinces of Papua New Guinea have taken out LNG production for about two months.
Energy giant Santos, which has a 13.5% interest in PNG LNG, says assessments of damage indicate it may take eight weeks to complete repairs and restore production.
The Hides Gas Conditioning Plant is safely shut but there has been some damage to equipment that is yet to be fully inspected and repaired. Initial visual inspections show the damage is not significant.
The pipeline has not been damaged and production wells are safely shut.
Santos is donating $US200,000 to aid agencies to provide assistance to isolated communities urgently needing food, water and medical supplies.
A magnitude 7.5 earthquake hit the south west of Porgera, in Papua New Guinea on February 25, killing at least 35 people, damaging roads and causing major landslides.
A State of Emergency had been declared for the earthquake disaster areas in Hela, Southern Highlands, Western and Enga Provinces.
