Tap Oil says the Harriet joint venture has re-started gas sales to the domestic market following the Varanus Island gas explosion.
The company said the largest gas train within the project has been reinstated and is now processing gas from the Wonnich field at a rate of some 70 terajoules per day, representing 65 per cent of daily gas production.
Liquids production is now at over 4000 barrels a day and resale arrangements for Tap's third party gas from the John Brookes field is at around 80 per cent of volumes prior to the pipeline incident.
The repair project at Varanus Island remains within budget, with further gas and oil production to be phased in over the next few months, Tap said.
In June, a third of the state's gas supply was cut when an explosion occurred at Varanus Island, throwing various sectors into disarray.
Additionally, the company also received its second interim payment from insurers, bringing the total payments for business interruption for the period to the end of September to $9.3 million.
The interim payments are subject to finalisation of the overall claim and represent a partial payment only for business interruption claims for the period.
