Our Activities



Based in Queensland, Australia, the Project involves gas fields from the Bowen and Surat Basins in south-west Queensland and an LNG Plant on Curtis Island.  Santos operates on the traditional lands of the Gangulu, Bidjara, Karingbal, Port Curtis Coral Coast (PCCC), Mandandanji, Gap B (Murribinbi), Kairi and Iman peoples.

Joint venture partners

Santos - 30.0% (operator)
PETRONAS - 27.5%
Total - 27.5%
KOGAS - 15.0%


Sanctioned in January 2011, GLNG includes the development of CSG resources in the Bowen and Surat Basins in south-east Queensland, construction of a 420-kilometre underground gas transmission pipeline to Gladstone, and two LNG trains with a combined nameplate capacity of 7.8 mtpa on Curtis Island.

The project has an estimated gross capital cost of US$18.5 billion from the final investment decision to the end of 2015 when the second train is expected to be ready for start-up, based on foreign exchange rates which are consistent with the assumptions used at FID (A$/US$ 0.87 average over 2011-15).

GLNG has sales and purchase agreements with PETRONAS and KOGAS for 7.2 million tonnes per annum of LNG in aggregate.

Project status

As at the end of September 2014, the GLNG project is approaching 90% complete and on track for first LNG in 2015.


In line with the 2014 drilling plan, twenty-one wells were spudded in the GLNG acreage during the third quarter, which included 18 development wells (12 in Fairview and six in Roma) and three appraisal wells.

Deliverability of the existing wells in Fairview continues to exceed expectations, with total gross field well capacity in excess of 400 TJ/day at the end of August.  At Roma, field dewatering continues in line with expectations and an initial development well is already producing more than 1.5 TJ/day.

Commissioning of the Fairview 5 gas processing hub was substantially completed during the quarter. The commissioning and completions workforce has now transitioned to commissioning of the Fairview 4 gas processing hub while construction of the Roma 2 gas processing hub is now complete. Commissioning of the pipeline compressor station was completed and construction of the 120-kilometre Comet Ridge to Wallumbilla pipeline loop is now over 85% complete.

Gas transmission pipeline

First gas was introduced into the 420-kilometre gas transmission pipeline from the Fairview field in September with gassing-up commencing in early-October.  Surface reinstatement work has been completed along the entire pipeline right of way. The two QGC pipeline interconnections are complete and pre-commissioned.

LNG plant

Construction of the LNG plant on Curtis Island continues to progress well, with commissioning gas expected to be delivered to the plant in the fourth quarter of 2014. Some commissioning works are already underway, with the emergency power generation run for the first time.

All 111 LNG plant modules have been delivered to Curtis Island from the module yard. All 82 Train 1 modules and 27 of the 29 Train 2 modules have been set on their foundations, and piping installation and cable pulling is progressing. The Train 1 utilities area is substantially complete and work continues on the Train 2 utilities.

Construction of the first LNG tank is well progressed with hydrostatic testing complete and insulation and piping installation underway. Hydrostatic testing of the second LNG tank is also complete.  The LNG loading jetty is substantially complete and its subcontractor has demobilised from site.
