Once we find gas, we plan the safest way to extract it so we can then develop and deliver it to our customers. 

Our exploration and production portfolio includes the Bowen and Surat basins in Central Australia, as well as interests in the Browse Basin in Western Australia and the Beetaloo Basin in the Northern Territory.

How natural gas is extracted


Once we’ve secured approvals from land owners, government and other stakeholders, we explore below the land and ocean beds for natural gas.


If we find gas, our engineers and analysts work out how to extract it. 


If feasible, we begin drilling wells to extract the gas. 

Gas processing

We process the extracted gas to remove unnecessary elements like water.

Gas pipelines

A network of pipelines distribute gas daily to residential and business customers.

Gas-powered stations

Some of the gas is sent to our gas-powered stations to make electricity.

Gas production begins

Once we explore areas and find that natural gas is viable to produce, we focus on production of that source to supply to our customers.

We operate coal seam gas (CSG) production plants as part of Australia Pacific LNG in Queensland. This supplies close to 30% of domestic east coast gas demand.

Surat and Bowen basins in Queensland

Origin is the upstream operator for Australia Pacific LNG and is responsible for the development of its CSG fields in the Surat and Bowen basins and the main transmission pipeline that transports the gas to the LNG facility on Curtis Island near Gladstone.

We also have a number of CSG interests in southwest and central Queensland including the Galilee Basin and Denison Trough in the Bowen Basin.

Australia Pacific LNG

The $24.7 billion Australia Pacific LNG project commenced production in late 2015, with the first cargo of liquefied natural gas (LNG) shipped on Saturday, 9 January 2016.

The project converts coal seam gas (CSG) to LNG for export to Asia - delivering a cleaner, greener sustainable energy source.  

The project has a life span of at least 30 years and is a joint venture between Origin (37.5%), ConocoPhillips (37.5%) and Sinopec (25%).

Ironbark project

Ironbark is a wholly Origin-owned project. It's located in the Surat Basin, and is in the exploration and appraisal stage. This means that the economic and business potential of the proposed development is being evaluated.

As part of this stage, Origin operates a small number of pilot, appraisal and monitoring wells.

The project aims to produce gas into a growing market in Australia, and if constructed it will bring employment, skills development and business opportunities to the Tara region.

Other basins

We have offshore exploration interests in the Browse Basin in Western Australia and onshore exploration interests in the Beetaloo Basin in the Northern Territory. 

Origin Energy operates three exploration permits in the Beetaloo Basin. Together with project partner Falcon Oil & Gas, we are evaluating the potential of Proterozoic rocks of the Velkerri and Kyalla formations.

Exploration is on hold due to a moratorium in the Northern Territory.
