WHAT IS COAL SEAM GAS?
Coal seam gas (CSG) is natural gas in coal deposits, trapped by water and ground pressure. Here’s how it’s extracted.
DEVIATED DRILLING
Arrow’s deviated drilling/multi-well pad concept reduces impacts on farmland.
LOW POINT DRAINS AND HIGH POINT VENTS
What are they and how do they work?
THE WATER NETWORK
Coal seams yield water as well as gas. We have an extensive water network to maximise the benefits of this precious resource.
LOW PRESSURE HEADER
Arrow's low pressure header is a 125km pipeline that connects our gas fields with compression infrastructure. It also includes water pipelines and telecommunication networks. This animation illustrates how it is all connected.
CENTRAL GAS PROCESSING FACILITY
Gas compression facilities clean the natural gas and then compress it for transport.
BRAEMAR 2 POWER STATION
Here’s how southern Queensland’s Braemar 2 power station turns natural gas into electricity for the Australian domestic market.
GROUNDWATER IN THE SURAT BASIN
It’s important for agriculture, home and business; here’s how we’re safeguarding the Condamine Alluvium in the Surat Basin.
SEISMIC SURVEYS
Seismic surveys help us to map rock formations below the earth's surface. We use this information to target coal seams for gas extraction. This animation shows how the process works.
