Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.Natural gas is fundamental to our way of life – we use it for cooking, heating, electricity and power.
Over 90% of the natural gas used in Queensland comes from coal seams, but how is it formed and how is it produced? Take a look at how we go about developing our coal seam gas resources safely and sustainably, as we build a new industry that will power the Queensland economy for many years to come.

Natural gas can be found beneath the ocean or the lands, close to the Earth’s surface or deep below the crust. Natural gas is most commonly extracted by drilling vertically from the Earth’s surface.After drilling the well, a concrete and metal casing is installed into the hole, and a collection pump is built above this.
A gathering system may need one or more field compressors to move the gas to the pipeline or the processing plant. A compressor is a machine driven by an internal combustion engine or turbine that creates pressure to “push” the gas through the lines.
