Coal seam gas
Coal seam gas (CSG), also called coal bed methane, is mostly methane in composition and is typically attached to the coal along its natural fractures and cleats. This gas is released when pressure on the coal seam is reduced, usually by removal of water from the seam.
CSG is an important energy resource in Queensland and production of this gas now makes up an increasing proportion of Queensland gas demand.
The Queensland Government recognises landholders face increasing pressure for access to their land for gas and other resources exploration and development.
New land access laws were introduced into Parliament in mid May, 2010 to improve relationships between landholders and resources companies related to land access for exploration and development purposes.
CSG exploration is carried out under the Petroleum Act 1923 and the Petroleum and Gas (Production and Safety) Act 2004. Coal seam gas production is administered under the Petroleum Act 1923, the Petroleum and Gas (Production and Safety) Act 2004 and the Mineral Resources Act 1989.

CSG water management
Water is a primary by-product of CSG development. The quality of the water ranges from potable to saline and may be rich in other constituents that make it unsuitable for many uses.
