About GeoGAS

GeoGAS provides Laboratory and Consulting services to the mining and CSG industries.

GeoGAS has over 30 years’ experience in consulting and laboratory testing and one of the most comprehensive gas reservoir databases in Australia. Our experience and capabilities cover underground mine gas management through to coal bed methane gas production.

Our testing and consulting services help our customers to manage gas released during the mining process, define the nature and value of their coal and gas resources, prepare CSG statements for lease applications and comply with environmental legislation on carbon and greenhouse gas emissions.


At GeoGAS, we are committed to putting Health and Safety first.

Our Safety Goal is that our people, contractors, customers and members of the public are not injured due to our activities or actions.

GeoGAS has a formal ‘Health and Safety Policy’ and ‘Health and Safety Plan’ by which all employees must abide.


GeoGAS was established in 1990 in Wollongong by Dr Ray Williams, a coal and engineering geologist.  Since then it has grown its consulting and laboratory testing capabilities to provide a comprehensive service in support of mine gas management and gas production.

GeoGAS’ fast desorption gas content method was developed in 1993 to provide faster turnaround times needed in gas content compliance testing for outburst management. The method is extensively used in mine exploration and is arguably the most widely used gas content method in the Australian coal industry. Allied to the fast desorption gas content method is the Desorption Rate Index (DRI) which is used to define outburst threshold limits.

GeoGAS opened its second laboratory in Mackay in 1996 to service mines in the Bowen Basin of central Queensland.

By the late 1990’s GeoGAS had a broad range of consulting services built around laboratory testing, mine gas management, gas reservoir assessment and gas emission/production modelling. The concept of gas domain modelling was introduced in 1999 and has since been used to rationalise exploration programs, decrease risk and provide input to uncertainty modelling.

GeoGAS entered the coal bed methane (CBM) industry in 2000 by providing laboratory and gas production assessments for the Moranbah Gas Project. This was the first successful commercial CBM project in Australia.

GeoGAS attained NATA accreditation in gas chromatography testing at both its Mackay and Wollongong laboratories in May 2013.
