Established in January 1990, GeoGAS provides gas laboratory and consulting services to the underground coal and coal seam gas industries.

The fast desorption method of gas content and composition testing was developed by GeoGAS in 1992. This method was developed as a response to the “authority to mine” requirements of the outburst prone Bulli seam mines in southern NSW. Its speed and relevance to outbursting conditions has seen the technique applied throughout Australia and New Zealand, as well as in Canada and China.

Application of the GeoGAS desorption rate index (DRI) is widely applied throughout the Australian underground coal industry for the establishment of gas content thresholds for outburst management.

Our Queensland office and laboratory was established in Mackay in 1994 to service the Bowen Basin coal mining and coal bed methane industries.

GeoGAS purchased the gas reservoir simulator—SIMED II—from CSIRO in 1994, thus providing the capability to model gas emission into roadways, as well as gas and water flow into gas drainage boreholes and surface wells.

In 1999 gas sorption isotherm test equipment was commissioned in the Wollongong laboratory.
