Isotherm Testing

GeoGAS has been providing gas sorption isotherm (both CH4, CO2 and N2) analysis for various coal mining and coal seams gas exploration companies since 1999. GeoGAS has performed in excess of three thousand isotherm analyses for over forty customers in Australia, New Zealand, China, Africa, Indonesia and Europe and has the capacity to analyse multiple samples at a single time at reservoir temperatures ranging from ambient to 90°C.

Adsorption isotherm testing is conducted on either an “as received” moisture basis (moisture remaining in the sample once it is removed from the gas canister, wrapped, and stored in the freezer) or an “equilibrium” moisture basis as selected by customers.

Please note that reservoir temperature logging data is required for specification of isotherm tests.
