Gas measurements
In recent years Solexperts specialised in in-situ gas measurements both in the gas phase and dissolved in groundwater. In France, a very successful cooperation was established with the Institut Georessources of the University of Lorraine and in Switzerland with the ETH and EAWAG. Several systems have been successfully used in various rock laboratory experiments and CBM drilling. For the developed gas measurement technology, Solexperts filed a patent in November 2022 (EP 22210240, Probe and method for gas analysis in boreholes) and registered two trademarks; SurfMoG® for near-surface applications and SysMoG® for measurements in (deep) boreholes. SysMoG-GH2ASBUSTERS, a unique sampling system for dissolved gases in boreholes up to 1500 m, was developed for the exploration of natural hydrogen deposits.
Current applications
- Exploration of natural hydrogen in Lorraine
- Exploration of CBM sites (Coal Bed Methane) in Lorraine
- Observation of steel corrosion and microbiological processes in repository demonstration experiments in the rock laboratories
- Experiments to prove the efficiency of geological barriers in the context of CO2 sequestration
