Geothermal Assessment
FrOG Tech's 30+ cumulated years experience in structural geology, hydrogeology and thermal modelling has led to the development of series of cost effective comprehensive workflows that provides sustainable energy investors and explorers independent advice on the suitability of an area for geothermal prospectivity.
Our expertise has been forged and recognized through work on several national and basin scale projects including Hot Sedimentary and Hot Dry Rock (EGS) geothermal resources assessment for the private and institutional sectors.
