For some soil substrates such as loose sands or unconsolidated loams, conventional gas sampling may be unproductive from the data reliability viewpoint. Simply put, we have all reasons to believe that our Area of Interest, or AOI, may be productive. However, the gas detector in the field demonstrates ZERO or, in best cases, first PPM readings, thus contradicting our preliminary conclusions.
In order to obtain valuable data regarding “stabilized” hydrogen absorbed on the soil grain surfaces, by default we recommend adding the soil sample de-gassing stage to the exploration plan. Using our proprietary technique, we are able to provide the customer with the clear answer to the most important question: are there really significant concentrations of hydrogen in the top soil, or is it just someone’s wishful thinking?
