Helium and Hydrogen Exploration: What to know (Part 3)
A very cheap and reliable green field exploration toll for Helium, Hydrogen, Uranium and Thorium is geochemical soil gas surveys. Rudiger Rechem utilizes a proprietary probe system and methodology that has been specifically developed for the Uranium exploration Industry. The exact same indicators can be used in Helium, Hydrogen and Thorium exploration as well. The technology combines sub-surface signatures in the soil gas at a meter depth to formulate the potential for a source below. Surveys can be set up specifically to what a client requires as well as the geography and access to specific locations. It should be noted that topography and access dictate whether geochemical surveys are conducted on a grid- or non-grid basis. Helium/Hydrogen anomalies do not necessarily correlate with helium reservoirs directly underneath if micro seeps have migrated laterally to the surface by e.g. faults and bedding planes. Bubble maps depict Helium/Hydrogen concentrations if the sampling points are too far apart. This is useful in establishing trends, not so much in matching concentration data with seismic structures.

Unique approaches are taken whether a survey is focusing on Hydrogen results versus other components, because Hydrogen is a very reactive element. Interpretation and methodology are much more refined. Hydrogen has many sources in the sub-surface, which have the ability to hide anomalous trends in the data. Rudiger Rechem has special probes to handle these concerns with their Hydrogen exploration probe, by avoiding the creation of Hydrogen artefacts caused by the probe itself. Hydrogen also conveys a certain “Breathing” aspect that is determined by diurnal and other effects. These probes are left in the sub-surface for longer period to smooth out these fluctuations.
