Depending on the primary element, unique approaches are offered from a service standpoint. For example; if they key element is Hydrogen, Rudiger Re-chem uses a passive system. The passive system can eliminate Hydrogen artefacts created from drilling operations
It is important to know that rotary drill probes do create hydrogen artefacts in the analytical data, because of the heat generated between the metals and the rocks. These increased temperature environments will create chemical interactions where the Hydrogen is dissociated from the parent compound and is found in the soil gas sample. Rudiger Re-chem uses a unique passive system. The probe is introduced into the sub soil for 12 to 24 hours prior to any extraction of Hydrogen. This timeline eliminates the Hydrogen artefacts because the ample amount of time allows the Hydrogen to dissipate and therefore only leaving the ambient sub-soil Hydrogen concentration that was found in the region prior to drilling. The passive approach also reduces the Hydrogen “Breathing” as mentioned in Part 3 of the articles. Part 3
Notes to be mindful of when exploring for Hydrogen:
- Very volatile and needs special handling to mitigate escaping gas
- Very reactive; therefore all sampling methods must be aware of this
- Hydrogen has “Breathing” effects throughout the day
- Artefacts in the analytical data may be present if not mitigated during sampling
Rudiger Re-chem also has a unique probe designed for this use to avoid any Hydrogen creation from the oxidation of Iron compounds found in most tools. The oxidation of the Iron generates Hydrogen when in contact with water or moisture, which will cause fails positives in the analytical dataset.
Geochemical samples are analyzed for both hydrocarbons and helium in exploration for helium in the Phanerozoic, a plot of helium vs methane and hydrogen is very useful in your evaluation of whether helium is associated with condensate, rich/dry gas or nitrogen. For the project depicted here, helium is associated mainly with nitrogen. If any of the helium anomalies do not match with condensate or rich/dry gas anomalies, the associated gas in the reservoirs the helium anomalies represent is likely to be nitrogen. Usually helium is more concentrated in nitrogen reservoirs but such reservoirs are likely to be close to the basement requiring deeper drilling. Associated hydrocarbons need to be disposed of if they are not marketable.
