Fonts-Bouillants (France): towards the first helium production in Western Europe

After having carried out bibliographic researches followed by very encouraging field geochemistry surveys, 45-8 Energy applied in 2019 for the “Fonts-Bouillants” exploration license in order to evaluate the potential for joint exploitation of helium and carbon dioxide which are naturally seeping along the Saint-Parize fault (SPF). 45-8 ENERGY has thus conducted a diversified geophysical acquisition program to benefit from different methods. The high-resolution gravity data has particularly well characterized the structural scheme. A total of 10 shallow boreholes have been realized (100m deep) in order to calibrate the stratigraphy in areas with high uncertainty but also to test the possible presence of gas in structures prone for gas accumulation. 2 wells were particularly successful and were completed after exhibiting strong gas influx while drilling. The implementation of a pilot production facility is underway. Such unit will separate and purify helium in one side and food grade CO2 in the other side. Indeed, pure CO2 is actually a sought-after resource used in beverage or freezing industries; capturing it prior reaching the atmosphere will therefore enable a valuation instead of an inevitable natural geological rejection through the SPF.
