Overview of the project
Application and use of helium gas geochemistry in the ground atmosphere for geothermal exploration.
The main objective of this project is to carry out a technical feasibility study on the application and use of surface gas geochemistry on the islands of Tenerife and Gran Canaria as a novel geochemical technique for geothermal exploration. Geochemical and geophysical studies are key to selecting suitable areas for exploratory drilling.
The aim of this project is to use novel, simple to apply and low-cost methodologies to carry out work prior to geothermal exploration in those areas susceptible to geothermal exploitation that present thermal and gas anomalies both at surface and at depth.
The proposed methodologies are based on geochemical gas (helium) prospecting studies in the surface environment of the selected areas, the northwest sector of Tenerife and the southeast sector of Gran Canaria. Helium gas, due to its physical properties (light, inert) is an ideal gas for investigating and delimiting the existence of areas of greater permeability and ascent of fluids of deep origin to the surface, one of the aspects of greatest interest for geothermal exploitation. The results of this project will allow progress to be made in the study of the feasibility of geothermal exploitation in the chosen study areas, as well as progress in research that could lead to the development of geochemical techniques that are decisive for geothermal exploration in other areas of the world.
