| Abstract |
The GeoHeatTM deep closed-loop technology is designed for producing reliable geothermal energy anywhere. With the shortest time for the first Mega Watt, the minimum environmental impact, no corrosion, no scaling, and no seismicity risks, it is the most reliable and sustainable option in the market for large-scale, long-term energy production. The GeoHeatTM harvesting technology incorporates a multidisciplinary workflow for assessing its feasibility under the various scenarios of geological, thermal, and mechanical information. This entails uncertainty quantification and an engineered strategy to maximize energy production and the rates of returns on investments. This integrated approach includes visualization and mapping as keys for effective communication between the internal and external stakeholders involved in the projects, warranting not only informed but also unbiased decision-making along the strategy for all the geological and development scenarios: Greenfields, blind systems, unexplored volcanic, metamorphic, plutonic, sedimentary basins, and their basement rocks, along with hydrothermally developed systems. A generalized workflow for geologically delimiting the targets and estimating their GeoHeatTM feasibility through mapping is presented here. Each developmental stage and resource type will use an adaptation of this workflow for confirmation of the geothermal resource in place and the sustainability of the heat harvesting in time. The GeoHeatTM feasibility index then provides the developer with an integrated and fit-for-purpose indicator from the techno-economical perspective. This index accounts for the different resource de-risking methods, from integrating massive amounts of information to adding new datasets, through slim-hole drilling and geophysical surveying. Two case studies of the workflow application, within two different data maturity scenarios, serve as an illustration for common intraplate settings where conventional geothermal systems are not easy to find, making GeoHeatTM the best alternative for renewable energy production. The workflow helps both during preliminary screening and decision-making process but also a quantitative feasibility index estimation for focused exploration (e.g., Slim-hole drilling, extra geophysical surveying) and development program inputs. |
