Resource assessment for deep sedimentary and basement reservoirs

Advanced methods, technologies and conceptual models, for different geological settings, to identify suitable conditions for geothermal resource exploitation, tackling the issue of data scarcity and leveraging the information available. The proposals are expected to contribute to the assessment of environmental and social impacts and to unlock geothermal resources marked by low natural permeability at depths between 2000-6000m.

The scope covers advances beyond the state of the art in equipment, methods and models capable of providing in-depth understanding and predictive power for properties and processes beyond conventional depths. The proposals are expected to take into account the impact of reservoir conditions and parameters (i.e. in-situ stress, temperature, geo-mechanical, chemical properties) on the development and performance of the geothermal resources, covering, when relevant, aspects such as the suitability for different stimulation techniques, well designs and completion technologies, the possibilities for the coproduction of raw materials, wellbore stability.

The proposals are expected to validate the benefit of the proposed solution in the context of state-of-the-art decision and risk analysis methods.

To ensure trust building and communities’ support, partners are expected to practice inclusive societal engagement, which is early, continuous, and sensitive to the technical specificities (e.g. impact on biodiversity, water balance, pollution, land occupation, visual impact, noise as well as geo-mechanical changes (e.g. seismicity) and underground changes (e.g. disturbance of non-targeted aquifers)) that could affect local communities and ecosystems [[ For an example of a methodology for the assessment of sustainability, circularity and contribution to the EU resilience and technological autonomy of clean energy technology in the R&I pipeline, please see Study on circular approaches for a sustainable and affordable clean energy transition]].

This topic requires the effective contribution of SSH disciplines and the involvement of SSH experts, institutions as well as the inclusion of relevant SSH expertise, in order to produce meaningful and significant effects enhancing the societal impact of the related research activities.
