Very high-temperature reservoirs are a possible target for future geothermal exploration eitherthrough the direct exploitation of super-critical fluids or as a potential high-temperature reservoir forEnhanced Geothermal Systems. By exploiting subsurface fluids at super-critical conditions, i.e.high temperature (>375 °C) and high pressure (>22 MPa), the energy output per well will increaseby a factor of ~10. This will reduce development costs by decreasing the number of wells needed(IEA Technology Roadmap 2011). In order to contribute to the EU strategic energy and climate targets for 2020 and 2050 by fosteringincreased growth in the geothermal energy market through enhanced awareness of the potential ofgeothermal energy production, a database of potential supercritical resources has been launchedby the IMAGE project. Superhot and supercritical resources are expected in the surrounding of still hot magmaticintrusions in the crust. A large part of the IMAGE activity focused on understanding what are thefavorable conditions at a few km depth for shallow magmatic emplacement, beside improvingexploration and investigation techniques for their detection and the related hot water circulation. Ina typical crust with an average thermal gradient of the order of 30-35 °C/km the critical temperatureof a brine (temperature above 450 °C) is reached at depth greater than 12-15 km. However, inmany sites around the world (e.g. Larderello and Phlegraean Fields in Italy, Nesjavellir in Iceland, The Geysers in California) where exploratory boreholes were drilled in high-temperaturegeothermal system (T > 370 °C), reservoir pressures above supercritical conditions (>22.1 MPa)were encountered. These evidences confirm that geothermal reservoirs in supercritical conditions,both in temperature and pressure, exist in the vicinity of cooling magmatic intrusions. Volcanic rifts,extensional basins and/or subduction zones with related shallow crustal magma emplacements,are the more promising environments in which supercritical conditions may be found in the upperto middle crust levels, The compilation of a European database of the favourable indicators of the presence ofsupercritical geothermal resources has been a main task in the IMAGE project. The objective is todefine areas in Europe where supercritical fluids occur at a drillable depth with a manageablechemistry composition can be found. Where do we find fluids at 4-5 km depth with a temperatureexceeding 400 °C? In various regions in Europe, including Iceland, Italy, Azores, Montserrat,Canary Island. What characterizes these areas? Can we find other areas with similar features atgreater depth? We focus on Iceland, where these resources have been searched and studied inthe last decade. We used the experience of research in Larderello, described in detail in otherIMAGE deliverables (e.g. D5.01), to look for indicators applicable over broad areas, in search ofpotential supercritical resources in continental Europe. Since temperature is the key parametercontrolling the presence of supercritical reservoirs at (relatively) shallow depth, mapping ofsupercritical resources was mainly driven by thermal models derived from crustal and lithosphericconstraints and data interpolation from available deep wells. Other information providing indirectindication of crustal thinning and shallow magmatic emplacement have been searched andanalyzed. In particular, we mapped the following indicators: the depth of 400 °C isotherm; theMOHO depth and crustal thickness; the earthquake density combined with the estimated depth ofthe Brittle-Ductile Transition in Europe. Other interesting indicators, e.g. He3/He4 ratio values fromwhich fluids of crustal origin may be inferred, or Curie Point depth that refers to deep temperatureregime, are available only for local areas, and are too restricted to be of use at regional andEuropean scale. The location of recent (Pleistocene-Holocene) volcanism, also dispersed, wasmapped since it provides useful information, but was not used in the computation of final maps. After defining the indicators, their spatial correlation was established by Geographic InformationSystem (GIS) models, and a database was organized. By prioritizing favourable conditions usingGIS spatial analysis methods, the “favourability” map of geothermal resources at supercriticalcondition was then obtained. It provides a clear overview of the distribution of potential resourcesin Europe, based on analytical data.

This report describes MT-inversion techniques with external constraints, Deliverable D5.6 within the IMAGE project. Report analysing the results of MT-inversion techniques with external contraints, describing optimal MT layout and data modelling for obtaining maximum information from MT surveys, including recommendations for opitmised MT site spacing for different a-priori constraints. The first part of the report, which was performed by ISOR, discusses the origin and nature of the static shifts and some tested methods for static shift correction, i.e. joint 1D inversion of co-located TEM and MT and spatial filtering and statistical assumptions about the shifts. A software is introduced which inverts the two datasets for both the resistivity model and the shift of the MT. Besides determining the static shift, joint inversion is an important quality check of the TEM and MT data sets, i.e. weather they are compatible. In EM surveying, software should be used make a preliminary joint inversion of TEM and MT at base camp as a quality control to make sure the field mission is not terminated until god quality data have been collected. Finally, the claim that 3D inversion of MT can deal with the static shifts, i.e. introduce shallow resistivity structures (not resolved by the data) to account for the shifts is tested. The second part was done by ISOR. On one hand the depth-location of a low-resistivity anomaly, as observed from borehole data, is build into the starting model, giving the program a headstart into gaining information on the resistivity in the survey area and on the other hand information on the ductile-brittle bounday location is used to infer the location of a deep low-resistivity anomaly, which is put into the starting model of the inversion. Several tests have been done on the site spacing in MT for 3D inversion.n This was done for MT data from the Hengill area in SW-Iceland, starting with a measurment and model grid of 1 km by 1 km (see, Árnason et al., 2010). Later a measurement and model grid seize of 500 m by 500 m was tested which improved the resolution significantly for the uppermost 1 to 2 km (Árnason, pers. comm., June 2017). Finally, a measure-ment and model grid seize 250 m by 250 m was tested (Benediktsdóttir, pers. comm., June 2017). It only improved the resolution moderately. In the third part performed by CNR, an integrated approach is proposed that greatly improved the knowledge on the deep structures of the system on the basis of the critical review of deep well data, geological and geophysical data and the analysis of new and previously acquired MT data in the Larderello-Travale field. Resistivity models by 2D deterministic inversion was achieved, focusing on the understanding of the reliability of the a-priori model for the inversion procedure. Three sets of starting models were implemented and tested: A homogeneous (without external constraints), a geological model (from the integrated model) and finally an interpolation of 1D models. The resulting models constrained with detailed and accurate geological information as well as using 1D models showed higher resolution than those unconstrained (i.e. from homogeneous half-space). It is demonstrated how the a-priori information from the analysis of MT data, i.e. by PSO optimization in this case, greatly improved the inversion results even those geologically constrained, which is not a trivial issue for the exploration of geothermal greenfield, due to lack of underground data., FP7

This report deals with the activities and results achieved by the seven Joint Activities established in the course of the Geothermal ERA-NET with a minor effort on human resources and financial support. The activities were planned and coordinated as working groups participated by the project partners, and produced survey reports and/or workshop Minutes., FP7

International audience; Sedimentary basins in Northwest Europe have significant potential for low to medium enthalpy, deep geothermal energy resources. These resources are generally assessed using standard seismic exploration techniques to resolve geological structures. The ElectroMagnetic campaign carried-out in Mol area (Belgium) has shown that despite the presence of high level of industrialization, the resistivity of deep formations (>3km) can be recovered from MT and CSEM methods and hence provide very valuable information for the assessment of geothermal resources. 1. INTRODUCTION Sedimentary basins in Northwest Europe have significant potential for low to medium enthalpy, deep geothermal energy resources. These resources are generally assessed using standard seismic exploration techniques to resolve geological structures. However, the electrical resistivity parameter, which can be directly impacted by the presence of a geothermal reservoir is rarely investigated in such context. Therefore, the development of alternative and complementary exploration techniques such as Electromagnetic (EM) techniques may have an important role in reducing the cost and uncertainty associated with geothermal resource assessment.

This report deals with the organization of transnational activities, after their definition in WP4. In the JA1 Phase, in the form of Working Group preparatory activities, a number of workshops, surveys and reports were organized, and their results were discussed in two Geothermal ERA-NET project meetings: a main one held in Brussels on October 2015, and second one held in Ankara, Turkey, on February 2016. During the JA1 activities and these meetings, the consortium partners defined what activities could pass to the advanced phase of implementation (JA2) having a budget for doing so, or were continuing as JA1 activity providing technical reports. Of the seven themes implemented as JA1 activities, also in consideration of time and budget limits, only two JA1 activities (EGIP for the establishment of a European Geothermal Information Platform and OpERA related to operational issues in geothermal installation) proposed a follow up in the form of co-funded Calls. For EGIP, some countries found a common interest in developing a professional and appealing front-end for the pilot platform whose structure and content has been developed in kind. For OpERA, the proposal that found the interest of various countries regarded the organization of a handbook related to operational issues in geothermal installations, named OpERA-pedia, to be published on the Geothermal ERA-NET webpage and constituting a platform for knowledge exchange. These proposed JA2 activities resulted suitable for Calls for Tenders. Administrative issues, including the difficulties of some country to organize a common Call for Tenders, let the EGIP proposal to be dropped, whereas the OpERA-pedia will be organized as a simultaneous Call for Tender in the participating countries. Indeed, the JA1 activities and the experience gained in the Geothermal ERA-NET project has strengthen the transnational partnership by planning concrete joint activities as testified by the setting up of a new proposal for a geothermal ERA-NET in the form of Co-funded action, to enhance cooperation potential in the field of geothermal., FP7

An organic organization and implementation of the available geothermal data in the southern Italian Regions (Campania, Calabria, Puglia and Sicily) useful to improve the exploratlon and exploitation of geothermal reservoirs, is the alm of the CNR project "Evaluation of Geothermal Potential in Convergence Regions" (VIGOR), financed by the Inter-Regional Operational Programme "Renewable Energy and Energy Conservation" POI 2007-2013. In the Mondragone area hydrothermal evidences has been known since roman time, and this area has been chosen to further improve geothermal knowledge through new geophysical and geologicaI exploration survey. From the geological point of view, the area is defined by an horst structure (Mt. Massico) elongate in NE-SW direction, characterized by a succession of Triassic-Cretaceous dolomitic Iimestone and Miocene terrigenous sediments. The Quaternary deposits are widespread in the adjacent plans, where the continental and marine sediments, interbedded with Roccamonfina and Campi Flegrei pyroclastic deposits, filling the Garigliano, to NW, and Volturno, to SE, graben, separated by the Mt Massico horst throught a NE-SW striking normal faults (Bergomi et al., 1969). Field and seismic data indicate the study area is interested by deep normaI NE-SW and N-S striking faults, although ESE-WNW to E-W strike-slip left-Iateral faults are also present (Billi et al., 1997; Bruno et al., 2000). Probably these structural pattern plays an important role for the Mt. Massico groundwater circolation, partially confining such structure from the less permeable deposits of plains, and allowing the groundwater to f10w primarily to the aquifer of the Garigliano plain (Allocca et al., 2005). At the southeastern edge of the massif four sulfur hot springs with temperatures between 22°C and 50°C emerge. In particular two hot springs, ("La Calda" and "Della Salute", up to 50°C and 29°C respectively) are located at the foothill of the Miocene terrigenous succession of Mt. Pizzuto, closely to the coast (Bergomi et al., 1969, Corniello, 1988). While the other two ("S. Giuseppe" and "Mt. Petrino solforosa" up to 22°C and 28°C respectively) are located at the foothill of the Mt. Petrino carbonatic structure (Trumpy & Manzella, 2009). According to some authors, the hot springs are fed by groundwater carbonate aquifer, where the water is heated and enriched of endogenous gas (CO2 H2S), rising along the extensive and deep tectonic discontinuity present, further testified by the morphological evidenced (sinkholes) found all along the southeastern edge of the Mt Massico (Del Prete et al., 2004). Moreover the different temperatures and degrees of mineralization of the four springs are interpreted as closely Iinked to the rising speed and water-rock contact time (Corniello, 1988; Allocca et al., 2005). A delimited area of 20 km2 south-east of Mt. Massico has been chosen to be studied by means of geological and geophysical surveys and deep drilling to provide analytical information useful to develop an hydrogeological 3D model that will allows the application of technologies for direct explotation of heat from geothermal source.

This report shows barriers and opportunities for geothermal development in countries, participating in ERANET Geothermal energy. These barriers and opportunities have been identified by the participants of ERANET Geothermal energy. They will be an important input in setting up a programme of international collaboration., FP7

Geothermal power generation has its roots in Europe, where the first test in 1904 and the real beginning of power generation in 1913 took place, both at the Larderello dry steam field in Italy. Since then, the development of geothermal technology has been continuous and the total installed capacity in Europe currently amounts to 1.8 GWe, generating approximately 11.5 TWh of electric power every year. For a decade, thanks to the optimisation of the new binary system technology, geothermal electricity can be produced using lower temperatures than previously. Moreover, with Enhanced Geothermal Systems (EGS), a breakthrough technology proven since 2007, geothermal power can in theory be produced anywhere in Europe. The main benefits of geothermal power plants are provision of base-load and flexible renewable energy, diversification of the energy mix, and protection against volatile and rising electricity prices. Using geothermal resources can provide economic development opportunities for countries in the form of taxes, royalties, technology export and jobs. The potential of geothermal energy is recognised by some EU Member States in their National Renewable Energy Action Plans (NREAPs). However, the actual potential is significantly larger. In order to increase awareness, GEOELEC - an IEE project co-financed by the EU and running between 2010 and 2013- has assessed and presented for the first time the economic potential in Europe in 2020, 2030 and 2050. The figures are quite impressive, showing the large potential of geothermal and the important role it can play in the future electricity mix., GEOELEC - IEE, {"references":["EGEC Market Report 2013/2014","EGEC Market Report 2012","AGEA-AGEG, 2008.
