WP1 PROJECT MANAGEMENT AND COORDINATION
The project management is organised to efficiently coordinate the project and to ensure that the appropriate procedures are implemented to achieve its targets within the established timeframe and budget. The energy company HS Orka will coordinate the DEEPEGS project. The appointed coordinator is Dr. Gudmundur O. Fridleifsson, he is an experienced project manager, and has been to project leader for the IDDP consortium for 15 years.
WP2 INTEGRATION, CROSS-CUTTING SYNTHESIS OF RESULTS
is the technical integration and synthesis work package and its role is to bring regularly together the partner teams to review progress and implementation of different technologies. The exchange of expertise and know-how generated in the development and implementation of the demonstrators will be synthesised into deployment practices and generation Standard Operating Procedures (SOP) needed to implement any lessons learned and prepare working documents to be taken up by WP3 for advancing the generation of business concepts, e.g. the life cycle perspective analysis, and validation of economics data from WPs 6-8 in particular, but as well WPs 4 and 5.
WP3 BUSINESS STRATEGIES AND EXPLOITATION
is the work package responsible for developing the business models and plans for future exploitation and market pilots. This work also incorporates the risk assessment information, environmental information, and life cycle perspective analysis information and uses this for implementing hazard mitigation actions. Communications addressing society concerns are prepared and in connection with WP9 are targeted to different stakeholders to improve awareness and public acceptance of EGS, and inform about benefits for general energy security and potential for job creation impacts e.g. via arising geothermal resource park opportunities. Open days / workshops at the three demonstrators are used to raise market interest and motivate future wider deployment opportunities. The technical innovations are managed through WPs 4-8, where the innovation and research activities developed in DEEPEGS will be focused on specific points highly relevant for EGS development.
WP4 SCIENTIFIC METHODOLOGY
In deep geothermal systems that could be operated as EGS, one of the main problems is usually to obtain adequate productivity and / or injection capacity of wells. In general, this is related either to a total lack of permeability at a large scale, or to a high degree of heterogeneity in permeabilities in relation to the deep structures and/or to too small local permeabilities. To be able to generalize the exploitation of deep heat, these cases must be addressed through appropriate methodologies. This work package aims to implement methodologies appropriate to the different exploitable sites and to define development scenarios.
WP5 SCIENTIFIC METHODOLOGY
For harnessing geothermal energy robust and well-trusted technologies are required for e.g. drilling, casings and couplings. This becomes even more critical when drilling deeper to create EGS, where conditions may become critically harsh for conventional technologies and materials used. This WP will mobilise work needed to improve available technologies and test new ones like e.g. mud-hammer and casings materials and couplings capable of withstanding harsher conditions arising in deep EGS situations. Also adaptation for geothermal implementations and transfer of technology from oil and gas industry will become important to encounter potential lack of permeability and “Fishbone” / Multi-drain drilling will need to be implemented.
WP6 SCIENTIFIC METHODOLOGY SPECIFIC FOR REYKJANES
In the Reykjanes system the approach is relatively simple as previously shown by the conceptual model in Fig. 2. The intention is to directionally drill a deeply cased well into/and underneath the exploited geothermal system. The production casing will be set at approximately 3 km depth, while the producing section of the well will be drilled to about 5 km depth. Most of the overlying production wells are 2–2,5 km deep with production casings to around 800 m depth. The temperature range in the production wells is 270-320°C. The temperature at 4-5 km depth is expected to range between 400-500°C, with a potential maximum of 550°C. From previous seismic studies the brittle/ductile boundary in the basaltic host rocks is expected at some 7 km depth, with temperatures of 650-750°C.
WP7 SCIENTIFIC METHODOLOGY SPECIFIC FOR VALENCE
The Valence’s demonstrator will be the first and the main one developed in France by DEEPEGS. The first development (especially technical and administrative rules and regulations) will be done from the beginning of the project. We expect to have completed execution of the project in three to four years. Soon after end of the DEEPEGS project we expect to connect the wells to a geothermal power plant in order to reach a commercial phase operation. The first drilling is expected in month twelve (M12) During the drilling phase a new mud-hammer tool will be tested. After drilling, and in accordance to the well monitoring, we anticipate being able to implement the multi-drain drilling method (or fishbone drilling). We expect that by two or three multi-drain boreholes (or side-track boreholes) we will improve the permeability performance of the well by higher fluid output. If successful the remaining consideration rests with the economy of such multi-drain systems for the local community. In Valence, the target will be Triassic sandstone and Basement rocks at 4500-5500 m depth, both of which are fractured The primary permeability of these formations is low and without the karst phenomenon. For that reason, Fonroche aims to drill through the main faults in order to get good secondary permeability.
WP8 SCIENTIFIC METHODOLOGY SPECIFIC FOR VISTRENQUE
The Vistrenque’s demonstrator will be the second one in operation in France, and drilling and EGS work will start during latter part of the Valence activities in DEEPEGS. In this area according to our first studies we have already conducted, the plan is to implement a new technology based on the multi drain drilling technology and stimulation for increasing permeability. We expect to do perform the first drilling operations in month 30, or just after the second well in Valence will be completed.
WP9 DISSEMINATION, STAKEHOLDER OUTREACH AND COMMUNICATIONS
The main aim of WP9 is to ensuring adequate and wide scale dissemination and outreach to stakeholders regarding the project developments on three levels:
- Dissemination actions
- Outreach to key stakeholders for consultations on the DEEPEGS results and impacts
- Develop a Policy Roadmap for the widespread deployment of deep geothermal enhanced energy systems
WP9 will thus act as an interaction and dissemination platform and the external community interested in renewable energy systems. A number of activities have been foreseen in order to ensure the best exchange of knowledge and experience generated in DEEPEGS between the project partners, together with all relevant stakeholders (e.g. Governmental departments, policy managers, NGOs, research organisations, associations, energy companies, resellers, grid managers, educational/training institutions, etc.) both on the European and the global scale. Contribute, upon invitation by the Innovation and Networks Executive Agency (INEA), to common information and dissemination activities to increase synergies between, and the visibility of H2020 supported actions.
