New concepts for high-temperature geothermal well technologies are strongly needed to accelerate the development of geothermal resources for power generation in Europe and worldwide in a cost effective and environmentally friendly way. The GeoWell project will address the major bottlenecks like high investment and maintenance costs by developing innovative materials and designs that are superior to the state of the art concepts. The lifetime of a well often determines the economic viability of a geothermal project. Therefore, keeping the geothermal system in operation for several decades is key to the economic success. The objective of GeoWell is to develop reliable, cost effective and environmentally safe well completion and monitoring technologies. This includes: - Reducing down time by optimised well design involving corrosion resistant materials. - Optimisation of cementing procedures that require less time for curing. - Compensate thermal strains between the casing and the well. - Provide a comprehensive database with selective ranking of materials to prevent corrosion, based on environmental conditions for liners, casings and wellhead equipment, up to very high temperatures. - To develop methods to increase the lifetime of the well by analysing the wellbore integrity using novel distributed fiber optic monitoring techniques. - To develop advanced risk analysis tools and risk management procedures for geothermal wells. The proposed work will significantly enhance the current technology position of constructing and operating a geothermal well. GeoWell aims to put Europe in the lead regarding development of deep geothermal energy. The consortium behind GeoWell constitutes a combination of experienced geothermal developers, leading academic institutions, major oil&gas research institutions and an SME. These have access to world-class research facilities including test wells for validation of innovative technologies and laboratories for material testing.

Our goal with the DEEPEGS project is to demonstrate the feasibility of enhanced geothermal systems (EGS) for delivering energy from renewable resources in Europe. Testing of stimulating technologies for EGS in deep wells in different geologies, will deliver new innovative solutions and models for wider deployments of EGS reservoirs with sufficient permeability for delivering significant amounts of geothermal power across Europe. DEEPEGS will demonstrate advanced technologies in three geothermal reservoir types that provide all unique condition for demonstrating the applicability of this tool bag on different geological conditions. We will demonstrate EGS for widespread exploitation of high enthalpy heat (i) beneath existing hydrothermal field at Reykjanes (volcanic environment) with temperature up to 550C and (ii) very deep hydrothermal reservoirs at Valence (crystalline and sandstone) and Vistrenque (limestone) with temperatures up to 220C. Our consortium is industry driven with five energy companies that are capable of implementing the project goal through cross-fertilisation and sharing of knowledge. The companies are all highly experienced in energy production, and three of them are already delivering power to national grids from geothermal resources. The focus on business cases will demonstrate significant advances in bringing EGS derived energy (TRL6-7) routinely to market exploitation, and has potential to mobilise project outcomes to full market scales following the end of DEEPEGS project. We seek to understand social concerns about EGS deployments, and will address those concerns in a proactive manner, where the environment, health and safety issues are prioritised and awareness raised for social acceptance. We will through risk analysis and hazard mitigation plans ensure that relevant understanding of the risks and how they can be minimised and will be implemented as part of the RTD approaches, and as a core part of the business case development.

The IMAGE project will develop a reliable science based exploration and assessment method to IMAGE geothermal reservoirs using an interdisciplinary approach based on three general pillars: 1 Understanding the processes and properties that control the spatial distribution of critical exploration parameters at European to local scales. The focus will be on prediction of temperatures, in-situ stresses, fracture permeability and hazards which can be deduced from field analogues, public datasets, predictive models and remote constraints. It provides rock property catalogues for 2 and 3. 2 Improving well-established exploration techniques for imaging and detection beyond the current state of the art and testing of novel geological, geophysical and geochemical methods to provide reliable information on critical subsurface exploration parameters. Methods include a) geophysical techniques such as ambient seismic noise correlation and magnetotellurics with improved noise filtering, b) fibre-optic down-hole logging tools to assess subsurface structure, temperature and physical rock properties, and c) the development of new tracers and geothermometers. 3 Demonstration of the added value of an integrated and multidisciplinary approach for site characterization and well-siting, based on conceptual advances, improved models/parameters and exploration techniques developed in 1 and 2. Further, it provides recommendations for a standardized European protocol for resource assessment and supporting models. The IMAGE consortium comprises the leading European geothermal research institutes and industry partners who will perform testing and validation of the new methods at existing geothermal sites owned by the industry partners, both in high temperature magmatic, including supercritical, and in basement/deep sedimentary systems. Application of the methods as part of exploration in newly developed fields will provide direct transfer from the research to the demonstration stage.
