The COMPASS project is inspired by global efforts to improve utilization of geothermal resources by enlarging production fields downwards. Energy output can be enhanced, without the need to expand surface infrastructure, by drilling into deep and hot formations. Calculations indicate that wells drilled into superhot conditions will yield 5-10 times more than a conventional well which can significantly reduce number of wells required. The main challenges to achieve this are related to the well integrity; due to extreme temperature changes and corrosive fluid chemistry encountered. Two of three wells in the Iceland Deep Drilling Project (IDDP) have already been drilled and had serious problems with casing failures. Numerous examples of casing failures in conventional geothermal wells show that current well concepts, mainly transferred from oil and gas applications, are barely sufficient for geothermal use. COMPASS will address these challenges by developing improved and innovative well casing technologies: -To mitigate casing failures, novel foam cement solutions will be developed suitable for high temperature formations. This system would work with available flexible couplings to mitigate high-temperature induced stresses and ensuring well integrity. - Cost-effective laser-cladding will be used to improve corrosion protection inside the casing pipes. These technology developments will be enhanced with a robust well design solution addressing challenges, reducing project risk and enabling reduction of LCOE. The new well concept will enable cost-effective geothermal developments in new types of geological settings and new regions. The COMPASS consortium contains a diverse team of major geothermal research institutes and leading industry players. This combination ensures cross-fertilisation, sharing of knowledge and experience, and seamless transfer of the novel well construction technologies by industry application, including significant citizen e

Compass Project的灵感来自全球通过向下扩大生产领域来改善地热资源利用的努力。通过钻入深层和热的地层，可以增强能源输出，而无需扩大表面基础设施。计算表明，钻入超级跑步条件的井比常规井的产生5-10倍，这可以显着减少所需的井数。实现这一目标的主要挑战与井的完整性有关。由于温度的极端变化和腐蚀性流体化学反应。冰岛深钻探项目（IDDP）中的三口井中的两个已经进行了钻探，并且在套管故障方面遇到了严重问题。常规地热井中壳体故障的许多例子表明，当前主要是从石油和天然气应用转移的井概念几乎不足以用于地热使用。 Compass将通过开发改进和创新的套管技术来解决这些挑战： - 为了减轻套管故障，将开发出适合高温形成的新型泡沫水泥解决方案。该系统将与可用的柔性耦合一起使用，以减轻高温引起的应力并确保良好的完整性。 - 具有成本效益的激光层将用于改善套管管道内部的腐蚀保护。这些技术开发将通过解决挑战，降低项目风险并降低LCOE的强大设计解决方案来增强这些技术的发展。新的井概念将使新型地质环境和新区域中具有成本效益的地热发展。 Compass Consortium包含一个多样化的地热研究机构和领先的行业参与者团队。这种组合确保了跨批准，知识和经验的共享以及通过行业应用的新颖井建筑技术的无缝转移，包括重要的公民
