Solutions for the energy-efficient use of the subsurface

All work steps can be analyzed for economic and operational risks for predictive risk minimization and monitored by our specialists using innovative sensor and measurement techniques. In close cooperation with industry, we develop innovative thermal, hydraulic, and mechanical drilling methods and bring them to industrial application. For example, our patented microturbines can be used to upgrade existing production wells and develop reservoirs laterally and over a large area. We also develop structural, mechanical, and hydrochemical reservoir models based on geophysical subsurface data, laboratory tests, and borehole geophysical measurements. The analyses are supplemented by field tests, production and injection tests of the hydraulic properties of the deposits and reservoirs, and borehole geophysical measurements to assess the integrity of existing wells. 

In our geotechnical laboratory, additional tests can be carried out on borehole materials, reservoir rocks, and fluids in order to optimize their use and reduce production risks. To this end, we implement condition monitoring procedures using acoustic sensors and mathematical codes for the self-learning control of drilling, reservoir, and energy technology processes. Our experts work with you to plan and implement shallow to medium-depth geothermal probes for individual or grid-connected heat supply. Fraunhofer IEG also has its own 40-ton drilling rig, which can be used to drill holes up to 1000 m deep and develop them into geothermal probes, production or injection wells. The Geostar developed by Fraunhofer IEG enables the installation of large-scale geothermal probe systems even in densely built-up areas. Our experienced drilling engineers coordinate planning, approval, and execution work for deep drilling projects and work with you to develop concepts for the reuse of existing boreholes and storage facilities for energy-efficient use and connection. Through our training programs, we prepare your company for its underground projects and provide you with the necessary expertise to plan and implement your projects.
