DEmonstrate Production enhancement through LOw cost dIrectional steel shot drilling for district HEATing

The DEPLOI project concerns the Directional Steel Shot Drilling technology with which long multilateral structures can be drilled in shallow and deep geothermal reservoirs. The structures improve the reservoir contact such that production is boosted by a factor of 2.5 while well construction cost only increases by 20%.
The technology has been demonstrated in the drill test facilities of the TNO Rijswijk Center of Sustainable GeoEnergy (RCSG) and is ready for field trials.

The project includes constructing a prototype drilling service unit to be tested in two trials: in Switzerland (shallow Hagerbach test site in limestone) and the Netherlands (1600 m vertical depth in sandstone). The University of Calgary, Canada, is to model the drilling assemblies and monitor the drilling in real-time. TNO does the Final Acceptance Testing at the RCSG.
