 Zusammenfassung: Radial water Jet Drilling (RJD) is widely discussed in the geothermal community as a potential technology to stimulate low performing geothermal wells. For RJD, a focused water jet is being used to jet slim hole laterals out of an existing well in order to access (higher) permeable structures in the vicinity that were initially not well connected to the well or increase the contact area of the well with the formation. Based on the knowledge gained from laboratory experiments and numerical investigations, a workflow to select and stimulate a geothermal well and evaluate the radial water jet drilling technology is presented. The paper provides a discussion on preparations for a field test in Iceland in which a thorough monitoring approach istaken to gain a deeper understanding of the technology in the geothermal realm.
