Determination of Hydraulic Properties of a Large Self-Propped Hydraulic Fracture in the Geothermal Research Borehole Horstberg Z1 in the Northwest German Basin

<div>Top: Steps for transforming the conceptual model of Figure <a href="../fig3/">3</a> into a 1D-model. Bottom: Scheme of the 1D-model. Q, QD, Qf, QS: total flow, flow into the Detfurth, the fracture, and the Solling, respectively. TD, Tf, TS, SD, Sf, SS: transmissivity and storage coefficient of the Detfurth, the fracture, and the Solling, respectively. Graph: scheme of the expected pressure profile, hf: fracture height, dS: horizontal distance between fracture and perforation in the Solling (see Figure <a href="../fig3/">3</a>).</div>
