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

<div>Measured (dotted) and calculated pressure (solid) vs. square root of time of the Detfurth (red) and the Solling (green), for the two limiting fracture lengths 2x<sub>f</sub> = 1000 m and 2000 m and Detfurth transmissivity T<sub>D</sub> = 1.5·10<sup>-14</sup> m<sup>3</sup>. Calculated flow rate records of the Detfurth sandstone (red) and the fracture (blue) for the same parameters as left.</div>
