Results of a „low-rate“ injection test in September 2007. The interpretation of the shut-in phase after a step-wise injection into the Detfurth/Frac with flowrates < 2 l/s in the log-log-plot. The change of pressure (dP) and it’s deviation (dP’) show a fracture linear flow behaviour with an inclination of approximately ½ of dP and dP’Results of a „low-rate“ injection test in September 2007
