%T Hydraulic Characteristics of the Basel 1 Enhanced Geothermal System
%X This paper characterizes the hydraulic properties of the
Basel 1 enhanced geothermal system. The increase in reservoir permeability and the change of the dominant flow regime due to the massive stimulation in 2006 are evaluated with temperature measurements and low pressure hydraulic tests. The reservoir permeability was found to be increased by two orders of magnitude and the dominant flow regime changed from bilinear to linear flow. The findings from hydraulic well testing are supported by microseismic data analysis indicating a stimulated reservoir that evolved along a distinctive fracture zone.
