Predictability of properties of a fractured geothermal reservoir: the opportunities and limitations of an outcrop analogue study

Table 1 Wireline-logging tools used in this study

Tool	Log interval (MD) (m)	Measurements of	Evaluation of
GR	3305–3150	Natural gamma rays	Sand/clay content, depth correlation of the various logging tools
FMI	3295–3150	Electrical resistance, well caliper	Sedimentary facies, detection of open/closed fractures, fracture orientation, fracture intensity, fracture apertures
DSI	3293–3150	Compressional- and shear-wave velocities	Matrix porosity, elastic mechanical rock properties, lithology
LDS	3294–3150	Emitted gamma rays, Compton scattering and photoelectric absorption	Bulk porosity, bulk density, lithology

GR gamma ray, FMI formation micro imager, DSI dipole sonic imager, LDS litho density sonde, MD measured depth
