This case study is based on an industrial data set provided by one of our sponsors. We demonstrate the possibility of processing and interpreting hydraulic fracturing induced microseismicity with a low signal/noise ratio obtained from a restricted acquisition geometry. We provide work-flows for microseismic event localization as well as for determining fracture geometry and estimating hydraulic transport properties.

We aim to image subsurface geologic structures across the San Andreas fault system in South Central California. Old industry seismic reflection data are reprocessed and imaged with advanced prestack migration techniques in order to produce new seismic images down to the lower crust.

During several student excursions of the FU Berlin, geoelectric investigations were carried out in the SW of the German Continental Deep Drilling (KTB) site across the Franconian Lineament (Fränkische Linie), which separates the sedimentary (Mesozoic) foreland from the crystalline nappe of the Zone Erbendorf-Vohenstrauss (ZEV). A strong negative self- potential anomaly was found to run parallel to the fault zone, reaching values of up to -800mV. A DC-geoelectric sounding was conducted along ...
