Core-log-seismic integration in hard rock (since 2017)

Core-log-seismic integration (CLSI) is an interdisciplinary strategy, integrating core logging, downhole logging and seismic data, to reduce the key uncertainties associated with formation evaluation. The combination of core, log and seismic measurements merges lab data on samples with in situ logging information and bridges scales from the sub millimetre-scale of core investigations to the decimetre scale of logging data and ultimately the metre to kilometre scale of seismic data. The project aims to investigate the geophysical properties of the rocks from Seve Nappe Complex at the COSC-1 borehole (Sweden) and nearby areas and to establish a high-resolution seismic stratigraphy using a cross-disciplinary approach.
