Short summary
A workflow is presented that uses 3D subsurface image (seismic) data to identify and avoid potential geological hazards, in order to increase safety and minimize the risk associated with selecting offshore scientific drilling locations. The workflow has been implemented for a scientific drilling expedition proposal within a challenging region offshore north-western Greenland and resulted in an improved understanding of subsurface hazards and a reduction of risk across all selected drill sites.
