dc.description.abstract | The interpretation of seismic data is an integrated process that requires geophysical knowledge and an intuitive geological understanding. While seismic interpretation is essential in order to accumulate knowledge and build an understanding of the subsurface, some elements of the interpretation workflow can be tedious, subjective and in some cases even trivial. In this thesis, we present data-driven methods that seek to integrate data science and geoscience in order to address different aspects of automated seismic interpretation. The data-driven methods that we present are based on digital tools from image processing, signal processing and machine learning. With these methods, we aim to (1) identify and individualize faults and unconformities, (2) correlate and track non-coherent seismic horizons, (3) identify stratigraphic units and (4) improve seismic image quality. | en_US |
