Machine learning assisted seismic interpretation: An integrated workflow for structural/stratigraphic interpretation, combined with reservoir characterisation.
Introduction Interpretation of reflection seismic data has come a long way, from structural travel time interpretation, via stratigraphic amplitude and waveform driven interpretation, to full geobody extraction and quantitative interpretation of rock properties. Irrespective of the purpose of seismi...

Introduction Interpretation of reflection seismic data has come a long way, from structural travel time interpretation, via stratigraphic amplitude and waveform driven interpretation, to full geobody extraction and quantitative interpretation of rock properties. Irrespective of the purpose of seismic interpretation (e.g. regional exploration to field development studies), the main steps are mapping the structure of the subsurface layers and characterizing different properties of beds. A great deal of effort has been placed on finding new approaches to carry out seismic interpretation in semi- or fully automatic ways. Machine learning (ML) has contributed to more rapid and accurate data analysis in many disciplines including earth sciences. The latest developments in ML algorithms, high performance computing, and open source libraries, have enabled new and different workflows for petroleum data science including seismic interpretation. New workflows are more data driven and efficient, with improved measures of uncertainty. Method and Data Different ML approaches have been applied to individual steps of seismic interpretation.
