dc.description.abstract Seismic stratigraphy analyzes the geological concepts of stratigraphy by identifying the seismic reflection termination patterns that may record stratal terminations such as onlaps, downlaps, erosional truncations, and toplaps. It is a common tool in the assessment of source reservoir and seal rocks during petroleum system analysis in a basin. However, identifying the reflection termination patterns on seismic sections line-by-line is a time-consuming task. This study demonstrates a new workflow for picking sequence-bounding surfaces semi-automatically using seismic waveform, acoustic impedance, and porosity attributes. During this study, the workflow started with a process of selecting seismic attributes, followed by a manual interpretation of sequence boundaries on key seismic lines. The key lines are treated as control points for the semi-automatic seismic interpretation. Finally, the sequence boundaries are semi-automatically picked by finding the shortest path defined by multiple seismic attributes. To test the effectiveness of this workflow, I used a 3D seismic data set acquired over the Dutch sector of the North Sea. The workflow successfully traced the sequence boundaries between manually interpreted horizons.
