Mixing Unsupervised and Knowledge-Based Analysis for Heterogeneous Object Delineation in Seismic Data

Summary Seismic interpretation is increasingly supported by quantitative, partly-automated methods. For economic purposes, some geological objects (geobodies) are targeted for automated delineation in seismic data. Some of them are depicted by a variety of internal seismic facies. Geobody detection is often based on the supervised retrieval of a defined seismic facies. It usually assumes homogeneous properties inside the targeted object....
