Seismic interpretation

Reflection seismics are widely used in exploration, both offshore and onshore, regardless of the geological context. Although initially developed by the oil industry, they are now used by industry (oil and mining) as well as by research and design offices. It can be deployed to image the subsurface on both a local and regional scale. Students will therefore learn to interpret sedimentary, structural, and fluid features identified on 2D and 3D seismic profiles. Particular attention will be paid to the resolution of the interpretation based on the initial data.

Using 2D and 3D seismic data, students will carry out a step-by-step interpretation project to provide an initial integrated assessment drawing on their prior knowledge of geology. The entire interpretation will be carried out on an interpretation workstation using dedicated industry software (Kingdom and Petrel). Although it generally takes several years to train a good seismic interpreter, the aim of this module is to provide the concepts and foundations for error-free interpretation, i.e., avoiding classic pitfalls such as object size issues and their resolution.
The datasets will be adapted to the course to best suit the educational objectives of the Master's programs from which the students come.
