Seismic interpretation

Seismic reflection is widely used in exploration, both at sea and on land, regardless of the geological context. Although it was initially developed by the oil industry, it is 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 the sedimentary, structural and fluid objects identified on the 2D and 3D seismic profiles. Particular attention will be paid to the resolution of the interpretation according to the initial data.

Using 2D and 3D seismic data, students will be given a step-by-step interpretation project to provide an initial integrated assessment drawing on their previous geological knowledge. All interpretation will be carried out on an interpretation station 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 basis for error-free interpretation, i.e. avoiding classic pitfalls such as object size problems and their resolution.
The datasets will be adapted to the training course, so as to best match the pedagogical objectives of the Masters programs from which the students come.
Skills covered by the course:
> Understanding the spatial and temporal representation of seismic data
> Performing horizon and fault propagation
> Understanding and interpreting seismic attributes
> Characterizing sedimentary and structural objects in map and cross-section
> Making correlation maps and interpreting them in the time domain
> Establishing and representing tectonic-sedimentary relationships
> Presenting an initial integrated geological assessment.
