Description

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

Objectives

From 2D and 3D seismic data, students will have a step-by-step interpretation project to provide a first integrated assessment using their previous geological knowledge. The whole interpretation will be done on an interpretation station with dedicated software from the industry (Kingdom and Petrel). Although the training of a good seismic interpreter generally requires several years, the objective of this module is to provide the concepts and the basis for an error-free interpretation, i.e. avoiding the classical pitfalls such as object size problems and their resolution.
The datasets will be adapted to the training in order to best fit the pedagogical objectives of the Masters from which the students come.
Competences aimed by the UE :
> To understand the spatial and temporal representation of seismic data
> To carry out a propagation of horizons and faults
> To understand and interpret the seismic attributes
> To characterize the sedimentary and structural objects in map and section
> To carry out correlation maps and to interpret them in the time domain
> To establish and to represent the tectonic-sedimentary relations
> To present a first integrated geological evaluation
