5 days RES/SEISATTRIB
Level
Proficiency
Audience
  • Junior geoscientists.
Purpose
  • This course aims to grasp the basics of seismic interpretation, both qualitative and quantitative methods. To be able to understand and follow every step of seismic interpretation projects.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • work effectively in a seismic interpretation study project,
  • understand how to perform a feasibility study and to select the most appropriate workflow,
  • gather and prepare data for seismic interpretation studies.
Prerequisite
  • No prerequisites for this course.
Ways and means
  • Interactive presentations, practical exercises, document analysis.
  • Workshop on case study using dedicated software.

Qualitative interpretation 1.5 days
