Tools for Seismic Reservoir Characterization: Post-Stack Seismic InversionRCM/POSTSTACK

Who should attend?

  • This course makes participants able to perform a post-stack seismic inversion, QC and interpret the results, in order to finally detect and quantify lithologies, porosities and fluid content using seismic amplitudes and well information. This training can be followed by the “Tools for seismic reservoir characterization: Pre-Stack Seismic inversion” session (page 116) to complete inversion technique skills.
Audience :
  • Geophysicists, and senior/junior geoscientists with a solid seismic background knowledge.

Level : Advanced

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • run a feasibility study for seismic post-stack inversion,
  • prepare and load data for seismic post-stack inversion,
  • run and supervise a seismic post-stack inversion,
  • perform quality control and interpret the results.

Ways & Means

  • The training will be performed in workshop mode, using a standard case study. Interactive presentations, exercises, document analysis will help to understand the key steps.
  • Dedicated industry software will be used for this training.
