Course Description

The topic of seismic multiples evolves continuously as a result of advances within its own field as well as changes in applications and related technologies. For many geoscientists, the topic may seem challenging to enter or to keep abreast of developments. This lecture is intended for professionals who are looking for a refresher on the topic of multiples in seismic processing and for an introduction to the latest research and technology developments.

Course Objectives

Upon completion of the course participants will have improved their familiarity with the technology and gained confidence in working with concepts related to multiples in seismic data processing.

Course Outline

The following steps will be discussed:

An outline of the ten stops on this guided tour of the topic of multiples in seismic data processing is as follows:

First session:

1. Examples of multiples in seismic data, definitions of multiples, numerical modeling, synthetics datasets.

2. Multiple scattering at different scales in acoustic experiments (VSP, sonic, sea-bed profiling, crosswell, sonic). Using VSP and sonic data to gain understanding of multiples in surface seismic data.

3. Multiples in model building and imaging seismic data processing workflows. Multiples as noise or as signal.

4. Prediction methods for free-surface multiples and analysis of their properties; data-driven and model-based approaches.

5. Adaptive subtractions and results assessment

Second session:

6. Signal processing transforms and their applications to multiples

7. Up-down deconvolution and inversion methods for sea-bed and streamer data

8. Prediction methods for internal multiples; perspectives from Marchenko and Inverse Scattering Series theories.

9. Case study examples: deep-water marine, shallow-water marine, land (based on published case studies).

10. Wrap-up: historical developments, trends, emerging technologies. For each of the ten topics above, there will be 20 min allocated, for a short presentation and time for questions and discussion. A handout and a reading list for each topic will be part of the material distributed before the class.

Participants' Profile

The course is designed for geoscientists who work with or have an interest in surface seismic data and wish to gain a deeper understanding of the technology related to multiples in seismic data.

Prerequisites

Basic knowledge of surface seismic surveys and their acquisition, processing, and applications.
