Workshop Description

In seismic processing, most imaging and inversion schemes are formulated under the assumption that single-scattered events are signal and all other events are noise. Within this paradigm, accurate removals of free-surface and internal multiples are required in the data conditioning steps. Recent advances in methods for internal multiples elimination have indicated potential for much improved imaging results in a variety of synthetic and field data scenarios. 

In other research developments, sub-events from multiples or sub-sets of multiples are considered as signal within imaging or inversion methods. While most of this work has focused on utilizing free-surface multiples as signal, there are also methods that aim to use internal multiples as signal in imaging, inversion or velocity model building.

In this workshop we will discuss recent research advances on internal multiples with the goal of understanding pre-requisites, potential, and limitations of current methods, with respect to both theoretical and practical aspects, as well as the interrelationship between current methods. We will have four mini-sessions in the workshop, starting with three sessions on advanced prediction methods (including Inverse Scattering series and Marchenko approaches; methods that make use of subsurface velocity models, and methods that jointly address multiples and velocity model building). The last mini-session of the workshop will focus on the inclusion of advanced prediction methods in practical workflows both in terms of operational challenges and in meeting requirements and expectations for improved quality of the results. 

Workshop Format

This full-day post-convention workshop will consist of four mini sessions, each including three to five oral presentations (20 min each) and time (20 min) for questions and discussion.
