Course OverviewThe objective of this course is to provide

the attendees with a practical background

in seismic processing through a series

of lectures and practical exercises. The

course is built around processing a 2D

marine seismic line from field records

through to a final migrated image. The

attendees will gain hands-on experience as

they process the data themselves tackling

the common workflows and problems that

arise during a processing project.

By comparing the parameter choices

made and results obtained by all of the

attendees at each processing stage, critical

parameters and quality control issues can

be identified and discussed, including

limitations on processing methodology and

processing artefacts.

Course TutorsGuy Maslen is has been a seismic data

processor for 14 years and is currently

GNS Sciences’ Commercial Processing

Manager. Prior to joining GNS Science

Guy worked for in Europe for Veritas

and CGG, including 2D/3D marine and

land processing, on-board processing

and depth imaging. Guy has a MSc is

Applied Geophysics from the University of

Birmingham.

Dr. Tony Harrison joined GNS Science in

2005, but has over ten years experience

in using GLOBE Claritas at a variety

of locations. Tony currently combines

commercial project processing with

providing support and advice to GLOBE

Claritas users worldwide. Tony has a MSc

in Applied Geophysics from the Victoria

University and a PhD from the University

of Cambridge.

Course Content • Overview of seismic processing theory :

the convolutional model

• Marine processing : methodology

and objectives

• Initial quality control checks on data

• Pre-processing shots to remove noise

• Deconvolution : deterministic

and predictive

• Seismic velocity analysis

• Mutliples and their suppression

• Imaging and Finalisation

• 3D processing overview

• Land processing overview

Course MaterialsThe course materials comprise 190+

powerpoint slides spread across 9 modules

and a workbook for the practical sessions.

The workbook also includes additional

reference material, including a guide to

marine acquisition terminology.

The practical sessions are conducted

using GNS Sciences’ GLOBE Claritas

seismic processing software, and have

been developed with supporting parameter,

processing flows and support files so that

the primary focus for the attendees is on

the practicalities of processing rather than

learning how to use the software.
