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.
