The concept of shooting seismic sources in an overlapping and interfering way to increase productivity and quality while reducing costs has been around for some time. Since it was reintroduced in the late 1990’s this type of data acquisition and processing has received much attention and has progressed to the point that it is now an accepted method under many circumstances. This course will provide an introduction, based on the history of the subject, to the necessary concepts to understand the benefits as well as challenges that still remain for simultaneous source data. The course will strive to achieve a balance between the practical and theoretical issues and will finish with a look at recent innovations that indicate the near future of this exciting new paradigm in seismic data acquisition.
At the end of the course, the student should be able to:
The course is recommended for all geophysicists, reservoir geologists, seismic interpreters, and engineers concerned with reservoir characterization, reservoir delineation, hydrocarbon detection, reservoir development and recovery monitoring.
| Chapter I: The beginning
The cocktail party effect
Early land investigations
Marine seismic interference
More land investigations
| Chapter II: The reawakening
Marine simultaneous sources
Land and OBC simultaneous sources
| Chapter III: Towards Commerciality
Simulating simultaneous source surveys
First marine commercial simultaneous source survey
Simulation case studies
Simultaneous source QC
The big surprise: simultaneous sources are actually better!
| Chapter IV: Recent advances and the future
Improvements in separation algorithms
New acquisition sources and encoding techniques
| Chapter V: Workshop
My company wants to look at doing a simultaneous source survey. What is the recommendation?
The course will attract a wide variety of geophysicists with varied background. Some material is appropriate even for the non-geophysicist interested in the economics issues, however the ideal student will have a firm knowledge of conventional seismic acquisition and processing.
About the instructor
Craig completed B.S., M.S. and Ph.D. degrees in mathematics and then joined Western Geophysical 1981. He has spent his entire career in Schlumberger companies and their antecedents serving in various technical and management positions including VP for R&D and VP, Data Processing. He has received technical and honorary awards from entities such as Litton Industries, Schlumberger and the Society of Exploration Geophysicists, among them the SEG Award for Best Presentation. He has twice received honorable mention for the Best Paper in Geophysics. He is an Honorary Member of the Society of Exploration Geophysics (SEG) and of the Geophysical Society of Houston and is a Foreign Member of the Russian Academy of Natural Sciences. He has presented papers and published widely on a variety of topics ranging from prestack imaging, migration, acquisition and the connections between acquisition, processing and imaging. He pioneered Simultaneous Source technology and has recently worked in broadband seismic techniques and new methods for sparse inversion. He was the 2001-2002 SEG 1st Vice President and the 2004-2005 President of the SEG. He served as the Fall 2009 SEG Distinguished Lecturer as well as the Esso Australia Distinguished Lecturer and as 2014 EAGE Distinguished Lecturer. He was the Founding Chair of the SEG Committee for Geoscientists without Borders. He has enjoyed postings in Singapore and Rio de Janeiro and now is in Houston, recently retired as Chief Geophysicist for WesternGeco and Schlumberger Fellow (Emeritus). In retirement, he has served as the General Chair for the 2017 SEG Annual Meeting in Houston and sits on the board of the SEG foundation and is enjoying pursing his passion for underwater photography and video.
