Julien Meunier Geophysical Advisor for CGGVeritas Announces Presentation at SEG/EAGE DISC (Austria)

Julien Meunier, Geophysical Advisor for CGGVeritas Land Acquisition, draws on forty years of seismic acquisition experience to present this year’s SEG/EAGE Distinguished Instructor Short Course (DISC).

Julien will be presenting the 2011 DISC at the EAGE convention in Vienna on Thursday 26 May as part of his 30-stop worldwide tour. The title of this year’s DISC is Seismic Acquisition from Yesterday to Tomorrow.

The course offers insight into the history of seismic acquisition and the possible directions it’s heading in the future. It discusses the development of seismic acquisition as a result of the recent and dramatic acceleration in the evolution of technology. Offshore, wide-azimuth surveys are producing images of remarkable clarity. On land, the increase in channel count has led to the use of denser grids leading to significant noise reduction. Both onshore and offshore, the race for bandwidth extension is tenser than ever.

The course presents these developments as a natural consequence of the combination of the advances of technology and our need for clearer seismic images. The focus of the course is on the relationship between acquisition parameters and seismic image quality. It includes a historical overview and an elementary theoretical recap as well as discussing signal and noise, components of seismic acquisition, vibroseis, which is a very special source in itself, and acquisition geometry/survey design.

The goals of the course are to provide participants with:

– The ability to distinguish between signal and noise (at least in most cases)

– An understanding of the available “leverage” on signal and noise (as well as the leverage that is not available)

– Most importantly, the understanding that there is a relationship between acquisition parameters and seismic image quality and, ideally, increase knowledge of this relationship.

Julien says: “The course is ideal for anyone interested in seismic imaging. Interpreters would benefit from greater familiarity with acquisition (and processing techniques) as it would help them understand any shortcomings in the images they have to interpret. Acquisition specialists should also enjoy an unfamiliar presentation of familiar concepts. Processing geophysicists may learn more about the different types of interference in seismic images. Finally, the people who pay for these images may understand why they are so expensive! “

Being asked to present the 2011 DISC comes as a fitting tribute to Julien’s tireless dedication to geophysical innovation during a career spanning nearly forty years with CGGVeritas. During that time Julien has worked in a number of key acquisition areas such as shallow water acquisition, 4D monitoring, including the development of SeisMovie with Gaz de France and IFP, 3D acquisition geometry and Vibroseis acquisition, including the development of HPVATM and V1TM. Julien has also been granted numerous patents and presented many papers on these techniques. He also took part in the EAGE Distinguished Lecturer Program in 2005.

Julien is a Fellow in the CGGVeritas Technical Community. A Fellow is the highest level in the company’s Expertise Ladder and is a distinction bestowed on technical staff having developed industry-leading technology and achieved worldwide recognition for technical innovation.
