W-13: Improving Data Quality in Noisy Land Areas

SEG 2012 Annual Meeting Technical Program

Date: Friday, 9 November 2012
Time: 8:30 am – 4:00 pm        
Location: Mandalay Bay Convention Center, Room: Breakers H
Organizers: Qunshan Zhang, Ran Bachrach, Oswaldo Davogustto Cataldo (student), and Christine Krohn
Through the support of the SEG Research Committee   

Description
 

In some areas, dramatic data quality improvements have been made in land seismic data with the recording of high channel count and using single sensors and single sources technology. In other areas, near-surface related noise is still a major industry challenge. 

This workshop will explore methods to mitigate the noise in acquisition and in processing as well as the need for field arrays in some areas. New methods and case studies will be presented and examples of how noise relates to near-surface properties and heterogeneities will be discussed. 

In addition, participants in the SEAM II project will discuss the challenges of building realistic models for land seismic data in different environments, including unconventional reservoirs (complex stratigraphic models), arid areas(strong scatterers and karst), and foothills (extreme topography & strong lateral velocity variation).
