Abstract:Nowadays more and more seismic surveys are carried out in some places with lots of obstacles such as urban area, industrial area,oilfields,and others. The large number of obstacles causes seismic data lacking zones,which brings uncertainty of the follow-up seismic data processing and interpretation. We propose in this paper a few approaches to reduce seismic acquisition blank zones and improve data integrity such as receiver point multi-move positioning, automatic obstacle avoidance,and flexible operation safe distance calibration. Our practices show that these approaches achieve satisfactory results.
