Abstract:Five seismic data acquisition surveys were conducted recently in Ordos Basin.Based on characteristics of the data,we built a processing workflow with different tools provided by GeoEast,and processed the seismic data.The key processing techniques include:prestack noise suppression,offset vector tile (OVT),velocity model building,and prestack depth migration.High-quality stack,migration,and different azimuth stack data are obtained.Our processing results show that GeoEast processing approaches achieve good success,which provides an excellent foundation for prestack inversion,structural interpretation,and fracture prediction.
