Abstract：A wide-azimuth 3D vibroseis survey was carried out recently in the GFZ area, Ordos Basin. We have processed this wide-azimuth 3D dataset with different tools provided by GeoEast. The key processing techniques include: tomo-static corrections, prestack noise suppression, high resolution processing, offset vector tile (OVT) processing, prestack time migration, and azimuthal anisotropy corrections. High-quality stacks, migrations, and different azimuth stacks data are obtained. Our application results show that GeoEast processing system achieves good success, which provides an excellent dataset for prestack inversion, structural interpretation and fracture prediction.
