Abstract:A crooked wide line seismic acquisition was carried out in the working area M, Weihe Basin. Due to complex surface and near surface, a great number of serious problems are faced for data processing such static corrections, many kinds of interference, and low S/N ratio. On the other hand, complex structure and developed faults make data imaging more difficult. We reprocess the data using a set of approaches provided by GeoEast such as crooked wide line geometry definition, multi static corrections, prestack amplitude-preservation denoising, and crooked line prestack time migration. Compared with the previous processing, the imaging quality and the S/N ratio are significantly improved.
