Abstract
Summary
A workflow has been designed to process different types of streamer acquisition for a single 4D survey. Undershoot data has been processed together with prime lines, but special attention has been made to ensure the undershoot data are consistent with prime lines after water column statics correction. A trapezoid filter has been used to optimally reject bad trace pairs by finding the compromise between DSDR and NRMS. Single boat data of different azimuths has been processed separately and merged post-migration. The processing workflow has been adjusted to accommodate two boat reverse push lines. The final 4D results have shown the effectiveness of the workflow.
