Abstract
Despite the on-going downturn of oil price, exploration seismic techniques still make great progress, which leads to a huge increase in the amount of seismic data and further poses significant challenges to quality control (QC) and archiving of seismic data processing results. Quality control for processing results plays an important role in quality assurance of the data to be archived. Based on the analysis of challenges brought by massive data volumes, QC method of verifying stack and migration for seismic processing results was proposed to ensure the archives quality. Stand-alone QC strategy was proposed to avoid the time-consuming data I/O process and corresponding stand-alone QC software was also developed. Application examples of the proposed QC method in a western-China oilfield show the applicability and effectiveness in improving the efficiency of the QC workflow and in reducing the number of problems found in further interpretation and archives reuse process.
