Today's Exploration seismic data quality requirements for early detailed geophysical reservoir characterization, baseline time-lapse surveys and fluid characterization have been largely satisfied by the technological advances in seismic acquisition. This then followed-up by first pass conventional processing sequence, including inadequate QA/QC and project management renders obsolete the time and effort put into the planning and executing of the seismic survey in the first place, as the processing results will be no better than a conventional exploration shoot, where the main objective typically is coverage and structural definition. This paper deals with experiences from a recent 3D acquisition, first pass processing which was followed by a focussed reprocessing sequence. The latter performed by a multidisciplinary team comprising various levels of expertise from client and contractor. This paper will discuss how the more relevant advances in the application of concepts, models, techniques, workflows and decision processes related to the supervision of seismic data processing, with focus on initial detailed scope definition, contract management plan, team composition and communication protocol, detailed technical meetings and deliverables, QA/QC processes and sign-off, produced a better output in today's seismic processing project.. |
