Who Needs Seismic Survey Quality Control?
— An Objective Approach By Andrea Collins1 (1) Exploration Consultants Limited, Henley-on-Thames, Oxon, United Kingdom There are many differing points of view with regard to the use of Independent Quality Control on seismic surveys. Sometimes it is not easy to be objective about this process when the whole picture may not be seen. The aim of this presentation is to provide those of you with experience in upstream or downstream operations with a fair, balanced view of Independent QC. It should be accepted that any process is not successful 100% of the time. Therefore it is advisable to check the output from each process or a sequence of processes. The check itself is another process and therefore has a success rate also, but the overall success is increased significantly. This concept can be likened to layers of paper superimposed upon one another each having a few randomly placed holes. The aim is to stack enough layers together so that there are no holes in the final combined product
