Seismic processing for time-lapse study; Genesis Field, Gulf of Mexico



Seismic processing for time-lapse study; Genesis Field, Gulf of Mexico



The Leading Edge (Tulsa, OK) 24(4): 364-373



Extraction of the maximum resolution that the data will permit is the usual objective for optimal processing of a single seismic survey. Careful data analysis and appropriate choice of technology are key to achieve this goal. Processing for recovery of true time-lapse (TL) signal, where multiple data sets are involved, differs substantially from the usual approach. A TL study involves surveys acquired over a period of time. Careful preplanning is seldom undertaken in the design of the original surveys, resulting in data sets that resulted from different acquisition designs and technology. The acquisition geometry, signal, and noise contents and the resolution limits of the data sets can be very different. Unlike the single survey case, extraction of the true TL signal demands application of processes that restore common signal characteristics and identical S/N and resolution for the datasets.
