Abstract:A target-oriented approach is developed to provide support for in-fill and re-shoot decisions during time-lapse (4D) marine seismic acquisitions. Repeatability quality of surveys positioning is determined from their respective illumination on selected reservoir horizons. Quality control of seismic repeatability is carried out from processing standpoint, through the check of 4D differences in target illumination fold and shifts in reflection-points. Corresponding support to re-shoot decisions is provided onboar… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
