We discuss a TSVD (truncated singular value decomposition) optimization scheme for history matching. We are particularly interested in studying the performance of TSVD under integration of P-wave velocity data. We compare the structure of the main singular value triplets with or without time-lapse seismics. We then analyze the impact of introducing the seismics in a synthetic two-phase model problem. We observe in our experiments a strong regularization of the inversion algorithm due to the seismics. At the same time, we obtain much better reservoir descriptions when 4D seismics is available.
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.
