A large-scale Gulf of Mexico OBC simultaneous source case study: Shot separation

Le résumé fourni par la source

Simultaneous-source acquisition achieves significant gains in acquisition efficiency by allowing the energy from multiple shots or sources to interfere such that multiple vessels can be acquiring simultaneously and continuously, reducing the overall acquisition time. This interference must then be addressed when processing the data. One strategy is to carefully plan the vessel acquisition so that the energy from one source instance can be separated from the continuous stream. This case study describes the separation of continuously recorded, multicomponent data into discrete shot records, as would have been recorded conventionally. The dataset in question is both large and complex, posing many challenges for separation in a production setting. We demonstrate that the combination of carefully designed acquisition rules and sophisticated processing yields separated data of high quality. We describe the enabling technologies related to data quality, robustness and efficiency, as well as showing some of the products used for QC purposes.
