Title:
METHOD AND SYSTEM FOR DETERMINING MIGRATION DATA USING CROSS-SPREAD GATHERS AND PARALLEL PROCESSING
Document Type and Number:
WIPO Patent Application WO/2024/087126
Kind Code:
A1
Abstract:
A method for determining migration data using cross-spread gathers and parallel processing. The method may include obtaining various cross-spread gathers regarding a geological region of interest. The method may further include determining traveltime table data based on the cross-spread gathers(420). The method may further include transmitting the cross-spread gathers to various parallel processing groups in a parallel processing network(430). A respective cross-spread gather among the cross-spread gathers may be transmitted to a respective parallel processing group among the parallel processing groups. The method may further include determining, by various parallel processing nodes in the respective parallel processing group, a first subset of a migrated dataset using the respective cross-spread gather, a subset of the traveltime table data, a velocity model, and a migration function(440). The method may further include generating, based on various subsets of the migrated dataset that includes the first subset, a first seismic image of the geological region of interest(460). It also includes a system for determining migration data using cross-spread gathers and parallel processing.
