摘要： A system and method are disclosed for predicting, and optionally removing surface multiples from acquired seismic data that lacks surface consistency, such as seismic data acquired using an Ocean Bottom Cable (OBC) or Ocean Bottom Node (OBN) system where the sources are located at or near the water's surface and the receivers are located at or near the ocean's floor. By processing the acquired seismic data using seismic interferometry, source side and/or receiver side operators can be generated which satisfy the surface consistency requirement of techniques such as Surface Related Multiple Elimination (SRME) so that SRME or the like can be used to predict the surface multiples.

摘要： Apparatus, computer instructions and method for deghosting seismic data related to a subsurface of a body of water. The method includes inputting data recorded by detectors that are towed by a vessel, the data being associated with waves travelling from the subsurface to the detectors; applying a migration procedure to the data to determine a first image of the subsurface; applying a mirror migration procedure to the data to determine a second image of the subsurface; joint deconvoluting the first image and the second image for deghosting a reflectivity of the subsurface; and generating a final image of the subsurface based on the deghosted reflectivity of the joint deconvoluting step.

摘要： The present disclosure includes a method, which includes receiving a seismic data set including P-P data and P-S data, and preparing the P-P data and the P-S data for a joined inversion to produce prepared P-P data and prepared P-S data. The method further includes performing a joined inversion on both the prepared P-P data and the prepared P-S data to calculate final surface consistent scalars. The method further includes outputting a corrected P-P trace based, at least in part, on the P-P data, and a P-P gain, wherein the P-P gain is based, at least in part, on the final surface consistent scalars and outputting a corrected P-S trace based, at least in part, on the P-S data and a P-S gain, wherein the P-S gain is based, at least in part, on the final surface consistent scalars.

摘要： A method for using an offset vector tile gather to image a subsurface (1400) defines an offset vector tile gather by selecting a plurality of seismic traces from recorded seismic data (1404). Each seismic trace (123) in the offset vector tile includes reflections from subsurface reflectors and reflection points (124) at depths below the surface of the subsurface. Each reflection point is in a given seismic trace, and each given seismic trace extends from a seismic source (102) to a seismic receiver (104). The reflection points define an offset vector tile (612,712) having a source line span (120) and a receiver line span (118). The source line span is equal to or greater than a distance between adjacent seismic receiver lines (614), and the receiver line span is less than a distance between adjacent seismic source lines (714). The offset vector tile gather is used to produce a three dimensional image of the subsurface (1412).
