Abstract: Methods, software, and computer systems for 3D multiple prediction and removal are disclosed. The method includes determining a set of input diplets. The method includes, for one or more data diplets from the set of input diplets downward propagating the data diplet to model reflection of the data diplet at a location of at least one subsurface discontinuity and determining one or more predicted multiple diplets, based, at least in part on the data diplet and the modeled downward propagated and reflected diplet. The method includes comparing diplets in the set of input diplets with the one or more multiple diplets to determine a set of multiple diplets and a set of demultipled diplets.

Abstract: Methods, systems, and software for determining a seismic image of a target area are disclosed. The target area is defined by a volume of interest (VOI). The method includes receiving an unmigrated set of spatial wavelets, wherein the unmigrated set of spatial wavelets include unmigrated spatial wavelets in the time domain. The method includes receiving a first migrated set of spatial wavelets, wherein the first migrated set of spatial wavelets includes migrated spatial wavelets in the depth domain. Each spatial wavelet comprises information about spatial location, orientation, amplitude, wavelet, acquisition configuration, and coherency. Each spatial wavelet in the unmigrated set of spatial wavelets is linked to a spatial wavelet in the first migrated set of spatial wavelets. The method includes selecting spatial wavelets from the first migrated set of spatial wavelets that are within or slightly outside the VOI; selecting a target set of spatial wavelets, the target set of spatial wavelets including spatial wavelets from the unmigrated set of spatial wavelets that are linked to the selected spatial wavelets from the first migrated set of spatial wavelets; migrating the target set of spatial wavelets using one or more of a new velocity model to create a second migrated set of spatial wavelets; and synthesizing the second migrated set of spatial wavelets into a new seismic volume and synthesizing the second migrated set of spatial wavelets into one or more new seismic gathers.
