Method for obtaining an image of a subsurface by regularizing irregularly sampled seismic data |
摘要 |
There is provided a method of spatially shifting seismic signals acquired through a seismic survey using the steps of identifying within the signals a set of N actual locations of seismic receivers and corresponding N seismic signals received by the set of seismic receivers; identifying a set of N′ desired locations of seismic receivers; and determining a set of N′ signal values at said N′ desired locations by evaluating for each of said N′ signal values a weighted sum of the N seismic signals, wherein the weights are at least partly determined by the relative distance between pairs of locations selected from said set of N actual locations of seismic receivers. |
