Vertical seismic profiling
A method is described for converting vertical seismic profiling (VSP) seismic data to surface seismic data. The seismic source used to obtain the VSP seismic data was offset a desired distance from a borehole, the method comprising the steps of: (a) selecting a first VSP data trace from the VSP seismic data; (b) mapping segments of the first VSP data trace at respective VSP times into locations on a plot of surface seismic time as a function of distance from the borehole; (c) repeating steps (a) and (b) for at least a portion of the VSP data traces, other than the first VSP data trace, in the VSP seismic data; and (d) summing sections of each VSP data trace which are mapped into the same location in the plot to produce the surface seismic data.
