Method for seismic trace interpolation using a forward and backward application of wave equation datuming
This patent describes, in seismic exploration wherein seismic sources are activated at spaced locations along a surface of exploration and the amplitude of reflections are recorded as a function of time along the surface to produce a first series of seismic traces, the series of seismic traces including at least one null trace, a method of interpolating seismic data for the at least one null trace. It comprises: relating the first series of seismic traces to a first datum plane; propagating the series of seismic traces related to the first datum plane to a fictitious second datum plane using forward wave equation datuming to create a second series of seismic traces; propagating the second series of seismic traces back to the first datum plane using backward wave equation datuming to interpolate seismic data for the at least one null trace; and producing a seismic section for the surface of exploration from the series of seismic traces and the produced seismic data.
