Method for restoring seismic data to missing or severely noise contaminated traces included in a seismic section. The seismic section is transformed into a data localizing space and muted to retain only the localized data components of the seismic section. The muted transform space is inverse-transformed into the x-t domain to produce first estimates of the seismic data to be restored. The first estimates of the restored data are substituted for the corresponding traces in the original seismic section. Fully restored traces corresponding to the missing or severly noise contaminated traces are determined from the single estimate of the restored traces.

A method of restoring seismic data to a null trace included as part of a series of seismic traces comprising steps of: a single non-iterative procedure for a transform which band limits acquired data, by producing a data localizing transform representation of said series of seismic traces; applying a mute capable of passing only the localized data portion of said localized data transform space corresponding to said transformed series of seismic traces; producing a second series of seismic traces from said muted transform, said second series of seismic traces including a partial restoration of said null trace; substituting said partially restored trace for said null trace in said first series of seismic traces; and producing a seismic section which includes a full restoration of said null trace from said substituted series of seismic traces.
