The geometries with less than 10% relative trace density (G3, G4, G5, and G6) show considerable levels of acquisition footprint on the amplitude...

... Ocean Bottom Node/Ocean Bottom Seismometer (OBN/OBS) data are currently sparse due to the acquisition costs in offshore oil-gas seismic exploration. Sparse spatially sampling of OBN/OBS highlights the problem of imaging acquisition footprints, poor phase continuity, and low signal-to-noise (S/N...

... ABSTRACT This abstract present a local morphological component analysis (MCA) based acquisition footprint suppression method, which is based on adapted dictionary sparse representation of time slices. Firstly, the time slice of seismic data is divided into many patches, and all these patches...

... ABSTRACT Acquisition footprint manifests itself on 3D seismic data as linear grid pattern of noise on time or horizon slices. Ideally, footprint suppression should be handled in the processing workshop. Unfortunately this is not an option for vintage poststack volumes where no pre-stack data...

... Summary Towed streamer seismic data suffer from acquisition footprint problem due to tides, water velocity, depth variation of streamers, etc. In order to improve the repeatability, we reconstructed repeatable 4D seismic data by choosing the only trace pairs (the sum of source and receiver...

.... Such processing errors may include improper statics, poor velocity analysis and not adequately removing coherent noise. The result of these errors, if not mistaken as geology, is often classified under the broad category of acquisition footprint. In this paper we use synthetic seismic data composed of four...

... Summary Whether it is in reference to the limitations of interpretation or associated with seismic processing, usage of the phrase acquisition footprint is never in a positive context. Footprint contaminates both time structure map and impedance inversion. Although common, footprint is often...

..., the target zone is contaminated with the acquisition footprint. The data are low (~15) fold and contaminated by highly aliased, high frequency, high amplitude ground roll. Given the sparsity of the survey, modern f-kx-ky filters were not able to remove ground roll prompting the development of a new ground...

Acquisition footprint is an undesirable artifact that masks the geologic features or amplitude variations seen on time slices from the seismic data, especially at shallow times. We begin our paper by correlating missing data and areas of low fold...
