Advanced Time and Depth Processing for Onshore Seismic

  • A comprehensive suite of land processing tools are available at TGS, from the input of field data to the final imaged results. Modern, interactive geometry resolution modules are fast and accurate.

    Prestack interpolation workflows are essential for minimizing prestack migration artifacts, azimuthal data regularization prior to fracture detection inversion, reconciling sampling differences in merge processing, and footprint removal in CMP stacking. 5D interpolation, as well as coherence-guided data reconstruction techniques are available.

    Noise Attenuation tools are important to address the diverse noise types present in land data. Some specialized products include the Intelligent Coherent Noise - ICone™ and Signal TO Noise Enhancement - STONE™.

    Interbed multiples present a significant challenge in land processing. They can be addressed using high resolution radon techniques, with available parabolic and linear options.

    Combining multiple 3D datasets into a cohesive output volume can pose challenges. An interactive Merge tool enables a quick and accurate method to match phase and statics, as well as QC the result.

    TGS has the ability to run 2D and 3D Kirchhoff prestack time migration (PSTM) with output either to gathers or stack. An efficient, interactive velocity module (PVEL) is also employed.

    Preservation of relative amplitude information is critical for many downstream applications such as AVO, LMR, and azimuthal AVO.
