DM FWI: From Statics to Dynamics

Dynamic Matching FWI (DM FWI) can resolve a higher level of details in shallow velocity models compared to traditional approaches such as reflection/refraction tomography. The advantages of a detailed model are evidenced by capturing shorter wavelength corrections, minimizing the need for residual statics.

Compressive Sensing Reconstruction

Compressive sensing (CS) aims to reconstruct high-quality seismic data from sparsely sampled datasets, often acquired with fewer sources and receivers than traditional methods. This approach is particularly valuable for reducing costs and improving efficiency of onshore seismic surveys.

Inversion-based Deblending

Most modern seismic onshore surveys are acquired with some level of source blending be it in the form of self blending or from additional sources. Inversion deblending is necessary as typical denoise deblending methods will not be able to sufficiently separate the events into their appropriate shots, potentially causing significant signal reduction or leaving in a large amount of blended energy, reducing the signal-to-noise ratio in the data.

Demultiple Toolkit

The nature of onshore complex geological settings requires a 3D demultiple solution, particularly as spatial effects magnify the complexity of the generated multiples. TGS offers a comprehensive 3D demultiple package that utilizes full azimuth contribution in its prediction and can attack multiples effectively in streamer, OBN, OBC and land surveys.
