Depth of Investigation for Multi-parameters Inversions

Proceedings, 2015
We have developed a new robust concept for the calculation of the depth of investigation (DOI) for inversion problems described by several intrinsic parameters, like the spectral inversion of time-domain induced polarization data or the inversion of full-decay Nuclear Magnetic Resonance soundings.

Depth-Domain Inversion for Enhanced Quantitative Interpretation

First EAGE Conference on Seismic Inversion, 2020
Summary Least-squares migration can help mitigate non-geological amplitude variations caused by uneven illumination. In this paper, we apply least-squares migration in the image domain to recover acoustic or elastic properties. Dipdependent illumination and wavelet stretch effects are captured using point spread functions (PSFs) and mitigated through ...

Full-waveform Seismic Inversion at Reservoir Depths

Proceedings, 2012
We apply 3D anisotropic acoustic full-waveform tomographic seismic inversion to a North Sea wide-angle OBC dataset, and demonstrate that our recovered velocity model is realistic within the chalk reservoir sequence to depths of up to 4000 m. Because we use predominantly wide-angle refracted arrivals in the inversion, we are able to undershoot and image

Full-waveform Inversion Aided Depth Imaging

Proceedings, 2012
Full-waveform inversion based on the finite difference approach was originally introduced in the time–space domain (e.g.Tarantola, 1984, Pica et al., 1990, Sun & McMechan, 1992). Inversion can also be implemented in the frequency-domain (Pratt et al., 1998, 1999, Ben-Hadj-ali et al., 2008).
