Facies Constrained Elastic Full Waveform Inversion

Current efforts to utilize full waveform inversion (FWI) as a tool beyond acoustic imaging applications, for example for reservoir analysis, face inherent limitations on resolution and also on the potential trade-off between elastic model parameters. Adding rock physics constrain... Read More.

Accuracy of Wavelets, Seismic Inversion and Thin Bed Resolution

Broadband re-processed seismic data from the NW Shelf of Australia were inverted using a standard approach to wavelet estimation. The inversion method applied was a facies-based deterministic inversion where the low frequency model is a product of the inversion process itself, co... Read More.

Facies-based inversion through the asset lifecycle

Seismic lacks low frequencies, so for an absolute seismic inversion (which allows us to be quantitative) a so-called Low Frequency Model (LFM) is required.  Starting from an empty LFM, we would of course like to post Sand Vp values where there is Sand, Shale Vp values whe... Read More.

Seismic and Rock Properties

Full-field unconventional reservoir characterization employs elastic properties from seismic to image pay zones, calculate stresses and understand rock strengths in order to optimize development plans. The link between seismic data and the subsurface properties of interest often ... Read More.
