Seismic inversion of a carbonate buildup: A case study

The information within seismic data is band limited and angle limited. Together with the particular physics and geology of carbonate rocks, this imposes limitations on how accurately we can predict the presence of hydrocarbons in carbonates, map the top carbonate, and characteriz... Read More.

The present-day stress field of Australia

The unusual present-day crustal stress pattern of the Australian continent has been the subject of scientific debate for over 25 years. The orientation of maximum horizontal present-day stress (SHmax) in continental Australia is unlike all other major tectonic plates in that the ... Read More.

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.
