Quantitative interpretation requires true amplitudes and high signal-to-noise ratio.
DUG MP-FWI Imaging delivers superior pre-stack reflectivity outputs for both AVA analysis, and, elastic rock property and fluid prediction—directly from field data.
In the figures below, two equivalent crossplots of elastic rock properties (from simultaneous AVA inversion of pre-stack reflectivity) are shown. On the left, the inputs are from a conventional workflow. On the right, from DUG MP-FWI Imaging. The ellipses indicate the expected distribution of the labelled lithology and fluid combinations from well-log analysis. The MP-FWI results exhibit less scatter, or higher signal-to-noise ratio, which translates to less uncertainty.
By eliminating the need for a conventional pre-processing workflow (and its assumptions/workarounds that ultimately affect the AVA compliance of the data) more certain predictions can be realised.
“Results from a shallow water environment indicate that MP-FWI from raw shots provides useful information for AVA analysis not readily available through conventional processing.”
