Methodology and Techniques - Trace Fossils as Indicators of Sedimentary Environments - page 256

FIGURE 10 Characterization of the impact of bioturbation on reservoir quality, connectivity, and
flow behavior by performing scenario modeling in SBED (Geomodeling). Various kinds of trace
fossils (burrows) are given a specific morphology, size, and variability before they are arranged as
an ichnofabric with different tiers, amount of bioturbation, colonization surfaces, and cross-cut
relationships. Based on process modeling, the heterolithic tidal-flat lithofacies are simulated in the
form of a digital well core and combined with the ichnofabric. Each trace-fossil group has assigned
porosity and permeability values. Numerous realizations, property modeling, and different upscaling
methods allow for comparison of non-bioturbated with bioturbated rock and to identify sensitivities
in bioturbation-related rock properties.
