Importantly, we can model the effects of faulting not just simply within fault cores, but also within the damage zones around them. Using throw and juxtaposed stratigraphy, we can derive fault-rock type and damage zone structure, and model their consequent effects on fault plane permeability and transmissibility. Fault throw plot produced by ABAL's new FaultRes software.
Reds indicate areas of highest throw, and dark blues low throw.
Fault seal potential plot produced using FaultRes. The yellow and green areas indicate poor fault seal potential. The integration of reservoir data at all scales is the key to evaluating and quantifying small scale structure. We use core, image log and petrophysical data, and conventional and seismic attribute data, to define parameters for the stochastic modelling of subseismic structural features, using scale invariant models. Along with major faults, these small scale structures have a demonstrably significant effect on the flow characteristics of the reservoir interval over the entire area of the field.
