Abstract

Estimates of wall-rock strains provide an objective means for discriminating between correct and incorrect structural interpretations of 2D and 3D seismic data. Good interpretation of faults should include a workflow that checks and keeps wall-rock strain below a geologically plausible maximum. We call this the strain minimisation approach.
