Abstract

The characteristic features of compaction bands in high-porosity sedimentary rocks were investigated using numerical simulations. A discrete model was developed for investigating formation mechanisms of compaction bands, in which material was represented as a hexagonal lattice of springs which can transfer only normal forces. Parametric analysis was also conducted to explore and predict conditions under which compaction bands form and develop. The results show that for a non-homogeneous material, the stress drops, originating due to large disorder, will be small and quite frequent.
