... failure if the high pore pressure depletion from production imparts excessive compaction strain on the completion assembly. We hypothesize that compaction-induced sand production failure is the result of a buckling mechanism where a large amount of stress and strain is exerted along the most slender...

In such circumstances, compaction banding results from the interaction between the rock heterogeneity and the temporal evolution of its mechanical properties. In this paper numerical analyses based on the Finite Element method are conducted to...

It is challenging to isolate features that are only related to early deformation in both outcrop and subsurface settings from those that occur from burial, uplift, and tectonism. To address this challenge, we...
