This blog focuses upon stylolites which are structures that either form during burial or by later tectonic movements and have a serrated appearance on rock surfaces.
Relay ramps can create communication between fault blocks during an oil field development. Here we look at some examples and other types of segmentation which occur in weaker rocks.
Fracture swarms are concentrated zones of open fractures, over which there is little or no offset. Although there are excellent outcrop examples, these structures can be difficult to identify in the subsurface. An integrated static-dynamic approach is best to successfully identify fracture swarms.
