As karst features are buried into the deep subsurface and isolated from the mechanisms that formed them, they turn into paleokarst. Some karst features, such as hypogene and island karst, have a higher probability of being preserved into the deep subsurface, as opposed to epigene karst. As these features transition from modern karst to paleokarst, they are susceptible to collapse. When an individual passage or room collapses, it results in an increase in the void's areal and volumetric footprint. In addition, individual passages and rooms have the potential to collapse and coalesce into each other, further increasing the cave footprint. The end result is often a large zone of brecciated collapse. While the porosity has decreased, the collapse process integrates the permeability over a much larger area, which is the reason these collapsed paleokarst features form an important class of hydrocarbon reservoirs, paleokarst reservoirs.
