Abstract: A relatively large number of calcite-cemented fractures are present in gas-bearing shale formations. During hydraulic fracturing, some of these fractures will be reactivated and may become important flow paths in the resulting stimulated fracture network.… read more here.

Abstract: Abstract. The most spectacular wormholes are caves in fractured limestone terrains. Here, a model of their evolution is presented. The modeling domain is a two-dimensional square net consisting of one-dimensional fractures with given width b… read more here.
