Porosity and Permeability Analysis from Well Logs and Core in ...

Permeability and porosity of a rock are interrelated as higher porosity implies higher permeability. In addition, the grain size of a rock also determines the pore throat (narrow connections) that can exist in the reservoir rock thereby controlling the permeability rate. Coarse grained rocks such as carbonates and sandstones...

Cornstone | Geological Magazine | Cambridge Core

Two dissimilar rocks have been confused under the title “cornstone”: one is a concretionary limestone, the other a calcareous conglomerate. A return to the names “concretionary cornstone” and “conglomeratic cornstone” is advocated since the rocks differ in their significance. Conglomeratic cornstones, intra-formational in...
