Diagenesis
Know More

Diagenesis plays a considerable role in controlling the quality of a reservoir within a trap As discussed in Chapter 6 solution can enhance reservoir quality by generating secondary porosity whereas cementation can destroy itIn some situations diagenesis can actually generate a hydrocarbon trap Rittenhouse 1972 Oil or gas moving up a permeable carrier bed may reach a cemented zone...
