Diagenetic effect barite
WebJan 19, 2024 · Dissolution is the diagenetic process by which carbonate and evaporite minerals are dissolved and removed, thus creating and modifying pore space in reservoir rocks (see Reservoir quality). The effect of this process on permeability depends upon the geometry and location of the resulting voids relative to the rock fabric. Web英语使用场景.
