Compaction and Diagenesis

When sedimentary rocks are subjected to stresses, compaction occurs, resulting in a reduction in the volume of the rock. Land subsidence is a common cause of this occurrence. Both events are necessary for the production of sedimentary rocks and the creation of hydrocarbons. Compaction occurs when pressure and fluid production are reduced, resulting in a reduction in the volume of a reservoir. The majority of oil and gas reserves will only experience minor compaction, and the resulting sinking at the surface will be minimal.

The physical and chemical processes that impact sedimentary materials after deposition and before metamorphism, as well as between deposition and weathering, are referred to as diagenesis. Diagenetic processes have progressive influence on rock qualities such as porosity and lithification degree. It is important for maintaining the quality of a reservoir within a trap. As soon as sediment is deposited, diagenesis begins.
