Compaction 02
Compaction 02 : A crushing of the matrix structure as overburden loads press down on the rock, reducing the pore space. During production of the well, the load on the matrix increases as the pore-filling fluids are removed. These loads may reduce the porosity of the rock expelling fluids from the rocks (compaction recovery of fluids). Permeability may be decreased in compaction, first by closing natural (unpropped fractures) and then by reduction of matrix perm in severe cases
