Cyclic confining pressure and rock permeability: Mechanical compaction or fines migration. [PDF]
Heliyon, 2023 The apparent rocks permeability, measured under cyclic loading, tends to constantly decrease with each subsequent loading/unloading cycle, the main reason for this, the researchers consider irreversible deformations. However, this understanding is not complete, as attention is not paid to the method of determining the permeability. Under cyclic loading,
