摘要： A method of increasing the permeability of a geological structure is described. The method comprises applying multiple fluid-conductivity increasing processes to a geological structure at different diffusion length scales based on geological properties of the geological structure. At least one of the processes is arranged to operate on the geological structure at a grain level diffusion length scale, and at least one further process is arranged to operate on the geological structure at a macroscopic diffusion length scale. The processes are applied to increase the permeability of the geological structure by creating fractures in the geological structure and/or increasing the size of existing fractures in the geological structure. The method further comprises applying at least one of the selected fluid conductivity increasing processes cyclically, and the fluid conductivity increasing processes are substantially applied at a level below a failure level expected to cause macroscopic failure of the geological structure.
