1. A method of fracture conductivity tuning comprising:
positioning elements in a geological system for adjustable hydraulic conductivity based on surrounding temperature of fractures within a subsurface of the geological system to provide a uniform or substantially uniform heat extraction via working fluid passing through the fractures;
wherein the elements comprise thermally sensitive proppants and/or adjustable clogging material (ACM), wherein the thermally sensitive proppants comprise calcium carbonate, one or more shape memory polymers, and/or at least one metal, and wherein the ACM comprises one or more inorganic salts, one or more polymers and/or one or more organic salts; and
wherein the elements are placed in the fractures and at least one injection well in fluid communication with the fractures.
