A method for enhancing mineral dissolution and permeability in subsurface rock formations, and a corresponding system, is provided. Electromagnetically responsive granular particles are introduced into fracture networks or fluid pathways within a subsurface formation. A surface-based generation apparatus applies an electromagnetic field that inductively couples with conductive fluids within the fractures or pathways, inducing localized electric currents at formation depth. Interaction between the induced electric currents and the granular particles modifies local electric field gradients and current distributions, thereby inducing electrochemical redox reactions at adjacent mineral surfaces and enhancing mineral dissolution and permeability. The invention is applicable to hydrocarbon reservoirs, geothermal systems, and mineral extraction applications, and is compatible with hydraulic fracturing, hydraulic shearing, and well completion workflows.
