    "inventor_name": null,

    "device_name": "Electro-Osmotic Oil Recovery (EEOR)",
    "goal": "Increase oil production, especially heavy oil, by applying direct electric current to induce electro-osmotic flow, upgrade oil chemistry, and heat the formation, thereby reducing water use, energy consumption and environmental impact.",
    "problem_addressed": "High water and energy demand, environmental damage, and limited depth of steam-based heavy-oil extraction methods; unprofitable fracking.",
    "concept_summary": "Applying a DC electric field across an oil-bearing formation creates electro-osmotic flow that pulls oil toward the cathode, while electrochemical reactions (oxidation/reduction) break down heavy molecules and Joule heating reduces viscosity. The combined effects enhance permeability and oil mobility, allowing recovery from reservoirs where steam methods fail.",
