... Carbonate reservoirs with varied depositional environments and diagenetic processes have assorted mineral composition and diverse pore structures, making it difficult to investigate the correlation between pressure and elastic velocity. The pressure-velocity relationship is influenced...

... for these purposes. The approach used in this article explores the analogy between the Ohm and Darcy Laws, considering that electric current flows along the same paths as the reservoir fluids. The fractured carbonate reservoir was, then, simulated as an electrical circuit, placing the resistances in series...
