Data replaced by 1D analytical model (D) Well in loading up. Data irreplaceable (H)

Data replaced by trained ANN (C) Fractured well with water. Data replaced by extrapolation (G) Eight different cases to replace real-time data. Pressure, gas, or oil rates and water cut are shown over a period of 7days. The replaced flows.
