Abstract: The gradual shift of attention from the conventional well completion to smart well completion has triggered the call for information concerning smart wells operations and methods for evaluating the performance of smart wells. In this paper, an integrated model was reviewed and used to calculate the dimensionless oil flow rate and bottomhole flowing pressures variables. Oil production data from a commingled smart well were simulated on a FASTWELL software and their plotted IPR results analysed to study; the oil inflow rate for a single phase flow, oil inflow rate for a multiple phase flow, Absolute Open flow (AOF), the effect of water and gas on oil inflow rate and the effect of anticipated formation damage. The results obtained show that the actual oil inflow rate is 4,800 bbl/d for 8USIG while the other two commingled reservoirs follow the same trend. The actual oil absolute open flows (AOF) are 4,575.1 bbl/d, 7,670.4 bbl/d and 6,528.6 bbl/d for 7USIG, 8USIG and 9USIG respectively. Comparing these AOF values to the total AOF mostly used for decision in well performance, it is evidence that the total AOF contributes errors to well performance decisions as investigated. The oil inflow rate for smart well is 20,500 bbl/d, while the total inflow rate of producing zones under conventional completion assumption gives 19,000 bbl/d. The three producing reservoirs show a significant increase in the AOF for oil in the absence of gas and water in the oil inflow stream. The approach used here provides a quick insight for early isolation of the errors contributed by gas and water in the analysis of oil inflow performance relationship (IPR) curves.
