An improved inflow performance model that provides the performance of oil wells having any slant angle within the entire azimuth of 0-90 degrees, in saturated and under saturated reservoirs. A generalized model is formulated by normalizing the coefficients of inflow performance relationship (IPR) model by performing a linear regression analysis. The generalized model is further modified to account for skin factor and is also integrated with a straight line IPR to be suitable for determining the performance of under saturated oil wells. For the case of flowing bottom-hole pressures above bubble point pressure, the straight line IPR model is used to determine the flow rate of the oil well, whereas for the case of having bottom-hole pressure below the bubble point pressure, the generalized IPR model is used to determine the flow rate performance of the well.
