In calculating the productivity of oil wells, it is commonly assumed that inflow into a well is directly proportional to the pressure differential between the reservoir and the wellbore. Many methods for calculating the productivity of vertical wells have been proposed in many literatures to calculate the inflow performance relationship under solution gas drive reservoir. Since horizontal and multi-lateral wells are likely to become the major means of modern exploitation strategies, the inflow performances for these wells are needed. For a vertical well, the majority of the pressure drawdown is occurred near the wellbore. Therefore, there is a big drawdown pressure around the wellbore in a vertical well. In the case of horizontal wells, the pressure drop is fairly uniform throughout the reservoir near along the horizontal wellbore. This pressure drop is, however, small as compared to that around a vertical wellbore. Because of inflow into a horizontal well is different from the inflow into a vertical well, the IPR equations which are developed for vertical wells should not be applied to horizontal wells without verification. In this work, a commercial simulator (CMG) is used to generate IPR’s of a horizontal and multi-lateral wells producing from a solution gas drive reservoir. The methods presented in this research are based on homogeneous reservoirs where the gravity and capillary effects are negligible. For every set of well, fluid and rock properties data, the inflow performance relationship curve is constructed and the dimensionless IPR curve is developed. The general dimensionless IPR curve is representing inflow performance of the horizontal and multi-lateral, however for application purposes the proposed dimensionless IPR curve should be validated.
