Abstract
The Inflow Performance Relationship (IPR) curve is one of the main tools that production and reservoir engineers use to represent the reservoir delivery capacity at different flow rates for each pressure differential between the reservoir and the well. In this context, the IPR curve is necessary for the well design completion, production optimization, nodal analysis calculations, and artificial lift design. In this sense, this work aims to present two case studies using the simulator PETRO-IPR to predict the IPR and Productivity Index (PI) curves. The PETRO-IPR’s algorithms were built from the Vogel and Mass Quadratic models to calculate the IPR and PI curves for undersaturated and saturated reservoirs, and field data were used to validate these algorithms in previous works. In this paper, the simulator was used to predict IPR curves for PI in transient flow and analyze the influence of the skin effect on the IPR curve. The results showed a decrease in the flows over time when considering the PI in transient flow. Regarding skin factor effects on the IPR curve, it was possible to check damage and stimulation depending on the skin values adopted.
