Abstract

Well X Field Z is classified as heavy oil and there are several things that cause a decrease in production flow rate, one of which is due to a decrease in reservoir pressure. The decrease in pressure in the reservoir affects the ability of fluid to flow over the surface, causing the production rate to be less than optimal. Accuracy in selecting tubing size also influences determining the optimum flow rate of a well. Nodal Analysis is an alternative method for determining tubing size and determining optimum flow rate, namely by connecting the Inflow Performance Relationship (IPR) curve with Vertical Lift Performance (VLP), so that you can determine the optimal flow rate in a production well. Comparative analysis of tubing sizes with varying diameters of 2.5 inch, 2.785 inch, 3 inch, 3.5 inch, 4 inch, and 4.5 inch using Prosper software was carried out in this research to determine the tubing size that produces optimal flow rates using the IPR method, namely Vogel and Fetkovich. The research results show that the tubing size that produces the optimal flow rate using Vogel IPR is 4 inch tubing size with an optimal flow rate of 1807.85 STB/day and for Fetkovich IPR it is 4 inch tubing size with an optimal flow rate of 2026.02 STB/day.
