Analisis Penentuan Laju Alir Maksimum Dan Optimum Berdasarkan Grafik IPR Pada Sumur X Lapangan Y Dengan Menggunakan Metode IPR Vogel

In the initial stage of production, a natural flow is carried out using a large enough reservoir pressure that pushes the fluid to the surface. Over time the reservoir pressure decreases in production due to pressure drops, large water production rates, and other well problems. So that the nodal analysis is carried out, nodal analysis is a method or technique in determining the relationship between the inflow performance relationship with the intake tubing which can determine the optimum production flow rate relationship. This study aims to determine the maximum amount of flow rate based on the IPR graph and determine the optimum flow rate based on the difference in GOR prices. By knowing the optimum flow rate so that production can be adjusted as best as possible so that the production process can last a long time until the use of artificial lift methods and other secondary methods. In this analysis the pwf value obtained is 1101 psi and for the maximum flow rate value of 1642,897 bopd can be seen in the IPR 4.1 graph. For the optimum amount of flow rate obtained with a pressure traverse graph of 100 psi with a GOR value of 500 scf / bbl by plotting the IPR graph, namely 1350 bopd
