Analisis Kinerja Waterflood Surveillance Pada Sumur Injeksi Y Dengan Metode Voidage Replacement Ratio Pada Reservoir Sandstone Dilapangan Z

Waterflooding is a method to increase oil production in the secondary extraction stage. Water injection is classified into 3 types, namely, Water Removal (used to inject formation water into unproductive layers), Pressure Maintenance (used to maintain reservoir pressure), and Waterflood (press injection water with a certain pattern to press oil from the reservoir to the oil). pressed into the production well). In the Marpoyan field. Waterflood performance analysis was carried out using the Voidage Replacement Ratio method. VRR (Voidage Replacement Ratio) is the ratio between the amount of produced water that is injected into the reservoir to the cumulative fluid that has been produced. This method is used to determine the reservoir pressure response due to injection, help determine production optimization strategies, and determine injection performance (withdrawal balance). This VRR analysis begins with grouping the area of injection wells and production monitoring wells based on observations of production performance data, injection performance, and reservoir pressure performance
