Abstract

The Enhanced Oil Recovery methods used to increase oil production from a reservoir. The purpose of this study is to determine the type of Enhanced Oil Recovery method that is most appropriate for use in an oil field with certain conditions. Enhanced Oil Recovery is a tertiary recovery process carried out by injecting fluid through injection wells and producing oil through production wells. Before choosing the method to be used, first perform screening criteria. EOR screening needs to be done because this field still has large original oil in place, but production is very low. Screening criteria is done by matching the field data with the data of the parameters specified in the method to be used. There are nine parameters that are used as a reference for screening. One of the samples of the oil field that was analyzed with screening criteria was the Jatibarang Field. Based on the existing parameters in the Jatibarang field, there is a 55-60% similarity between the field data and the screening criteria parameters for CO2 flooding, namely permeability, porosity, density, SG, viscosity, oil saturation and reservoir temperature. So based on the discussion that has been carried out on the results of this study, it can be concluded that the oil field in Jatibarang is suitable for using the CO2 flooding method for the enhanced oil recovery process.
