Determination of Polymer Injection Method to an Oil Field Using Screening Criteria: Literature Review

Abstract

The amount of oil reserves in Indonesia is currently still large, but has not been able to meet the needs of enegi. To overcome this imbalance, one of the efforts that the government has made in improving oil lifting is through Enhanced Oil Recovery (EOR). The purpose of this research, is to determine the right EOR method for a reservoir by conducting a screening criteria on one of the fields in Indonesia. EOR is a method of increasing the volume of oil that previously could not be produced. This condition usually occurs in heavy crude oil, poor permeability and irregular faultlines. EOR is applied to fields that have been produced long enough (mature field) with the aim of taking the remaining oil that cannot be produced by primary and secondary (water flooding) methods. Some of the EOR techniques that are widely known to date are steam flooding, chemical flooding, and gas injection (gas flooding). The study is a reservoir X that has a six-aspect match from seven aspects suggested by Taber et al. namely polymer injection as an EOR method. The six aspects are the magnitude of oil gravity, oil viscosity, porosity, permeability, depth and temperature. From this research it can be concluded that, in Field X is very suitable for the EOR Method with the Chemical Flooding Method, by injecting polymer compounds.
