Abstract

The chemical EOR method that is widely applied in the oil and gas industry is polymer injection because it is easier to apply and cheaper, and has been applied since the early 1960s. This injection involves adding a thickening agent to formation water to increase its viscosity with the aim of increasing sweep. efficiency by reducing the water-oil mobility ratio so as to increase the viscosity. Currently, the polymers used in the chemical EOR method are divided into two classes, namely synthetic polymers and biopolymers. Types of complex biopolymers such as starch, dextran, xanthan, chitosan and cellulose. One of the plants that can be used in the manufacture of biopolymers is banana stems. Banana stem has a cellulose polysaccharide content of 83.3%, banana stem is used as a material for making biopolymers which will later be applied to the application of the chemical EOR method. The stages in this research were sample preparation, extraction, bleaching, synthesis and characteristic tests in the form of compatibility, density, viscosity, and Fourier Transform Infra-red (FTIR) tests. This study used variations in salinity concentrations of 10,000 ppm, 20,000 ppm and 30,000 ppm and at temperatures of 70°C and 80°C
