Enhanced oil recovery is the actual effort implemented by the government to improve oil production in Indonesia in order to fulfill 1 million barrel target per 2030. One of the utilized methods is fluid-based chemical injection with surfactant as main material. One of the most common surfactants is petroleum Sulfonate, synthesized from petroleum. Petroleum Sulfonate is categorized as anionic surfactant. Lignin is the main material for lignosulfonate, which is a different type of anionic surfactant that can be utilized as injection fluid on oil reservoir. Lignin can be found in almost all types of plants. One of the plants that contain the highest lignin is bagasse. Lignin can be synthesized into lignosulfonate through two processes, namely the isolation of lignin and followed by the sulfonation process of the lignin. The synthesis of bagasse lignin produces a lignosulfonate surfactant which has a suitable Hydrophilic-Lipophilic Balance value to form an oil-in-water emulsion. Lignosulfonate bagasse can reduce the value of interfacial tension which will make the free oil droplets easier to move and produce. This effort could provide the assistance needed to reach the one million barrel per day target by 2030. From the results of this study obtained lignosulfonate bagasse that meets the requirements and is compatible with the crude oil sample used. Sugarcane bagasse synthesized into sodium lignosulfonate is a sophisticated material that could benefit an enhanced oil recovery process.
