Recently, the increase in fuel oil demand was not supported by petroleum production due to the low productivity of old wells. Furthermore, an appropriate technology, such as Enhanced Oil Recovery (EOR) technology, is needed to maximize the productivity of the old well. Therefore, the purpose of this study was to synthesize a polymeric surfactant for the EOR process from sodium lignosulfonate (SLS) and polyethylene glycol (PEG) in various SLS to PEG ratios, namely 1:1 (PS1), 1:0.8 (PS2), and 1:0.5 (PS3). The surfactants were characterized using several methods, such as Fourier Transform-Infrared spectroscopy (FT-IR), compatibility, stability, viscosity, and phase behavior tests. The performance of the surfactants for the EOR process in different brine solution concentrations (16,000 ppm and 20,000 ppm) was also studied. The result showed that the introduction of the PEG molecule to the surfactant had been successfully conducted as FT-IR analysis confirmed. The surfactant's hydrophilicity increased with the introduction of PEG due to the increase of the ether group. A Winsor Type I or lower phase microemulsion was formed due to the high hydrophilicity. The highest oil yield (79 %) was obtained by PS1 surfactant, which has the highest PEG dosage, in a brine solution of 1,600 ppm. Therefore, it was concluded that the introduction of PEG could increase the hydrophilicity, viscosity, and EOR performance.

Adsorption Capability

This study is to investigate the adsorption capability onto kaolinite for different types of lignosulfonates in various salinity environment. Depletion method using the UV-Vis were used for measuring the concentration of lignosulfonate before and after the adsorption process in equilibrium and kinetic conditions. The highest amount of lignosulfonate adsorbed potrayed the best sacrificial agent that can be used in enhanced oil recovery application. The highest amount adsorbed of lignosulfonate onto kaolinite can prevent the surfactant lost into the formation. Among the four tested lignosulfonates, sodium lignosulfonate appeared the best in terms of adsorption capability in the presence of NaCl and CaCl2 salt in the system. Freundlich isotherm model was the best to describe the equilibrium adsorption data of sodium lignosulfonate. On the other hand, pseudo-second order model was the best to describe the kinetic adsorption data of sodium lignosulfonate.

Surfactants have been intensively used for Enhanced Oil Recovery (EOR). Nevertheless, environmental issues cause some surfactants to become unfavored in EOR application. Biodegradable surfactants are the suitable choice to make the environment safer. However, screening surfactants that have a good performance for EOR are time-consuming and costly. Molecular Dynamics (MD) simulation is an alternative solution to reduce cost and time. In the present study, oleic acid-based surfactants that combined with the various length of polyethylene glycol were studied. The potential surfactants were screened by MD simulation to evaluate their ability to reduce the Interfacial Tension (IFT) between oil and water layers, which is the by GROMACS software with Gromos force field and SPC water model. Carboxyl-terminal of the oleic acid was substituted by a different length of polyethylene glycol. All MD simulations were prepared in octadecanewater mixture with temperature ranges of 303-363 K. Our simulations found that the increasing number of polyethylene glycol was not always followed by the decreasing of IFT value between octadecane and water layers. These results were validated with the experimental data and found the similar IFT profile. The simulation of oil emulsification showed that all surfactant samples have good performance and stability as exhibited by their emulsification rate and emulsion stability in different temperatures. The last test to get the best surfactant was the wetability test. The simulation gave the result that both PEG100-oleic and PEG400-oleic were able to change wetability of rocks from oil-wet to water-wet. Accordingly, PEG400-oleic is the best nonionic surfactant candidate due to its performance in each simulation test.

Scientific Application

The purpose of this research is to get new product innovation process from bagasse, that is Sodium LignoSulfonate surfactant. Lignosulfonates surfactants in petroleum engineering are used as injection fluids into oil reservoirs to increase oil recovery, which is known as Enhanced Oil Recovery process. Lignosulfonates is made of lignin as raw material, which can be extracted from bagasse as one of its sources. Bagasse contains 24 - 25% lignin, so it is sufficient to be processed into lignosulfonates. Today, bagasse is one of the biomass resources widely used as a boiler fuel in sugar factory, source of animal feed, material for paper, cement and brick reinforcement .This study presents an innovation of bagasse utilization. This innovation involves two scientific application fields, firstly, chemistry in the processing of bagasse into sodium lignosulfonates surfactant and secondly, petroleum engineering in the effort of using sodium lignosulfonates surfactant to increase oil production from the reservoir. The last stage in this process is injection of the sodium lignosulfonates surfactant into a synthetic core in laboratory scale use water and surfactant injection.. The amount of oil that is produced from the injected core shows the increase in oil yield from the sodium lignosulfonates surfactant injection.
