Uji tegangan antar muka (Interfacial tension, IFT) antara minyak dan mikroemulsi merupakan salah satu parameter utama dalam proses EOR. Pengukuran tegangan antar muka perlu dilakukan sebelum surfaktan digunakan sebagai fluida injeksi. Alat yang digunakan untuk mengukur tegangan antar muka adalah Spinning Drop yang dapat mengukur tegangan antar muka hingga 10-6 mN/m. Perhitungan IFT pada alat ini menggunakan persamaan Vonnegut. Hasil pengukuran IFT ini kemudian diplot dalam satu grafik untuk mendapatkan persamaan garis yang terbentuk dengan melihat koefisien korelasi (R) dari persamaan garis pada grafik tersebut. Berdasarkan persamaan garis yang terbentuk, koefisien korelasi yang diperoleh untuk salinitas 10.000 ppm dan 20.000 ppm adalah 0.9841 dan 0.9258 dapat digunakan sebagai sample karena dapat mewakili populasi. Nilai koefisien korelasi 0.9841 dan 0.9258 keduanya diatas 0.9, maka dapat diartikan bahwa korelasi antara X dan Y sangat kuat sekali. Kondisi ini menunjukkan bahwa pasa sistem surfaktan NaLs ampas tebu dengan sampel minyak ringan dapat terjadi korelasi yang sangat kuat antara konsentrasi surfaktan NaLS terhadap nilai IFT pada sistem surfaktan NaLS – minyak. Karena nilai koefisien korelasi diatas 0.9 maka dapat digunakan sebagai sample karena dapat mewakili populasi dan rumus persamaan korelasi dapat digunakan untuk menghitung nilai IFT berdasarkan konsentrasi surfaktan yang digunakan. Penentuan nilai IFT pada salinitas larutan 10.000 ppm, dapat dihitung berdasarkan konsentrasi yang digunakan dengan menggunakan rumus Y = 5103,7 X2 - 294,96X + 5,9561. Sedangkan pada salinitas larutan 20.000 ppm, nilai IFT dapat dihitung dengan menggunakan rumus Y = 2666,1 X2 - 249,07X +7,8571

Surfactant flooding may increase oil recovery by lowering interfacial tension between oil and water. Bagasse is one of the organic materials which contain fairly high lignin, where lignin is the basic substance of making Natrium Lignosulfonate (NaLS) Surfactant. In this research, bagasse based surfactant was applied for surfactant flooding. The research was divided into two sections, namely: phase behavior test and NaLS Surfactant flooding where the water contained 70,000 ppm NaCl. Two surfactant concentrations which were used were 0.75% and 1.5% NaLS surfactant. Phase behavior tests were carried out to find the middle phase emulsion formation. Based on phase behavior test results, the percentage of emulsion volume for 0.75% and 1.5% NaLS is 13.75% and 8.75%, respectively. NaLS surfactant flooding was performed for to obtain the best recovery factor. FTIR equipment used determine recovery factor. The optimum condition was obtained at 0.75% NaLS surfactant concentration where the recovery factor was 4.4%.

The majority of petroleum production comes from the brown field where production has decreased from year to year in Indonesia. To increase the recovery factor of petroleum from the reservoir, an advanced step of production is required, Enhanced Oil Recovery (EOR), which can optimize the depletion of old oil fields. EOR is the application of technology that requires cost, technology and high risk. Therefore, before implementing EOR, in a field, we must carefully evaluate both technically and economically to obtain an optimal additional recovery. This research was conducted to increase oil production by injection of Methyl Ester Sulfonate (MES). This study begins with a screening parameter crude oil, formation water, Berea’s core, and determination of phase behavior, interfacial tension (IFT), thermal stability, imbibition, and core flooding tests. The result for concentratin optimum in 0.3% MES and had IFT 0.3267 dyne/cm. The results of core flooding tests are: Recovery factor of waterflooding is 33.95 % and recovery factor of MES injection is 4.19 %.

In spontaneous imbibition researches, surfactant has been employed to control interfacial tension (IFT) and wettability. In this paper, the evaluation of grain size effect on spontaneous imbibition of surfactant solution is presented. In this work, the synthetic porous media (sand packs) with uniform and non-uniform grain size from 30 mesh to 100 mesh were made. The porous media were initially saturated by oil. Then they were immersed in brine with salinity of 62 to 40,000 ppm for 24 hours. After that, the porous media were immersed in surfactant solution with concentration of 0.2% for another 24 hours. The total oil recovery during these treatments was measured. The experiment was separated into three parts in order to investigate the effect of uniform grains, non-uniform grains, and salinity in spontaneous imbibition. The results show that grain size and porosity were proportional to oil recovery. In the case of porous media with uniform grain size, the effect of grain size on recovery factor is stronger than that of porosity. Meanwhile the salinity has an the optimum condition for a maximum recovery factor. In this study, it happened at salinity of 20,000 ppm. Oil recovery factors observed in this study ranged from 66.7% to 91.1%.

One of the efforts that can be done to evaluate the performance of water injection in a field is by monitoring the injector wells. Observations can be made by looking at the flow rate and injection pressure at each injector well. The response given by each injection well will be able to represent the injection performance on a field scale. The EX structure is a structure that has been produced for more than 40 years. In addition, water injection has also been applied for approximately 16 years. There are four injection wells operating in this EX structure with an average injection flow rate of 3000-8000 bwipd per well. Evaluation of injection well performance is carried out by conducting a Hall Plot on each injection well from the start of the injection process to the last data obtained. Based on the evaluation results, it was found that there was plugging in the EA-IIS and EJ-IVS injection wells. Stimulation activity is needed in both wells to restore the well injection capability. Meanwhile, for the EA-IS and EB-IIL injection wells, there are no significant problems in those wells so they can still function properly as injection wells.

Enhanced Oil Recovery (EOR) is known to effectively improve oil recovery by producing the residual oil saturation in a reservoir. Many chemicals for injected fluid in EOR are synthetic and harmful to the environment. Aims: This study aims to characterize a newly developed green solution consisting of Sodium Lignosulfonate (SLS) and a Low Transition Temperature Mixture (LTTM) for injection agent. Methodology and Results: The concentration of surfactant was defined using weight percentage, which was calculated from the portion of the total weight of LTTM. The characterization was approached by analyzing the behavior of the green solution based on the power law analysis of the rheological measurement. The analyses of value, viscosity, shear rate, and shear stress were carried out. Increasing in viscosity was caused by the additional molecular mass of sucrose in the solution. This study found that the SLS concentration and LTTM ratio affects the rheological behavior of the green solution. Conclusion, significance, and impact study: According to the results, adding the SLS concentration increases the probability of the green solution becoming an EOR agent by showing shear-thinning behavior. Further studies are required to ensure the feasibility of the green solution during the injection period and the propagation in the reservoir.

Eco enzyme is a product of organic waste derived from vegetables and fruits, fermented with sugar in a container and allowed to stand for three months to become an active solution. The use of eco-enzyme as a natural cleaning solution contributes to protecting the environment because it treats household-scale organic waste. The community service program aims to enhance Cigombong Village's potential with a community that cares about the environment that has been formed. The eco enzyme can be used to clean all areas of the house, clothes, vegetables, and fruits, fertilize plants, eliminate pests, and improve the quality of plants; the eco enzyme is also very effective in repelling plant pests. The eco enzyme can also be utilized to stimulate plant hormones to enhance fruit and vegetable quality and improve crop yields. Making eco enzymes can be done simply, using easily available equipment. The raw materials for eco enzyme consist of brown sugar, water, and fruit peel waste in a ratio of 1:10:3. The container used for the eco enzyme is a plastic jar with a lid. A training program for making eco enzymes from fruit and vegetable peel waste can protect the environment, increase community plantation yields and make Cigombong village a fruit tourism village.
