Abstract
Formation water contains ionic compounds that can have an impact on the environment and living things, the process of formation water treatment aims to reduce the levels of ionic compounds contained in formation water so that it can be used for injection into the reservoir or discharged into the environment so as not to damage the equipment in the well. injection and does not have a negative impact on the environment and living things. In this study, the formation water used has a Ph value of 7.75, a turbidity value of 60 NTU, a DHL value of 30.4 dS/m, an oil and grease value of 38.27 mg/L, a Mg value of 27.3 mg/L, a Ca value of 56 ,7 mg/L, Fe value 0.274 mg/L and SO4 value 0.85 mg/L. One thing that can be done to reduce ionic compounds in formation water is to treat it using graphene oxide from palm oil shells, because GO shows a significant and efficient potential for filtering ions in water. The method used is the method of immersion and slow filter. Two methods were used in order to compare the most effective methods in the formation water treatment process. The manufacture of graphene oxide material using a thermal method, namely pyrolysis, then activated with 60% HNO3, then sonication and centrifugation processes, then synthesis of graphene oxide with FTIR and UV-Vis characterization. FTIR characterization shows the presence of C-O, O-H, C=C, and C=O bonds which are the main characteristics of graphene oxide. UV-Vis characterization showed a peak at 211 nm, this proves that the material is graphene oxide. The treatment process is carried out with different percentages of graphene oxide and water volume, namely 20%, 10%, 6.7%, 5% and 4% for both the immersion method and the slow filter method. The results of the pH and turbidity test on all samples showed that the sample with a percentage of 6.7% was the best/optimal with a pH value of 8.87 and a turbidity of 3.67 NTU for the immersion method and a pH of 8.88 and a turbidity of 4.27 NTU for the immersion method. slow filter. Then the two recommended samples were tested for some ionic content. For the immersion method, the DHL value is 17.68 dS/m, the oil and grease value is 9.68 mg/L, the Mg value is 13.14 mg/L, the Ca value is 10.41 mg/L, the Fe value is 0.26 mg/L. and the value of SO4 3.20 mg/L. For the slow filter method, the DHL value is 27.90 dS/m, the oil and grease value is 12.35 mg/L, the Mg value is 16.90 mg/L, the Ca value is 11.81 mg/L, the Fe value is 0.27 mg/L. L and SO4 value 2.68 mg/L. The results show that the immersion method is considered more effective than the slow filter method based on data from the results of testing the content of ionic compounds.
