Abstract

Dewasa ini pro duksi minyak terus menunurun karena sulitnya menemukan sumur baru dengan skala besar dan usia sumur yang sudah tua. Oleh karena itu, di kembangkan enhanced oil recovery (EOR) untuk memaksimalkan produksi dari minyak. Penelitian ini bertujuan untuk mempelajari pengaruh kondisi operasi ( voltase, dan konsentrasi surfaktan) terhadap sifat partikel yang terbentuk selama sintesis dalam reaktor elektrokimia dengan konfigurasi multielektroda monopolar selang-seling dan mengevaluasi performa nanofluida yang tersusun atas nanopartikel magnetite bersalut silika yang terdispersi dalam air. Variabel yang digunakan pada penelitian ini adalah voltase dan konsentrasi PEG. Berdasarkan hasil eksperimen, didapat bahwa semakin tinggi voltase maka akan semakin besar ukuran partikel dan semakin rendah laju pengendapannya. Sedangkan pada variabel konsentasi PEG, semakin rendah konsentrasi PEG maka laju pengendapannya akan semakin rendah. Nanofluida yang memiliki laju pengendapan terendah pada penelitian ini terdapat pada kondisi 2 V dengan laju pengendapan 0.42 ml/menit. Berdasarkan uji kinerja, Nanofluida magnetite bersalut silika dapat meningkatan persen rekoveri sebesar 7.2 % sedangkan dengan menggunakan surfaktan saja persen rekoveri meningkat 2%.

Currently, oil production continues to decline due to the difficulty of finding new wells on a large scale. Therefore, Enhanced Oil Recovery (EOR) was developed to maximize oil production. This research aimed to study the effect of operating conditions on the properties of particles formed during synthesis in a chemical reactor with alternating monopolar multi-electrode configurations and evaluate the performance of nanofluids composed of silica-coated magnetite dispersed in water magnetite nanoparticles dispersed in the water. The variables used in this study were voltage and concentration of PEG. Based on experiments, it was found that the higher the voltage, the larger the size and the lower the speed. While the PEG concentration variable, the lower the PEG concentration, the lower the rate. The nanofluid, which had the lowest rate in this research, was at 2 V at a rate of 0.42 ml/min. Based on the performance test, the silica-coated magnetite nanofluid can increase the recovery percent by 7.2%, while using only surfactants, the recovery percentage increases by 2%.
