Abstract

Nanoparticle with its nanoscale can be used as a data collector in every part of the development of the petroleum field. By having a hydrophilic condition for the nanoparticles, it can move to the targeted area in the water zone. The hydrophilic condition will differentiate between oil zone and water zone. The objective of the study is to use the hydrophilic nanoparticles to detect the oil and water zones using sand-pack displacement test. An experiment using the sand-pack method was done to show that the hydrophilic nanoparticles can be used to collect data. The nanoparticles used were aluminum oxide (Al₂O₃) and nickel zinc ferrite oxide (NiZnFeO). The results showed that for NiZnFeO, at 3-inch distance from the injection point, the percentage difference increased from 15% to 25%, while for Al₂O₃, the nanoparticles also showed the same increment but different in values, which were from 6% to 15%. This is shown by the significant change of resistivity percentage at the 3-inch distance. To conclude, the use of both types of nanoparticles that have hydrophilic nanoparticles can show the significant changes for resistivity at internal short front face of well reservoir with oil zone only.

Abstrak

Nanopartikel dengan skala nano boleh digunakan sebagai pengumpul data di setiap bahagian pembangunan bidang petroleum. Dengan adanya keadaan hidrofilik untuk nanopartikel, ia boleh bergerak ke kawasan yang disasarkan di zon air. Keadaan hidrofilik akan membezakan antara zon minyak dan zon air. Objektif kajian ini adalah untuk menggunakan nanopartikel hidrofilik untuk mengesan zon minyak dan air menggunakan ujian pek pasir. Satu eksperimen menggunakan kaedah pek pasir dilakukan untuk menunjukkan bahawa nanopartikel hidrofilik boleh digunakan dalam mengumpul data. Nanopartikel yang digunakan adalah aluminium oksida (Al₂O₃) dan nikel zink ferit oksida (NiZnFeO). Hasil kajian menunjukkan bahawa untuk NiZnFeO, pada jarak 3 inci dari sudut suntikan, perbezaan peratusan meningkat daripada 15% kepada 25%, manakala bagi Al₂O₃, nanopartikel juga menunjukkan kenaikan yang sama tetapi berbeza dalam nilai iaitu dari 6% kepada 15%. Ini ditunjukkan oleh perubahan yang ketara peratusan kerintangan pada jarak 3 inci. Kesimpulannya, penggunaan kedua-dua jenis nanopartikel yang mempunyai nanopartikel hidrofilik boleh menunjukkan perubahan signifikan bagi kerintangan muka depan pendek dalaman takungan baik dengan zon minyak sahaja.
