Abstract

Produksi pasir merupakan permasalahan utama pada reservoir minyak dengan formasi batu pasir tidak terkonsolidasi yang dapat menyebabkan kerusakan formasi, penurunan produktivitas sumur, serta kerusakan pada fasilitas produksi di permukaan. Penambahan nanopartikel Fe₂O₃ ke dalam matriks hidrogel berbasis polyacrylamide-co-acrylic acid-co-2-acrylamido-2-methylpropane sulfonic acid (AM-co-AA-co-AMPS) berpotensi meningkatkan stabilitas struktur gel sehingga dapat diaplikasikan sebagai material chemical sand control. Penelitian ini bertujuan mensintesis hidrogel nanokomposit berbantuan ultrasonik, mengkarakterisasi sifat material, serta menentukan kondisi sintesis optimum berdasarkan variasi daya ultrasonik dan waktu polimerisasi. Sintesis dilakukan melalui polimerisasi radikal bebas menggunakan nanopartikel α-Fe₂O₃ yang didispersikan secara ultrasonik, kemudian dikarakterisasi menggunakan FTIR, XRD, Degree of Conversion (DoC), Equilibrium Swelling Ratio (ESR), Sandpack Test, dan Compressive Strength Test. Hasil FTIR menunjukkan terbentuknya gugus fungsi khas hidrogel, sedangkan analisis XRD menunjukkan material didominasi fase amorf dengan Crystallinity Index sekitar 12%. Nilai Degree of Conversion optimum diperoleh pada daya ultrasonik 70 W sebesar 73,56% dan waktu polimerisasi 10 menit sebesar 77,63%. Kondisi tersebut juga menghasilkan nilai turbiditas terendah sebesar 3,48 NTU, kemampuan swelling terbaik, serta dispersi nanopartikel Fe₂O₃ yang paling homogen. Hasil uji kuat tekan menunjukkan bahwa nilai kuat tekan tertinggi tidak merepresentasikan performa sand control terbaik, melainkan dipengaruhi oleh aglomerasi nanopartikel pada kondisi tanpa ultrasonik. Secara keseluruhan, bantuan ultrasonik pada 70 W selama 10 menit menghasilkan hidrogel nanokomposit dengan karakteristik dan performa chemical sand control terbaik.

Sand production is one of the major challenges in oil reservoirs with unconsolidated sandstone formations, leading to formation damage, reduced well productivity, and deterioration of surface production facilities. Incorporating Fe₂O₃ nanoparticles into a polyacrylamide-co-acrylic acid-co-2-acrylamido-2-methylpropane sulfonic acid (AM-co-AA-co-AMPS) hydrogel matrix has the potential to improve the structural stability of the gel, making it a promising material for chemical sand control applications. This study aimed to synthesize an ultrasonic-assisted hydrogel nanocomposite, characterize its material properties, and determine the optimum synthesis conditions by varying ultrasonic power and polymerization time. The hydrogel nanocomposite was synthesized via free-radical polymerization using ultrasonically dispersed α-Fe₂O₃ nanoparticles and characterized by Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Degree of Conversion (DoC), Equilibrium Swelling Ratio (ESR), Sandpack Test, and Compressive Strength Test. FTIR analysis confirmed the successful formation of the hydrogel network, while XRD analysis revealed that the material was predominantly amorphous with a crystallinity index of approximately 12%. The optimum Degree of Conversion was obtained at an ultrasonic power of 70 W (73.56%) and a polymerization time of 10 min (77.63%). These conditions also produced the lowest sandpack effluent turbidity of 3.48 NTU, the highest swelling capacity, and the most homogeneous Fe₂O₃ nanoparticle dispersion. Although the highest compressive strength was observed in samples synthesized without ultrasonic treatment, this result was attributed to nanoparticle agglomeration rather than superior hydrogel network quality. Overall, ultrasonic-assisted synthesis at 70 W for 10 min produced the hydrogel nanocomposite with the best characteristics and the highest potential for chemical sand control applications in oil reservoirs.
