Abstract

Kabupaten Rembang sebagai daerah yang dekat Blok Cepu yang merupakan lokasi penghasil energi. Penting bagi siswa/siswi pelajar SMKN 1 Rembang sebagai penerus bangsa untuk memperoleh pengetahuan dan wawasan yang terkait dengan energi migas. PEM Akamigas mengambil perannya dalam mengedukasi pelajar SMKN 1 Rembang tentang tahapan produksi migas dan memeragakan cara kerja metode produksi minyak dengan sucker rod pump  dalam bentuk miniatur maket. Jumlah siswa yang mengikuti kegiatan pengabdian masyarakat ini kurang lebih 100 siswa jurusan teknik mesin kelas XI dan XII serta beberapa guru. Metode yang digunakan adalah penyampaian materi dan peraga alat pembelajaran tentang teknik produksi migas. Hasil kegiatan memberikan peningkatan pengetahuan dan wawasan siswa tentang tahapan teknik produksi migas. Antusiasme bertanya dan menjawab pertanyaan dengan lancar serta mampu memeragakan alat peraga sucker rod pump dan sekaligus mampu memecahkan solusi dari studi kasus yang diberikan merupakan bukti peningkatan wawasan siswa dari kegiatan ini.

Abstract

The PT JM Field is capable of producing approximately 133 MMSCFD of gas and 5,600 BCPD of condensate with fluid behavior characterized by retrograde condensation such as mercury-bearing gas systems. These conditions show the importance of filtration in ensuring safe and reliable downstream operations. However, an operational issue was identified in 2024 in the form of an unusually high differential pressure which reached 30 psid across the Condensate Mercury Pre-Filter. The condition was a reflection of partial blockage at the filter outlet and led to a reduction in the system performance. Therefore, this study aimed to identify the root cause through the laboratory analysis of sludge collected during pipeline pigging between the PG and the KCR Gas Plants. The results showed that the GEOPIC sample consisted of 12.03 wt.% solid and 21.52 wt.% liquid fractions while the BIDI2 had 5.70 wt.% and 42.86 wt.% respectively. Elemental analysis also confirmed the presence of C, H, N, S, and Na while FTIR spectroscopy showed characteristic C=N, N–H, and S=O functional groups which were the reflection of a strong similarity to imidazolinamide-based corrosion inhibitors. Ionic analysis further detected Cl⁻, PO₄³⁻, and NH₄⁺ ions in the pigging fluid which were commonly associated with the corrosion inhibitors applied in the system. The results led to the implementation of several mitigation measures such as filter replacement, pipeline pigging optimization, and equipment inspection during the Turnaround (TAR). These actions successfully mitigated sludge accumulation and restored normal filtration performance.
