Abstract

Carbon Capture, Utilization, and Storage Enhanced Oil Recovery (CCUS-EOR) merupakan solusi untuk meningkatkan produksi crude oil sekaligus mendukung pengurangan emisi karbon pada industri migas. Penelitian ini bertujuan untuk mengevaluasi kelayakan teknis dan keekonomian implementasi pilot project CCUS-EOR pada Lapangan X menggunakan metode Analytical Hierarchy Process (AHP) - TOPSIS. Metode AHP digunakan untuk menentukan prioritas pemilihan sumber CO₂ berdasarkan empat kriteria utama, yaitu kualitas dan spesifikasi CO₂, reservoir dan kapasitas suplai CO₂, jarak dan kebutuhan transportasi, serta operasional dan risiko. Hasil evaluasi menunjukkan bahwa kualitas dan spesifikasi CO₂ menjadi kriteria paling dominan dengan bobot sebesar 55,8%. Hasil analisis teknis menunjukkan bahwa implementasi CCUS-EOR pada Lapangan X layak dilakukan dengan kebutuhan fasilitas tambahan berupa compression system, dehydration unit, booster compressor, dan pumping system. Hasil analisis tersebut telah divalidasi melalui kajian teknis dan keekonomian berdasarkan data operasi, desain fasilitas, serta parameter ekonomi yang digunakan dalam penelitian. Proyeksi CO₂ yang diinjeksikan pada Lapangan X sebesar 106.966 tCO₂ per tahun dan implementasi CCUS-EOR diproyeksikan mampu meningkatkan produksi minyak sebesar 146.000 barel per tahun. Analisis keekonomian menunjukkan bahwa implementasi CCUS-EOR memiliki potensi ekonomi yang baik dengan total revenue sekitar USD 11,62 juta per tahun yang berasal dari incremental oil production dan carbon credit. Dengan CAPEX sebesar USD 12,63 juta dan annual OPEX sebesar USD 1,77 juta, proyek menghasilkan cumulative discounted cash flow sebesar USD 4,45 juta pada akhir tahun kedua operasi. Hasil evaluasi Levelized Cost of CO₂ (LCO₂) sebesar –USD 27,6/tCO₂ stored menunjukkan bahwa proyek tidak hanya mampu menutupi biaya penanganan CO₂, tetapi juga memberikan keuntungan ekonomi. Selain itu, kajian risiko menunjukkan bahwa tidak diterapkannya CCUS-EOR berpotensi menurunkan oil recovery, mempercepat penurunan produksi lapangan, meningkatkan ketergantungan terhadap aktivitas flaring, serta menghilangkan peluang pengurangan emisi karbon melalui penyimpanan geologis, sehingga implementasi CCUS-EOR memberikan manfaat yang signifikan dari aspek teknis, operasional, ekonomi, dan lingkungan.

Carbon Capture, Utilization, and Storage Enhanced Oil Recovery (CCUS-EOR) is a promising solution for increasing crude oil production while supporting carbon emission reduction in the oil and gas industry. This study aims to evaluate the technical and economic feasibility of implementing a pilot-scale CCUS-EOR project in Field X using the Analytical Hierarchy Process (AHP) -TOPSIS method. The AHP method was applied to determine the priority of CO₂ source selection based on four main criteria: CO₂ quality and specification, reservoir and CO₂ supply capacity, transportation distance and requirements, and operational and risk aspects. The evaluation results indicate that CO₂ quality and specification is the most dominant criterion, with a weighting factor of 55.8%. The technical analysis demonstrates that the implementation of CCUS-EOR in Field X is technically feasible, requiring additional facilities including a compression system, dehydration unit, booster compressor, and pumping system. The technical and economic assessment results were subsequently validated through engineering design evaluation, operational data analysis, and economic feasibility assessment. The projected CO₂ injection rate for Field X is approximately 106,966 tCO₂ per year, while the implementation of CCUS-EOR is expected to increase oil production by approximately 146,000 barrels per year. The economic analysis indicates that the proposed CCUS-EOR project has strong economic potential, generating total annual revenue of approximately USD 11.62 million from incremental oil production and carbon credits. With an estimated CAPEX of USD 12.63 million and an annual OPEX of USD 1.77 million, the project generates a cumulative discounted cash flow of approximately USD 4.45 million by the end of the second year of operation. Furthermore, the net Levelized Cost of CO₂ (LCO₂) of –USD 27.6 per tCO₂ stored indicates that the project not only covers the cost of CO₂ management but also generates economic benefits. In addition, the risk assessment indicates that failure to implement CCUS-EOR may result in lower oil recovery, accelerated production decline, increased dependence on gas flaring, and the loss of opportunities for permanent geological CO₂ storage. Therefore, the implementation of CCUS-EOR provides significant benefits from technical, operational, economic, and environmental perspectives.
