Indonesia memiliki power plants yang tersebar di berbagai daerah baik milik PLN ataupun perusahaan swasta (Non PLN). Setiap perusahaan akan mengemisikan Karbon dioksida (CO2) dari hasil pembakaran pada power plant. Sebagai suatu polutan, CO2 memiliki potensi untuk digunakan pada proses industri seperti Enhanced Oil Recovery (EOR). CO2 EOR merupakan suatu usaha meningkatkan produksi minyak dengan cara injeksi CO2 ke dalam suatu sumur produksi tahap tersier. CO2 EOR dapat diterapkan di Indonesia dikarenakan terdapat beberapa power plants (sources) dan perusahaan minyak (sinks), khususnya di Jawa Timur. Hal ini memungkinkan untuk dapat mendistribusikan CO2 dari sources menuju sinks menggunakan perpipaan. Akan tetapi untuk mengaplikasikannya, dibutuhkan biaya (cost) CO2 captured, perpipaan, dan fasilitas EOR. Cost tersebut bergantung pada jumlah CO2 yang dialirkan, jarak dan teknologi yang digunakan, sehingga dibutuhkan optimisasi dikarenakan adanya variasi jumlah CO2 dan jarak. Dalam hal ini variabel optimisasi yaitu jalur perpipaan dan mass flowrate CO2 captured. Terdapat tujuh CO2 sources dengan kapasitas dan lokasi yang berbeda. Selain itu, terdapat tujuh sinks dengan kebutuhan injeksi CO2 yang berbeda pula. Hasil optimisasi menunjukkan CAPEX dan OPEX minimal. Nilai CAPEX dan OPEX setiap source bergantung pada jarak antara source dan sink beserta jumlah mass flowrate CO2 yang didistribusikan. Adapun source CO2 yang terpilih yaitu source 1,3,4 dan 7. Source yang tersisa (2, 5

This study proposes economic evaluation of CO2 geological storage with enhanced oil recovery. The procedures consider capital expenditures and operating costs of infrastructures and revenues from oil recovery and carbon tax credits. Extensive CO2 geological storage with enhanced oil recovery simulations was conducted to determine the most promising scenario among cases, where miscibility was controlled by the addition of liquefied petroleum gas. The addition of liquefied petroleum gas into a CO2 injection stream can accelerate reduction of oil viscosity, interfacial tension, and oil density, which cause improved displacement efficiency. The larger was the amount of liquefied petroleum gas injected, the greater was the miscibility due to minimum miscibility pressure reduction, resulting in higher oil recovery and less CO2 sequestration. Although liquefied petroleum gas addition enhances the performance of CO2 enhanced oil recovery, economic analysis should be conducted for CO2 geological storage with enhanced oil recovery due to the higher price of liquefied petroleum gas than that of CO2. Net present value decreased from liquefied petroleum gas mole fraction of 0–2% and started to increase from mole fraction 2–13% due to the miscibility effect. Then, net present value started to decrease, because the purchasing and injecting prices of the required liquefied petroleum gas exceeded that of the oil produced. Economic evaluation showed that addition of 13% liquefied petroleum gas was the most promising scenario, with a net present value of 91 MM$. Thus, we confirmed an optimum liquefied petroleum gas concentration in the CO2 geological storage with enhanced oil recovery process.
