Abstract

The upstream oil and gas industry is under global pressure to reduce carbon emissions while maintaining production levels. One of the key technologies projected to play a vital role in this energy transition is Carbon Capture and Storage (CCS). This technology captures carbon dioxide (CO₂) emissions from industrial activities and stores them in underground geological formations, including depleted oil and gas reservoirs. Indonesia, as an oil-producing G20 member, has a significant opportunity to develop CCS due to the availability of geological formations suitable for carbon storage. This study aims to identify the potential, challenges, and implementation strategies of CCS in Indonesia’s upstream oil and gas sector through a literature review and conceptual analysis approach. The findings indicate that CCS implementation could support Indonesia’s Net Zero Emission 2060 target, although challenges remain in terms of financing, regulatory framework, and technological readiness. Strategic efforts such as policy strengthening, cross-sector collaboration, and human capital development are essential to accelerate CCS deployment.

Abstract

Surfactant flooding is an Enhanced Oil Recovery (EOR) technique aimed at improving oil displacement efficiency by reducing the interfacial tension (IFT) between oil and water. This study investigates the performance of palm oil–based Methyl Ester Sulfonate (MES) surfactant combined with 96% ethanol as a co-surfactant for EOR applications. The surfactant formulations were prepared at MES concentrations ranging from 0.5% to 2.0% and evaluated through density, viscosity, aqueous stability, phase behavior, interfacial tension, and coreflooding experiments. The aqueous stability test showed that all formulations remained clear without precipitation, indicating good thermal stability. Viscosity measurements showed that solution viscosity increased with higher surfactant concentrations but consistently declined as the temperature rose from 30 °C to 60 °C. Phase behavior analysis demonstrated that ethanol enabled the formation of emulsions at all concentrations, with middle-phase microemulsions observed at MES concentrations of 1.25% and 1.5%. The largest middle-phase emulsion volume of 3.00% was obtained at 1.25% MES, indicating the optimal formulation. Interfacial tension measurements showed a reduction to 0.521 mN/m, confirming the effectiveness of the co-surfactant in lowering IFT. Coreflooding results indicated that surfactant injection yielded an incremental oil recovery factor of 29.24% over conventional waterflooding, achieving a total cumulative recovery factor of 45.90%.
