N2 - This paper discusses energy audit in operating oil and gas production facility in Indonesia by taking a case study at Field Y, East Kalimantan. Energy audit is essential to be carried out in order to identify current rate of efficiency and energy intensity in oil and gas production facility, and extrapolate the data as baseline to recommend potential room for improvement in increasing efficiency. Calculation on efficiency and energy intensity has been performed against main equipments which consumes fuel gas, namely generators and turbo compressors. Data from 2015-2017 were collected to perform the calculation. Calculation results showed that generator thermal efficiency ranges from 13.54% - 17.45%, which was affected by generator load power itself. The efficiency improves as the load power increases. Meanwhile, compressor thermal efficiency ranged from 28.36% - 33.79% depending on process variables and compressed gas volume. Energy intensity calculation result showed the value of 64.554 - 71.064 and greenhouse gas emission ranged from 160.48-208.17 kt CO 2 eq. From this study, it is identified that improvements to increase efficiency and reduce energy intensity can be made through operating one generator and one compressor, and assessing the use of renewable energy resources to supply power requirement for non-process facilities on site.
