Total E&P Indonesie (TEPI) operates 4 processing stations in the Mahakam delta to process Gas and Liquids produced by PSC Mahakam fields. These stations require Gas to Fuel 22 Gas compressors, 10 electric generators, 7 heaters and Boilers. There are 16 Flare points. Besides, 2000 wells are operated on the PSC and produce from 100 gathering and testing satellites, platforms and clusters where regular offloading, flaring and venting occur. In 2015, TEPI wellhead Gas production was 1772 MMscfd, which corresponds to 647 Bcf of Gas treated. Out of these 647 Bcf, 30 Bcf were consumed for operational and safety purpose, in stations and well platforms. It corresponds to 4.6% of TEPI Gas production and this consumed Gas is compulsory to produce. In terms of LNG, it is equivalent to 9 cargos that would have been valorized quarter a billion US dollars on APAC Gas market. Why Fuel & Flare prediction tool? Any Gas producer faces the issue of inaccurate Fuel and Flare (F&F) prediction at some point. When large quantities are involved, such as in TEPI, understanding correctly and being able to reproduce Fuel and Flare Gas consumption allows decreasing the uncertainty of their provision, thus improving robustness of Gas production forecasts. This is a key for commercial, development, environmental, reserves estimation or new business purposes. What does the tool consist in? More a method than a tool itself, TEPI Fuel and Flare Gas workflow was developed transversally by the Gas Management team with input from reservoir, process, field operation, development and environmental engineers. Indeed, the difficulty of F&F prediction resides in its rather ‘borderline’ aspect for all the disciplines involved. Asking a reservoir engineer to address compressor availability constraints in his forecasts is as odd as asking the field operation engineer to provide it for… 2026!
