Studi Management Distribusi dan Injeksi Uap pada Lapangan Minyak Berat fn Cekungan Sumatra Tengah

---

Steam flooding management is required to obtain optimal production, so that hot steam that is distributed and injected does not experience under-injected or over- injected conditions. This is determined in the FN heavy oil field which has a type of field that is integrated between steam generators, the distribution of hot steam is a challenge that must be considered in the steam injection distribution process, the loss of heat energy (heat loss) is due to the distance of the distribution process from the steam generator to the injection wells, . To find out the suitability of the steam supply from the steam generator which is distributed and injected into injection wells, a study was carried out using secondary data from the FN heavy oil field in 2022 related to the steam generator, steam rate measurement, steam pressure monitor, and latent heat target data. Latent heat ratio is the result of calculating the target latent heat divided by the latent heat SPM. The latent heat ratio is categorized as comply if it shows values > 0.85 and ? 1.30 then the latent heat ratio is categorized as not comply if it shows values ? 0.85 and > 1.30. Management target latent heat is set higher for injection wells whose area is in the mature zone category which is located in the south while for the immature zone it is located in the north. If the latent heat ratio is ? 0.85 then the pressure must be increased but if the latent heat ratio is > 1.30 then the pressure must be reduced so that the latent heat ratio becomes complied. Based on the research conducted, it was found that the performance of the steam generator experienced a discrepancy in the management of steam production at COGEN and WHRU due to maintenance on the steam generator on August 25 2022 – December 17 2022 which is normally used to supply steam to the north area (COGEN) was replaced with a steam generator in the south area (SS and WHRU) and the steam generator that is normally used to supply steam to the south area (WHRU) was replaced with a steam generator in the south area (SS and COGEN) which is in the south and north area. This resulted in 1720 active injection wells experiencing a latent heat ratio that did not comply under injection of 18% consisting of 212 injection wells, of the 212 injection wells 70% in the north area and 30% in the south area and not comply over injection of 2% consisting of 24 injection wells, of the 24 injection wells 30% in the north area and 70% in the south area.
