PRODUCTION OPTIMIZATION OF LOW INFLUX WELL BY INSTALLING ‘LOST PARASITE’ (LOW-COST SEPARATOR ON SITE) IN WELL X-1, Y FIELD

Abstrak

Y Field is a mature field. A common problem in the mature field is that the reservoir pressure is depleted, some wells experiences low influx that the production fluid cannot reach the gathering station. Low influx wells can be produced by flowing the production fluid to TOS (Tank on Site) expecting that the fluid can come out due to changes in pressure differences. However, due to the limited number of TOS, TOS is only used for wells that have considerable potential, therefore, an alternative to TOS is needed. LOST PARASITE (Low-Cost Separator on Site) is an alternative to TOS. The LOST PARASITE itself is made of an idle vessel that have been modified so that it can be filled with liquid (oil & water) and gas. If the liquid (oil and water) in LOST PARASITE is full, then the water will flow into the flowline through the tube inside the LOST PARASITE with capillary system and the oil is trapped in LOST PARASITE. Furthermore, the oil will be transported using vacuum trucks and sent to the main gathering station. The low influx well then could be produced continuously using LOST PARASITE and it can be considered to be used in other low influx well that have been suspended because the production fluid could not reach the gathering station.
