Avoiding congealing by rerouting high temperature high water-cut wells
Year: 2015
Proceedings Title : Proc. Indon. Petrol. Assoc., 39th Ann. Conv., 2015
Several wells in Balam oil field experience congealing of the waxy crude oil in the flowline, whereby they could no longer deliver fluid to the Gathering Station.
On the other hand, other wells produce at a high water-cut and have a much higher wellhead flowing temperature. These wells were potential sources to increase the temperature of flowlines where congealing occurred.
A jumper line was constructed to divert high temperature fluids into a flowline suffering from congealing. This successfully increased the fluid temperature enough to restore production from the low-temperature well, and increased Balam oil production by 296 BOPD.
