The operator had tied-in a new satellite field to an existing production facility. Upon production start-up, it was identified that the production from the satellites showed significant instabilities with pressure and flow rate oscillations.
Some of the wells also ceased to flow after a period of unstable production and were subsequently shut down. This production environment caused huge challenges at the process facility topside and it was decided to kick off a debottlenecking project with the mandate of evaluating the cause of this behaviour and propose mitigating options.
With an expected production in the excess of 50,000 bbls of oil per day from the satellites - it was crucial to solve this problem quickly and effectively.
Add Energy's flow assurance experts were contacted to assist the debottlenecking task force.
During this project, our engineers:
Initially, it was believed the unstable production was caused by water entrainment from the reservoir, however, Add Energy demonstrated that this in fact, was not the case, through transient simulations.
Through these simulations, it was identified:
The short-term solution:
The long-term solution:
The operator opted for both long and short term options, which achieved the following results:
