Flow assurance is relatively new term in oil and gas industry. It refers to ensuring successful and economical flow of hydrocarbon stream from reservoir to the point of sale and is closely linked to multiphase flow technology.
Flow assurance developed because traditional approaches are inappropriate for deepwater production due to extreme distances, depths, temperatures or economic constraints. The term Flow Assurance was first used by Petrobras in the early 1990s in Portuguese as Garantia do Escoamento (pt::Garantia do Escoamento), meaning literally "Guarantee of Flow", or Flow Assurance.
Flow assurance by definiton focuses on the whole engineering and production life cycle from the reservoir through refining, to ensure with high confidence that the reservoir fluids can be moved from the reservoir to the refinery smoothly and without interruption.

- Pressure support consideration
It is necessary for sufficient pressure to be available to transport the hydrocarbons at the
required flow rates from the reservoir to the processing unit. Matters
that require consideration in this regard include:
1. Pressure loss in flowlines
2. Separator pressure setpoint
3. Pressure loss in wells
4. Artificial lift method selection
5. Remote multiphase boosting
6. Drag reduction
7. Slugging in horizontal wells
8. Gas lift system stability
9. Interaction with reservoir performance
