AFS believes the key to any flow assurance development is a keen understanding of the fluid properties. Or more often, an understanding of the uncertainties associated with available information, as well as the flexibility to incorporate changes in the fluid properties within the system design. AFS prides itself on its production chemistry background, which forms the foundation upon which key project decisions are made.

- Chemical inhibitor selection
Flow assurance is a challenging, multi-disciplinary science that requires knowledge of fluid hydraulics, heat and mass transfer, separations, and reaction kinetics—often with limited fluid information—as well as dealing with each in a transient/dynamic state that can change rapidly. Compounding the issue is that many of the hydraulic/thermal challenges occur over hundreds of miles or thousands of feet below the water, with limited access to fix problems after a system has been installed. Proactive and up-front addressing of key issues is a pre-requisite for proper system design provisions.
- Flow assurance
- Multiphase flow
- Transient thermal/hydraulic simulations
- Operating philosophy / guidelines
- Thermal/hydraulic requirements
- Integrated production modeling (assess impact on reserves)
- Hardware assessment
- Systems integration (but not actual “testing”)
As field developments get more and more complex, through either challenging environments or developments to existing infrastructure, a systems approach is essential to deliver a quality solution that will work when moving from engineering phase of a project into operations. Taken in isolation, production chemistry and flow assurance provide two key inputs to any given project—but without integration with other disciplines, their value is greatly diminished. Incorporating reservoir, flowline/pipeline, riser, facilities, material, and operational constraints—to deliver a total system—is where AFS provides value to our clients.
