hi depster...do you know anything about flow assurance eng.? would appreciate if you can enlighten me on the prospects as compared to pipeline eng...
I am not from Subsea or Subsurface... but here's the definition,
"Flow assurance [1] [2] is a 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. The term was coined by Petrobras in the early 1990s in Portuguese as Garantia de Fluxo, meaning literally “Guarantee the Flow”, or Flow Assurance.
Flow assurance is extremely diverse, encompassing many discrete and specialized subjects and bridging across the full gamut of engineering disciplines. Besides network modeling and transient multiphase simulation, flow assurance involves effectively handling many solid deposits, such as, gas hydrates[3], asphaltene, wax, scale, and naphthenates. Flow assurance is most critical task during deep water energy production because of the high pressures and low temperature (~4 degree Celsius) involved. The financial loss from production interruption or asset damage due to flow assurance mishap can be astronomical. What compounds the flow assurance task even further is that these solid deposits can interact with each other[4] and can cause catastrophic blockage formation in pipelines and result in flow assurance failure."
Since I'm from Topside, it only concerns me when the hydrocarbon flow is meeting the specific export equipments "minimum flow" requirement to prevent damages to the rotating equipments like gas compressors, condensate pumps, crude oil pumps etc, whether in full recycling, partial recycling or export mode of operation. If u r talking about flow assurance at the well head, etc, u better ask the subsea or subsurfacers... topside-wise, flow assurance control is taken care by NPSH, NPSHr, recycling CV sizing.. what we normally face is impurities in hydrocarbon from either carbonate of shallow clastic wells are silica (sands) which turns out to be corrosive to the rotating equipments internals..
Normally the NPSH is addressed by the piping layout, where the pipeline engineers will come into the picture.
