... ABSTRACT Local heating of subsea flowlines is a new technology block which can improve the economics of new field developments. Heating the flowlines is a way to overcome the thermal constraints, mitigate hydrate & wax risks and provide operational flexibility. Indeed in the case of long...

... costs. The interest in lowering the number of flowlines to only a single gas export line with the use of subsea processing solutions (gas/liquid separation with liquid boosting and/or gas compression) will be explained. Replacing the mono-ethylene glycol (MEG) injection network by an anti-agglomerate...

... Abstract The aging of petroleum wells causes reduced reservoir pressures and increased hydrostatic head of liquid in the production tubing and flowlines. Although foamer applications to unload liquids are common in gas fields, these foamers were found to be unsuitable for oil well applications...

... ABSTRACT The entire Project for the disconnection and demobilization of the FPSO was managed in four stages. The first two stages were related to shutdown of the production, flushing of all flexible flowlines and preparing the FPSO for the disconnection by cleaning the topsides, disconnecting...

... Abstract Deepwater fields are particularly prone to severe hydrate issues. Hydrate formation may cause significant production losses and, in worst cases, expensive offshore operations to replace completely plugged subsea flowlines. The experience hereto described is related to a deepwater oil...

In addition, careful operational mitigations were implemented resulting in significant reduction in the slug frequency and density variations. The results suggest that topside choking to increase flowline back pressure is a very effective...
