.... The key focus of work presented at the MPT 2015 was related to liquid accumulation. However, this work also revealed that frictional pressure drop increases significantly with high water fractions, existing flow models severely under predicts frictional pressure drop at high water fractions...

... shore. The reservoir fluids contain very little condensate and the pipeline flow is typically low liquid loading conditions at high water fractions. The key focus of the work presented at the previous BHR conference in 2015 was related to liquid accumulation. However, this work also revealed...

... that the superficial liquid velocity is small compared to the superficial gas velocity; but the liquid holdup fraction can become significant if the superficial gas velocity is reduced. The focus of this study was to determine the onset of liquid accumulation, i.e. the flow rate where the liquid holdup jumps from...

... topside. It is especially the handling of the water/MEG phase which reaches its limit when the surges become too large. This defines the minimum turn down rate for the flowlines. One has also experienced problems with hydrate formation in the periods between each surge. During the liquid accumulation...

... uncertainties, the flow models may miss severely when compared to field data. In this context a new, non intrusive measurement technique for liquid accumulation has been developed. Theoretical studies, laboratory experiments and field tests have been run in order to verify the technique. The new technique has...
