Multiphase Metering in Siberian Gas and Condensate Wells –Lessons Learnt in Multiphase Well Testing Operations Since 2006

A number of multiphase flowmeters were recently deployed in the Yamal peninsula in Northern Siberia to perform<br>multiphase measurements of the rates of gas and condensate wells. The utilization of multiphase flowmeters in wet<br>gas and condensate wells is relatively new, and significant progress have been made in the understanding and the<br>quantification of multiphase flowmeter uncertainties in flow loop. Little field experience is documented to date and<br>this paper presents field data in this very challenging domain.
