... the Middle East. This triggered offshore activities with the need to transport oil and gas simultaneously in pipelines over great distances to shore. At that moment a lot had been achieved on multiphase flow in production tubing, triggered by the pioneering work in 1963 by Duns and Ros with their flow...

... geothermal pipelines off support, and runaway hydrate plugs have caused fatalities. The flow – structure interaction is therefore of interest to study and to incorporate in dynamic simulators. Several cases of dynamic slug flow-structure interactions have been studied in small scale laboratory. A two way...

Paper Number: BHR-2018-185
... ABSTRACT Design and operation of gas-condensate pipelines presents many challenges to the flow assurance engineer and pipeline operator. Important challenges are accumulation during low production and the removal of liquid during a ramp-up operation. Previously the connection between...

Introduction The combination of declining reservoir pressure and increasing water production in aging fields along with certain common pipeline/riser geometries can create or exacerbate riser slugging. The severity of riser slugging typically becomes worse with increasing riser height and may...

This behaviour is characterized by a non-monotonic change in quality with respect to pressure so that in the retrograde region the amount...
