Paper presented at the BHR 19th International Conference on Multiphase Production Technology, June 5–7, 2019
Paper Number: BHR-2019-291
... ABSTRACT Two-phase flow in vertical wells is a common occurrence in oil and gas production. High-liquid viscosity two-phase upward vertical flow in wells and risers presents a new challenge for predicting pressure gradient and liquid holdup due to the poor understanding and prediction of flow...

Paper Number: BHR-2015-F2
... flow pattern is experiments and improved mathematical models that predict both the flow pattern transitions and the slug flow characteristics. To this end, an experimental study of three different gas/liquid systems is made which includes liquid viscosities of 0.001 Pa.s, 0.418 Pa.s, and 0.996 Pa.s...

... ABSTRACT Slug flow is one of the commonly encountered liquid and gas two-phase flow patterns. The accurate prediction of its behaviours is crucial for practical engineering applications. Liquid viscosity and pipe diameter are found to have significant impacts on slug frequency, but available...

... understood and inadequately predicted. The objective of this study is to experimentally investigate the effect of high liquid viscosity on slug liquid holdup in horizontal pipes and develop a simple physical model. In addition, a new empirical non-linear regression correlation is proposed to predict...

... understand and quantify the effect of liquid viscosity on slug length and develop two-phase slug length model for high oil viscosity. The developed slug length model can improve the existing two-phase flow models in the development and maintenance of heavy oil fields. Experimental high viscosity (0.181-0.589...

... and show that the phenomenon under investigation is more complex than expected. In particular it has been found that for large liquid viscosity, the bubble drift velocity decreases along the pipe. This result, which can be easily justified on a theoretical ground, poses some clear limitations to the use...
