Paper presented at the International Oil Conference and Exhibition in Mexico, June 27–30, 2007
Paper Number: SPE-108752-MS
... Abstract A theoretical and experimental study of a normal (hydrodynamic) slug flow in a pipeline-riser pipe system is presented in this paper. Experimental flow visualization revealed that long hydrodynamic slugs generated in the pipeline do not dissipate in the riser pipe. It was shown...

Paper Number: SPE-108506-MS
.... This procedure is usually used to speed-up calculation of bottom-hole pressure for large number wells for oil production optimization purposes 4 . Drift-flux approach can predict liquid holdup for bubbly flow quite accurately. But for slug flow, it usually underestimates the void fraction. Since slug flow...

... the drift-flux approach to predict the gas void fraction in bubble and slug flow. However, for the slug flow, this represents a simplification that does not rigorously consider the difference in the drift-flux between the liquid slug and the Taylor bubble, so inaccurate predictions may be expected from...

Paper Number: SPE-74359-MS
...Introduction The slug structure is a common and complex two phase flow pattern. It consists of a region of liquid with entrained gases, referred to as the liquid slug body; a gas bubble or pocket, and a liquid film. Figure 1 shows the slug flow pattern in the case of horizontal flow...

... was effective in reducing the average pressure drop significantly for all superficial liquid and gas velocities in both slug and annular flow. The average pressure drop reduction of up to 82% for slug flow and 47% for annular flow was achieved. For slug flow, the effectiveness generally decreased with increase...

... Abstract Understanding the behavior of multiphase flow in pipelines is an important factor in the safe and economical design and operation of multiphase systems. Slug flow is a common and very complex occurrence in these pipelines. Sixty-two slug-flow tests were conducted over varying...
