..., which requires a set of closure relationships of other slug characteristics. To select the proper set of closure relationships, a numerical optimization is carried out using a large slug length dataset to minimize the prediction error. Thousands of combinations of various slug flow closure relationships...

..., and dispersed bubble. For horizontal flows, there are seven kinds of flow patterns: stratified smooth, stratified wavy, elongated bubble, slug, annular, wavy annular, and dispersed bubble ( Shoham, 2006 ). Very often, in offshore fields, the production of oil and gas follows the slug flow pattern. The path...

Currently, the practice for many operators is limited to visually observing gas and liquid production volumes. When...

... To study the slug flow and stratified flow in the undulating wellbores, Kokal and Stanislav (1986) established a model by dividing the flow into two sub-layer staggered flow. However, this assumption brings difficulties to the model solution because of the need to obtain measurements of shear...

...Abstract Abstract Multiphase flow occurs in wellbores during the production of oil and gas. Depending on the physical forces and interactions acting on different phases, there can be various phase distributions in the pipes, known as flow patterns or flow regimes, such as bubble flow, slug flow...
