WebFor oil-water mixtures, the most common regimes are bubble flow, slug flow and emulsion flow. In horizontal wells, there may be stratified or wavy stratified flow in addition to many of the regimes observed in vertical wells. WebThe flow regime map comprises different zones according to bubble coalesce phenomena. The isolated bubble (IB) regime is characterized by higher bubble generation rate compared to bubble coalescence rate. Either or both bubbly flow and slug flow appear.
