WebAug 1, 2001 · A mechanistic model was developed to predict flow pattern and flow characteristics such as pressure drop and liquid holdup in vertical and deviated wells. The model includes five flow patterns: bubbly, dispersed-bubble, slug, churn, and annular flows. Flow-pattern prediction incorporates the transition models proposed by Barnea 1 (or … WebTurbulent flow for gasified water–based fluids and transitional to turbulent flow for gasified oil–based fluids are expected in the wellbore. Also, as drag force of fluid on cuttings is minimal in a turbulent condition, slip velocity is higher. ...
