... are functions of Reynolds number and relative roughness of the walls. Churchill's (1977) equations are used to calculate the friction factors across the transition from laminar flow to turbulent flow. The representative Reynolds numbers in the impeller and diffuser respectively are (3) R e I = ρ...

... Abstract Uncertainties in design considerations are usually attributed to unknown data in new wells, or unknown conditions from using the wrong model of calculation. This issue is exacerbated in extended, undulated horizontal wells, drilled in high productivity formations, with multiphase flow...

... by combining expert knowledge, data analysis with model-based calculation in pursuit of extreme efficiency and high accuracy. Our efficient workflow builds from intelligent data pre-processing capabilities, which facilitate fast and structured analysis of complex datasets. The metrics and scoreboard...
