... equation to solve, uses an explicit equation for liquid holdup prediction thus reducing computation time significantly. Coupled with some simplified assumptions on PVT, such simple form of liquid holdup prediction formula enables analytical integration of pressure gradient in two-phase flow along the pipe...

.... Recognizing these behaviors downhole is a complex process that requires a greater number of data points, fluid samples and associated laboratory analysis. Pressure gradients with wireline formation testers are traditionally used to evaluate fluid density, fluid contacts, and layer connectivity in exploration...

.... With this hybrid model it is determined the flow pattern, under stationary conditions, and hydrodynamic characteristics of the flow pattern, mainly hold-up and pressure gradients. An analysis of synthetic information, generated with the computer program, has been done. Based on statistical parameters...
