Teodoriu, “Hydraulic analysis of gasoil- sand flow in horizontal wells,” in Society of Petroleum Engineers The emulsion viscosity was determined using a viscometer of concentric cylinders type Miltifasico RC, while density and mass flow rate were quantified using a Coriolis flow meter. Ghalambor, Petroleum Production Engineering. American Petroleum Institute,pp. The flow pattern map is generated using a home made code developed by the authors applying ,,,,. Belandria glujo the effect of solids in non-aqueous foam with mineral oil viscosity up to 0.
The total pressure drop depends on friction lost, height and acceleration of ttuberias fluid. Different flow pattern maps for different angle inclination was used by : Experimental and Regime Map.
Physicochemical and Engineering Flujl. Neither Morales-Ruiz et al. The experimental facilities are composed by two horizontal flow loops with different diameters 0. A general equation that shows sources of the pressure drop in steady state is written in 1.
S hresthaL. Another mechanistic model was defined by , this model took into account the following flow patterns: The classical two fluid model defines a set of closure relations for each flow pattern and needs a previous flow pattern selection.
Flujo Multifasico III : Flujo Vertical & Flujo Inclinado
They are developed to obtain a representative value of the velocity and the pressure in a given region. They found that there is an optimum concentration of water at which the stability of the foam increases, and small quantities of water and surfactants produce a drastic change in the foaminess of the oil.
The size of the bubbles increases as coalescence progresses, 15 minutes later the shape of the bubbles in the foam were mostly spherical, covered by a liquid film, with bubble size in the order of several millimeters and it was possible to differentiate two zones: This is due to the significant reserves of heavy and extra-heavy oil EHOand the imminent production of gas and water caused by water coning or channeling in reservoirs or to vapor injection as predominant enhanced oil recovery method for oil production.
An example of a drift flux model developed in this period of time was done by . Regarding flow pattern, an example of a wrong selection of flow pattern at high pressure was given by , in which, annular flow is predicted when churn, slug and dispersed bubble flows are also possible. The change of phase term is used by ,,, and it is assumed negligible by ,,,,. An extension of a model developed in  was proposed by . Moreover, the Choi et al.
They find first the void fraction with a representative liquid mixture and then, they calculate the holdup of every liquid. For that reason, conservative equations are applied to the mixture as a homogeneous model  with a slippage.
There is not a method to predict properly wellbore performance in all cases. Finally, new commercial software was created to solve these equations. Results on deviated wells were not satisfactory.

They also developed a model based on them. Its simplicity imply that solution can be found fast.
An example of three methods to select flow pattern is shown in the Figure 1. In these works a thermal analysis is also carried out. The operational conditions used in this study are presented in Table 2. The large scale models are chronologically classified as:
