“…Many authors have studied two-phase flow systems due to their importance in several industrial processes (Foletti et al, 2011). Since most reservoirs produce oil and gas simultaneously, the two-phase flow also occurs in the petroleum transport ( Thomas et al, 2001).…”

“…Low-viscosity fluids such as water and air are the most common fluids used in test facilities to build those maps. Despite the good agreement between empirical data and the experimental results in air-water systems, empirical maps at times have failed to predict flow patterns satisfactorily for systems with highviscosity fluids such as heavy oil and gas (Foletti et al, 2011). To account the properties of the fluids, one may use the flow map developed by Baker (1954), in which the flow pattern is a function of non-dimensional parameters.…”

Two-phase flows are of fundamental importance in the petroleum industry, considering that most petroleum reservoirs produce oil and gas simultaneously. Because system pressure gradient is a result of the frictional effects between fluids and pipe wall, and the interfacial effects between the fluids themselves, the precise determination of this parameter is complex. Many authors have sought to predict pressure gradient by using computational fluid dynamic techniques and empirical correlations. The present work aims to compare heavy oil and natural gas mixture pressure gradients in a horizontal pipe for different flow patterns using the application ANSYS CFX 13.0, Lockhart and Martinelli, and Beggs and Brill correlations. The analysis investigated the results for bubbly, plug, and stratified flows. The results showed that Beggs and Brill over predicted pressure gradient values. It was also observed a good agreement between numerical and Lockhart and Martinelli correlation for bubbly and plug flows, with root-mean-square deviations (RMSD) of 5.78 and 19.55 percent, respectively. As for the stratified flow cases, the numerical results presented a poor agreement, with a RMSD greater than 90 percent. The high percent deviation for this flow regime is due to the increase in the gas input content. To compute the high gas velocity effects and, hence, improve the agreement, we suggest the use of turbulence and free surface models as well as different values of drag coefficient in the numerical setup.

“…Once again, the similarity between the numerical slug statistics from each interfacial friction factor expression is remarkable in (Gokcal, 2008;Foletti et al, 2011), very different from the 1.45 obtained. It is important mentioning that for such laminar flows, the velocity in Eq.…”
