.... The key focus of work presented at the MPT 2015 was related to liquid accumulation. However, this work also revealed that frictional pressure drop increases significantly with high water fractions, existing flow models severely under predicts frictional pressure drop at high water fractions...

..., only the data with USL = 0.2, 0.8, 1.4 and 2.0 m/s are presented here. Figure 8 presents the frictional pressure drop and the liquid holdup against the superficial gas velocity. The experiments were performed at two pipe inclinations, 0 and 4 degrees. To better illustrate the pipe inclination influence...

... that frictional pressure drop increases significantly with high water fractions, existing flow models severely under predicts frictional pressure drop at high water fractions, and they are not able to predict the effect of water fraction on the frictional pressure drop little experimental data exist...

.... The measurements show that the frictional pressure drop is very sensitive to the water cut in these circumstances, even though the estimated liquid content is typically less than 1%. For instance, at 50% water cut, the frictional pressure drop in the near-horizontal 8" pipe was found to be up to 30% higher than...

... predictions using the OLGA2000 steady state code, OLGAS (version 3.02). Results from the model comparison indicate that the model under-predicts both water accumulation and frictional pressure drop, particularly at high inclinations. 1 INTRODUCTION In the oil and gas industry, multiphase flow occurs...
