Paper presented at the 11th North American Conference on Multiphase Production Technology, June 6–8, 2018
Paper Number: BHR-2018-125
... along the loop, visual observations at a given position and monitoring of the overall free gas compositions and consumption. Firstly, a comparison of the two AA additive performances is presented under stratified flow. The two additives showed different behaviours regarding hydrate formation kinetics...

Paper presented at the 9th North American Conference on Multiphase Technology, June 11–13, 2014
Paper Number: BHR-2014-D4
... Abstract Transport of solids produced with oil and gas is desired to avoid flow assurance problems. Stratified flow is a challenging flow regime for solids transport because the solids are trapped in the relatively slow-moving liquid film. Our analysis revealed discrepancies between...

Paper presented at the 8th North American Conference on Multiphase Technology, June 20–22, 2012
Paper Number: BHR-2012-A007
... 1 ABSTRACT: An experimental study on wave characteristics and stratified to non-stratified transition for downward (-2°) two-phase flow and highly viscous oil ( μO =181 cP) is presented in this study. Gravity and 2D waves have not been observed for high viscous oil-gas stratified flow...

Paper presented at the 7th North American Conference on Multiphase Technology, June 2–4, 2010
Paper Number: BHR-2010-F1
... ABSTRACT Computer simulations of two-phase gas-liquid pipe flow cases have been performed with the commercial code STAR-CD using the VOF method and the results are illustrated in this paper. Computed pressure losses for stratified flow and stratified-wavy flow and time-averaged liquid levels...
