Paper Number: BHR-2005-H3
... to design quite confidently new pipelines or anticipate behaviors of existing pipelines. Indeed a gap was still to be filled in as flows are very seldom constant with time. This gap is partly closed with the transient multiphase flow simulators which can simulate unsteady flows of oil, gas and water...

.... Reducing the level of the volume balance threshold will produce false alarms whenever a significant transient occurs on the pipeline. In longer time periods, the effects of transients which are short in duration are minimized. Periods of 30 minutes to an hour are not uncommon to detect large leaks and line...

... a consequence of the residential consumption behavior. Thus, understanding the expected PP operations means having a better knowledge about pipeline design. In case of networks without NG storage facilities, the design requirements and operational parameters are strongly linked with a right understanding...

... is affected by liquid fall back from the vertical section and lateral section length. Slug characterization along the well is critical to properly design and operate downhole and surface equipment and properly predict pressure gradient and liquid holdup along the well. Finally, multiphase flow transient...

... was further increased to high shear rates (~250 s-1). This behavior is best described using a power law equation where at high enough shear rates the fluid no longer has a shear rate dependency. From an application stand-point, the effect of shear rate on emulsion viscosity may be important during transient...
