... of production generally falls into two categories of challenge, namely: Hydrodynamic Chemical - Thermodynamic Hydrodynamic Phenomena The laying of pipelines and flowlines over undulating terrain results in pipeline configurations that incorporate inclined sections of pipe as well as dips. Both...

... wellhead pressures of 1,000-2,000 psig due to the backpressure added by the long multiphase flowline. In addition, operating as such a continual high backpressure has been shown to have a direct impact on production decline behavior, acting to reduce ultimate recovery (Martin & Scott, 2002...

.... Increasingly, multiphase flow becomes an issue in field flowlines and gas transmission lines due to the drive for field facilities minimization. In an effort to reduce facilities cost, gas treatment is held to a minimum. This drive is particularly intense offshore where topsides facilities space and weight...
