... to effectively set all local constraints at various measured depths. This paper describes special constructs called "boundary segments" with a similar set of flow rate and pressure control modes to those available for tubinghead or bottomhole well control. In a multisegment well model whose topology consists...

... While these two approaches are topologically the same, there are differences in computational efficiency and also in the risk and effort of implementation. Adding Looped Flowpaths to the Multisegment Well Model The multisegment well model is an advanced well modeling feature that allows...

... The multisegment well model reported by Holmes et al . 18 was originally implemented in a black oil simulator. It uses four main variables: G T ,F w , F g , P . These are, respectively, a total fluid flow rate through the segment, weighted fractional flows of water and gas, and pressure...
