Diverging Network Systems

Maximus is able to solve diverging network systems just as well as gathering systems. The example presented here is of an injection system supplying water to a reservoir’s aquifer. Water, from a source, flows along a 1km flowline to a manifold where it is split among three injection wells. The split between the wells depends in the hydraulic characteristics (i.e. choke settings, tubing size and elevation change, injectivity and local reservoir pressure) of each of the wells. Please note that for clarity the production system is omitted from this model.

Another class of diverging network systems arises when a separator is included in a model. Maximus is able to model both two-phase and three-phase separators using its generalised approach to network modelling and, unlike some other simulators available on the market, Maximus is not forced to ‘throw away’ all but one stream emanating from a separator. In Maximus, all outlet streams produced by a separator can be processed through downstream parts of the network as shown the following typical topsides processing arrangement:
