GasPipe

GasPipe is an easy to use package used for generating IPR curves for all nodes and

components in a gas gathering system. The network consists of wells, separators,

lineheaters, dehydrators, meter runs, field compressors, gas processing plants and

pipelines. With this package the user can optimize a gathering system, determine system restrictions and investigate flow improvements.

GasPipe Network

• The Network consists of a series of nodes.

• Wells, separators, lineheaters, dehydrators, meter runs, field compressors, gas-processing plants and delivery stations.

• Nodes are connected with pipelines.
