With the interactive graphical schematic and templates of the Pipesim steady-state multiphase flow simulator, well models can be created in a thorough, fast and efficient way to help increase production and understand reservoir potential. The Pipesim simulator models multiphase flow from the reservoir to the wellhead and considers artificial lift systems, including rod pumps, ESP, and gas lift. Well performance modeling capabilities in the simulator enables users to:

• Design optimal well completions and artificial lift systems.
• Diagnose problems that are limiting well production potential.
• Optimize production from existing wells by quantifying actions to increase flow rates.

Pipesim steady-state multiphase flow simulator incorporates the three core areas of flow modeling: multiphase flow, heat transfer and fluid behavior. For 40 years, the Pipesim simulator has been continuously improved not only by the latest science in these areas, but also the latest innovations in computing and oil and gas industry technologies.

The Pipesim simulator includes advanced three-phase mechanistic models, rigorous heat transfer modeling and comprehensive PVT modeling options. The ESRI-supported GIS map canvas helps deliver true spatial representation of wells, equipment and networks. Networks can be built either on the GIS canvas or automatically using a GIS shapefile. Rapid well model building and analysis are done with an interactive graphical wellbore. The implementation of a new parallel network solver, which spreads the computational load across all processors results in a faster simulation runtime.
