Modern production systems require designs that ensure safe and cost-effective transportation of fluids from the reservoir to the processing facilities. Once these systems are brought into production, the ability to ensure optimal flow is critical to maximizing economic potential. From complex individual wells to vast production networks, the PIPESIM steady-state multiphase flow simulator enables production optimization over the complete lifecycle.
For over 30 years, the PIPESIM simulator has been continuously improved by incorporating not only the latest science in the three core areas of flow modeling—multiphase flow, heat transfer, and fluid behavior—but also the latest innovations in computing, and oil and gas industry technologies. The simulator includes advanced three-phase mechanistic models, enhancements to 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 on the GIS canvas or generated automatically using a GIS shape file. The interactive graphical wellbore enables rapid well model building and analysis. Faster simulation runtime has also been achieved for all modeling though the implementation of a new parallel network solver to spread the computational load across all processors.
The PIPESIM simulator offers the industry’s most comprehensive steady-state flow assurance workflows for front-end system design and production operations. The flow assurance capabilities of the simulator enable engineers to ensure safe and effective fluid transport—from sizing of facilities, pipelines, and lift systems, to ensuring effective liquids and solids management, to well and pipeline integrity. In addition, where dynamic analysis is needed to add further insight, the PIPESIM-to-OLGA converter tool enables rapid conversion of models. Shared heat transfer, multiphase flow, and fluid behavior methodologies ensure data quality and consistency between the steady-state and transient analyses.
New Python Toolkit environment
The previous Python Toolkit environment from Enthought has been replaced with a new Python distribution manager from Anaconda. A new script editor VSCodium has also been added. Various new PIPESIM steady-state multiphase flow simulator functionalities are now supported, such as rate constraints in network simulation and sensitivity in NODAL analysis task
Corrosion Model from TPA
A corrosion model from Trusted Pipeline Advisor has been added. This corrosion model is consistent with the NACE-ICDE standards and accounts for various new parameters such as regional stagnant water accumulations, bacteria or oxygen ingress, pre-existing corrosion damage, and evidence of black powder or debris
Multiflash version 7.1
Multiflash is an advanced fluid characterization software from KBC. In PIPESIM 2021.1, Multiflash 7.1 is added and will be downloaded automatically. You may refer to KBC website for more details. Multiflash license is sold separately.
A new option ‘Vogel water cut correction’ is added with ‘Use Vogel below bubble point’ option. This new option adjusts the IPR curve below bubble point based on water fraction. For higher water cut values, the curve tends to become more linear, and the effect of free gas is reduced.
GL Multi-pointing in NODAL Analysis
Gas lift multi-pointing is a non-desirable condition that can be modeled using gas lift diagnostics task. Now the PIPESM simulator can predict this condition in NODAL analysis and data comparison tasks. The valve status, open, close, or throttling is also available when the multi-pointing option is enabled.
Heat Transfer in wells
In PIPESIM 2021.1, you can let PIPESIM calculate the heat transfer coefficient for you using Ramey model, which takes into consideration geothermal conductivity as well as tubing, casing, and annulus material properties.
