SLB Symmetry 2025.3

SLB is pleased to announce the availability of Symmetry 2025.3 process software platform. This platform offers a unique opportunity to model your process workflows in one environment, integrating pipelines, networks, and facilities models, while ensuring consistent thermodynamics and fluid characterization across the full system.


Flaresim software: share fluids across multiple cases
Flaresim flare systems design and analysis software’s new functionality makes it easier than ever to select and copy fluids from one case to another using a simple, streamlined workflow. This enhancement saves time and ensures consistency by transferring all fluid data, including original input values and calculated results, so everything stays aligned and audit-ready across cases. This functionality is available for fluids characterized using Flaresim software, Symmetry software, REFPROP, and WellTestAPI methods.


Investigate the impact of optimizer variables through sensitivity plots
A new sensitivity analysis feature has been added to the Optimizer as a dedicated tab, allowing users to investigate how individual manipulated variables affect the objective function and constraints. This enhancement helps identify which variables have the greatest impact, enabling more informed decisions around variable prioritization and constraint adjustments. To make the data easier to interpret, the feature includes a sensitivity plot that visually illustrates these relationships.


Improved results for CO2 mixtures with APRNG2
Improvements in Vapor-Liquid Equilibrium predictions (VLE) predictions for CO2 containing mixtures are now available with the APR for Natural Gas 2 thermodynamic model. Updates include refined binary interaction parameters for CO2 with SO2, O2, N2, CO and Ar, resulting in better alignment with experimental data. Additionally, enhanced ternary behavior of CO2/Ethanol/Water systems supports more accurate simulations for bioethanol-related applications.


Rate-based towers expanded capabilities
The rate-based tower now offers enhanced flexibility for configuring non-ideal stages, introducing a broader range of specification options. Draw streams on rate-based stages can be defined using either mole flow rates or draw-to-feed ratios. Similarly, energy inputs on rate-based stages can now be specified per fluid phase using direct duty values or duty-to-feed ratios. Additionally, the rate-based tower now supports the inclusion of pump-arounds and vapor slips, which can be configured using mole flow rates and a choice of duty, return temperature, or temperature difference.


Enhanced workflows for opening cases with the built-in PFD
Symmetry software provides a seamless workflow for opening cases when their PFD settings do not match the last saved PFD engine of the case. Upon opening a case, users are prompted to choose between Microsoft Visio® or the built-in PFD engine, enabling case specific customization. Enhanced workflows for the built-in PFD engine, allowing easier case opening and conversion from Microsoft Visio® to the built-in PFD, subject to feature compatibility. However, conversion from the built-in PFD back to Visio is not supported.



Symmetry process simulation software enables full life cycle modeling from conception to operation, providing better options to troubleshoot performance, create feed and startup studies, and fully optimize your system. It offers a comprehensive set of flare and relief system design tools, empowering users to verify the performance of entire safety systems. The platform is flexible enough to suit any application, analyzing standalone components or complete systems with various levels of detail, in steady state or dynamics. Symmetry provides a new approach to traditional oil pseudo-component characterization techniques. Its fluid characterization uses chemical family structures to enable accurate physical property estimation in blending, separation, and even reactive systems to be more accurately simulated, ensuring consistent thermodynamics and component tracking across the full system. The software also offers extensive options to provide openness.
