Schlumberger Symmetry 2022.1

Schlumberger Symmetry 2022.1

Symmetry process software platform captures all aspects of your models, from reservoir to product distribution. The Symmetry process software 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. This approach enables companies to optimize processes in upstream, midstream, and downstream sectors, maximizing profits and minimizing capex.


v2021.1 (March 2021 – Symmetry Release)



+ Added 43 new fluids from REFPROP Release 10.0 to VMGREFPROP property packages
