Start with the system boundary you must model
If your core decisions depend on multiphase behavior inside the reservoir, choose Eclipse from Schlumberger for compositional field-scale simulation. If your decisions depend on connecting seismic interpretation to layered earth models and field development design, choose Petrel from Schlumberger for geologic modeling and integrated petrophysics with well planning.
Match the simulation type to your design-time questions
For production system performance across wells, flowlines, and pipelines, choose PIPESIM from Schlumberger because it supports dynamic multiphase flow with pipe hydraulics and thermodynamics for steady and transient scenarios. For flow assurance and transient thermal-hydraulics risks like slugging, choose OLGA from Schlumberger because it is built around rigorous transient multiphase pipeline and riser physics with thermal coupling.
Select the software that generates the engineering deliverables you actually ship
If you need governed 3D piping design and isometrics for construction documentation, choose Autodesk Plant 3D or AVEVA E3D for intelligent routing and 3D-to-isometric fabrication outputs. If your work package is offshore structural design with repeatable analysis, choose SACS from Bentley for finite element load case handling for jacket, topside, and pipeline-related structures.
