Comprehensive Surface Network Modelling
Model complex production systems including wells, pipes, separators, chokes, pumps and compressors, enabling accurate system-wide analysis.
Network Designer
Surface Network & Integrated Asset Modelling
Model wells, pipelines and facilities in one integrated asset model – optimising production and flow assurance across the full field
Build and Optimise Surface Networks Across the Full Asset
tNavigator’s Network Designer is surface network modelling software that lets engineers design, analyse and optimise production systems across wells, pipelines and facilities. By bringing reservoirs, wells and surface infrastructure into a single model, it supports full-field optimisation and improved asset performance.
Optimise with Production Designer
Network Designer delivers a fully integrated asset modelling approach, combining subsurface and surface systems within one platform – helping engineers optimise production across the entire asset, identify bottlenecks and inefficiencies, and improve flow assurance and operational performance.
Integrated Asset Modelling
Combine reservoirs, wells and surface facilities in a unified model with synchronised visualisation and fully implicit system calculations.
Network Optimisation Tools
Improve operational efficiency by redistributing flows, removing bottlenecks and mitigating risks such as corrosion, erosion and hydrate formation.
Network Designer supports a wide range of production system workflows:
- Surface network modelling – design and simulate networks including wells, pipelines and facilities.
- Integrated asset modelling – combine reservoir, well and surface systems into a single model.
- Pressure and temperature analysis – evaluate system behaviour under different operating conditions.
- Steady-state and dynamic simulation – perform both steady-state calculations and fully coupled simulations.
- Flow assurance analysis – identify and mitigate issues such as hydrates, corrosion and erosion.
- Production optimisation – adjust network configurations to maximise efficiency and output.
- PVT and well integration – use fluid properties and well models to control system behaviour.
Network Designer is fully integrated within the tNavigator platform:
- Connect with reservoir simulation models for dynamic coupling.
- Integrate with Well Designer for accurate well performance and PVT Designer for fluid properties.
- Combine with Model Designer, Material Balance Analyser and external models into a single integrated project via Production Designer.
