Advanced transient multiphase flow simulator

LedaFlow is based on models that are closer to the actual physics of multiphase flow and provides the step change in accuracy and detail needed for longer tiebacks, deeper water and harsher environments. More modelling details can be found in the product sheet. 

LedaFlow Engineering 1D

LedaFlow Engineering 1D is a standalone engineering tool for transient multiphase flow simulation studies of oil, water and gas in wells and pipelines. It is a complete simulator used by Flow Assurance, Process, Production and Reservoir Engineers through the project life cycle to address gas/liquid, thermal, solid and integrity challenges.

The ability to simulate transient or time dependent behaviour means that the operability of the production system can be better understood to ensure a successful design and to maximise production from existing operations.

LedaFlow Point Model

The LedaFlow Point Model is the steady-state plug-in solution for a single location in a well or flowline. This mechanistic model is used to provide initial conditions for transient multiphase flow modelling and make it available to third parties including their steady-state simulation software. 

The LedaFlow Point Model is currently available in the following steady-state simulators

  • Synergi from DNV-GL
  • Maximus from KBC
  • Prosper and GAP from Petroleum Experts
  • Pipesim from Schlumberger
  • VMGSim from Virtual Materials Group
  • Wellflo and Reo from Weatherford

Application Areas

Research and Development

LedaFlow Technologies DA (LTDA) was established to represent a partnership between ConocoPhillips, KONGSBERG, SINTEF and Total funding and supporting all LedaFlow core physics research and development activities. KONGSBERG has exclusive commercialization rights for LedaFlow across the world.

LedaFlow Validation

Access to experimental/field data is key to model improvements and key to building a tool accurate enough for design purposes. To support the development of LedaFlow, extensive campaigns have been carried out in the industrial-scale Multiphase Flow Laboratory at SINTEF in Trondheim, Norway to provide new high-quality data.

This comes in addition to the more than 12,000 data points already available through the TILDA database (the database of test data acquired at SINTEF’s Multiphase Flow Laboratory). 

Over the years since commercialization, the development of LedaFlow has benefited from close collaboration with its industrial partners through a JIP based forum, LedaFlow Improvements in Flow Technology (LIFT) JIP.
