Preview the Possibilities Using Digital Twins

In diverse applications, Multiphase Cloud® simulation platform helps energy companies comply with stricter regulations and face market pressures — while minimizing operating and maintenance (O&M) costs. By replicating different types of complex multiphase flows, we can help your engineering and O&M teams address the specialized requirements for optimal fluid dynamics in pipelines to enhance hydrocarbon production and provide uninterrupted, safe operation of oil and gas gathering systems.

Multiphase Cloud® is a simulation platform that contains the broad, physical modeling capabilities needed to model, visualize, and analyze simultaneous flow of all types of fluids and solids (gas, liquid hydrocarbons, water, sand, proppant, sludge, black powder, elemental sulfur, drilling mud, and control fluids) encountered in oil and gas production operations.

Areas of Applications


  • Optimum diameter to minimize the costs of pigging and chemical inhibition throughout the life of the pipeline

  • Improved design of process lines

Life Extension 

  • Analysis of material degradation

  • Assessment of overall risk picture

  • Development of mitigation measures


  • What if analysis

  • Total volumes of oil, water, and solids or sludge in the pipeline

  • Onset of flow instability and its mitigation strategies


  • Indirect inspection

  • Internal corrosion monitoring

  • Predictive O&M

  • Root cause analysis (RCA)

Through virtual modeling that makes the pipeline “transparent”, you can identify threats and effectively manage risk in an industry fraught with uncertainties.

Indirect Inspection of Pipelines

We go beyond regulations and industry standards in the assessment of internal corrosion in all type of pipelines. Up to 36 flow parameters are predicted in the Indirect Inspection step (Step 2) of the NACE ICDA methodology. These results are compared to all available field data, including corrosion coupons installation and retrieval reports.

With the High-Fidelity Simulation and Exposure Duration Determination capabilities of Multiphase Cloud, engineers can reach an unparalleled level of accuracy in determining the internal corrosion risk using a physics-based approach.

Technical Specifications

Flow Model

12 combinations of 2-phase, 3-phase, and 4-phase flows of produced fluids and solids or sludge can be simulated. Up to 36 flow parameters are predicted at each location along the pipeline. 5 gas-liquid flow patterns and 5 oil-water flow patterns in the liquid phase are determined. Two aqueous phases can be modeled: free water and emulsified water to simulate an emulsion breaking process in crude oil not related to its velocity.

Pipeline Profile and Discretization

Elastic deformations of the pipeline in the longitudinal direction are taken into account. Models of elbows, with the flow direction change in the vertical plane, can be constructed considering the design code used for their fabrication. A high-resolution discretization of entire pipeline is used in combination with adaptive grid refinement employed to simulate flow direction changes.

Solids and Sludge Transport Models

Proprietary models describe the transport of solids and sludge along the pipeline. These were developed and validated using field data for a wide range of flow conditions and applications.

Fluid and Solids Properties

A black-oil PVT model or an equation-of-state model is used to predict properties of the produced fluids. Solids properties are the properties of solid particles measured in a laboratory. Sludge properties are its rheological properties determined in a laboratory.

3D Visualization

A Digital Twin of a pipeline - whether planned or already built - will show how produced fluids and solids flow along that pipeline during its lifetime.
