About Multiflash 7.2

Following the release of version 7.1, Multiflash 7.2 aims at the consolidation and refinement of functionalities introduced in 7.0 and 7.1 and at the introduction of new tools and functionalities to enhance and simplify the workflows of production and flow assurance engineers.

Version 7.2 marks also the first fundamental step on the development path towards the new generation of Multiflash with cloud-based deployment capabilities and web access. Multiflash remains at the forefront of the digitalisation wave that is investing the entire energy and chemical sector.

In parallel to that, we continue with the extension of the coverage of the new threadsafe DLL, to include also the asphaltene model and PC-SAFT and the completion of the missing high accuracy equations from the CSMA model.

A large portion of the development activities was dedicated to modelling accuracy. We focussed in particular on the Mercury model, within an R&D collaboration with Heriot Watt University and INPEX and co-funded by Oil and gas innovation centre.

We also looked again at the accuracy of predictions of our models for CO2-dominated systems, setting the ground work for the next green revolution of the industry, with decarbonisation, CCUS and hydrogen production and transport.

Summary of main themes

    Model Real Fluids – With its unique range of accurate and consistent thermodynamic and physical properties models, Multiflash allows predicting with great accuracy, the phase behaviour and transport properties of complex and highly non-ideal fluid mixtures, exhibiting the coexistence of several liquid, solid and gas phases for applications in upstream oil and gas production and transport (reservoir fluids, oils, condensates, natural gases, CO2, steam, high water cuts, alcohols, glycols etc.), petrochemicals (polymer and co-polymer blends), chemicals (acids, refrigerants) etc.

    Maximise Production – With its highly reliable and advanced models for gas hydrates and hydrates inhibition, wax, asphaltene, solid scales and mercury, Multiflash is the standard PVT and physical properties package in flow assurance. Multiflash allows modelling truly multi-phase systems, exhibiting the coexistence of several fluid and solid phases, providing an integrated and reliable solution for production optimisation and to forecast and handle potential flow assurance or equipment availability issues.

    Optimise Work Processes – Already embedded in leading flow assurance, production and process engineering software tools and with its advanced connectivity, Multiflash allows drastic increases of the effectiveness and efficiency of the engineering process, eliminating potential sources or errors due to the use of inconsistent fluid properties throughout the various steps of design and project execution. Multiflash provides engineers with a fully integrated workflow to accurately evaluate the physical and transport properties of reservoir fluids, perform point checks to avoid potential issues, rapidly assess options and compare the effect of design strategies and engineering solutions.

Specific highlights for this release

    Architectural changes and interfaces

        A brand new Restful API is available for cloud applications of Multiflash and will be commercialised shortly as part of KBC\’s cloud offering

        The new generation of CAPE-OPEN interface COBIA is now supported, which overcomes the limitation of current interface based on COM

        The thread-safe API (described in the C/C++ Interface manual) has been extended with new models and capability to create fluids in a thread-safe way

        New functions have been added to calculate Critical points, and to calculate properties of phases without flashing

        DIPPR 2019 is now available in standard and supporters versions

    Models\’ accuracy improvements

        Full re-implementation and re-parameterisation of the Asphaltene model with thread-safe capability as part of the Multiflash-MT project

        Binary interaction coefficients between CO2 and hydrocarbon has been updated, with accuracy improvements for heavier hydrocarbons

        Binary interaction coefficients for Mercury model have been updated using the very latest experimental data

        Extended components supported by CSMA model and updated refrigerants R14, R114, RC318 and R125 with the latest equations

        Corrected BIPs for EOS-CG

        N2O supported as hydrates former

        Pedersen viscosity model and the Pedersen Heavy oils model are now unified in a single model. Internally Multiflash switches between the two depending on the reduced temperature of the fluid

    User experience and workflows

        Extensions of mud cleaning functionality to support numerical cleaning of reservoir fluids also in absence of estimated mud contamination (subtraction) and/or mud composition (skimming)

        Extension of the common pseudos characterisation method to allow the addition of new fluids to a set of fluid originally characterised with common petroleum fractions

        In Cubic EoS model selection, the special options for Vapor pressure fitting and Volume shift can be selected individually

        Even if a component is searched and added via CAS number, in the components list it will appear with its default name

        The behaviour of the models setting dialog has been improved to give more flexibility when only adding/removing phases or modifying physical properties models without changing the EOS
