Multiflash Overview

About Multiflash 7.0

Following the release of version 6.2, Multiflash 7.0 marks a major step in the path towards the progressive replacement of the Multiflash engine with the new generation thread-safe DLL. This huge architectural restructuring of the software carries significant functional and non-functional improvements and, most of all, will allow a more effective deployment of the Multiflash engine in computationally intensive applications that require strong parallelisation, with reduced memory footprint, stability of computation and high performance. Multiflash 7.0 includes the deployment of the new thread-safe implementation of a number of important and commonly used equations of state which now include the cubic equations of state and CPA, as well as the high accuracy EoS and models like GERG-2008, Span-Wagner, CSMA etc.. Upon completion all the models and EoS (equations of state) and models available in Multiflash will be re-implemented in the new thread-safe DLL, with additional variants and a complete re-parameterisation of the models, to increase accuracy and reliability. With the release of MF 7.0 we also extend our range of modelling capabilities, including two new EoS and our PVT modelling capabilities, by adding the possibility to simulate EOR PVT experiments. Finally, with MF 7.0, we make a start in the development of a fluid library aiming at simplifying the management of complex workflows and the sharing of information across project-teams as well as simplifying the handling of large collections of fluids and data.

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.
