Multiflash Overview

About Multiflash™ 6

With the release of version 6 and the inclusion of major enhancements in the area of PVT modelling and tuning of EOS to PVT experiments, we finally close one of the gaps that historically limited the penetration of Multiflash in the most upstream segments of the oil and gas value chain, and we allow an effective bridging between the subsurface fluid modellers, to the production and flow assurance or process engineers. After the incorporation of Multiflash 4.3 as the standard PVT package in Olga and being already embedded or connected to major flow assurance, production and process engineering tools, Multiflash was, in fact, already a reference physical properties package for the engineering community. However, the lack of PVT modelling and model tuning capabilities surely limited its popularity amongst the reservoir and petroleum chemists and engineers who cover the first and therefore crucial, segment in the engineering process. For the accuracy of its models, Multiflash was already considered as the standard PVT and physical properties package in flow assurance. With these enhancements we now provide engineers with a robust and integrated tool, allowing them to use the same coherent and consistent thermodynamics to model the fluid across the entire value chain, from the reservoir to the refinery.

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.
