What is HydraFLASH?
HydraFLASH is Hydrafact’s thermodynamic prediction software designed to calculate the phase equilibria and physical properties of petroleum reservoir fluids (including: oil, gas, water, salt, alcohols, glycols, hydrates & ice) over a wide range of pressure and temperature conditions.
It was created through numerous industry & government-sponsored R&D projects by the Heriot-Watt Hydrate and Reservoir Fluids research groups and Hydrafact Limited over many years (since 1987) and has been developed by a variety of experts from fields such as Chemical/Petroleum Engineering, Flow Assurance Engineering and Computer Science.
In the past 10 years, we have added a strong database on PVT and Flow Assurance of Hydrocarbon and CO2, and H2 systems with around 15,000 data points.

Why use HydraFLASH?
Comprehensive experimental facilities have allowed us to tune and validate the model using a vast, largely unpublished in-house flow assurance and PVT equilibria database.
As a result, HydraFLASH is the most accurate model available for predictions involving real-world production systems.
Watch Professor Bahman Tohidi Explain HydraFLASH's Advantages and Capabilities:
The Model
Equation of State & Mixing Rules
A combination of equations of state (EoS) and appropriately selected mixing rules provide a powerful tool capable of modelling complicated multiphase, multicomponent systems. The SRK and PR EoS are commonly used for modelling in the oil and gas industry and are included in HydraFLASH in addition to the Peneloux density correction and different mixing rules.
HydraFLASH incorporates the Valderrama-Patel-Teja (VPT) EoS with non-density dependent mixing rules (NDD) used in modelling fluid phases. The combination has proved to be very effective for modelling systems with polar as well as non-polar components. The CPA (Cubic Plus Association) is a new approach that has a number of advantages when modelling fluid phase equilibria for systems containing components which can form hydrogen bonds (e.g. water, methanol, ethanol, MEG).
Hydrate Phase Modelling
The hydrate phase is modelled by the solid solution theory of Van der Waals and Platteeuw. The Kihara model for spherical molecules is applied in order to calculate the potential function for compounds forming the hydrate phases.
Electrolyte Solution Modelling
Electrolytes are modelled by an improved Aasberg-Petersen model. The model can be used over a wide range of temperature and salt concentrations, and is capable of handling mixed electrolyte solutions.
Technical Specifications
Continuously tested for real process scenarios with validation against in-house and literature experimental data.

Inhibitors
When developing a hydrate remediation strategy an accurate knowledge of hydrate phase equilibrium in the presence of inhibitors is crucial to ensure hydrate formation is avoided for a system.
HydraFLASH can be used to model water-hydrocarbon systems in the presence of organic inhibitors. This can be with or without the presence of gas hydrates over a range of temperature and pressure conditions. The software also includes all of the common thermodynamic inhibitors available that can be used for modelling.
*Offer some degree of inhibition, but can also form hydrates under certain conditions.
Available Inhibitors
- Methanol
- Mono-ethylene glycol (MEG)
- Di-ethylene glycol (DEG)
- Tri-ethylene glycol (TEG)
- Propylene glycol (PG)
- Gycerol
- i-Propanol*
- n-Propanol*
- Ethanol*
Salts
In a production scenario the aqueous phase of a produced fluid will typically already contain salts from either well completion fluids or formation water and these salts have an inhibiting effect on hydrate formation. HydraFLASH can model these effects.
Available Salts
- NaCl
- KCl
- CaCl2
- Na2SO4
- NaF
- KBr
- MgCl2
- SrCl2
- BaCl2
- NaBr

Interfaces
Windows GUI
HydraFLASH is available as a newly enhanced and modern GUI. This allows systems to be set up and calculations to be carried out quickly and easily. It provides an intuitive user interface with access to all HydraFLASH facilities with outputs as text files, graphics or Excel worksheets.
Microsoft .NET Resource Library (DLL)
HydraFLASH is available as a Windows .NET dll which runs under any 32 bit / 64 bit version of Windows. This can be called from any application written in a language that provides support for . NET dlls. As well as the whole application, individual HydraFLASH modules are also available.
Calculation options
The HydraFLASH hydrate model can accurately predict the formation of hydrates and the inhibition effect and distribution of hydrate inhibitors in oil and gas systems. If the water contains salts, the influence of these salts on the hydrate formation conditions will also be taken into account.
HydraFLASH can accurately predict:
- The most stable type of hydrate formation structure ( I, II and H)
- If hydrates will form at a given temperature and pressure
- The minimum inhibitor injection rate to prevent hydrates as a function of the water cut
- The distribution of inhibitor in different phases
- Maximum water content permissible before hydrate formation
- The hydrate formation and inhibition effect of ethanol and i-propanol, n-propanol
The PT flash option automatically provides the number of existing phases and amounts of each phase including hydrocarbon, aqueous phases, solid salt phases, hydrates and ice. HydraFLASH can also perform Dew point, Bubble point and Phase Envelope calculations amongst many other features and functions.
HydraFLASH can accurately predict:
- Phase amounts, molecular weight and compositions
- Density, molar volume, fugacity and Z-factor
- Joule-Thomson coefficient and speed of sound
- Enthalpy, entropy, Cp and Cv
- Viscosity, thermal conductivity, and interfacial tension (IFT)
- Hydrate stability warning
