HydraFLASH™

PVT and Flow Assurance prediction software

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.

  • • Constant Volume Depletion (CVD)
  • • Separator Test
  • • Viscosity

Fluid Characterisation

The fluid characterisation module in HydraFLASH provides a variety of options to prepare mixtures for different computational purposes:

  • • Plus-Fraction Splitting
  • • Oil and Gas Recombination
  • • Oil-Base Mud Removal
  • • Mixing Fluids
  • • Wax Characterisation and PNA Distribution
  • • Asphaltene Characterisation and SARA Analysis

EOS Calibration

The meta-heuristic global optimization algorithm available in HydraFLASH facilitates matching EOS predictions and laboratory PVT data.

These options are available in the EOS calibration module:

  • • Setting weight factors for experimental data
  • • Tuning thermodynamic properties of heavy components
  • • Tuning volume shift parameters to correct density predictions
  • • Tuning viscosity model parameters to match viscosity data

Hydrate Formation
Modelling

The HydraFLASH hydrate module, using the solid solution theory of Van-Der-Waals & Platteeuw and optimized Kihara parameters for spherical molecules, can accurately predict the formation of hydrates and the inhibition effect of inhibitors in oil and gas systems, including the impact of salts on hydrate formation conditions.

HydraFLASH predicts:

  • • The phase determining hydrate structure (I, II, and H)
  • • Hydrate amount flash calculation
  • • Shift in hydrate dissociation curve caused by inhibitors
  • • The minimum inhibitor injection rate to prevent hydration
  • • Maximum water content permissible before hydrate formation
  • • Melting time of hydrate at a given temperature gradient

Asphaltene Precipitation
Modelling

The asphaltene modelling module in HydraFLASH implements comprehensive fluid characterisation required by PC-SAFT equations of state to predict asphaltene onset pressures and precipitation amounts.

The asphaltene model tuning module in HydraFLASH uses the following experimental data:

  • • Saturation points
  • • Upper and lower onset pressures
  • • Titration data

Wax Appearance
Prediction

The wax modelling module in HydraFLASH predicts wax appearance temperature and wax content for mixtures containing paraffin as the main contributors to wax formation.

Parameters of the wax model can be adjusted with respect to both wax appearance temperature data and wax content data.

The comprehensive PVT database in HydraFLASH contains more than 15,000 data points on water content, solubility, and hydrate dissociation points for a variety of components including light gases, inhibitors, and brines.

Filtering the data can be done based on the publication year, article title, and article authors.

Software support and maintenance services are our top priority, ensuring the productive use of HydraFLASH software within different oil and gas engineering fields.

A group of experts including chemical/petroleum engineers, flow assurance engineers, and software developers are willing to help you get the most out of HydraFLASH software.

TECHNICAL SPECIFICATIONS

Continuously tested for real process scenarios with validation against in-house and literature experimental data.

Calculation
Options

For HYDRATE

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

For PVT

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)
