Gas CondOil - Process Simulation Software for Natural Gas and Oil Engineering


Functional Overview:

The thermodynamic simulation of phase behavior in systems:

  • Vapor-Liquid
  • Vapor-Liquid-Liquid
  • Vapor-Liquid-Liquid-Solid (free salts)

The technological calculations are provided for following mixtures:

  • Gas
  • Condensate
  • Oil
  • Mineralized water
  • Methanol
  • Glycols (EG, DEG, TEG)

The following properties of gases and liquids are calculated:

  • Enthalpy
  • Entropy
  • Thermal capacity
  • Density
  • Viscosity
  • Thermal conductivity
  • Surface tension
  • PVT-Properties of reservoir oil
  • etc.
Simulation:

of the reservoir condensate and oil composition and properties taking into account of oil and condensate distillation data (recombination procedure).

of the phase, hydraulic- and temperature behavior of streams in pipelines (horizontal, inclined, with variable level) transporting following single- and multiphase mediums:

  • Gas
  • Oil
  • Gas-water-oil
  • Gas-water-condensate
  • Unstable oil
  • Unstable condensate
  • etc.

The technological calculations are provided for following processes :

  • Two- and three-phase separation
  • Throttling
  • Mixing
  • Ejection
  • Expanding
  • Compression
  • Heat exchange
  • Distillation
  • Absorption

In particular following industrial systems are modeling:

  • Field transportation and gathering of natural gas and oil
  • Field-separation, glycol-absorption and oil-absorption processes
  • Reconcentration of glycols and methanol
  • Fractional distillation and stabilization of condensate and oil
  • Liquefaction of natural gas
  • etc.

The thermodynamic calculations are provided for following values:

  • Hydrate-forming conditions and inhibitors expenditure
  • Vapor pressure
  • Reid vapor pressure
  • Water and hydrocarbon dew points
  • etc.

There are possibility of adaptation of GasCondOil-program to field and laboratory study data:

  • Stock tank oil or condensate density and viscosity
  • Saturated pressure of oil
  • Isothermic compressibility factor of reservoir oil
