\HPROGRAM 'GOW'\h
'GOW' calculates physical properties of the following gases and
liquids:
a) Gases
- Natural gas
- Nitrogen
- Air
b) Liquids
- Oil
- Water
- Methanol/Water mixtures
- Monoethylene glycol/Water mixtures
- Diethylene glycol/Water mixtures
- Triethylene glycol/Water mixtures
Oil properties are calculated based on a black-oil model.
In fluid-property terms the black-oil model employs 2 pseudo-
components:
1) "OIL" defined as produced oil at stock tank conditions
2) "GAS" defined as produced separator gas
The basic assumption is that gas may dissolve in the oil
phase, but oil will not dissolve in the gas phase. For
mixtures of heavy oil and light components this is a
reasonable assumption, but is a misleading assumption for
mixtures of light and intermediate components.
The program is divided into 2 major sub-programs, one for gas
properties and one for liquid properties.
'GOW' will let you choose between SI-units (metric) or
Customary units.
The gas property routine calculates:
- Molecular weight
- Density
- Compressibility
- Gas formation volume factor
- Z-factor (gas deviation factor)
- Viscosity
- Thermal conductivity
- Specific heat
- Ideal isentropic coefficient, Cp/Cv
- Real isentropic coefficient, k
- Pseudo Critical properties
- Pseudo Reduced properties
The liquid property routine calculates:
- API gravity (for oil only)
- Density
- Compressibility
- Formation volume factor (oil and water only)
- Solution gas-liquid ratio (oil and water only)
- Bubble point pressure (oil only)
- Viscosity
- Thermal conductivity
- Surface tension
- Specific heat
- Pseudo Critical properties
- Pseudo Reduced properties
The MINIMUM EQUIPMENT CONFIGURATION required by 'GOW':
a) DOS version:
1) An IBM PC, XT, AT or compatible computer
2) 256 K or more of RAM memory
3) DOS 2.0 or later operating system
b) Windows version:
1) A computer with 80386 processor or better (486, Pentium)
2) 4 MB RAM memory
3) Windows 3.+
