Our Reservoir Fluid PVT Analysis System is complete of one set of PVT instrument (PVT 500/1500 full visual 500cc) and some ancillary equipment, as gasmeter, HP pressure sample cylinders, viscometer, etc.

It is able to analysis different GOR reservoir fluid as crude oil, volatile oil, gas condensate and gas under high pressure and temperature conditions. This system can process the comprehensive evaluation for oil and gas reservoirs.

The PVT 500/1500 with accessories is designed to perform:

• A complete PVT study on oil and volatile oil GOR < 800 Sm3/m3 conducted in four
  stages:
  • Constant Composition Expansion (i.e. CCE) at constant temperature,
  • Differential vaporisation at constant temperature,
  • Separation tests (several stages at different temperatures)
  • Viscosity measurement
• A complete PVT study on gas condensate with high GOR conducted in two stages:
  • Constant mass depletion (i.e. CMD)
  • Constant volume depletion (i.e. CVD),
• A recombination of separator oil or condensate and separator gas under reservoir conditions
• A analysis of viscosity, density, composition (Accessories in option)
• Z factor determination
• Dew point determination by IR
• GOR
