Laboratory

Petrolab central operations are based out of the main base in Adelaide, Australia from which we provide services throughout Oceania and South East Asia. Further to this, Petrolab has in the past operated globally through fully-equipped satellite laboratories in Malaysia, Venezuela and Bolivia. From our laboratories, we have the capabilities to carry out complete reservoir fluid studies, performed on all types of reservoir fluids from dry gases and gas condensates, through volatile oils to ultra heavy oils. Our analyses include:

  • All PVT experiments at reservoir conditions
  • Compositional analyses by chromatography and high temperature distillation
  • Enhanced Oil Recovery and Miscibility Experiments such as slim tube displacements, MMP by Rising Bubble Apparatus and solubility - swelling tests
  • Solid deposition experiments include the onset of asphaltene deposition and wax appearance temperature at reservoir conditions
  • Furthermore, we can design experiments to cater for each client's specific needs

For more information, or should you have any questions please don't hesitate in contacting us.


Petrolab's core speciality is PVT Analyses; on all types of reservoir fluids performed either in a main or customized mobile laboratory. Services are performed on pressurised reservoir fluid samples collected using Conventional Slickline, Wireline Bottom Hole or Recombined Separator Samples.

Common tests performed:

  • Differential Vaporisation (DV, also known as Differential Liberation DL)
  • Constant Volume Depletion (CVD) of gas condensates and oils
  • Constant Mass Expansion Study (known as CMS, CCE or CME)
  • Separator Tests
  • Viscosity-Pressure Relations

EOR Experiments include:

  • Slim Tube Tests
  • MMP by Rising Bubble Apparatus
  • Solubility and Swelling Tests

Amongst other physical PVT properties of reservoir fluids, these tests determine the following:

  • Saturation Pressure
  • Gas Liquid Ratios
  • Formation Volume Factor
  • Gas and Liquid Compressibility
  • Gas Dew Points
  • Viscosity and Density (from single phase to stock tank conditions)
  • Single and Multi Stage Separator Tests

PVT Equipment:

  • Special large cells (Sloane type) for lean Gas Condensate studies
  • Ruska type three window cells for gas condensates or volatile oil
  • Ruska type blind cells for black oil of up to 20,000 psig working pressure and 350°F

Petrolab offers accurate determination of Molar Compositional Gas Analyses by Chromatography up to C20+ including N2, H2S and CO2, GPM Content, Heating Value, Wobbe Index, Specific Gravity, Molecular Weight and Pseudo-Critical Properties.

Other services include:

  • Trace contaminants (metals, Hg, H2S, RSH, COS, etc.) in gas streams
  • Determination of molar fractions of other naturally occurring components such as He, H2, O2 and BTEX
  • Added tracers in gas injection projects
  • Dräger tube tests
  • Hydrocarbon and water dew points

Reported in the preliminary data stage used for the evaluation of PVT analysis requirements, Petrolab offers expert compositional, produced GOR, and fluid properties otherwise known as a "flash" analysis.

Other services include:

  • Molar Compositional Analyses of pressurised Separator and Bottom Hole Liquids extend to C35+ by Chromatography
  • High Temperature Vacuum Distillation to C20+ with measured molecular weight and densities of all cuts
  • PONA analysis on light ends (all components and their isomers to C12)
  • Wax and Asphaltene content
  • Pour and Cloud Point (on live crude)
  • Kinematic Viscosity and downstream Stock Oil Analyses characterization
