Petrophysical and Fluid Property Determination

Physical and numerical modelling, as well as analyzing laboratory experiments, requires petrophysical and fluid property determination.  

laboratory tests:

  • Pressure, Volume, Temperature (PVT) Analysis and Fluid Characterization
  • Asphaltene Precipitation Modelling 
  • Pseudorelative Permeability Determinations

These tests can be conducted in the ranges of: 200 – 23,000 kPa and 5 – 200 C.

We can perform special PVT analysis to determine oil density, viscosity and vapour-liquid equilibrium (VLE) relationships as a function of solvent concentration, pressure and temperature. A minimum of three, but usually five operating conditions are gathered to characterize the fluids with a commercial simulator.

In conjunction with special PVT analysis, SRC offers laboratory studies to determine asphaltene precipitation tendencies. Asphaltene precipitation frequently occurs during SVX and TSVX processes. The type and extent of the precipitation is dependent on the particular solvent–oil system and the pressure and temperature conditions.

Two and three phase pseudorelative permeability curves can be determined using core displacement tests with various solvent diluted oils at elevated temperature and pressure conditions. These curve sets reflect the shift in end-point saturations due to reduced heavy oil or oil sands viscosities.
