3-D Scaled Physical Modelling of Thermal-Solvent Vapour Extraction (TSVX) Processes

Hybrid thermal-solvent based enhanced oil recovery (EOR) processes are investigated at SRC using one of the largest 3-D physical models known to exist. These studies are intended to provide a clearer understanding of rate controlling mechanisms for the purpose of accelerating the development, deployment and optimization of these processes for the heavy oil and oil sands industries.

History matching of the experimental runs using advanced algorithms provides for the calibration of numerical simulators predicting field-scale performance. Coupled with comprehensive economic models, both the technical and the economic viability can be determined for a particular TSVX process.

Our services include:

• Physical Modelling
• Numerical Modelling
• Petrophysical and Fluid Property Determination

The physical model apparatus consists of the overburden pressure vessel (OBV) system rated for 10.5 MPa working pressure at 10 to 250 C. The OBV can operate in both the horizontal and vertical positions, and can accommodate large physical models with a vertical reservoir thickness of up to 2.5 metres, pore volumes between 80 and 180 litres that contain either vertical or horizontal wells and any type of porous media, and can accommodate the injection of any combination of liquids and/or gases.

We offer analytical tests and property determinations required for 3-D physical and numerical modelling of TSVX processes:

• Equation of state (EOS) determinations to generate steam-solvent-temperature diagrams
• Special pressure, volume, temperature (PVT) analysis to determine oil viscosity, density and vapour-liquid equilibrium (VLE) at up to 200 C
