3-D Scaled Physical Modelling of Solvent Vapour Extraction (SVX) Processes
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 industry.
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 SVX process.
Our services include:
The physical model apparatus consists of the overburden pressure vessel (OBV) system, rated for 10.5 MPa working pressure at 10 to 60 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 150 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 SVX processes:
• Equation of state (EOS) determinations to generate solvent vapour quality diagrams
• Special pressure, volume, temperature (PVT) analysis to determine oil viscosity, density and vapour-liquid equilibrium (VLE)
• Pseudorelative permeability determinations
