Pore-scale Investigations of Steam Injection

​The 10×15 cm and 5×5 cm 2D visual sandpack models were prepared and placed into a transparent vacuum chamber to prevent heat loss. The processes were recorded with a high-speed camera to obtain visual data at the pore scale. This process represents the lateral spreading of the steam chamber during steam-assisted gravity drainage (SAGD) for heavy-oil recovery.

Micro-Model Visualization Setup

This setup is used to study the interactions of different phases during enhanced oil recovery techniques such as solvent injection or alternative solvent and water injection.  In such EOR techniques, several phases exist including matrix grain, solvent, oil and water. Therefore the visualization process requires use of UV light with application of appropriate (water-base or oil-base) tracers. With this method, it is possible to visualize more than three phases in the model.

The micro-model visualization system is composed of a high speed camera mounted on a microscope, a UV light source, syringe pump and the micro-model. The maximum magnification of this system is 2600X. Therefore, with this setup it is possible to visually observe any microscopic change in the residual oil.
