Upgrading of Heavy Oil and Bitumen

Electromagnetic (EM) and acoustic (US) waves are innovative methods designed to address the challenges of producing and transporting heavy oil and bitumen. These techniques leverage electroacoustic energy to alter the properties of oil, enhancing its mobility and reducing extraction costs. The application of EM and acoustic waves disrupts heavy oil's molecular structure, leading to viscosity reduction and improved flow characteristics. This approach is particularly valuable for recovering heavy oil reserves, which represent a significant yet underutilized energy resource globally.  

Our research group studies extensively the application of electroacoustic technologies for heavy oil recovery. We have studied the effects of EM and US waves on viscosity reduction, which facilitates enhanced flow in heavy oil reservoirs. Additionally, our work on acoustic stimulation focuses on mobilizing trapped oil by disrupting capillary forces and promoting fluid displacement. Experimental capabilities, including high-resolution CT scanning, acoustic wave generators, and core flooding setups, have allowed us to validate these techniques under realistic reservoir conditions. Recent projects include investigating the interaction of EM and acoustic waves with nanoparticle-assisted recovery processes and developing acoustic wave strategies to minimize formation damage during production.  

Our findings indicate that electroacoustic recovery and upgrading techniques can significantly enhance the efficiency of heavy oil production. These methods not only improve recovery rates but also have potential applications in upgrading oil properties in situ.
