ISUT: A Breakthrough in Transporting Ultra-Dispersed Catalysts for Sustainable Heavy Oil Upgrading

The quest for sustainable methods to unlock heavy oil and bitumen resources has led to the development of NanosTech’s innovative ISUT technology (In Situ Upgrading Technology). This groundbreaking approach utilizes ultra-dispersed catalyst particles to catalytically upgrade heavy oil during thermal recovery processes. Overcoming the challenge of effectively transporting these catalyst particles through porous rock formations is a critical step towards achieving environmentally friendly heavy oil upgrading.

Experimental Study on Transporting Catalyst Particles (NanosTech’s NanoCatalyst)

Researchers from the Department of Chemical and Petroleum Engineering at the University of Calgary conducted a comprehensive experimental study to investigate the feasibility of transporting ultra-dispersed catalyst particles through sand packs. These sand packs simulate the porous rock formations found in oil reservoirs.

Key Findings

1. Successful Propagation of Ultra-Dispersed Catalyst Suspension — The experimental results demonstrated that it is indeed possible to propagate ultra-dispersed catalyst suspensions through sand beds. This breakthrough finding is a significant step forward in realizing the potential of in situ upgrading of heavy oil using nanosized catalysts.

2. Minimal Permeability Damage — The research revealed that the retention of nanoparticles at low concentrations had negligible effects on pressure drop and caused no significant permeability damage. This means the transport of ultra-dispersed catalyst particles is unlikely to impair the reservoir’s productivity.

3. Uniform Distribution of Retained Particles — In experiments conducted without connate water, the retained catalyst particles exhibited a more uniform distribution along the core length, suggesting predictable and controlled deposition.

4. Stable and Long-Term Catalyst Placement — The deposition of catalyst particles within the sand pack was found to be irreversible. Once deposited, they remained firmly in place and could not be easily remobilized by reverse flow of the suspending medium.

Implications and Future Prospects

The positive findings from this experimental study provide strong support for NanosTech’s ISUT as a highly promising solution for sustainable heavy oil upgrading. By enabling the efficient transport of ultra-dispersed catalyst particles through porous media, this technology offers a viable pathway to unlock vast heavy oil deposits worldwide.
