NANOPARTICLE TRANSPORT
• Problem in using nanoparticles downhole is understanding and controlling nanoparticle transport through porous media
• Nanoparticles need to be delivered to the required location
• Nanoparticles need to adsorb/desorb to/from surfaces of they are to change surface properties e.g. wettability – effect of flow?
![Page 11: Deploying Nanotechnology in Oil and Gas Operations: Pore ... · NANOTECHNOLOGY IN OIL AND GAS •Rapidly growing interest in nanotechnology in oil and gas industry, as highlighted](https://reader033.fdocuments.us/reader033/viewer/2022042916/5f55aa73cf4bed7a9d4408b1/html5/thumbnails/11.jpg)
• Experimental corefloods can give some idea of macroscopic effects and changes in behavior, but give no indication of pore-level coverage or mechanisms
NANOPARTICLE TRANSPORT
Inject e.g.
nanoparticle
suspension
Monitor
effluent
Rock core sample
What is the
distribution and
coverage inside?

CONCLUSIONS
• CFD offers the opportunity to explore nanoparticle penetration and distribution within pore networks
• To begin, simple geometries considered to explore local effects
• Through variations in the bulk concentration at the surface, fluid flow has been shown to influence the local adsorption of nanoparticles
• However, flow is not explicitly included in the material balance (adsorption-desorption) equation
