In this context, nanotechnology derived imaging contrast agents, such as magnetic nanoparticles, have the potential to unveil long distance reservoir architecture , establishing fluid-flow trends, and identify reserve growth potential. The high magnetic susceptibilities of these particles compared to most reservoir rocks and fluids make them ideal potential magnetic contrast agents to mix with proppant and help to monitor the progress of hydraulic fracturing jobs downhole.
This project aims to the development of novel Magnetic Nano-Particles MNPs with controlled size, shape, and surface coating, acquiring long-term aqueous stability and long-distance transportability into the harsh oil reservoir environment.
Demonstrating The Benefits of Solid-State NMR to Non-Experts
MNPs will be flooded with water into oil reservoirs, and their flow paths will be tracked with logging Electromagnetic Methods magnetic permeability alteration maps , providing thus a novel methodology for 3D mapping of fracture architecture and fluids distribution in the Middle-East Carbonate Reservoirs.
