Abstract

The purpose of this idea is to provide high resolution, high accuracy 3D maps of sub-surface hydraulic fractures by using tuned magnetic nanoparticles. It is known that electro-magnetic response of magnetic nanoparticles can be "tuned" by simply varying the size of the particle. What differentiates this idea from other processes is the use of tuned magnetic nanoparticles for each stage of the well. Therefore, each stage will have its own magnetic fingerprint associated with it. By electro-magnetically logging the well after all stages are fractured, we can detect the electro-magnetic response of the particles that have been co-deposited with the proppant to generate maps of how the fractures are growing and how fractures from each stage are communicating with each other. The knowledge of the fracture behavior of each stage will ultimately provide key information to developing future fracturing jobs based on actual fracture geometry and orientation.

Description:     The electro-magnetic properties of magnetic nanoparticles are "tunable" based on the size of nanoparticle. That is to say, the electro-magnetic response of magnetic nanoparticles is size dependent. Hence, it is possible to generate a specific electro-magnetic signature from each sized particle. The idea is to pump magnetic nanoparticles of a specific size and therefore specific...
