METHOD OF MEASURING PARAMETERS OF A POROUS MEDIUM USING NANOPARTICLE INJECTION

摘要

The present disclosure relates to methods and apparatuses for evaluating a porous earth formation. The method may include estimating at least one parameter of interest of the earth formation using a displacement velocity of nanoparticles injected into the porous earth formation and exposed to an alternating magnetic field. The method may include using at least one processor to estimate the value of the at least one parameter. The apparatus may include an alternating magnetic field source, nanoparticles responsive to a magnetic field, and a sensor configured to measure the motion of the nanoparticles.
