Beschreibung
Zusammenfassung:	A system and method of injection well identification using tracer particles is disclosed. A collector-reader for analyzing magnetic particles in a fluid that is moving with respect to the collector-reader includes an array of magnets whose magnetization direction is varied so as to create regions of high magnetic field gradient in the fluid, a stopper configured to concentrate spatially the particles attracted to the array, and a reader including a source configured to excite the particles concentrated by the stopper and a detector configured to capture a particle excitation signature emitted by the magnetic particles. A method for observing a subterranean reservoir penetrated by a production well and two or more injection wells is also disclosed.
