1. A system for mapping and monitoring a hydraulic fracture, the system comprising: an array of sensors configured to capture a plurality of magnetic images comprising a first magnetic image comprising a magnetic image of a well pay zone of a well including a baseline magnetic profile including Earth's magnetic field, a second magnetic image comprising a magnetic image captured after the well pay zone is padded with a fluid, and a third magnetic image comprising a magnetic image after a doped proppant is injected into the well pay zone, each of the plurality of magnetic images comprising a set of one of more vector measurements using the array of sensors; and an analyzer in communication with the array of sensors and comprising a processor configured to determine a background image based on the first and the second magnetic images and to process the third magnetic image to subtract the background image to obtain information regarding a distribution of the fluid and the proppant in the well pay zone.
