Abstract

See full text

A method for mapping and monitoring of hydraulic fracture includes capturing, using an array of sensors, a first magnetic image of a well pay zone. A second magnetic image is captured using the array of sensors, after a well bore is padded with a fluid. A background is established based on the first and the second magnetic images. A third magnetic image is captured using the array of sensors, after a doped proppant is injected into a stage. The third image is processed to subtract the background and to obtain information regarding distribution of the fluid and the proppant in the stage.
