Abstract:
Born Scattering Inversion (BSI) systems and methods are disclosed. A BSI system may be incorporated in a well system for accessing natural gas, oil and geothermal reserves in a geologic formation beneath the surface of the Earth. The BSI system may be used to generate a three-dimensional image of a proppant-filled hydraulically-induced fracture in the geologic formation. The BSI system may include computing equipment and sensors for measuring electromagnetic fields in the vicinity of the fracture before and after the fracture is generated, adjusting the parameters of a first Born approximation model of a scattered component of the surface electromagnetic fields using the measured electromagnetic fields, and generating the image of the proppant-filled fracture using the adjusted parameters.

Claim (Index 1):
A system, comprising:\n a casing placed within a well bore extending from Earth's surface to a subterranean geologic formation; proppant and a conductive material; an electric current source in electrical communication with at least a portion of the casing, at least a portion of the conductive material and a plurality of sensors at a set of sensor locations; a database that stores:\n a geophysical model of a volume of Earth including the geologic formation and the well bore, \n a set of locations within the volume, \n an electromagnetic model, and \n the set of sensor locations; and \n a processor configured to:\n predict electromagnetic field values at the set of sensor locations using the electromagnetic model and the geophysical model by:\n computing primary electric and/or magnetic field values at the set of locations within the volume; and \n computing secondary electric and/or magnetic field values at the set of sensor locations using the primary electric and/or magnetic field values at the set of locations within the volume, \n receive measured electromagnetic field data gathered at the set of sensor locations, \n adjust, based on the measured electromagnetic field data, the predicted electromagnetic field values, \n determine a location of the proppant using the adjusted predicted electromagnetic field values, and \n generate an image of the proppant using the adjusted predicted electromagnetic field values.
