| 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. |
