| Abstract: A system includes a receiver component that receives a model of a well
system, the model comprising a representation of an electrically
energized well casing and/or a fracture as a transmission line that leaks
electric current as the current traverses the well casing and/or
fracture. The receiver component also receives a value that indicates an
amount of the current that is applied to the well casing and a location
of a source of the current on the well casing. The system further
includes an electromagnetic field calculator component that calculates an
estimated electromagnetic field at at least one location on the surface
of the earth based at least in part upon the representation of the
electrically energized well casing and/or fracture, the value that
indicates the amount of current that is applied to the well casing, and
the location of the source of the current on the well casing. |
