Abstract
An interwell tomography method includes casing a first borehole with a casing tubular having at least one transmission crossover arrangement, each transmission crossover arrangement having an adapter in communication with a coil antenna that encircles an exterior of the casing tubular. The method also includes deploying, inside the casing tubular, a conductive path that extends from a surface interface to the at least one transmission crossover arrangement. The method also includes providing a set of one or more antennas in a second borehole. The method also includes obtaining electromagnetic (EM) measurements for interwell tomography using the at least one transmission crossover arrangement and the set of one or more antennas, where said obtaining involves conveying data or power between the at least one transmission crossover arrangement and the surface interface via the conductive path.
