Abstract: Systems and methods of detecting an intersection between a wellbore and a subterranean structure that includes a marker material. The systems and methods include drilling the wellbore and determining that the wellbore has intersected a portion of the subterranean structure that includes the marker material by detecting the marker material. The systems and methods also may include distributing the marker material within the subterranean structure, aligning the marker material within the subterranean structure, determining one or more characteristics of the marker material, ceasing the drilling, repeating the method, and/or producing a hydrocarbon from the subterranean structure. The systems and methods further may include forming an electrical connection between an electric current source and a granular resistive heater that forms a portion of the subterranean structure, forming the granular resistive heater, and/or forming the subterranean structure.
