Abstract:
A method facilitates transmission of electric signals across well components which move relative to each other in a wellbore environment. The method utilizes well components which are movably, e.g. rotatably, coupled to each other via one or more conductive bearings. Each conductive bearing has a conductive rolling element which enables relative movement, e.g. rotation, between the well components while simultaneously facilitating transmission of electric signals through the bearing. The method also involves coupling portions of the bearing to each of the well components, and those bearing portions may be connected with electric leads to enable flow of electric signals through the bearing during operation of the system downhole.
