The invention generally relates to data transmission in a wellbore. In one aspect, a system for communicating electromagnetic waves in a wellbore is provided. The system includes a sensor equipment package for sensing a parameter in the wellbore and generating an electromagnetic wave. The system further includes an expandable composite tubular having a conducting member and an insulating member. The composite tubular is configured to be expanded from a first diameter to a second larger diameter, wherein the composite tubular in the second larger diameter forms a connection with the wellbore. In another aspect, a method of using a system for communicating electromagnetic waves in a wellbore is provided. In a further aspect, a system for providing electrode contact surfaces between a sensor equipment package and a surrounding tubular disposed in a wellbore is provided. |
