Abstract
A telemetry system for use in developing a field of wells has a first downhole device capable of transmitting and/or receiving signals disposed in an appraisal well, an electronics control system located at or near the top of the appraisal, a cable disposed in the appraisal well that provides signal communication between the first downhole device and the electronics control system, and a second downhole device capable of transmitting and/or receiving signals disposed in a second wellbore. The signal is passed through the cable between the first downhole device and the electronics control system. From there, the signal may be re-transmitted to a desired location.
