Abstract
A power transmission and data communications system for use in a gas or oil well borehole is disclosed. The borehole includes a casing and a piping structure therein and at least one downhole equipment module located therein. The system provides for the power signal that is used to provide power transfer to be modulated with data and control signals that are to be transmitted to the downhole equipment located in the downhole equipment modules. In particular, the system provides for the power/data signal to be electrically coupled to the case and piping structure for transmission downhole. The downhole equipment includes a power supply that is operative to recover the power signal portion of the power/data signal and to provide power to the other downhole equipment. A downhole receiver is operative to recover the data portion of the power/data signal and to demodulate the data provided thereon. The system can further include a downhole data source coupled to a downhole transmitter for impressing the downhole data onto the case and piping structure for transmission uphole. A receiver contained in the surface equipment is operative to receive and recover the transmitted downhole data for analysis and storage by surface equipment.
