Abstract
A system and method enable telemetry between a downhole device located in a wellbore and an uphole device. Electrical signals are communicated between locations via at least one fluid carrying control line. The control line provides a path for fluid flow as well as for the transmission of electrical signals. Thus, electrical signals may be transmitted from one location to another within a wellbore without separate electrical wires or cables.
Claims56
A system for use in a wellbore, comprising:
- a well system deployed within the wellbore, the well system having:
- a fluid carrying control line with an insulation layer;
- and
- an electrical return, wherein electrical signals are carried by the fluid carrying control line.
