Abstract
Systems and methods for wireless downhole telemetry are provided. The system includes a tubular located in a wellbore; a pressure controller located at or near a surface of the wellbore to send a digital command via a change in a pressure applied to the tubular; and a receiver disposed in the wellbore, wherein the receiver includes a mechanical pressure switch to detect the change in the pressure applied to the tubular.
Claims11
A system comprising:
- a tubular located in a wellbore;
- a pressure controller located at or near a surface of the wellbore to send a digital command via a change in a pressure applied to the tubular;
- and
- a receiver disposed in the wellbore, wherein the receiver includes a mechanical pressure switch connected to a fluid meter configured to detect a change in the pressure that exceeds a change threshold within a time limit and to create an electrical connection in response to the change in the pressure that exceeds the change threshold within the time limit, and wherein power is not supplied to the receiver disposed in the wellbore until there is a detected change in pressure by the mechanical pressure switch.

A method comprising:
- changing a pressure applied to a tubular disposed in a wellbore;
- detecting a pressure change that exceeds a change threshold within a time limit with a receiver disposed in the tubular, wherein the receiver includes a mechanical pressure switch connected to a fluid meter, wherein power is not supplied to the receiver disposed in the wellbore until the detected change in pressure by the mechanical pressure switch;
- and
- creating an electrical connection based on the detected pressure change using the mechanical pressure switch.
