System and Method for Verifying Perforating Gun Status Prior to Perforating a Wellbore
First Claim
1. A method for verifying perforating gun status prior to perforating a wellbore comprising:
- running a perforating gun having a leak sensor disposed therein to a target location within the wellbore on a tubing string;
integrating a communication system with the tubing string, the communication system operable to communicate with the leak sensor;
sending a first telemetry signal via the communication system to interrogate the leak sensor regarding a leak status of the perforating gun;
returning a second telemetry signal from the leak sensor via the communication system including the leak status of the perforating gun; and
determining whether to operate the perforating gun based upon the leak status information.

Abstract
A system for verifying perforating gun status prior to perforating a wellbore. The system includes a perforating gun (38) having a leak sensor disposed therein that is positionable at a target location within the wellbore on a tubing string (30). A communication system (42, 44, 46, 48, 50) is integrated with the tubing string (30). The communication system (42, 44, 46, 48, 50) is operable to communicate with the leak sensor. A surface controller (40) is operable to send a first telemetry signal via the communication system (42, 44, 46, 48, 50) to interrogate the leak sensor regarding a leak status of the perforating gun (38), receive a second telemetry signal from the leak sensor via the communication system (42, 44, 46, 48, 50) including the leak status of the perforating gun (38) and determine whether to operate the perforating gun (38) based upon the leak status information.
