Abstract
A technique provides a system and method to verify attachment of a fishing tool with a downhole well tool. The fishing tool comprises a latching mechanism that latches onto the well tool to be retrieved. The fishing tool also comprises a detection device to verify connection of the latching mechanism. The detection device provides a signal uphole to verify attachment to the well tool.
Claims25
A method for use during a fishing operation in a well, comprising:
- deploying a fishing tool downhole into a wellbore;
- attaching the fishing tool to a fish;
- and
- transmitting a signal uphole during retrieval of the fish to indicate retention of the fish by the fishing tool.
1 more element
A device, comprising:
- a fishing tool for use in retrieving a fish from a wellbore, the fishing tool comprising:
- a latching mechanism for latching onto the fish;
- and
- a detection device cooperating with the latching mechanism to enable transmission of a signal uphole indicating the latching mechanism is latched onto the fish.
1 more element
A method, comprising:
- connecting a fishing tool to a fishing tool conveyance;
- coupling a communication line between a surface location and a detection device of the fishing tool;
- positioning the detection device to detect attachment of a fish to the fishing tool;
- and
- providing a signal uphole through the communication line when the detection device detects attachment of the fish.
