According to an aspect, the positioning system includes a distance measurement system. The autonomous wellbore tool may include one of a perforating gun and a transmitter plug assembly.
Claims13
An autonomous wellbore tool comprising:
- a plug assembly;
- a positioning system provided on the plug assembly, wherein the positioning system comprises a distance measurement system;
- a communication system housed in the plug assembly;
- and
- a perforating gun, wherein the perforating gun comprises:
- a detonator including an electronic circuit board;
- a first perforating gun;
- and
- a second perforating gun,
- wherein the communication system is configured to communicate with the electronic circuit board, and wherein the communication system is configured distinguish between the first perforating gun and the second perforating gun.
7 more elements
An autonomous wellbore tool comprising:
- a transmitter plug assembly;
- and
- a sonar device secured to the transmitter plug assembly, wherein the sonar device is configured to find an object in a wellbore casing, wherein the sonar device comprises an active sonar transducer that emits an acoustic signal or pulse of sound when the autonomous wellbore tool is positioned in the wellbore casing,
- wherein the active sonar transducer is configured to determine the range and orientation of an object in the wellbore casing, and wherein the active sonar transducer is configured to receive a return signal from the object in the wellbore casing.
1 more element
A method of identifying a position of an autonomous tool in a wellbore, the method comprising:
- deploying the autonomous tool in the wellbore, wherein the autonomous tool comprises:
- a plug;
- and
- a sonar device coupled to the plug;
- setting the plug;
- and
- using the sonar device, determining a position of a subsequently deployed perforating gun relative to the plug,
- wherein the autonomous tool further comprises a perforating gun secured to an upper end of the plug, the perforating gun comprising a detonator, a detonating cord, and a shaped charge, and
- wherein the method further comprises transmitting a firing signal from the plug to the detonator to detonate the shaped charge, wherein the firing signal is transmitted from the communication system of the plug.
