Non-intrusive inspection methodology of landing base and surface pipe
A system includes an equipment platform, an electro-magnetic defectoscopy tool, a signal emitter, a signal receiver, and a computer processor. The equipment platform is formed in a ring-like shape having an orifice of a size large enough to fit a circumference of the wellhead or the casing string within the orifice. The electro-magnetic defectoscopy tool is mounted to the equipment platform. The signal emitter is located in the electro-magnetic defectoscopy tool and is configured to emit a signal towards the orifice of the equipment platform. The signal receiver is located in the electro-magnetic defectoscopy tool and is configured to receive a reflected signal from the wellhead or the casing string. The computer processor is electronically connected to the signal receiver and is configured to receive and use the reflected signal to determine a condition of the wellhead or the casing string.
1. A system for inspecting a wellhead and a casing string, the system comprising:

a signal receiver located in the electro-magnetic defectoscopy tool and configured to receive a reflected signal from the wellhead or the casing string; and
a computer processor electronically connected to the signal receiver and configured to receive and use the reflected signal to determine a condition of the wellhead or the casing string.
2. The system of claim 1 , wherein the signal emitter of the electro-magnetic defectoscopy tool is configured to emit more than one electromagnetic signals each having a different strength and depth of investigation.
3. The system of claim 1 , wherein the signal emitter of the electro-magnetic defectoscopy tool is configured to emit a sonic signal towards the orifice of the equipment platform.
4. The system of claim 1 , wherein the condition of the wellhead or the casing string further comprises a thickness of walls within the wellhead or the casing string.
5. The system of claim 1 , wherein the equipment platform further comprises one or more lifting hooks.
6. The system of claim 5 , wherein the lifting hooks are connected to a wireline.
7. The system of claim 6 , wherein the wireline is electronically and physically connected to a logging truck configured to use the wireline to raise, lower, and rotate the equipment platform.
8. The system of claim 1 , wherein the equipment platform further comprises a data transmitter cable.
9. The system of claim 8 , wherein the electro-magnetic defectoscopy tool is electronically connected to a wireline through the data transmitter cable.
10. The system of claim 9 , wherein the wireline is electronically connected to the computer processor.
11. A method for inspecting a wellhead and a casing string, the method comprising:
disposing an equipment platform, formed in a ring-like shape and having an electro-magnetic defectoscopy tool, around the wellhead or the casing string;
emitting a signal from a signal emitter located in the electro-magnetic defectoscopy tool towards an orifice of the equipment platform;
receiving a reflected signal at a signal receiver located in the electro-magnetic defectoscopy tool from the wellhead or the casing string; and
performing an inspection of the wellhead and the casing string by determining a condition of the wellhead or the casing string using the reflected signal and a computer processor electronically connected to the signal receiver.
12. The method of claim 11 , wherein emitting the signal from the signal emitter further comprises emitting more than one electromagnetic signals each having a different strength and depth of investigation from the signal emitter.
13. The method of claim 11 , wherein emitting the signal from the signal emitter further comprises emitting a sonic signal from the signal emitter towards the orifice of the equipment platform.
14. The method of claim 11 , wherein determining the condition of the wellhead or the casing string further comprises determining a thickness of walls within the wellhead or the casing string.
15. The method of claim 11 , wherein disposing the equipment platform around the wellhead or the casing string further comprises installing one or more lifting hooks to the equipment platform.
16. The method of claim 15 , wherein disposing the equipment platform around the wellhead or the casing string further comprises connecting a wireline to the lifting hooks.
17. The method of claim 16 , wherein disposing the equipment platform around the wellhead or the casing string further comprises raising, lowering, or rotating the equipment platform using a logging truck physically and electronically connected to the wireline.
18. The method of claim 11 , wherein determining the condition of the wellhead or the casing string using the computer processor further comprises sending the reflected signal from the signal receiver to the computer processor.
19. The method of claim 18 , wherein sending the reflected signal from the signal receiver to the computer processor further comprises transmitting the reflected signal from the signal receiver to a wireline using a data transmitter cable located in the equipment platform.
20. The method of claim 19 , wherein sending the reflected signal from the signal receiver to the computer processor further comprises transmitting the reflected signal from the wireline to the computer processor.
