How do you inspect a tubing?
The outside of each tubing joint should be inspected visually for mill defects such as seams, slugs, pits, cuts, gouges, dents, or cracks. Each connection should be checked for defective threads and seals. Wall thickness measurements should be considered on critical wells.
What is casing inspection?
1. n. [Production Logging] An in situ record of casing thickness and integrity, to determine whether and to what extent the casing has undergone corrosion.
What is EMI tubing inspection?
Electro-Magnetic Inspection (EMI) has been proven to be a very effective method for detecting defects that can shorten the life of your drill pipe, including fatigue cracks, corrosion, pits, cuts, washouts, wall loss, and more.
What is tube inspection?
Tubes may be inspected using Eddy Current (ECT), non-destructive testing (NDT) from the outer diameter (OD), usually at the time of manufacture and from the inner diameter (ID), usually for in-service inspection, particularly for heat exchanger inspection.
What is corrosion logging?
Multi Barrier Corrosion logging is designed to evaluate remaining metal thickness of the well completion elements such as a tubing and/or casing, up to 3 barriers, based on emission and receipt of electromagnetic field with following computation of data in software.
How does a cement bond log work?
A cement bond log documents the evaluation of the integrity of cement work performed on an oil well. In the process of drilling and completing a well, cement is injected through the wellbore and rises up the annulus between the steel casing and the formation.
What is drill pipe inspection?
Drill pipe inspections are imperative to ensuring the drill pipe remains reliable and safe to use in operation. The inspection identifies when pipe or other drill stem elements must be repaired, reinforced or retired due to integrity issues.
What are the stages of inspection for tube sheet?
Stages of Inspection
- Approval of detailed fabrication drawings submitted by vendor/client.
- Material identification based on Mill Certificates or testing at Laboratories.
- Stamp transfer on all pressure parts.
- Testing and approval of welding procedures and welders.
In what principle cement evaluation is based on?
The main objective of the cement evaluation process is to evaluate the hydraulic isolation of the cement sheath. The main principle of cement bond log (CBL) tools is to send an acoustic signal inside the casing and measuring the acoustic impedance of the cement between the casing and the formation.
What is a USIT log?
The USI* UltraSonic Imager tool (USIT) uses a single transducer mounted on an Ultrasonic Rotating Sub (USRS) on the bottom of the tool. The transmitter emits ultrasonic pulses between 200 and 700 kHz and measures the received ultrasonic waveforms reflected from the internal and external casing interfaces.
