Cobalt Sucker Rod Refurbishment

Cobalt sucker rod inspection services offer the most cost-effective method to extend sucker rod longevity, lower lifting costs, and reduce downtime.

Sucker rods are a simple but very critical component in artificial lift well completions.

Cobalt’s comprehensive sucker rod inspection and refurbishment services are designed to maximise sucker rod life cycle as well as reduce downtime and well operating expenses.

Thread Gauging for Tubing and Sucker Rod threads.

For threaded connections used in well completions (Tubing or Sucker Rods) it is very important that correct gauging practice and thread inspection should conform to the requirements of the relevant API Specification. 

Cobalt NDT Inspectors are qualified and experienced to ensure your threaded connections are cleaned, measured, gauged correctly and then protected, ready for the next well completion.

Electro-Magnetic Inspection

Electromagnetic inspection (also known as electromagnetic induction) has been proven to be the most efficient and effective method for detecting defects that can shorten the life of tubulars.

EMI is capable of detecting a much wider range of defects than other testing methods – including fatigue cracks, corrosion, pits, cuts, washouts, and more. This advanced technology utilises a device that can automatically scan the entire length of the tubulars for defects.

Magnetic Particle inspection

Magnetic particle testing is utilized to inspect ferromagnetic materials (those that can be magnetized) for defects located at or near the surface.

This technique is highly effective in detecting cracks, stress fractures, and other surface flaws. 

Main Advantages:
Large surface areas of complex parts can be inspected rapidly
Can detect surface and subsurface flaws
Magnetic particle indications are produced directly on the metal surface and form an image of the discontinuity or defect. 

Tubing and Sucker Rod Thread Protectors

Cobalt has designed (Patent Pending) an innovative Sucker Rod Thread Protector for Sucker Rods and Couplings.

Engineered to lock onto the thread relief so they do not vibrate off during transport and for effective protection of the threads and pin shoulder faces.

Cobalt has also designed an innovative new Thread Protector specifically for oilfield tubing. 

Sucker Rod Inspection

Cobalt inspection techniques identify which sucker rods are suitable for further service, limited service, or which need to be removed from service and discarded.

All inspections are performed by ASNT-qualified Level I and II inspectors using Cobalt’s proven technologies, proprietary inspection equipment, and software.
