Non-Destructive Testing

Timely inspection and evaluation of the equipment and tools is a necessary condition to prevent failures or deterioration of their condition leading to an increase in the cost of repairs and nonproductive time.

“Endevour” provides service inspection and non-destructive testing in accordance with the international standards and the best world practices, involving highly skilled personnel and modern equipment, providing accurate and reliable results.

NDT laboratory of our company is able to carry out a full range of drilling tools and equipment tests both on the production bases and in the field using the following methods:

  • visual-optical (VT);
  • magnetic particle (MT);
  • penetrant (PT);
  • ultrasonic (UT);
  • electromagnetic (ET)
  • radiographic (RT)

Work on non-destructive testing is conducted by experts trained, tested and certified in accordance with the ASNT TC-1A, as well as internal rules of Ukraine NPAOP.

The inspection can be carried out according to the standards API, DS-1, NPAOP, NS-2, internal standards or other standards specified by the Customer.

During the service work we have inspected tens of thousands of pieces of drilling equipment and tools and prevented hundreds of accidents through the use of low-quality tools and equipment.

Quality inspection and NDT ensure confidence in operability of equipment and the absence of hidden defects providing for:

  • the safety of life and health of personnel;
  • maximizing equipment life through timely maintenance and reducing its value;
  • reducing the risk of losses from failures of equipment and complications during drilling;
  • effective process performance through timely detection of defects before they lead to serious consequences;
  • the ability to make correct decisions on management of drilling based on accurate and objective data;
  • reducing non-productive time, increasing the speed of drilling, and thus, reducing the overall cost and timely receipt of products.

Objectivity and reliability of inspection results is ensured by impartiality of the Contractor as a disinterested third party, and availability online for inspection and analysis.

Basic types of control of drilling tools and equipment:

  1. incoming inspection of drill pipes, tubing and casing to meet manufacturer’s claims and specifications (thickness measurement of pipe body, hardness test of pipe material, coercimetry, ultrasonic inspection for manufacturing defects);
  2. control of drill pipes before drill feed to meet API and DS-1 requirements;
  3. drill pipes planned control during pulling-out according to local standards;
  4. planned control of drilling equipment (drawworks, power tongs, elevators, swivels, traveling block, crown blocks);
  5. drilling rigs and their foundations scheduled control.

 

Methods of Non-Destructive Testing:

  1. Visual-optical method (VT):
  • checking of drilling tools for physical deterioration;
  • endoscopy of hard-to-get-to elements of equipment and the inner surface of OCTG;
  • quality control of threaded pipe joints by local standards using thread gages and thread templets, conemeters, depth gages, calipers.
  1. Magnetic particle method (MT):
  • fluorescent control of threaded sections of drill pipes;
  • control of potentially unreliable areas of drilling tools;
  • defectoscopy of equipment.
  1. Ultrasonic method (UT):
  • control of end sections of drill pipe;
  • ultrasonic thickness measurement;
  • body scan of drilling pipes, casing and tubing.
  1. Penetrant method (PT):
  • control of non-magnetic drilling tools and equipment.
  1. Electromagnetic method (ET):
  • detection of defects of threaded connections, drilling equipment and tools: drill pipes, drill collars, crossover subs, etc.
  1. Radiographic (RT):
