ABSTRACT

The extraction of natural resources from underground reservoirs depends heavily on the drill pipe, a vital part of the drilling industry. The drill pipe performance is thoroughly analysed in this study, taking into account a variety of elements such as material integrity, fatigue resistance, and corrosion susceptibility.The study takes a multidisciplinary approach, incorporating field data collecting, non-destructive testing (NDT), and metallurgical analysis. In controlled laboratory settings, samples with various compositions and operational histories underwent in-depth analysis. Important information on material characteristics, microstructure, and hardness profiles was discovered by metallurgical study. NDT techniques, such as visual inspection, SEM examinations, EDAX examinations, fractography, etc., supplied crucial information on the structural integrity and possibility for faults. Critical failure modes such as surface oxide cracking, hardbanding degradation, and in-service pitting were also covered in the study. Following root cause studies, specific suggestions for mitigation techniques were made. These suggestions included choices for materials, how to apply coatings, how to operate, and maintenance procedures.

The results of this study provide useful information to drilling industry stakeholders, enabling them to make well-informed decisions on the choice, use, and maintenance of drill pipes. The study also advances best practises for extending drill pipes' useful lives and improving their performance in varied drilling conditions. It is advised to pursue additional research directions to investigate cutting-edge materials and technologies for even greater durability and efficiency in drill pipe operations.
