Confirmation of Candidature - Candidate : Chundu Tamang

Oil and gas industries in Australia are generating over 300 metric tonnes of polymeric waste annually, the majority of which ends up in landfill. Primarily made from high performing but expensive Polyamide 6, sucker rod guides are exposed to downhole contamination, high temperatures and mechanical stresses during service. Currently, there is a limited understanding on the physical, mechanical, and chemical properties of used rod guides that will help identify their useful post-service pathways. This study aims to systematically evaluate the composition and characteristics of used guides, focusing on Polyamide 6 from identified wells. Thermal, chemical, and microstructural characterisation will be carried out and effective decontamination processes will be determined. Varying amounts of used rod guide materials will then be incorporated into virgin Polyamide 6 to determine the optimal amount of waste material that will not significantly affect its critical properties or diminish the product's performance. Prototype guides will be manufactured from this recycled material, and field testing will be carried out for compliance with industry standards. The results of this research will develop a better understanding of the characteristics of Polyamide 6 used in different well conditions and will help in developing a framework for the effective recycling and re-use of used rod guides. Consequently, this will contribute to reduced resource consumption, and creation of a circular economy in the oil and gas industry.
