Abstract
This chapter presents an in-depth analysis of Copper oxide nanoparticles
(CuONPs) and their emerging role in the oil and gas industry. Over the past five years,
nanomaterial technology, especially CuONPs, has attracted significant attention due to
its diverse applications in fields like petroleum. In the context of the oil and gas
industry, CuONPs have been revolutionary, particularly in enhancing oil recovery
(EOR) and as innovative drilling fluids. Their application leads to more efficient
extraction and reduced viscosity of trapped oil. The synthesis of CuONPs has evolved,
with biological methods standing out for their cost-effectiveness, safety, and
environmental friendliness. These green synthesis methods have redefined industry
standards by offering a sustainable alternative to traditional physical and chemical
approaches. The chapter aims to provide a comprehensive overview of the practical
applications of CuONPs in the oil and gas sector, emphasizing their production through
green routes. It also addresses the challenges and prospects of CuONPs, setting a
foundation for further research and technological advancements in this field.
