Sustainable Construction of Deep-Water Injection Wells: A Life Cycle Assessment Approach.

The study evaluates the environmental sustainability of constructing deep-water injection well systems for waste management. As the use of these systems is developing in Qatar, there is no research on their impacts from a sustainability point of view. The research aims to provide useful insights through a comprehensive life cycle assessment of constructing such wells. The analysis examines key construction stages: mobilization, drilling and casing, geophysical surveying, well development, wellhead assembly, and data logger installation for ground-term monitoring. Each stage is evaluated for its environmental and socio-economic effects. Initial findings show that while construction poses some environmental challenges, particularly regarding drilling and material use, the long-term environmental and social benefits may outweigh these concerns. The paper sheds light on the environmental implications of constructing deep-water injection wells and identifies initial opportunities to enhance their sustainability. The findings can serve as an important reference for the future development and sustainable operation of these waste management systems. [ABSTRACT FROM AUTHOR]
