Life cycle analysis of drilling fluid processing: Emission hotspots and sustainable mitigation strategies

This paper TG5 System boundary of Life cycle analysis for Fluid Processing explores the life cycle analysis (LCA) of drilling fluid processing at rig sites, focusing on emissions from various operational stages. Drilling fluids play a critical role in well construction, yet their management contributes to environmental impacts, particularly greenhouse gas (GHG) emissions. Using general data from industry practices and case studies of advanced fluid recovery, cuttings management, and waste treatment technologies, this study evaluates emissions associated with fluid mixing, circulation, reconditioning, storage, and disposal. By identifying carbon hotspots and assessing mitigation strategies, this analysis highlights opportunities for improving sustainability in drilling operations.
