Contribution to the environmental performance of the dry-vibratory drilling technology

The self-vibratory drilling (SVD) is an innovative technology that allows increasing the productivity, without coolant. The aim of this paper is to prove that the environmental impacts of SVD are significantly less than those of traditional drilling (TD) and to quantify them. The study is based on a life cycle analysis of both processes. The major contributor to the environmental impacts in TD is the coolant. The new major contributors in SVD are the twist drills. A model that links the lifespan of the twist drills and the environmental impacts of SVD has been developed to support decisions for R&D.
