Aspectos ambientais relevantes na construção de poços de petróleo para a prevenção da contaminação em aquíferos

Abstract

This article establishes the environmental aspects related to the contamination of aquifers that are inherent to the process of building oil wells. The lack of studies that address this issue as well as its relevance at a global level for the conservation of water resources warrant its realization. The aspects were determined through investigative and bibliographical research, presenting the following relevant points: the location and extension of the aquifer-bearing formation; the structural integrity related to well casing and cementing, and drilling fluid characteristics. Establishing the critical factors are instrumental in guiding stakeholders in the exploitation of mineral reserves in a sustainable manner.
