The present article consists of a study focused on the analysis of processes of qualification acquisition experienced by industrial workers in the field of petroleum -petrochemicals. This research identified the loci of qualification acquisition of operatives working in three distinct oil process units, which differ from the others in terms of technological advancement and importance to the production process. A major finding of the study is that the place of work represents the main source of qualification for oil process operatives, independently of the unit investigated. Social milieu influences and knowledge acquired through school and professional education also proved to be important for the qualification process.
