The study aims to provide guidance for economist engineers in initiating and developing forms of entrepreneurship as regards the marketing of oil products (hereinafter referred to as "products"), using the case study as a research method. The following techniques have been used within the architecture of the study: study questions; the study hypothesis; primary, contextual (existence of the case) and embedded analysis units; the idea of linking data to hypotheses; criteria for data interpretation. Before proceeding to a subsequent stage, a preliminary theory on the concepts discussed has been developed. The data collection stage is followed by the data analysis stage. At the end of the study, conclusions and bibliography are included. Entrepreneurship in the marketing of oil products is regarded both from its perspective as a business opportunity (interest) for economist engineers and as a necessity for the market.
