Oil exploration is one of the main industrial activities in the country, due to the variety of by-products and companies involved in the sector. In order to be able to extract such a product from the sedimentary basins, it is necessary to invest in large and high technology. Drilling platforms and services are among the main activities that represent significant costs for the execution of the exploration service. In order to enable the investment and commercialization of the oil barrel, these activities must be improved in order to attract investors to explore oil fields in an increasingly efficient and productive way, thus contributing to the generation of wealth and development of society. Within this scenario, the objective of this article was the application of data modeling in a set of operational parameters to support the evaluation of the efficiency of the offshore drilling process. Because it is a process involving different input and output variables, it is pertinent to analyze wells in homogeneous areas and to identify the main parameters that allow contributing to the best performance in the rate gain in perforated meters. In this sense, in the aspect of the methodological approach, the efficiency calculation was evaluated, based on the parameters pre-established by the drilling engineering, adopting, for the modeling, the classic, output-oriented model, used by the data wrap analysis. The results obtained, from the variables and the applied model, allowed a preliminary perception of the efficiency of the drilling system.
