he oil industry has a significant and important share in the world energy matrix with an estimated production of 1/3 of the global energy. With the high world oil consumption, resource management needs to be better managed in order to reduce the associated environmental impacts. One of the main environmental concerns associated with the exploration and production of oil fields is related to the generation of water produced from petroleum. The water produced from the production of oil and gas is a strategic challenge for companies, as it generates the largest share of waste from the oil industry. In this perspective, this work aims to analyze the performance of environmental sustainability, based on the generation of oil produced water, from the onshore fields of the coastal oil basins of Brazil. The data were made available by the ANP (National Agency of Petroleum) in its electronic site making a total of 156 oilfields belonging to the basins of Alagoas, Camamu, Espírito Santo, Potiguar and Sergipe. The years analyzed were 2014, 2015 and 2016. In order to reach the proposed objective, a conceptual model was formulated with 12 hypotheses. The results were presented in four stages: stage I - presentation of the results of the descriptive statistics; stage II - analysis of multiple regressions; stage III - application of the median; stage IV - Dynamic modeling analysis (DDEA) and presentation of a two-dimensional graphical analysis of DDEA; and stage V - analysis of logistic regressions. Two statistical tests were used to validate the hypotheses: T-test and Wald test. The expected results will help the managers in the managerial decision making from the model proposed for the petroleum sector.
