Oil is a very complex chemical system, as for instance, the paraffinic type which was considered as a fluid to be evaluated in this scientific paper, trough the static interfacial tension with the surfaces of the API 5L grade B conduction pipe and the EPOXY and EPOXY M resins. The paraffinic oil produced in the 7-PIR-244D-AL well, which is located in the producing field of Pilar in the state of Alagoas, presents special characteristics concerning its flow which are different from the other oils in the Sedimentary Basin of Sergipe and Alagoas. The resin used in the experiments were the EPOXY, commercially know as DGEBA, as well as EPOXY M, which was produced from the DGEBA with the addition of a substance whose objective is to reduce the deposit of organic and/or inorganic molecules in its surfaces along the oil flow. The evaluation of the static interfacial tension between this type of paraffinic oil and the surfaces of the EPOXY (37,2 mN/m), EPOXY M (14,8 mN/m) resins and the steel pipe (4.790,2 mN/m) has produced results, the performance of this fluid compared with the EPOXY M resin was better than when compared with the EPOXY and, as a consequence, better than when compared with the metallic material of the pipe. As a result of the data got through the experiments with these materials, there was a conclusion about the possibility of practical use of the EPOXY M resin as a coating in the internal surface of the pipes that carry oil with a considerable quantity of paraffin in its composition, aiming at a better performance relating to the flow of this fluid.
