Propuesta de un Modelo de Estimación de Velocidad de Corrosión Externa para Tuberías Enterradas en Suelos Arcillosos.

Many studies have shown the need in the Venezuelan oil industry to implement viable alternatives in the field of pipeline integrity management. Thus, the aim of this work is to propose a prediction model for the external corrosion rate of burned transmission pipelines in a crude oil production field with clay soils, Incated in the west of Zuha State in Venezuela. After the collection, revision and classification of soil and operating parameter data in the field, a definition of input and output variables was carried out, used to generate 2 models, one regression type and the other classification type. For the neural network model, a low regression fit (R) of 6.62% and an RMSE of 2.13 were obtained, indicators of low model efficiency due to the restrictions of the data provided and sample stre. On the contrary, for the decision tree classification model, un accuracy of 98 141% was obtained, when classifying the corusion rate in seventy ranges. This clasification tree model will serve as a starting point for subsequent research to dleve deeper into the area. [ABSTRACT FROM AUTHOR]
