The selection of artificial intelligence (AI) techniques in the petroleum industry is very efficient because it will have a direct impact on the outcome of the study and the future use of the operation. In this study, we discuss the efficiency of the AI techniques by verification the results of permeability of a lower Albian carbonate reservoir of Campos Basin using the Winland method and cluster analysis. The permeability measured by AI techniques as fuzzy logic (FL), artificial neural network (ANN) and genetic algorithm (GA) were applied in three wells, being the first used for learning and the others as blind tests. Well logs are gamma ray, density, sonic, neutron porosity and SDR permeability logs. ANN obtained better performance compared to the FL, but the results have become better with GA. Employing artificial intelligence (AI) modern techniques together with a dataset composed by well logs, lithological information and sample laboratory measurements of permeability and porosity.

Automation of human activities through computational methods is essential in today's world, whether in the academic world, in the corporate world or in everyday tasks, and in geophysical processing is not different. Much of the time spent processing a shallow refraction seismic study is spent on picking for first break identification, which, despite technological advances, remains dependent on the visual evaluation of the seismic interpreter. Thus, the automation of this process provides a more efficient result and provides more time for interpretation. In this work we used the peak detection program (Zscore). The application of the Z-score showed automatic picking efficiency, identifying 88% of the first breaks, with 92% of the detections having an error less or equal to 2%. In addition, a method for interpreting seismic events, identifying the velocities and thicknesses of the layers, was successful: Simultaneous Inversion. Thus, several automations in the processes of the seismic refraction method have proved to be satisfactory in real data.
