Abstract :
This paper presents a study of a new proposal for down-hole dynamometer cards patterns for the automatic fault diagnosis of Sucker Rod Pumping System. The accuracy and quick identification of down-hole problems is essential to the risk decrease and production improvement of the petroleum industry. The main idea is a card recognition through a digital image processing (Fourier Descriptors) and statistical (Pearson Correlation) tools. Successful results were reached when this proposal was applied in simulated cards and PETROBRAS real cards.
