Abstract
The precision and the fast identification of abnormalities of bottom hole are essential to prevent damage and increase production in the oil industry. This article presents a study about a new automatic approach to the detection and the diagnosis of faults in the Sucker-rod Pumping through dynamometric cards of bottom hole. The main idea is the recognition of the well production status through the image processing of the bottom´s hole dynamometric card (Boundary Descriptors) and Euclidean Distance. This proposal was implemented to oilfields cards of PETROBRAS with success.
