SUMMARY:

In the petroleum engineering/industry, automation and control of oil wells stand out due to the relevant results when applied correctly, thus becoming indispensable in the oil industry to achieve maximum performance from each well. Sucker-rod pumping is an artificial lift method applied to onshore environments, it is the most used method in the world, in number of installed wells. In order to introduce new control techniques to this method, this work comes with the proposal of developing a control strategy for pumping speed optimization. The developed tool uses the speed variation during the cycle, in order to increase the average pumping speed and to mitigate the negative effects related to this increase. A proportional integral derivative controller (PID) was used. Initially, a bibliographic survey on the subject was carried out, covering patents and studies that had as theme the variation of the pumping speed, as well as the basic concepts about the PID control and the role of the surface and subsurface dynamometer charts. To implement the control, it was used the programming language Visual Basic for Applications (VBA). For validation, a simulator was used as a virtual well and simulations were performed with the developed controller, comparing the results obtained before and after the control application. As a result, it was observed that the strategy developed was able to optimize the production in SRP systems, considering that there was an increase in the effective piston stroke, followed by an increase in the pumping speed, with an increase of the well production.
