In the Oil and Gas industry 3 phase squirrel cage induction motors are commonly used for powering sucker rod pumps. In order to identify potential optimization of the pumping jack prime mover for field operations, a testing facility is required for analysing the engines performance in a controlled and safe environment. The thesis focuses on the steps that have been taken to build up a test stand to simulate the operational strain that the induction motor is subjected to during production operation. The testing is performed by connecting a prime mover to a second engine that simulates the torque that is applied to the engine while pumping oil to the surface. Additionally, to the VSD drives, that each engine is equipped with, a control unit had to be introduced to the second motor to display the characteristic torque of the pumping simulator. A major part of the thesis illustrates the installation of a measurement system, the data acquisition phase and the means necessary for accurate data processing. The testing facility measurement instruments will provide an insight into both engines performances by analysing the current, voltage, torque, speed and position of the shaft. Furthermore, the thesis will also provide a more detailed insight into electric losses during certain operational states. The test stand aims to provide an insight into the 3 phase squirrel cage induction motors capacity and potential by providing a specific torque scenario through the pump simulator. Therefore, the testing allows to identify the parameters to optimize an induction motor to a more energy efficient prime mover.
