Analysis and experimental study of oil well indicator diagram based on electric parameter method
Energy Reports, 2022 At present, the load diagram of pumping wells mostly uses load sensors to obtain load data. However, the load sensor is prone to mechanical fatigue during the measurement process, which results in measurement data drift distortion and large errors.

Electric submersible pump grounding [PDF]
IEEE Industry Applications Society 50th Annual Petroleum and Chemical Industry Conference, 2003. Record of Conference Papers., 2003 Although electric submersible pumps (ESPs) have been produced for almost 100 years, the actual causes of certain electrical failures are still unknown. Why do failures occur on startup or two weeks after an electrical storm? Most of the answers to these questions can be found from an analysis of traditional grounding techniques and consideration of how
