Novel Reciprocating Submersible Pumping Technology for Performance Improvements in Oil Production

Submersible pumping technique with linear motor is crucial for oil production in low permeability reservoir, especially in<br>China and South East Asia. However, how to improve the life, reliability and performance of the submersible linear motor<br>and cut energy consumption is still a challenge for oil production engineers. To solve these issues, several novel designs on<br>lubrication, hydraulic buffer, floating suction device and automatic motor driven and control methodologies are proposed.
