Abstract

A method and a system for pressure regulation of well fluid produced from a hydrocarbon well in a hydrocarbon production field. The system comprises a pump arranged on a well head in fluid communication with a process fluid passage from the well, the pump arranged for receiving well fluid produced from the well and to deliver the fluid to downstream piping or equipment. The pump comprises a motor/generator unit operable as a generator as the pump is driven by well fluid in power generation mode, and wherein the pump is driven in power consumption mode by operation of the motor/generator unit as a motor.
