A fluid management system positioned in a wellbore for recovering a multiphase stream from the wellbore. The system comprising a downhole separator configured to produce a carrier fluid having a carrier fluid pressure and a separated fluid having a separated fluid pressure, an artificial lift device configured to increase the carrier fluid pressure to produce the turbine feed stream having a turbine feed pressure, a turbine configured to convert fluid energy in the turbine feed stream to harvested energy, the conversion fluid energy from the turbine feed stream to harvested energy produces a turbine discharge stream having a turbine discharge pressure less than the turbine feed pressure, and a pressure boosting device configured to convert the harvested energy to pressurized fluid energy, the conversion of harvested energy to pressurized fluid energy produces a pressurized fluid stream having a pressurized fluid pressure greater than the separated fluid pressure.

Fluid driven commingling system for oil and gas applications

A system and method for boosting the pressure of a low-pressure multiphase mixture into a high-pressure multiphase mixture. The system includes a gas-liquid separator, a liquids pump and a liquid piston compressor. The method includes introducing the low-pressure multiphase mixture into the pressure boost system, operating such that a low-pressure liquid and a low-pressure gas form, boosting the pressure of the low-pressure liquid to a high-pressure liquid, introducing low-pressure gas during a charging period into the liquid piston compressor, converting the low-pressure gas into high-pressure gas using the high-pressure liquid during a compression period, discharging the high-pressure gas form the liquid piston compressor, and mixing the high-pressure liquid and gas such that the high-pressure multiphase mixture.
