MOBILE, MODULAR, ELECTRICALLY POWERED SYSTEM FOR USE IN FRACTURING UNDERGROUND FORMATIONS USING LIQUID PETROLEUM GAS

摘要

The present invention provides a method and system for providing on-site electrical power to a fracturing operation, and an electrically powered fracturing system. Natural gas can be used to drive a turbine generator in the production of electrical power. A scalable, electrically powered fracturing fleet is provided to pump fluids for the fracturing operation, obviating the need for a constant supply of diesel fuel to the site and reducing the site footprint and infrastructure required for the fracturing operation, when compared with conventional systems. The treatment fluid can comprise a water-based fracturing fluid or a waterless liquefied petroleum gas (LPG) fracturing fluid.

主权项

1. A system for hydraulic fracturing, comprising:
at least one pump adapted to pressurize and pump fracturing fluid into a wellbore at a well site; at least one electric motor operatively coupled to the at least one pump such that the at least one electric motor is adapted to power the at least one pump; and at least one dedicated source of electricity for fracturing operations on the well site, wherein the at least one dedicated source of electricity comprises a turbine generator, and wherein the at least one dedicated source of electricity is operatively coupled to the at least one electric motor such that the dedicated source of electricity is adapted to supply electricity to the at least one electric motor for driving the at least one pump.
