Abstract
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.
Claims9
A system for hydraulic fracturing, comprising:
- at least one fracturing 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 fracturing pump such that the at least one electric motor is adapted to drive the at least one fracturing pump;
- 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 an electrical transformer, 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;
- and
- at least one blender for producing the fracturing fluid, wherein the at least one blender further comprises a first inlet pump, a second inlet pump, a first discharge pump, and a second discharge pump, and wherein the fracturing fluid comprises a liquefied petroleum gas.
A method for delivering a fracturing fluid to a wellbore, comprising:
- providing at least one fracturing pump adapted to pressurize and pump fracturing fluid into a wellbore at a well site;
- providing at least one electric motor operatively coupled to the at least one fracturing pump such that the at least one electric motor is adapted to power the at least one fracturing pump;
- providing 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;
- and
- providing at least one blender adapted to supply fracturing fluid comprising a liquefied petroleum gas to the at least one fracturing pump, the blender comprising a first discharge pump, and a second discharge pump;
- pumping the fracturing fluid via fracturing pump into a wellbore at a well site,
