Benefits of technology

The patent describes a system where high pressure pumps can be operated without damaging their components by using a single variable frequency drive (VFD) or set of VFDs. The VFDs can provide more power than the pumps need, so they can be used with multiple pumps. The pumps can also have a "breakaway" mechanism to disconnect them from the VFD to provide full power to another pump. The VFDs can be positioned at a distance from the pumps to minimize the risk of ignition when pumping flammable materials. This eliminates the need for expensive explosion-proof measures.

Problems solved by technology

Additionally, many hydrocarbon-based fluids are volatile and / or otherwise unsuitable for use at wellbore temperatures and pressures, while lacking the density sufficient to carry many types of proppant.
Conventionally, such equipment is driven / powered using diesel engines, which can be responsible for significant quantities of noise, pollution, and expense at a worksite.
Electric drive systems have been contemplated as an alternative to diesel engines; however, such systems require numerous pieces of equipment, extensive cabling and / or similar conduits, and typically utilize on-site power generation, such as a natural gas turbine engine.
Use of turbine engines and similar equipment may be unsuitable when utilizing fracturing fluids that include flammable components.

Abstract

Systems for stimulation of a formation include a variable frequency drive configured to receive and output medium voltage power and in communication with high pressure pump. A variable frequency drive actuates an electric motor associated with the high pressure pump, such that the pumps pressurizes a fracturing fluid, proppant, or combinations thereof for flowing the fracturing fluid, proppant, or combinations thereof into the formation.
