Abstract: A hydraulic fracturing system includes a pump, an electrically powered motor for driving the pump, a trailer on which the pump and motor are mounted, and a transformer that steps down electricity for use by the motor. Electrical output from the transformer connects to a series of receptacles mounted onto a housing around the transformer. A similar set of receptacles is provided on the trailer and which are electrically connected to the motor. Power cables equipped with plugs on their opposing ends insert into the receptacles to close an electrical circuit between the transformer and pump.

Abstract: A hydraulic fracturing system for fracturing a subterranean formation is disclosed. In an embodiment, the system may include a plurality of electric pumps fluidly connected to a well associated with the subterranean formation and powered by at least one electric motor, and configured to pump fluid into a wellbore associated with the well at a high pressure so that the fluid passes from the wellbore into the subterranean formation and fractures the subterranean formation; at least one generator electrically coupled to the plurality of electric pumps so as to generate electricity for use by the plurality of electric pumps; and at least one switchgear electrically coupled to the at least one generator and configured to distribute an electrical load between the plurality of electric pumps and the at least one generator.

Abstract: A system for hydraulically fracturing an underground formation in an oil or gas well, including a pump for pumping hydraulic fracturing fluid into the wellbore, the pump having a pump shaft, and an electric motor with a motor shaft mechanically attached to the pump to drive the pump. The system further includes a torsional coupling connecting the motor shaft to the pump shaft. The torsional coupling includes a motor component fixedly attached to the motor shaft and having motor coupling claws extending outwardly away from the motor shaft, and a pump component fixedly attached to the pump shaft of the pump and having pump coupling claws extending outwardly away from the pump shaft. The motor coupling claws engage with the pump coupling claws so that when the motor shaft and motor component rotate, such rotation causes the pump component and the pump shaft to rotate, thereby driving the pump.

Abstract: A hydraulic fracturing system includes an electrically powered pump that pressurizes fluid, which is piped into a wellbore to fracture a subterranean formation. System components include a fluid source, an additive source, a hydration unit, a blending unit, a proppant source, and a fracturing pump. The system includes heaters for warming hydraulic fluid and/or lube oil. The hydraulic fluid is used for operating devices on the blending and hydration units. The lube oil lubricates and cools various moving parts on the fracturing pump.

Abstract: A system for powering equipment used in a hydraulic fracturing operation, the system including at least one first generator in electrical communication with a first switchgear for providing power to primary components of a hydraulic fracturing operation, and at least one second generator in electrical communication with a second switchgear for providing power to backup components of a hydraulic fracturing operation. The at least one first generator is independent of the at least one second generator so that if the at least one first generator loses the ability to generate electricity, the at least one second generator can continue to generate electricity.

Abstract: A hydraulic fracturing system has a pump driven by an electrically powered motor. The pump pressurizes fluid which is piped into a wellbore to fracture a subterranean formation. The pump and motor are mounted on a trailer that is hitched to a tractor. A platform assembly is mounted onto the trailer, and which is selectively moveable between deployed and stowed configurations. The platform assembly includes a platform, a lateral rail assembly mounted to the platform, and gates on the forward and aft ends of the platform. The rail assembly and gates define a safety barrier to prevent operations personnel from falling off the platform. In the stowed configuration the platform assembly is anchored in place over wheels on the trailer. In the deployed configuration, the platform assembly provides work surface so that operations personnel can readily access the pump on the trailer.
