Abstract: An electric power generating system is provided that uses a wind turbine to generate waste-heat that is utilized in an organic Rankine Cycle drive that converts heat energy into rotation of a generator rotor for generating electricity. A hydrodynamic retarder may be provided that dissipates heat into a hot fluid by directing the flow of the fluid through the hydrodynamic retarder in a manner that resists rotation of blades of the wind turbine. The hot fluid circulating in the hydrodynamic retarder is a thermal heat source for vapor regeneration of organic heat exchange fluid mixture(s) used in the Rankine cycle, expansion of the organic heat exchange fluid being converted into rotation of the generator rotor.

Abstract: An electrically driven oilfield pumping system may include a compound electro- hydraulic fracturing (frac) pump system that has a primary electric motor that selectively delivers power to one or more of at least two fracturing (frac) pumps. The primary electric motor may be a constant speed alternative cunent (AC) motor with a fixed rated speed.

Abstract: An oilfield pressure pumping system is configured to perform a preliminary' fracturing stage or operation at a high pressure but slow speed before initiating normal fracturing. The oilfield pressure pumping system includes an auxiliary underdrive system that can drive the transmission at a slower input speed that can be provided by an idle speed of the power unit's engine to facilitate different fracturing modes, including a preliminary fracturing mode during a slow speed / high pressure preliminary fracturing stage. The auxiliary underdrive system may include a hydrostatic transmission driven by the engine and which, drives the transmission at an underdrive speed that would correspond to a sub-idle engine speed driving the transmission.

Abstract: An electrically driven oilfield blender system is configured to utilize electric motors as electric prime movers to prepare frac slurry and move the frac slurry to an oilfield pressure pumping system or pressure pumper that pumps the frac slurry into a subterranean formation. Each of the prime mover electric motors may operate at a fixed or constant rated speed and may be connected to a transmission that can drive a device such as a feed pump for a mixing tub or an auxiliary device at a variable speed. An electro-hydraulic motor start system includes an electric motor that powers a hydraulic pump. The hydraulic pump drives hydraulic motors that pre-rotate the prime mover electric motors to their rated speeds before they are energized.

Abstract: An electro-hydraulic high-pressure oilfield pumping system includes a fracturing (frac) pump and a primary electric motor as a prime mover that delivers power to the frac pump. The primary electric motor may be a constant speed AC (alternating current) motor. A hydraulic starting motor may rotate a shaft of the primary electric motor to achieve or approximate its fixed rated speed before the primary electric motor is energized. A slow frac hydraulic motor may rotate the shaft of the primary electric motor as a passive torque transmission device that delivers power in a downstream direction through a transmission and to the frac pump.

Abstract: A method of producing subterranean fractures in geologic formations for the extraction of hydrocarbons includes flowing an air and fuel mixture into a well hole. The well hole may then be sealed with a packer plug creating a compression chamber with the air and fuel mixture. A liquid, such as water, may be pumped into the well hole to create pressure in the compression chamber. The build-up of pressure eventually causes auto-ignition of the air and fuel mixture which fractures the formation. The water may then rush into the compression chamber which thermally shocks the area causing additional fractures. The water may vaporize to steam and thoroughly disinfect the well hole eliminating the need for added biocides.
