Benefits of technology

[0011]In still other embodiments, a system for lubricating hydraulic fracturing equipment may comprise an oil pump for pumping lubricating oil, an electric motor configured to drive the oil pump, a variable frequency drive configured to control the electric motor, an oil tank, and a lubricating circuit in fluid communication with the oil pump and the oil tank. The lubricating circuit may pass through the hydraulic fracturing equipment. The variable frequency drive may vary the oil pump speed based on an input comprising at least one of oil pressure and oil temperature. The system may further include at least one of a filter, a thermostatic valve, an oil cooler, a check valve, a pressure relief valve. The thermostatic valve may control a flow of oil through the oil cooler based on oil temperature. The oil tank may be positioned beneath the hydraulic fracturing equipment. The hydraulic fracturing equipme

Abstract

A system for fracturing a subsurface formation may comprise a transport unit with hydraulic legs, an electric motor mounted on the transport unit, a fracking pump mounted on the transport unit and configured to be powered by the electric motor, and an oil tank mounted on the transport unit such that the motor and the fracking pump are above the oil tank. The oil tank may have a first tank height under the pump and a second tank height under the motor and the first tank height may be greater than the second tank height. The oil tank, motor support beam, and pump support beam may form a single structural unit. The system may also include an oil pump for pumping lubricating oil through the fracking pump, an electric motor configured to drive the oil pump, a variable frequency drive configured to control the electric motor.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a nonprovisional application which claims priority from U.S. provisional application No. 62 / 833,385, filed Apr. 12, 2019, which is incorporated by reference herein in its entirety.[0002]Technical Field / Field of the Disclosure[0003]The present disclosure relates to apparatus and methods for use in hydraulically fracturing subsurface formations.BACKGROUND OF THE DISCLOSURE[0004]Hydraulic fracturing may be used to increase hydrocarbon production from some subsurface formations. Hydraulic fracturing entails injecting fluid into a wellbore at a pressure sufficient to cause fissures in the formation surrounding the wellbore. The injected fluid may be a slurry or mixture containing any of a variety of water-, oil-, or gas-based fluids and a proppant and / or other desired additives.[0005]In some instances, the fracturing fluid is pressurized at the surface by high-pressure pumps powered by diesel engines. In other instances, el...
