HYDRAULIC FRACTURING EQUIPMENT WITH NON-HYDRAULIC POWER
First Claim
1. A hydraulic fracturing system for fracturing a subterranean formation comprising:
- an electric pump fluidly connected to a well associated with the subterranean formation, 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;
one or more ancillary units associated with the fluid pumped into the wellbore;
a first motor electrically coupled to the electric pump to operate the electric pump;
one or more second motors, the one or more second motors comprising one or more electric motors, each of the one or more second motors electrically coupled to at least one of the one or more ancillary units to operate the at least one of the one or more ancillary units; and
a plurality of variable-frequency drives (VFD), each VFD connected to at least one of the first motor or the one or more second motors to control the speed of the first motor or the one or more second motors.

Abstract
The present disclosure is directed to a hydraulic fracturing system for fracturing a subterranean formation. In an embodiment, the system can include an electric pump fluidly connected to a well associated with the formation, 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 formation and fractures the formation. The system can further include one or more ancillary units associated with the fluid pumped into the wellbore. The system can further include a first motor electrically coupled to the electric pump to operate the electric pump, and one or more second motors, each of the second motors electrically coupled to each of the ancillary units to operate the one or more ancillary units.

20. A method for powering one or more ancillary units associated with a hydraulic fracturing system, the method comprising:
-
fluidly connecting an electric pump to a well associated with a subterranean formation, the electric pump 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; fluidly connecting the one or more ancillary units with the fluid pumped into the wellbore; electrically coupling a first motor to the electric pump to operate the electric pump; electrically coupling one or more second motors to each of the one or more ancillary units to operate the one or more ancillary units, the one or more second motors comprising an electric motor; and connecting each of a plurality of variable-frequency drives (VFD) to at least one of the first motor or the one or more second motors to control the speed of the first motor or the one or more second motors.
