Mobile fracturing pump transport for hydraulic fracturing of subsurface geological formations

A method for pumping fracturing fluid with a fracturing pump transport that includes an electric prime mover including a motor shaft, a first fracturing pump including a first pump shaft, a second fracturing pump including a second pump shaft, and a driveline that transmits drive of the motor shaft to the first pump shaft, the method comprising:

• selectively moving a coupling using an actuator between an engaged position and a disengaged position, the coupling being disposed on the driveline, the coupling in the engaged position transmitting the drive of the motor shaft to the first pump shaft, and the coupling in the disengaged position isolating the drive of the motor shaft from the first pump shaft, wherein the motor shaft is a dual shaft extending in both directions from the electric prime mover, wherein the electric prime mover is disposed between the first and second fracturing pumps, and wherein the electric prime mover is operable to transmit drive to the second pump shaft to drive the second fracturing pump without driving the first fracturing pump after the coupling in the disengaged position isolates the drive of the motor shaft from the first pump shaft;
• and
• pumping pressurized fracturing fluid into a wellbore using the second fracturing pump without driving the first fracturing pump.
