Hybrid Drive Systems for Well Stimulation Operations

A non-transitory computer-readable medium comprising instructions that are configured, when executed by a processor, to:

• determine whether a well stimulation pump is in
• an active period in which the well stimulation pump is engaged to pump fluid to a wellbore,
• an inactive period in which the well stimulation pump is not engaged to pump fluid to the wellbore, or
• a transition period between the inactive period and the active period for pumping fluid to the wellbore;
• energize a first mover configured to generate first mechanical energy from a first fuel or first energy for driving the well stimulation pump;
• and
• energize a second mover configured to generate second mechanical energy from a second fuel or second energy for driving the well stimulation pump,
• wherein the second fuel or second energy is a different type of fuel or energy from the first fuel or first energy,
• wherein at least the first mover is energized if the well stimulation pump is in the active period or the inactive period.
