System for fueling electric powered hydraulic fracturing equipment with multiple fuel sources
CAFCFirst Claim
1. A hydraulic fracturing system for fracturing a subterranean formation comprising:
- a plurality of electric pumps fluidly connected to a well associated with the subterranean formation and powered by at least one electric motor, 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;
at least one generator electrically coupled to the plurality of electric pumps so as to generate electricity for use by the plurality of electric pumps;
a gas compression system fluidly coupled to the at least one generator so as to provide fuel for use by the at least one generator;
an inert gas source providing an inert gas to regulate the fuel provided to the at least one generator; and
a combustible fuel vaporization system gaseously coupled to the gas compression system so as to provide at least one of vaporized fuel or gasified fuel, or a combination thereof, to the gas compression system.
