Refueling system for supplying fuel to fracturing equipment

A refueling system for supplying fuel to at least one piece of fracturing equipment, the refueling system comprising:

• a) a main fuel source fluidly connected to the at least one piece of fracturing equipment;
• and
• b) at least one pressurization unit fluidly connected to the main fuel source, the at least one pressurization unit comprising:
• i. a supply coupling device connected to an onboard motor, the supply coupling device for receiving the fuel from one or more supply fuel lines from the main fuel source;
• and
• ii. a return coupling device for receiving the fuel from the onboard motor and transferring the fuel through one or more return fuel lines to the main fuel source;
• and
• wherein the at least one piece of fracturing equipment operates in a manner whereby a high pressure frac slurry is injected into a well.

A fueling system for a frac operation, the system comprising:

• a first fuel supply line for at least one pressurization unit, the unit configured to provide pressurized fluid to a well, and further comprising a pump, a motor, and a motor fuel source;
• a supply coupling device connected to the first fuel supply line;
• a second fuel supply line connected between the coupling device and a main fuel source, wherein the main fuel source is configured to provide fuel to the at least one pressurization unit;
• a third fuel line connected between the motor fuel source and the coupling device;
• and
• a return fuel line configured to provide fuel transport from the at least one pressurization unit to the main fuel source;
• and
• wherein the motor operates to drive the pump in a manner whereby a high pressure frac slurry is injected into the well.
