Abstract: A refueling method for supplying fuel to at least one piece of fracturing equipment by installing a main fuel source at a fractionation operation, connecting the main fuel source to fracturing equipment to provide downhole fluids to the well, and connecting at least one pressurization unit to the main fuel source. The method includes using a supply coupling device for receiving fuel from one or more supply fuel lines in communication with the main fuel source and providing the fuel to a motor. The method includes using a return coupling device for receiving fuel from the motor and transferring the fuel through one or more return fuel lines to the main fuel source.

Abstract: A refueling system for supplying fuel to at least one piece of fracturing equipment. The refueling system can have a main fuel source and at least one pressurization unit. The pressurization unit can have an optional pump, a motor, a motor fuel source, a supply coupling device and a return coupling device. The refueling system can have sensors in the one or more supply fuel lines and in the one or more return fuel lines for receiving flow rate information and pressure information, wherein the flow rate information and pressure information are compared to preset limits and a message can be transmitted when the flow rate information and pressure information falls below or exceeds the preset limits to adjust rates of operation.

Abstract: A refueling method for supplying fuel to at least one piece of fracturing equipment by installing a main fuel source at a fractionation operation, connecting the main fuel source to fracturing equipment to provide downhole fluids to the well, and connecting at least one pressurization unit to the main fuel source. The method includes using a valve element to stop fuel flow from the fuel tank when the main fuel source supplies the fuel to the supply coupling device and allows fuel flow from the fuel tank to the at least one pressurization unit when a system failure prevents the main fuel source from supplying fuel to the supply coupling device and using the return fuel line with the return coupling device for the transfer of the fuel to the fuel tank when a system failure prevents the main fuel source from supplying the fuel to the supply coupling device.

Abstract: A refueling method for supplying fuel to hydraulic fracturing equipment by installing a main fuel source at a fractionation operation, connecting the main fuel source to hydraulic fracturing equipment to provide downhole fluids to the well, and connecting at least one pressurization unit to the main fuel source. The method includes using a valve element to stop fuel flow from the motor fuel tank when the main fuel source supplies the fuel to the supply coupling device and automatically starts fuel flow from the motor fuel tank to the pump when a system failure prevents the main fuel source from supplying the fuel to the supply coupling device and using the return fuel line with the return coupling device for the transfer of the fuel to the motor fuel tank when a system failure prevents the main fuel source from supplying the fuel to the supply coupling device.

The method includes using a valve element to stop fuel flow from the motor fuel tank when the main fuel source supplies the fuel to the supply coupling device and automatically starts fuel flow from the motor fuel tank to the pump when a system failure prevents the main fuel source from suppling the fuel to the supply coupling device and using the return fuel line with the return coupling device for the transfer of the fuel to the motor fuel tank when a system failure prevents the main fuel source from supplying the fuel to the supply coupling device.
