Wireline power supply during electric powered fracturing operations
A system and method for supplying electric power to various pieces of fracturing equipment in a fracturing operation with gas powered generators. The system and method also includes switch gears, auxiliary trailers, transformers, power distribution panels, new receptacles, and cables to supply three-phase power to electric fracturing equipment. The switchgear in the power supply system is weatherproof and able to endure the wear and tear of mobilization. The novel system and method provide clean and quiet electricity to all the equipment on site.
1. A fracturing system comprising:
a turbine generator having an electrical output;
an electric motor that is in electrical communication with the electrical output;
a variable frequency drive (VFD) connected to the electric motor to perform electric motor diagnostics to prevent damage to the electric motor;
a fracturing pump that is driven by the electric motor;
at least one weatherproofed switchgear trailer connected to the at least one turbine; and
a wireline system that is in electrical communication with the electrical output via the at least one weatherproofed switchgear trailer, wherein the electrical output provided to the wireline system is adjusted via one or more transformers positioned between the at least one weatherproofed switchgear trailer and the wireline system.
2. The fracturing system of claim 1 , wherein the wireline system comprises a wireline tool that is disposable in a wellbore that is selected from the group consisting of a perforating gun, a plug, a formation logging tool, a cutting tool, a casing imaging tool, and combinations thereof.
3. The fracturing system of claim 1 , further comprising trailers that contain at least one power distribution panel.
4. The fracturing system of claim 3 , where the trailers further contain receptacles for attaching cables that can sustain a power draw of equipment with three separate plugs for three phase power.
5. The fracturing system of claim 1 , further comprising:
one or more fracturing transformers associated with the fracturing pump, wherein the one or more fracturing transformers are 3500 KVA transformers to step 13.8 kV power from the turbine generator down.
6. The fracturing system of claim 1 , further comprising:
a second VFD that supplies power and controls a blender discharge motor, wherein the blender discharge motor is speed controlled.
7. The fracturing system of claim 1 , wherein the one or more transformers are separate from different transformers associated with the fracturing pump.
8. The fracturing system of claim 1 , wherein the one or more transformers are configured to create a power grid separate from a fracturing power grid configured to power the electric motor.
9. The fracturing system of claim 1 , wherein the one or more transformers comprise at least one emergency shut-off switch.
10. The fracturing system of claim 9 , further comprising:
a datavan configured to provide control signals to the one or more transformers, wherein responsive to a signal from the datavan, the at least one emergency shut-off switch disconnects power provided to the wireline system.
11. The fracturing system of claim 1 , further comprising:
a pump trailer supporting the electric motor, the fracturing pump, and the VFD.
