Abstract

A method of operations in a subterranean formation, including driving a pump with an electrically powered motor to pressurize fluid, inserting a tool into a wellbore that intersects the formation, and directing the pressurized fluid into the wellbore above the tool to push the tool into the wellbore.

Claims

1. A method of operations in a subterranean formation, the method comprising:

driving a pump with an electrically powered motor to pressurize fluid;

inserting a tool into a wellbore that intersects the formation;

pressurizing fluid upstream of the pump to form a boost fluid;

directing the boost fluid to the pump; and

directing the pressurized fluid downstream of the pump and into the wellbore upstream of the tool to push the tool into the wellbore.

2. The method of claim 1, further comprising urging the tool into the wellbore with the pressurized fluid until the tool reaches a predetermined location in the formation.

3. The method of claim 1, wherein the tool comprises a perforating gun.

4. The method of claim 1, wherein the wellbore comprises a first wellbore, and wherein the pressurized fluid is simultaneously directed to a second wellbore that also intersects the subterranean formation.

5. The method of claim 4, wherein hydraulic fracturing is performed in the second wellbore.

6. The method of claim 5, wherein the pump comprises a first pump and a second pump, and wherein fluid pressurized by the first pump is directed into the first wellbore to push the tool into the first wellbore, and fluid pressurized by the second pump is directed into the second wellbore to use in hydraulic fracturing.

7. The method of claim 1, wherein the boost fluid is pressurized via an electric blender.

8. The method of claim 1, wherein electricity that powers the motor is generated with a generator that is proximate the electric motor.

9. The method of claim 8, wherein a wireline system is powered by the electricity.

10. A method of inserting a tool in a subterranean formation, the method comprising:

positioning a trailer having a pump driven by an electric motor at a well site;

positioning a second trailer having a boost pump at the well site;

pressurizing fluid with the boost pump to form a boost fluid;

directing the boost fluid to the pump; and

driving the tool into the subterranean formation via the pump.

11. The method of claim 10, further comprising generating electricity by a turbine generator to power the electric motor.

12. The method of claim 10, further comprising positioning a sand conveyer and hydration unit at the well site.

13. The method of claim 10, further comprising using a first fluid pressurized by the pump to fracture the formation, and using a second fluid that is pressurized by the pump in a pump down operation.

14. The method of claim 13, wherein the first fluid is directed to a first wellbore that intersects the formation, and the second fluid is directed to a second wellbore that intersects the formation.
