Well treatment using electric submersible pumping system
A technique provides an electric submersible pumping system to facilitate a well treatment, such as a hydraulic fracturing well treatment. The electric submersible pumping system is positioned downhole and oriented to intake a fluid delivered downhole for use in the well treatment. Once the fluid is delivered downhole, the electric submersible pumping system pumps, pressurizes and discharges this fluid to perform the well treatment, e.g. the hydraulic fracturing treatment. The pumping system reduces the pressure at which the treatment fluid must be delivered downhole.
1. A method, comprising:
deploying an electric submersible pumping system comprising a pump downhole on a conveyance;
locating an intake of the electric submersible pumping system uphole from a packer and a discharge of the electric submersible pumping system downhole from the packer;
delivering a fracturing fluid downhole to the electric submersible pumping system through an annulus between a well casing and the conveyance; and
operating the electric submersible pumping system to deliver a fracturing fluid downhole of the packer through an annulus between the well casing and the pump to stimulate a well zone.
2. The method as recited in claim 1 , wherein deploying comprises deploying the electric submersible pumping system on coiled tubing.
3. The method as recited in claim 1 , wherein delivering comprises delivering the fracturing fluid downhole to the electric submersible pumping system through an annulus surrounding the conveyance.
4. The method as recited in claim 1 , further comprising measuring pressure below the packer.
5. The method as recited in claim 1 , further comprising measuring pressure above the packer.
6. The method as recited in claim 1 , further comprising varying the operational speed of the electric submersible pumping system to vary the pressure wave used to stimulate the well zone.
7. The method as recited in claim 1 , further comprising: moving the electric submersible pumping system to another well location; and stimulating another well zone.
8. The method as recited in claim 7 , wherein moving comprises unsetting and resetting the packer.
9. The method as recited in claim 1 , further comprising running a perforating assembly downhole with electric submersible pumping system to perforate one or more well zones.
10. A system, comprising:
an electric submersible pumping system having an electric submersible pump comprising an intake and a discharge, the intake being on an uphole side of the discharge;
a conveyance coupled to the electric submersible pumping system to deploy the system into a wellbore; and
a packer positioned around the electric submersible pump such that the intake is above the packer and the discharge is below the packer, wherein a fracturing fluid is delivered through an annulus between as well casing and the conveyance and is taken into the intake above the packer and discharged through the discharge below the packer to perform a fracturing operation.
11. The system as recited in claim 10 , wherein the conveyance comprises a coiled tubing coupled to the electric submersible pumping system to deploy the electric submersible pumping system into a wellbore.
12. The system as recited in claim 11 , wherein the intake is positioned to intake fracturing fluid from an annulus surrounding the coiled tubing.
13. The system as recited in claim 10 , further comprising a pressure sensor located on a downhole side of the packer.
14. The system as recited in claim 10 , further comprising a pressure sensor located on a uphole side of the packer.
15. The system as recited in claim 10 , further comprising a perforating gun coupled to the electric submersible pumping system.
