Abstract
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.
Claims15
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.
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.
