An electrical submersible pump assembly supported on coiled or continuous tubing. A power cable extends through the coiled tubing for supplying electrical power to the pump assembly. The cable has an outer diameter that is less than the inner diameter of the tubing, resulting in a cable annulus surrounding the cable. Supports attached to the cable fractionally or mechanically engage the cable with the coiled tubing to support the weight of the cable with the tubing. The supports define passages that allow fluid to flow by within the cable annulus from the surface. A port is provided in the coiled tubing at the electrical submersible pump assembly for discharging fluid pumped from the surface down the cable annulus. A tube may be provided to extend downward from the port alongside of the electrical submersible pump. Fluid may be pumped from an upper end of the well down the cable annulus and out of the port to free up sand accumulation on the packer.
